Obstetrics
Part I. Vocabulary
afterbirth胎盘: The placenta, the amnion羊膜, the chorion绒毛膜, some amniotic fluid, blood, and blood clots expelled from the uterus after childbirth.
Alpha-fetoproteinα-胎儿球蛋白，甲胎蛋白: A protein found in the amniotic fluid. Measurements of the level of AFP in the amniotic sac are used for early diagnosis of fetal defects, such as spina bifida脊柱裂 (defective closure of the vertebrae of the spinal column) and anencephaly (congenital absence of the brain and spinal cord).

Part III. Discomfort of Pregnancy
Throughout the pregnancy, the expectant mother will experience various discomforts. It is important that she realize that these will be temporary discomforts and should subside after delivery. It is also important that the health care professional be aware of the difference between discomforts of pregnancy and signs of possible complications of pregnancy. The knowledgeable health care professional will have the responsibility of educating the patient regarding measures for relief of these temporary discomforts. The following list includes, but is not limited to, the more common discomforts of pregnancy.
backache: Backache is common during the second and third trimester of pregnancy and is due to the body's adaptation to the stresses placed upon the back as the pregnancy progresses.
Recommended treatment includes encouraging the best posture possible, wearing comfortable shoes, getting adequate rest, and bending from the knees ----not the waist.
edema: Edema, or swelling, of the lower extremities is not uncommon in pregnancy, particularly as the pregnancy progresses.
Recommended treatment includes elevating the feet and legs when sitting, lying down when resting, drinking plenty of water, and avoiding foods high in sodium. If the edema is present in the hands and face also, it should be reported immediately to the physician because this could be an indication of complications of pregnancy.
fatigue: Fatigue usually occurs during the first trimester of pregnancy, disappears during the second trimester, and returns toward the end of the pregnancy. This is due to the body's adjustment to the stresses of pregnancy.
heartburn: Heartburn is also known as pyrosis (pyr/o=fever, fire + osis=condition). This discomfort occurs mainly in the last few weeks of pregnancy due to the pressure exerted on the esophagus by the enlarged pregnant uterus. This pressure may also cause a return, or reflux, of gastric juices into the esophagus, resulting in a burning sensation ------ a condition known as gastroesophageal reflux.
hemorrhoids痔: hemorrhoids are swollen veins of the rectum and anus that develop as a result of the increasing pressure on the area due to the progressing pregnancy. They usually disappear after delivery, but can cause quite a bit of discomfort in the pregnant female. Recommended treatment includes drinking plenty of fluids to avoid constipation, which causes hemorrhoids to become more severe, soaking in warm water baths, and applying topical anesthetic ointments.
nausea: Nausea usually occurs during the first trimester of pregnancy and is known as "morning sickness". It may occur during the morning only in some individuals, in the afternoon only in some individuals, or may occur throughout the day. Recommended treatment includes eating dry toast or crackers, eating small frequent meals, eating something before taking prenatal vitamins, or drinking fluids between meals instead of with meals.
varicose veins: Varicose veins are twisted, swollen veins that occur as a result of the blood pooling in the legs, due to the added weight (from the pregnancy) to the lower extremities of the body. Recommended treatment includes the use of support hosiery, encouraging the pregnant woman to avoid crossing her legs, regular exercise of walking to increase the blood flow to the legs, and elevation of the feet and legs when sitting.
Part IV. Complication of Pregnancy
abortion: termination of a pregnancy before the fetus has reached a viable age; that is, an age at which the fetus could live outside of the uterine environment.
Spontaneous abortion: A spontaneous abortion is one that occurs on its own, as a result of abnormalities of the maternal environment or abnormalities of the embryo or fetus. Most spontaneous abortions occur within the first three months of pregnancy. Symptoms include vaginal bleeding, rhythmic uterine cramping, continual backache, and a feeling of pressure in the pelvic area. Tissue may or may not be passed through the vagina, depending on the type of abortion. A spontaneous abortion may be a complete abortion in which all products of conception are expelled; an incomplete abortion in which some, but not all products of conception are expelled; a threatened abortion in which the symptoms of an impending abortion are present, but ultrasound indicates that a live fetus is present.
abruptio/Ab'rQpFiEu/ placenta: The premature separation of a normally implanted placenta from the uterine wall, after the pregnancy has passed 20 weeks gestation or during labor ( the birthing process). Abruptio placenta is a dangerous and potentially life-threatening condition for both the mother and the fetus due to the potential for hemorrhage.
When bleeding occurs on the maternal side of the placenta, a clot (hematoma) forms in the area; this can lead to the premature separation of the placenta in the area. The severity of the complications from abruptio placenta depends on the amount of bleeding and the size of the clot that forms. The degree of separation may range from partial to complete, with bleeding being concealed or apparent.
Abruptio placenta does not usually occur alone, but may accompany other complications of pregnancy. Some of the conditions that may increase the risk of abruptio placenta are hypertension, sue of cocaine by the expectant mother, trauma to the abdomen while pregnant (as in injury or abuse), and the presence of a short umbilical cord (creating tension on the placenta during the birth process).
One of the classic symptoms of abruptio placenta is uterine tenderness with a board-like firmness to the abdomen. Additional symptoms include vaginal bleeding accompanied by abdominal or low back pain, or frequent cramplike contractions of the uterus (uterine irritability). If the bleeding is concealed, the patient may display other signs indicative of this, such as tachycardia, hypotension, and restlessness.
Treatment for abruptio placenta usually involves immediate delivery of the fetus by cesarean section if there are signs of fetal distress or if the expectant mother displays sign of hemorrhaging.
ectopic pregnancy: Abnormal implantation of a fertilized ovum outside of the uterine cavity; also called a tubal pregnancy.
Approximately 90 percent of all ectopic pregnancies occur in the fallopian tubes; other sites for ectopic implantation are the ovaries and the abdomen. Rarely are abdominal pregnancies carried to full term.
Possible causes of ectopic pregnancy include scarring of the fallopian tubes due to infections, inflammation, or as a result of surgery, adhesions due to endometriosis, congenital defects causing deformity of the tubes, pregnancy occurring while an IUD (intrauterine device) is in place, and maternal age over 35 years.
Tubal pregnancies usually rupture between 6 and 12 weeks' gestation. Some women do not even realize that they are pregnant, because the more common signs of pregnancy may not be present during the early stage of gestation. Symptoms include vaginal spotting (usually dark) and sharp abdominal pain (usually described as colicky or cramping).
Diagnosis of an ectopic pregnancy is often confirmed with a positive pregnancy test, ruling out other conditions, and transvaginal ultrasonography, which will reveal the absence of a gestational sac within the uterus. The physician may perform a culdocentesis to rule out a ruptured ectopic pregnancy. The aspiration of unclotted blood from the dul-de-sac area may indicate bleeding from a ruptured fallopian tube. The aspiration of clear fluid from the area would rule out a ruptured fallopian tube.
If ultrasound and culdocentesis are inconclusive and symptoms indicate the possibility of an ectopic pregnancy, laparoscopy may be necessary to confirm the diagnosis of an ectopic pregnancy.
For an unruptured ectopic pregnancy (tubal pregnancy), treatment includes surgery to remove the products of conception from the area. A ruptured ectopic pregnancy is much more serious, with the potential being present for hemorrhage and hypovolemic shock (diminished blood volume). The affected tube is surgically removed (salpingectomy) and the bleeding is brought under control by tying (ligating) the bleeding vessels.
gestational diabetes: A disorder in which women who are not diabetic before pregnancy develop diabetes during the pregnancy; that is, they develop an inability to metabolize carbohydrates (glucose intolerance), with resultant hyperglycemia.
This disorder develops during the latter part of pregnancy, with symptoms usually disappearing at the end of the pregnancy. Women who have gestational diabetes have a higher possibility of developing it with subsequent pregnancies; they are also at higher risk of developing diabetes later in life.
Factors that increase the risk of developing gestational diabetes include, but are not limited to, the following: obesity; maternal age over 30 years of age; history or birthing large babies (usually over 10 pounds); family history of diabetes; previous, unexplained, stillborn birth; previous birth with congenital anomalies (defects).
Symptoms vary from classic symptoms of diabetes, such as excessive thirst, hunger, and frequent urination, to being asymptomatic. Because a high number of pregnant women have gestational diabetes without obvious symptoms, all pregnant women are routinely screened for diabetes with a blood test; this usually occurs between weeks 24 and 28 of the pregnancy.
hydatidiform mole/high-dah-TID-ih-form/葡萄胎: An abnormal condition that begins as a pregnancy and deviates from normal development very early; the diseased ovum deteriorates (not producing a fetus), and the chorionic villi of the placenta (small vessels protruding from the outer layer) change to a mass of cysts resembling a bunch of grapes.
The growth of this mass progresses much more rapidly than uterine growth with a normal pregnancy. A hydatidiform mole is known as a molar pregnancy; also called a hydatid mole.
Symptoms include, but are not limited to, extreme nausea, uterine bleeding, anemia, an unusually large uterus for the duration of pregnancy (at three months the uterus may be the size expected at 5 or 6 months), absence of fetal heart sounds, edema, and hypertension.
Diagnosis is confirmed through the use of ultrasonography (no fetal skeleton will be visible), and laboratory findings ( the HCG level will be extremely high).
Treatment options include evacuation of the uterus, followed by a dilation and curettage when the uterine wall has regained its firmness (a few days later) or a hysterectomy, in which the uterus is removed. The age of the woman and the condition of the uterus will be factors determining the need for a hysterectomy. The tissue from the mass will be tested for presence of malignant cell.
Follow-up treatment involves close medical supervision for about 1 year following a molar pregnancy. This will include careful monitoring of the HCG levels (until they return to normal), and avoidance of another pregnancy for at least a year after all tests are negative. If no malignancy is detected and the HCG levels decrease, the prognosis is favorable.
hyperemesis gravidarum/high-per-EM-eh-sis grav-ih-DAR-um/妊娠剧吐: An abnormal condition of pregnancy characterized by severe vomiting that results in maternal dehydration, and weight loss.
The nausea and vomiting associated with hyperemesis gravidarum persists beyond the first three months of pregnancy and persists throughout the day to the point that eventually nothing can be retained by mouth.
The exact cause of this condition is unknown, but the incidence seems to be greater in younger mothers, first-time mothers, and those with increased body weight. Psychological factors have been considered as being instrumental in the development of hyperemesis graviarum (such as stress over the pregnancy, ambivalent feelings, toward the pregnancy, and conflicting feelings over becoming a mother). There are physical factors as well such as hyperthyroidism, elevated levels of estrogen, a multiple pregnancy, and the presence of a hydatidiform mole.
Treatment includes control of the vomiting, replacement of lost fluids and electrolytes, and emotional support for the woman. In most women, hyperemesis gravidarum is self-limiting and health is restored.
incompetent cervix: A condition in which the cervical os (opening) dilates before the fetus reaches term, without labor or uterine contractions; usually occurring during the second trimester of pregnancy and resulting in a spontaneous abortion of the fetus.
Treatment for an incompetent cervix involves suturing the cervix to keep it from opening during the pregnancy; this is known as cerclage. If the woman is going to have a vaginal delivery, the sutures are removed near the end of the pregnancy. If she is to have a cesarean section delivery, the sutures may be left in place.
placenta previa前置胎盘/plah-SEN-tah PRE-vee-ah/: A condition of pregnancy in which the placenta is implanted in the lower part of the uterus, and precedes the fetus during the birthing process. The cause (etiology) is unknown.
The degree of previa may range from marginal previa, where the placenta barely comes to the edge of the cervical os to partial previa, where the placenta partially covers the cervical os to total previa, where the placenta completely covers the cervical os.
The classic symptom of placenta previa is painless bleeding during the third trimester of pregnancy. The bleeding is usually abrupt and bright red, and very frightening to the expectant mother.
Diagnosis of placenta previa is confirmed by ultrasonography; sometimes it is detected before symptoms occur, through routine use of ultrasonography.
Treatment ranges from conservative measures of bed rest to immediate delivery by cesarean section, depending on the condition of the expectant mother and the condition of the fetus; that is, maturity of fetus and whether or not fetal distress is detected.
pregnancy-induced hypertension: Pregnancy-induced hypertension is the development of hypertension (high blood pressure) during pregnancy, in women who had normal blood pressure readings (normotensive) prior to pregnancy.
For ease in understanding, pregnancy-induced hypertension (PIH) is divided into three categories based on degree of severity:
1. Gestational hypertension is the development of hypertension after 20 weeks' gestation with no signs of edema or proteinuria. A blood pressure reading of 140/90 mmHg or greater on more than one occasion, or a blood pressure reading of 30 mmHg systolic or 15 mmHg diastolic over the patient's normal baseline readings are indicative of gestational hypertension. The hypertension usually subsides after pregnancy.
2. Pre-eclampsia is the development of hypertension with proteinuria or edema, after 20 weeks' gestation. The factor that distinguishes pre-eclampsia from gestational hypertension is the presence of proteinuria. The patient may also exhibit edema of the hands and face.
Edema of the feet and legs is common during pregnancy; however, edema that occurs above the waist may be indicative of pregnancy-induced hypertension. One of the first signs of edema may be a sudden rapid weight gain of more than 4 pounds in one week. This may be followed by visible signs of edema, such as puffiness or swelling of the face and hands; the woman may remove the rings from her fingers as they seem increasingly tighter on the fingers.
If the condition worsens, the pre-eclamptic patient may experience blurred vision or see spots in front of her eyes, and complain of severe headaches. These symptoms are strong indicators of impending eclampsia and medical treatment will be necessary.
3. Eclampsia子痫 is the most severe form of hypertension during pregnancy and is evidenced by the presence of seizures. An eclamptic seizure may jeopardize the life of the expectant mother and her fetus.
Delivery of the baby is the cure for pregnancy-induced hypertension. If it is determined that the fetus is mature enough for delivery, the pregnancy is ended by inducing labor or by performing a cesarean section. If the fetus is not mature enough for delivery, medical treatment will involve hospitalization of the expectant mother, bed rest, administration of medications to prevent convulsions until the baby can be delivered.
Rh incompatibility: An incompatibility between an Rh negative mother's blood with her Rh positive baby's blood, causing the mother's body to develop antibodies that will destroy the Rh positive blood.
Rh incompatibility can occur if the father of the baby is Rh positive and the mother of the baby is Rh negative; it does not occur when the expectant mother is Rh positive.
An Rh negative mother will give birth to either an Rh negative baby or an Rh positive baby. If her baby is Rh negative, the two are compatible. If her baby is Rh positive, the potential for incompatibility in subsequent births is present. During the birth process, if there is a mixing of Rh negative maternal and Rh positive fetal blood (as the placenta separates from the uterine wall), the mother's blood will recognize this as foreign to her body and will respond by producing antibodies to destroy the Rh positive blood.
The first Rh positive baby born to an Rh negative mother will not be affected by an Rh incompatibility; however, the antibodies that develop in response to the first pregnancy will be present during subsequent pregnancies. If a subsequent pregnancy produces an Rh positive fetus, the antibody production will increase. These antibodies are small enough to cross the placental barrier into the fetal circulation and destroy the red blood cells of the fetus, which have been recognized as "foreign" to the mother's body.
Treatment for preventionof Rh incompatibility is to administer an injection of Rh immune globulin (RhoGAM) to the Rh negative, pregnant woman during the 28th week of pregnancy. If she gives birth to an Rh positive baby, she will be administered another injection of RhoGAM within 72 hours after the birth. The administration of this Rh immune globulin will prevent the formation of the antibodies in the Rh negative mother's blood.
It is important that an Rh negative woman realizes that if her first pregnancy ends in abortion, it is still counted as a pregnancy and she should receive the injection of RhoGAM after the abortion to prevent the formation of antibodies that will affect future pregnancies, should the fetus be Rh positive.
Part V. Signs and Symptoms of Labor
The following is an elementary discussion of the signs and symptoms of impending labor and comparison of true labor and false labor.
bloody show: a vaginal discharge that is a mixture of thick mucus and pink or dark brown blood. It may begin a few weeks prior to the onset of labor and occurs as a result of the softening, dilation, and effacement (thinning) of the cervix in preparation for childbirth. The bloody show will continue and will increase during labor as the cervix continues to dilate and efface..
Braxton Hicks contractions: mild, irregular contractions that occur throughout pregnancy. As full term approaches, these contractions intensify and are sometimes mistaken for true labor.
increased vaginal discharge: This occurs when the baby settles into the pelvis prior to the onset of labor. The pressure of the baby's head in the area creates congestion of the vaginal mucosa, which results in an increase in clear, nonirritating vaginal secretions.
The expectant mother will notice that she can breathe easier because the descent of the baby relieves some of the pressure from her diaphragm. When lightening occurs, most expectant mothers will refer to it by saying that the baby has "dropped". Lightening is more obvious in women who are having their first baby.
rupture of the amniotic sac: The amniotic sac may occur prior to the onset of labor, may occur during labor, or may not occur without assistance. Expectant mothers are usually advised to report to the hospital or birthing center for evaluation if the membranes rupture prior to the onset of labor. This is important because the amniotic sac serves as a barrier between the baby and the unsterile outside environment, and when it is broken, the chance for infection is increased. Women often refer to the rupture of the amniotic sac by saying "water broke," because there may be a sudden gush of amniotic fluid as the membranes rupture.
sudden burst of energy: This occurs in some women shortly before the onset of labor. These women may suddenly have the energy to do major housecleaning duties ---- things they have not had the energy to do previously. They should be cautioned to save their energy during this time, so they will not be fatigued when labor actually begins.

Part VI. Diagnostic Techniques
amniocentesis: a surgical puncture of the amniotic sac for the purpose of removing amniotic fluid.
A needle is passed through the abdomen and uterus into the amniotic sac. Fluid is
removed for laboratory analysis to detect fetal abnormalities, maternal-fetal
blood incompatibilities, and to determine fetal maturity. If necessary, an
amniocentesis is usually performed between the 16th and 20th week of gestation.
cesarean section: a surgical procedure in which the abdomen and uterus are incised and a baby is
delivered transabdominally.
It is performed when abnormal fetal or maternal conditions exist that are judged
likely to make a vaginal delivery hazardous.
contraction stress test宫缩应急试验: a stress test used to evaluate the ability of the fetus to tolerate the stress of labor and delivery (CST); also known as oxytocin challenge test. The purpose of the oxytocin challenge test is to simulate labor for a measurable period of time to determine whether or not the infant will tolerate labor well. During labor, uterine contractions decrease the oxygen supply to the fetus; if there is a significant decrease in the oxygen supply, it may cause a decrease in the fetal heart rate.
The maternal uterine activity and the fetal heart rate are monitored closely
during this stress test. If it appears that the contractions of the uterus will
endanger the fetus as labor progresses, an emergency cesarean section may
be indicated.
fetal monitoring (electronic)胎儿监护: The use of an electronic device to monitor the fetal heart rate and the maternal uterine contractions; this procedure can be done with external or internal devices. This monitoring is valuable during labor to assess the quality of the uterine contractions and the effects of lab or on the fetus.
nipple stimulation test: a noninvasive technique that produces basically the same results as the
contraction stress test by having the pregnant woman stimulate the nipples
of her breasts by rubbing them between her fingers.
This causes the natural release of oxytocin that causes contractions of the
uterus. The nipple stimulation test is less stressing to the uterus.
pelvic utrasound: a noninvasive procedure that uses high-frequency sound waves to examine
the abdomen and pelvis. The sound waves pass through the abdominal wall
from the transducer, which is moved back and forth across the abdomen.
When the sound waves bounce off of the internal organs in the
abdominopelvic region, these waves are converted to electrical impulses
eventually recorded on an oscilloscope screen. A photograph of the images is
then taken for further study.
Pelvic ultrasound can be used to locate a pelvic mass, an ectopic pregnancy, or
an intrauterine device, to inspect and assess the uterus, ovaries, and fallopian
tubes. Clearer ultrasonic pictures of the pelvic organs can be obtained by using
transvaginal ultrasonography. This procedure produces the same type of
picture as abdominal ultrasound, but involves the use of a vagina probe
inserted into the vagina while the patient is in lithotomy position. The probes
are encased in a sterile sheath and placed in the transducer before it is inserted
into the vagina. The sound waves function in the same way as those for the
abdominopelvic ultrasound, but the transvaginal ultrasonic image is much
clearer.
pelvimetry: The process of measuring the female pelvis, manually or by x-ray, to determine its
adequacy for childbearing.
Clinical pelvimetry is an estimate of the size of the birth canal by vaginal palpation
of bony landmarks in the pelvis and a mathematical estimate of the distance
between them. This is performed during the early part of the pregnancy and is r
ecorded as "adequate", "borderline", or "inadequate".
X-ray pevimetry is an actual x-ray of the pelvis to determine the dimensions of the
bony pelvis of a pregnant woman; it is performed when there is doubt that the head
of the fetus can safely pass through the pelvis during the labor process.
Measurements are actually made on the x-ray, and the true dimensions of the birth
canal and the head of the fetus can be calculated to determine if the proportions are
suitable.
pregnancy testing: tests performed on maternal urine and/or blood to determine the presence of
the hormone, HCG (human chorionic gonadotropin); HCG is detected shortly after
the first missed menstrual period.
Tests performed on blood are highly reliable and results are usually available in
approximately one hour. Tests performed on urine are fairly accurate when done
correctly, and are very popular in the form of home testing kits; results are
available within minutes. Women using home testing kits should test the first
voided urine specimen of the day, since the level of HCG is highest at that time.

Part III. Discomfort of Pregnancy
Throughout the pregnancy, the expectant mother will experience various discomforts. It is important that she realize that these will be temporary discomforts and should subside after delivery. It is also important that the health care professional be aware of the difference between discomforts of pregnancy and signs of possible complications of pregnancy. The knowledgeable health care professional will have the responsibility of educating the patient regarding measures for relief of these temporary discomforts. The following list includes, but is not limited to, the more common discomforts of pregnancy.
backache: Backache is common during the second and third trimester of pregnancy and is due to the body's adaptation to the stresses placed upon the back as the pregnancy progresses.
Recommended treatment includes encouraging the best posture possible, wearing comfortable shoes, getting adequate rest, and bending from the knees ----not the waist.
edema: Edema, or swelling, of the lower extremities is not uncommon in pregnancy, particularly as the pregnancy progresses.
Recommended treatment includes elevating the feet and legs when sitting, lying down when resting, drinking plenty of water, and avoiding foods high in sodium. If the edema is present in the hands and face also, it should be reported immediately to the physician because this could be an indication of complications of pregnancy.
fatigue: Fatigue usually occurs during the first trimester of pregnancy, disappears during the second trimester, and returns toward the end of the pregnancy. This is due to the body's adjustment to the stresses of pregnancy.
heartburn: Heartburn is also known as pyrosis (pyr/o=fever, fire + osis=condition). This discomfort occurs mainly in the last few weeks of pregnancy due to the pressure exerted on the esophagus by the enlarged pregnant uterus. This pressure may also cause a return, or reflux, of gastric juices into the esophagus, resulting in a burning sensation ------ a condition known as gastroesophageal reflux.
hemorrhoids痔: hemorrhoids are swollen veins of the rectum and anus that develop as a result of the increasing pressure on the area due to the progressing pregnancy. They usually disappear after delivery, but can cause quite a bit of discomfort in the pregnant female. Recommended treatment includes drinking plenty of fluids to avoid constipation, which causes hemorrhoids to become more severe, soaking in warm water baths, and applying topical anesthetic ointments.
nausea: Nausea usually occurs during the first trimester of pregnancy and is known as "morning sickness". It may occur during the morning only in some individuals, in the afternoon only in some individuals, or may occur throughout the day. Recommended treatment includes eating dry toast or crackers, eating small frequent meals, eating something before taking prenatal vitamins, or drinking fluids between meals instead of with meals.
varicose veins: Varicose veins are twisted, swollen veins that occur as a result of the blood pooling in the legs, due to the added weight (from the pregnancy) to the lower extremities of the body. Recommended treatment includes the use of support hosiery, encouraging the pregnant woman to avoid crossing her legs, regular exercise of walking to increase the blood flow to the legs, and elevation of the feet and legs when sitting.
Part IV. Complication of Pregnancy
abortion: termination of a pregnancy before the fetus has reached a viable age; that is, an age at which the fetus could live outside of the uterine environment.
Spontaneous abortion: A spontaneous abortion is one that occurs on its own, as a result of abnormalities of the maternal environment or abnormalities of the embryo or fetus. Most spontaneous abortions occur within the first three months of pregnancy. Symptoms include vaginal bleeding, rhythmic uterine cramping, continual backache, and a feeling of pressure in the pelvic area. Tissue may or may not be passed through the vagina, depending on the type of abortion. A spontaneous abortion may be a complete abortion in which all products of conception are expelled; an incomplete abortion in which some, but not all products of conception are expelled; a threatened abortion in which the symptoms of an impending abortion are present, but ultrasound indicates that a live fetus is present.
abruptio/Ab'rQpFiEu/ placenta: The premature separation of a normally implanted placenta from the uterine wall, after the pregnancy has passed 20 weeks gestation or during labor ( the birthing process). Abruptio placenta is a dangerous and potentially life-threatening condition for both the mother and the fetus due to the potential for hemorrhage.
When bleeding occurs on the maternal side of the placenta, a clot (hematoma) forms in the area; this can lead to the premature separation of the placenta in the area. The severity of the complications from abruptio placenta depends on the amount of bleeding and the size of the clot that forms. The degree of separation may range from partial to complete, with bleeding being concealed or apparent.
Abruptio placenta does not usually occur alone, but may accompany other complications of pregnancy. Some of the conditions that may increase the risk of abruptio placenta are hypertension, sue of cocaine by the expectant mother, trauma to the abdomen while pregnant (as in injury or abuse), and the presence of a short umbilical cord (creating tension on the placenta during the birth process).
One of the classic symptoms of abruptio placenta is uterine tenderness with a board-like firmness to the abdomen. Additional symptoms include vaginal bleeding accompanied by abdominal or low back pain, or frequent cramplike contractions of the uterus (uterine irritability). If the bleeding is concealed, the patient may display other signs indicative of this, such as tachycardia, hypotension, and restlessness.
Treatment for abruptio placenta usually involves immediate delivery of the fetus by cesarean section if there are signs of fetal distress or if the expectant mother displays sign of hemorrhaging.
ectopic pregnancy: Abnormal implantation of a fertilized ovum outside of the uterine cavity; also called a tubal pregnancy.
Approximately 90 percent of all ectopic pregnancies occur in the fallopian tubes; other sites for ectopic implantation are the ovaries and the abdomen. Rarely are abdominal pregnancies carried to full term.
Possible causes of ectopic pregnancy include scarring of the fallopian tubes due to infections, inflammation, or as a result of surgery, adhesions due to endometriosis, congenital defects causing deformity of the tubes, pregnancy occurring while an IUD (intrauterine device) is in place, and maternal age over 35 years.
Tubal pregnancies usually rupture between 6 and 12 weeks' gestation. Some women do not even realize that they are pregnant, because the more common signs of pregnancy may not be present during the early stage of gestation. Symptoms include vaginal spotting (usually dark) and sharp abdominal pain (usually described as colicky or cramping).
Diagnosis of an ectopic pregnancy is often confirmed with a positive pregnancy test, ruling out other conditions, and transvaginal ultrasonography, which will reveal the absence of a gestational sac within the uterus. The physician may perform a culdocentesis to rule out a ruptured ectopic pregnancy. The aspiration of unclotted blood from the dul-de-sac area may indicate bleeding from a ruptured fallopian tube. The aspiration of clear fluid from the area would rule out a ruptured fallopian tube.
If ultrasound and culdocentesis are inconclusive and symptoms indicate the possibility of an ectopic pregnancy, laparoscopy may be necessary to confirm the diagnosis of an ectopic pregnancy.
For an unruptured ectopic pregnancy (tubal pregnancy), treatment includes surgery to remove the products of conception from the area. A ruptured ectopic pregnancy is much more serious, with the potential being present for hemorrhage and hypovolemic shock (diminished blood volume). The affected tube is surgically removed (salpingectomy) and the bleeding is brought under control by tying (ligating) the bleeding vessels.
gestational diabetes: A disorder in which women who are not diabetic before pregnancy develop diabetes during the pregnancy; that is, they develop an inability to metabolize carbohydrates (glucose intolerance), with resultant hyperglycemia.
This disorder develops during the latter part of pregnancy, with symptoms usually disappearing at the end of the pregnancy. Women who have gestational diabetes have a higher possibility of developing it with subsequent pregnancies; they are also at higher risk of developing diabetes later in life.
Factors that increase the risk of developing gestational diabetes include, but are not limited to, the following: obesity; maternal age over 30 years of age; history or birthing large babies (usually over 10 pounds); family history of diabetes; previous, unexplained, stillborn birth; previous birth with congenital anomalies (defects).
Symptoms vary from classic symptoms of diabetes, such as excessive thirst, hunger, and frequent urination, to being asymptomatic. Because a high number of pregnant women have gestational diabetes without obvious symptoms, all pregnant women are routinely screened for diabetes with a blood test; this usually occurs between weeks 24 and 28 of the pregnancy.
hydatidiform mole/high-dah-TID-ih-form/葡萄胎: An abnormal condition that begins as a pregnancy and deviates from normal development very early; the diseased ovum deteriorates (not producing a fetus), and the chorionic villi of the placenta (small vessels protruding from the outer layer) change to a mass of cysts resembling a bunch of grapes.
The growth of this mass progresses much more rapidly than uterine growth with a normal pregnancy. A hydatidiform mole is known as a molar pregnancy; also called a hydatid mole.
Symptoms include, but are not limited to, extreme nausea, uterine bleeding, anemia, an unusually large uterus for the duration of pregnancy (at three months the uterus may be the size expected at 5 or 6 months), absence of fetal heart sounds, edema, and hypertension.
Diagnosis is confirmed through the use of ultrasonography (no fetal skeleton will be visible), and laboratory findings ( the HCG level will be extremely high).
Treatment options include evacuation of the uterus, followed by a dilation and curettage when the uterine wall has regained its firmness (a few days later) or a hysterectomy, in which the uterus is removed. The age of the woman and the condition of the uterus will be factors determining the need for a hysterectomy. The tissue from the mass will be tested for presence of malignant cell.
Follow-up treatment involves close medical supervision for about 1 year following a molar pregnancy. This will include careful monitoring of the HCG levels (until they return to normal), and avoidance of another pregnancy for at least a year after all tests are negative. If no malignancy is detected and the HCG levels decrease, the prognosis is favorable.
hyperemesis gravidarum/high-per-EM-eh-sis grav-ih-DAR-um/妊娠剧吐: An abnormal condition of pregnancy characterized by severe vomiting that results in maternal dehydration, and weight loss.
The nausea and vomiting associated with hyperemesis gravidarum persists beyond the first three months of pregnancy and persists throughout the day to the point that eventually nothing can be retained by mouth.
The exact cause of this condition is unknown, but the incidence seems to be greater in younger mothers, first-time mothers, and those with increased body weight. Psychological factors have been considered as being instrumental in the development of hyperemesis graviarum (such as stress over the pregnancy, ambivalent feelings, toward the pregnancy, and conflicting feelings over becoming a mother). There are physical factors as well such as hyperthyroidism, elevated levels of estrogen, a multiple pregnancy, and the presence of a hydatidiform mole.
Treatment includes control of the vomiting, replacement of lost fluids and electrolytes, and emotional support for the woman. In most women, hyperemesis gravidarum is self-limiting and health is restored.
incompetent cervix: A condition in which the cervical os (opening) dilates before the fetus reaches term, without labor or uterine contractions; usually occurring during the second trimester of pregnancy and resulting in a spontaneous abortion of the fetus.
Treatment for an incompetent cervix involves suturing the cervix to keep it from opening during the pregnancy; this is known as cerclage. If the woman is going to have a vaginal delivery, the sutures are removed near the end of the pregnancy. If she is to have a cesarean section delivery, the sutures may be left in place.
placenta previa前置胎盘/plah-SEN-tah PRE-vee-ah/: A condition of pregnancy in which the placenta is implanted in the lower part of the uterus, and precedes the fetus during the birthing process. The cause (etiology) is unknown.
The degree of previa may range from marginal previa, where the placenta barely comes to the edge of the cervical os to partial previa, where the placenta partially covers the cervical os to total previa, where the placenta completely covers the cervical os.
The classic symptom of placenta previa is painless bleeding during the third trimester of pregnancy. The bleeding is usually abrupt and bright red, and very frightening to the expectant mother.
Diagnosis of placenta previa is confirmed by ultrasonography; sometimes it is detected before symptoms occur, through routine use of ultrasonography.
Treatment ranges from conservative measures of bed rest to immediate delivery by cesarean section, depending on the condition of the expectant mother and the condition of the fetus; that is, maturity of fetus and whether or not fetal distress is detected.
pregnancy-induced hypertension: Pregnancy-induced hypertension is the development of hypertension (high blood pressure) during pregnancy, in women who had normal blood pressure readings (normotensive) prior to pregnancy.
For ease in understanding, pregnancy-induced hypertension (PIH) is divided into three categories based on degree of severity:
1. Gestational hypertension is the development of hypertension after 20 weeks' gestation with no signs of edema or proteinuria. A blood pressure reading of 140/90 mmHg or greater on more than one occasion, or a blood pressure reading of 30 mmHg systolic or 15 mmHg diastolic over the patient's normal baseline readings are indicative of gestational hypertension. The hypertension usually subsides after pregnancy.
2. Pre-eclampsia is the development of hypertension with proteinuria or edema, after 20 weeks' gestation. The factor that distinguishes pre-eclampsia from gestational hypertension is the presence of proteinuria. The patient may also exhibit edema of the hands and face.
Edema of the feet and legs is common during pregnancy; however, edema that occurs above the waist may be indicative of pregnancy-induced hypertension. One of the first signs of edema may be a sudden rapid weight gain of more than 4 pounds in one week. This may be followed by visible signs of edema, such as puffiness or swelling of the face and hands; the woman may remove the rings from her fingers as they seem increasingly tighter on the fingers.
If the condition worsens, the pre-eclamptic patient may experience blurred vision or see spots in front of her eyes, and complain of severe headaches. These symptoms are strong indicators of impending eclampsia and medical treatment will be necessary.
3. Eclampsia子痫 is the most severe form of hypertension during pregnancy and is evidenced by the presence of seizures. An eclamptic seizure may jeopardize the life of the expectant mother and her fetus.
Delivery of the baby is the cure for pregnancy-induced hypertension. If it is determined that the fetus is mature enough for delivery, the pregnancy is ended by inducing labor or by performing a cesarean section. If the fetus is not mature enough for delivery, medical treatment will involve hospitalization of the expectant mother, bed rest, administration of medications to prevent convulsions until the baby can be delivered.
Rh incompatibility: An incompatibility between an Rh negative mother's blood with her Rh positive baby's blood, causing the mother's body to develop antibodies that will destroy the Rh positive blood.
Rh incompatibility can occur if the father of the baby is Rh positive and the mother of the baby is Rh negative; it does not occur when the expectant mother is Rh positive.
An Rh negative mother will give birth to either an Rh negative baby or an Rh positive baby. If her baby is Rh negative, the two are compatible. If her baby is Rh positive, the potential for incompatibility in subsequent births is present. During the birth process, if there is a mixing of Rh negative maternal and Rh positive fetal blood (as the placenta separates from the uterine wall), the mother's blood will recognize this as foreign to her body and will respond by producing antibodies to destroy the Rh positive blood.
The first Rh positive baby born to an Rh negative mother will not be affected by an Rh incompatibility; however, the antibodies that develop in response to the first pregnancy will be present during subsequent pregnancies. If a subsequent pregnancy produces an Rh positive fetus, the antibody production will increase. These antibodies are small enough to cross the placental barrier into the fetal circulation and destroy the red blood cells of the fetus, which have been recognized as "foreign" to the mother's body.
Treatment for preventionof Rh incompatibility is to administer an injection of Rh immune globulin (RhoGAM) to the Rh negative, pregnant woman during the 28th week of pregnancy. If she gives birth to an Rh positive baby, she will be administered another injection of RhoGAM within 72 hours after the birth. The administration of this Rh immune globulin will prevent the formation of the antibodies in the Rh negative mother's blood.
It is important that an Rh negative woman realizes that if her first pregnancy ends in abortion, it is still counted as a pregnancy and she should receive the injection of RhoGAM after the abortion to prevent the formation of antibodies that will affect future pregnancies, should the fetus be Rh positive.
Part V. Signs and Symptoms of Labor
The following is an elementary discussion of the signs and symptoms of impending labor and comparison of true labor and false labor.
bloody show: a vaginal discharge that is a mixture of thick mucus and pink or dark brown blood. It may begin a few weeks prior to the onset of labor and occurs as a result of the softening, dilation, and effacement (thinning) of the cervix in preparation for childbirth. The bloody show will continue and will increase during labor as the cervix continues to dilate and efface..
Braxton Hicks contractions: mild, irregular contractions that occur throughout pregnancy. As full term approaches, these contractions intensify and are sometimes mistaken for true labor.
increased vaginal discharge: This occurs when the baby settles into the pelvis prior to the onset of labor. The pressure of the baby's head in the area creates congestion of the vaginal mucosa, which results in an increase in clear, nonirritating vaginal secretions.
The expectant mother will notice that she can breathe easier because the descent of the baby relieves some of the pressure from her diaphragm. When lightening occurs, most expectant mothers will refer to it by saying that the baby has "dropped". Lightening is more obvious in women who are having their first baby.
rupture of the amniotic sac: The amniotic sac may occur prior to the onset of labor, may occur during labor, or may not occur without assistance. Expectant mothers are usually advised to report to the hospital or birthing center for evaluation if the membranes rupture prior to the onset of labor. This is important because the amniotic sac serves as a barrier between the baby and the unsterile outside environment, and when it is broken, the chance for infection is increased. Women often refer to the rupture of the amniotic sac by saying "water broke," because there may be a sudden gush of amniotic fluid as the membranes rupture.
sudden burst of energy: This occurs in some women shortly before the onset of labor. These women may suddenly have the energy to do major housecleaning duties ---- things they have not had the energy to do previously. They should be cautioned to save their energy during this time, so they will not be fatigued when labor actually begins.

Part VI. Diagnostic Techniques
amniocentesis: a surgical puncture of the amniotic sac for the purpose of removing amniotic fluid.
A needle is passed through the abdomen and uterus into the amniotic sac. Fluid is
removed for laboratory analysis to detect fetal abnormalities, maternal-fetal
blood incompatibilities, and to determine fetal maturity. If necessary, an
amniocentesis is usually performed between the 16th and 20th week of gestation.
cesarean section: a surgical procedure in which the abdomen and uterus are incised and a baby is
delivered transabdominally.
It is performed when abnormal fetal or maternal conditions exist that are judged
likely to make a vaginal delivery hazardous.
contraction stress test宫缩应急试验: a stress test used to evaluate the ability of the fetus to tolerate the stress of labor and delivery (CST); also known as oxytocin challenge test. The purpose of the oxytocin challenge test is to simulate labor for a measurable period of time to determine whether or not the infant will tolerate labor well. During labor, uterine contractions decrease the oxygen supply to the fetus; if there is a significant decrease in the oxygen supply, it may cause a decrease in the fetal heart rate.
The maternal uterine activity and the fetal heart rate are monitored closely
during this stress test. If it appears that the contractions of the uterus will
endanger the fetus as labor progresses, an emergency cesarean section may
be indicated.
fetal monitoring (electronic)胎儿监护: The use of an electronic device to monitor the fetal heart rate and the maternal uterine contractions; this procedure can be done with external or internal devices. This monitoring is valuable during labor to assess the quality of the uterine contractions and the effects of lab or on the fetus.
nipple stimulation test: a noninvasive technique that produces basically the same results as the
contraction stress test by having the pregnant woman stimulate the nipples
of her breasts by rubbing them between her fingers.
This causes the natural release of oxytocin that causes contractions of the
uterus. The nipple stimulation test is less stressing to the uterus.
pelvic utrasound: a noninvasive procedure that uses high-frequency sound waves to examine
the abdomen and pelvis. The sound waves pass through the abdominal wall
from the transducer, which is moved back and forth across the abdomen.
When the sound waves bounce off of the internal organs in the
abdominopelvic region, these waves are converted to electrical impulses
eventually recorded on an oscilloscope screen. A photograph of the images is
then taken for further study.
Pelvic ultrasound can be used to locate a pelvic mass, an ectopic pregnancy, or
an intrauterine device, to inspect and assess the uterus, ovaries, and fallopian
tubes. Clearer ultrasonic pictures of the pelvic organs can be obtained by using
transvaginal ultrasonography. This procedure produces the same type of
picture as abdominal ultrasound, but involves the use of a vagina probe
inserted into the vagina while the patient is in lithotomy position. The probes
are encased in a sterile sheath and placed in the transducer before it is inserted
into the vagina. The sound waves function in the same way as those for the
abdominopelvic ultrasound, but the transvaginal ultrasonic image is much
clearer.
pelvimetry: The process of measuring the female pelvis, manually or by x-ray, to determine its
adequacy for childbearing.
Clinical pelvimetry is an estimate of the size of the birth canal by vaginal palpation
of bony landmarks in the pelvis and a mathematical estimate of the distance
between them. This is performed during the early part of the pregnancy and is r
ecorded as "adequate", "borderline", or "inadequate".
X-ray pevimetry is an actual x-ray of the pelvis to determine the dimensions of the
bony pelvis of a pregnant woman; it is performed when there is doubt that the head
of the fetus can safely pass through the pelvis during the labor process.
Measurements are actually made on the x-ray, and the true dimensions of the birth
canal and the head of the fetus can be calculated to determine if the proportions are
suitable.
pregnancy testing: tests performed on maternal urine and/or blood to determine the presence of
the hormone, HCG (human chorionic gonadotropin); HCG is detected shortly after
the first missed menstrual period.
Tests performed on blood are highly reliable and results are usually available in
approximately one hour. Tests performed on urine are fairly accurate when done
correctly, and are very popular in the form of home testing kits; results are
available within minutes. Women using home testing kits should test the first
voided urine specimen of the day, since the level of HCG is highest at that time.
