The Cochrane Review concluded that indomethacin administration was associated with a significant reduction in births before the 37th week, as well as with increased gestational age at birth and increased birth weight, but it noted that there were insufficient data to determine fetal safety. Biochemical markers have been found to be useful in modifying the risk for stillbirth. Severe constriction with progressive arterial compromise, flow measurements distal and proximal of the constriction band a. Its only value in this setting is to guide Rh immune globulin dosing in Rh-negative women who are thought to have sustained an abruption. Prior preterm birth of twins confers an increased risk for preterm birth in a subsequent singleton pregnancy that is related to the gestational age at delivery of the index twin pregnancy,143,155,156 most recently in a study of 1957 women in the Netherlands Perinatal Registry with a twin birth followed by a subsequent singleton pregnancy. The double capillaries then become a single capillary with a loss of mesenchyme to form a new, thin, alveolar capillary membrane. Nociception requires an intact sensory system, and an emotional reaction requires some form of consciousness. During diastole, the common atrioventricular valve is open, and the large atrial and ventricular defects(in continuity)arereadily apparent. Progesterone supplementation for women at risk for preterm birth was investigated with regard to several plausible mechanisms of action, including reduced gap junction formation and oxytocin antagonism leading to relaxation of smooth muscle, maintenance of cervical integrity, and anti-inflammatory effects. The right ventricle should appear more heavily trabeculated and should extend toward the cardiac apex along with the left ventricle. Rodesch G, Hui F, Alvarez H, et al: Prognosis of antenatally diagnosed vein of Galen aneurysmal malformations, Childs Nerv Syst 10:79, 1994. Morken N-H, Kallen K, Jacobsson B: Fetal growth and onset of delivery: a nationwide population-based study of preterm infants, Am J Obstet Gynecol 195:154, 2006. For example, confined placental mosaicism for chromosome 16 leads to severe intrauterine growth restriction, prematurity, or perinatal death, with less than 30% of pregnancies resulting in normal, appropriate-for-gestational-age, full-term infants. More recently, in a study of 440 cases of acute antepartum pyelonephritis, Hill and coworkers143 reported that women with respiratory insufficiency received more intravenous fluids during the first 48 hours and had higher maximum temperatures, higher heart rates, lower hematocrits, and higher rates of septicemia. Use of progesterone for indications other than prior preterm birth and short cervix is not supported 40 Preterm Labor and Birth 651 by the limited available evidence. In addition, RhD sensitization would limit the availability of blood products if the patient later required a transfusion. Oxytocin stimulates contractions in labor at term by inducing conversion of phosphatidylinositol to inositol triphosphate, which binds to a protein in the sarcoplasmic reticulum, causing release of calcium into the cytoplasm. To understand what causes this change in the effectiveness of placental oxygen transport, we must turn our attention to the histology of human placental development. Hemoglobin electrophoresis shows hemoglobin E at approximately 40%, hemoglobin A at 1% to 30%, and a significant increase in hemoglobin F (at approximately 30% to 50%). Population-based strategies include prevention of unplanned and potentially unwanted pregnancies because both are associated with increased rates of preterm birth. This trial called into question the value of fetal pulse oximetry in helping patients forego abdominal delivery or improving the health of newborns. If infection occurs at this time, there is no opportunity for protective antibody to cross the placenta. Fetal red blood cells are considerably larger than those of an adult, but the value is gestational-age dependent. A lower threshold of exposure, below which no effects will be seen, has not been defined. Assessment of Normal Fetal Physiology Fetal assessment assumes that a change in fetal behavior implies a change in fetal status. The experimental evidence available is not consistent enough to confirm or to contradict either hypothesis. However, because delivery is very unlikely to cause massive hemorrhage by itself and fetal cells persist for up to 2 to 3 weeks after delivery, testing soon after delivery is reasonable.

Syndromes

• Loud noises or sounds, or loud sounds that last for a long time
• May make brief journeys away from parents to explore in familiar settings
• Axillary nerve dysfunction
• Pollen
• Redness around the surgery site
• The health care provider will shave and clean the groin area over an artery. A numbing medicine (anesthetic) is injected into the skin over an artery and a needle is inserted into an artery.
• Loss of sexual function (male impotence)

Sundberg K, Bang J, Smidt-Jensen S, et al: Randomised study of risk of fetal loss related to early amniocentesis versus chorionic villus sampling, Lancet 350:697, 1997. The adverse perinatal outcome associated with breech second twins is more often related to prematurity or growth restriction than to mode of delivery. Because of the relationships between refractory preterm labor and subclinical infection, and between subclinical infection and major neonatal morbidity,45-47 it is uncertain whether the association between indomethacin and adverse neonatal outcome in these retrospective observational studies is a true association or a spurious association resulting from confounding. Detailed case analyses of maternal mortality can drive advancement in obstetric care and improvements in maternity outcomes. Preterm surfactant-deficient rabbit lungs do not inflate until pressures exceed 25 cm H2O. Arbitrary limits on the duration of the second stage of labor probably resulted from misinterpretation of the data presented by Hellman and Prystowsky. Renal failure with a marked rise in serum creatinine concentration by 1 mg/dL over baseline or urine output less than 0. If a young woman with untreated tetralogy of Fallot requests pre-pregnancy counseling, she should be advised to undergo surgical correction before pregnancy. If this second dose is not administered in childhood, it should be administered before a woman plans her first pregnancy. During the last trimester of gestation, there is a progressive increase in maximal pressor response to ephedrine, which exerts its effect indirectly through neurotransmitter release; phenylephrine has a direct pressor effect. After delivery, all patients require close clinical and echocardiographic evaluation, as well as evaluation for DiGeorge syndrome. Over time, these failures are not recognized as unexpected deviations but rather become routine and normal. Fetuses with trisomy appear to have an increased incidence of tricuspid regurgitation, even in the presence of a structurally normal heart. Tocolytic therapy has not been studied when antenatal corticosteroids and antibiotics were administered concurrently, and it remains plausible that prophylactic tocolysis could delay delivery long enough to allow antibiotic suppression of subclinical decidual infection and for corticosteroid effects on the fetus. The highly saturated umbilical venous return streams preferentially across the foramen ovale into the left atrium, where it mixes with the relatively small amount of desaturated blood returning from the pulmonary veins. Because soft markers may be present even though the adjusted risk for trisomy 21 remains low, centers should develop policies on when to notify patients and offer invasive testing. In independent sequential testing, a first-trimester combined risk is calculated with a 1/270 screen-positive cutoff. Vibhakar N, Budorick N, Scioscia A, et al: Prevalence of aneuploidy with a cardiac intraventricular echogenic focus in an at-risk patient population, J Ultrasound Med 18:265, 1999. After the diagnosis of preeclampsia is made, it is even more important to monitor fetal well-being. Because cholesterol is a precursor of estriol, the defect results in reduced or undetectable levels of estriol in maternal serum and amniotic fluid. Occupational and environmental exposures to lead that precede pregnancy may result in fetal exposure due to mobilization of lead stored in maternal bone. Prolonged Latent Phase On the basis of the 95th percentile limit of the distribution of latent-phase duration in the primiparous population, 20 hours is considered the definition of an abnormal latent phase. Usual laboratory indicators of infection, such as positive stains for organisms or leukocytes and positive cultures, are found much more frequently than is clinically evident infection. The primary impact on perinatal mortality rate, however, comes from improvements in neonatal care. These changes are caused by the effects of progesterone on muscle tone and peristalsis and, more importantly, by mechanical obstruction of the enlarging uterus. Additional sonographic abnormalities may include cardiovascular, intracranial, renal, and placental malformations; intrauterine growth restriction; oligohydramnios; hydrops fetalis; and fetal anemia. The appropriate role for antimicrobial therapy to reduce the risk for preterm birth cannot be determined until questions about the roles of concurrent exposures.

Sharland G, Chita S, Allan L: Tricuspid valve dysplasia or displacement in intrauterine life, J Am Coll Cardiol 17:944, 1991. Patients are usually cyanotic and often have significant clubbing of the fingers and toes. Management of Pregnancy As noted earlier, the first clinical challenge for the obstetrician is to distinguish between the constitutionally small but otherwise normal fetus and the one with growth restriction. In addition, acute pyelonephritis in pregnancy can cause significant maternal morbidity and, in rare instances, maternal and fetal mortality. Occasionally, a patient complains of mild bladder dysfunction and buttock pain in the immediate postoperative period, but these symptoms are transient. Progress of labor was as rapid in the eight patients who were randomized to an ambulation study protocol as in six control patients whose labors were augmented with oxytocin. This no-blame culture has been questioned with the introduction of the concept of a just culture. Not only is the condition emotionally devastating for affected patients and their partners but also clinicians can be easily frustrated by a lack of sound clinical data to guide evaluation and management. A number of antimicrobial regimens may be used to treat acute pyelonephritis in pregnancy (Table 51-4). Yerushalmy J: Relation of birth weight, gestational age, and the rate of intrauterine growth to perinatal mortality, Clin Obstet Gynecol 13:107, 1970. Conventional 2D imaging is sometimes limited by interobserver and intraobserver variation in image interpretation. Cervical length is measured along the line made by the interface of the mucosal surfaces (the closed portion of the cervix). Similarly, Menticoglou and associates56 confirmed that the duration of the second stage of labor is in itself not related to untoward outcomes. One study showed that the perinatal mortality rate tripled for women with proteinuria,65 and another revealed a relationship between the amount of proteinuria and the perinatal mortality rate and number of growth-restricted infants. This category system is frequently misunderstood by health care providers and patients, and it is being replaced by a system that relies on plain text to give information about medications. Nelson T, Pretorius D, Sklansky M, et al: Threedimensional echocardiographic evaluation of fetal heart anatomy and function: acquisition, analysis and display, J Ultrasound Med 15:1, 1996. Perhaps the most readily preventable risk factor for abruption is cigarette smoking. Transverse fundalviewwithcolorDoppler shows a large posterior placenta, small anterior lobe, and connecting vesselscrossingbetween(Video27-4). The numerator is the number of subjects with the disease who have a positive test, and the denominator is the total number of those with a positive test. If she develops measles despite immunoprophylaxis, she should be observed for evidence of serious complications such as otitis media, hepatitis, encephalitis, and pneumonia. Pyrimethamine is not recommended during the first trimester of pregnancy because of possible teratogenicity. Women with a placenta previa and more than one prior cesarean should deliver in a center with a large blood bank and surgical support for a rapid cesarean hysterectomy. Thorp and Breedlove374 reviewed the benefits and risks of epidural analgesia for labor and delivery. The right atrium and ventricle commonly appear larger than expected (right heart disproportion), probably related to redistribution of flow to the right side of the heart, and color flow imaging may detect some degree of tricuspid regurgitation. Surgeon General has recommended that the safest course is to avoid ethanol entirely during pregnancy. Regardless of the method of delivery, the patient should receive intravenous zidovudine during delivery (2 mg/kg for 1 hour, then 1 mg/kg/hr until delivery). Fetal ventricular tachycardia usually manifests with fetal rates between 180 and 300 beats/ min and, often, poor ventricular function.

Cervical length by ultrasound, although far from an ideal test, had the best performance, as the uppermost line of the curves displayed. Nevertheless, a clinical dilemma occurs in differentiating a "benign" febrile response to the epidural from intra-amniotic infection. Although maternal and fetal risks rise with increasing blood pressure,60 serious complications can occur in women who experience only modest blood pressure elevations. If a reactive fetal heart rate tracing becomes abnormal, it should be interpreted as a sign of acute decompensation. Haimov-Kochman R, Sciaky-Tamir Y, Yancii N, et al: Conservative management of two ectopic pregnancies implanted in previous uterine scars, Ultrasound Obstet Gynecol 19:616, 2002. The characteristic findings include an ejection systolic murmur that is harsher and longer and peaks later than the normal ejection murmur of pregnancy. Placental and fetal infections probably originate from either ascending or hematogenous spread. Digital examination can shorten latency between membrane rupture and delivery, and some studies have shown that such examinations introduce vaginal organisms into the cervical canal and increase the risk for infection. A possible exception is the pregnant woman with severe septic shock, for whom an aminoglycoside should be used to provide coverage against highly resistant gram-negative enterobacteria such as Pseudomonas aeruginosa, Enterobacter species, or Citrobacter species. In the near-term placenta (39 weeks), the villous tree is subdivided into stem, intermediate, and terminal villi. Preterm labor and delivery were significantly more common, infants with congenital syphilis had significantly lower birth weights, and 21% had intrauterine growth restriction. Infants with trisomy 21 or other syndromes may have anomalous lung development or may have abnormal fetal breathing patterns that contribute to pulmonary hypoplasia. Premaxillary mass (black arrow) is seen between the bilateralclefts(white arrows). In myelomeningocele, the spinal cord is bulging through the defect into the subarachnoid space. The best care path is uncertain, but nevertheless, consideration of cervical ultrasound surveillance has entered routine prenatal care, and with it, some form of prematurity prevention screening may become standard for all pregnancies. Most studies of maternal mortality categorize maternal deaths by the causal pathway, regardless of the final event that led to cessation of heart and lung function, so the latter may not appear on the death certificate. Nonetheless, through a series of local and systemic adaptations, most pregnant women are able to balance these paradoxical requirements and achieve uncomplicated pregnancies. Mothers who do not demonstrate an adequate response (fourfold decrease) of nontreponemal antibody titers despite appropriate penicillin treatment 7. The remaining 14% had other types of rearrangements including pericentric and paracentric inversions. This large series attests to the preferability and safety of regional anesthesia in contemporary obstetrics. Those infants without respiratory compromise need detailed echocardiographic and clinical evaluation to determine the appropriate timing for surgical intervention. Because most first pregnancies occur in young women, most cases of preeclampsia occur in this age group. Some laboratories use mutation analysis as their primary screening approach in the Ashkenazi population. If fibroids are noted in the lower uterine segment, ultrasound assessment of their size and location near term can aid in delivery planning. The incidence of iron deficiency as measured by total body iron, which takes into account body weight, was 18% in the first trimester and rose to 29% by the third trimester in U. Using an insonation angle of 90 degrees, both ends of the ossified femoral metaphysis should be visible.

Public awareness of the importance of preterm birth as a leading cause of infant mortality remains low. A maternal electrocardiogram and, ideally, consultation with an adult cardiologist is performed before therapy is initiated. In pregnancy, it is best to consider all seropositive women as infected unless an adequate treatment history is documented and sequential serologic antibody titers have declined. The remaining clinically indicated tests were positive in a much smaller proportion of stillbirths: anticardiolipin antibodies (4. Jauniaux E, Van Maldergem L, De Munter C, et al: Nonimmune hydrops fetalis associated with genetic abnormalities. Polyhydramnios is common and results from small bowel obstruction caused by compression by a large cyst. Cassin S: Role of prostaglandins, thromboxanes, and leukotrienes in the control of the pulmonary circulation in the fetus and newborn, Semin Perinatol 11:53, 1987. Mitotic errors occurring after primary cell differentiation and compartmentalization have been completed lead to cytogenetic abnormalities in only one lineage. In many cases, a fetus is identified as having structural malformations either by ultrasound or at a postnatal evaluation. Gestational age is the strongest pre-delivery predictor of survival and morbidity for the infant. Vaginal delivery is almost always appropriate in the absence of an obstetric indication for abdominal delivery. Where does the individual physician fit into a just culture that must balance no-blame and accountability Whereas restorative disciplinary measures are appropriate in cases of misconduct involving willful disregard for safety or standards, as James Reason points out, in the case of a slip, there is little benefit from simply putting "a carcass up on the wall" to show that something has been done. Given the importance of advancing gestational age on these long-term outcomes and particularly in the context of emerging information regarding the negative consequences of late preterm93,94 and early term birth,95 additional information is needed regarding the most appropriate thresholds for intervention before 39 weeks. The serum concentration of IgG rises more slowly, but antibody levels persist throughout the lifetime of the individual. Gonococcal ophthalmia is usually observed within 4 days after birth, but incubation periods of up to 21 days have been reported. New England Regional Genetics Group Prenatal Collaborative Study of Down Syndrome Screening: Combining maternal serum alphafetoprotein, human chorionic gonadotropin, and unconjugated estriol, Am J Obstet Gynecol 169:526, 1989. The higher oxygen consumption in fetal mitochondria uncoupled by deoxyribonucleoprotein suggests that the augmented respiratory rate in mitochondria is a reflection of increased electron transport. A simple catch-all term, congenital thoracic malformation, should replace the old nomenclature in clinical discussions. In such cases, a detailed evaluation for associated cardiac abnormalities, such as right heart obstruction in the case of excessive deviation, should be performed. Specific fetal information, including data from first- and second-trimester screening, biochemical testing, and growth 32 Assessment of Fetal Health 487. In the latter type of outbreak, approximately one third of the cases have occurred in individuals who were previously vaccinated. This suggests that the majority of women with a short cervix by sonography will not deliver prematurely. Magnesium should be administered cautiously in women with evidence of renal impairment, such as oliguria or serum creatinine levels higher than 0. One report showed elevation of neonatal blood pressure 2 standard deviations above the normal range in 67% of children exposed to multiple courses and 24% of those exposed to a single course.

The authors emphasized the need to prevent unnecessary primary cesarean deliveries and identified induction practice as an ideal place to start. If the diagnosis is made and reinversion is accomplished promptly, there are no long-term sequelae. Because of these findings, sonographic assessment of the fetus before initiation of therapy for early syphilis in the last half of pregnancy has been recommended. Hyett J, Moscoso G, Nicolaides K: Morphometric analysis of the great vessels in early fetal life, Hum Reprod 10:3045, 1995. Although mumps usually is a self-limited disease, it can cause aseptic meningitis, pancreatitis, mastitis, thyroiditis, myocarditis, nephritis, and arthritis. Interruption of anomalous conduction pathways also can be performed during surgery. Adab N, Kini V, Vinten J, et al: the longer-term outcome of children born to mothers with epilepsy, J Neurol Neurosurg Psychiatry 75:1575, 2004. Pinto A, Sorrentino R, Sorrentino P, et al: Endothelial-derived relaxing factor released by endothelial cells of human umbilical vessels and its impairment in pregnancy-induced hypertension, Am J Obstet Gynecol 164:507, 1991. Chronic hypertension is associated with a fivefold increase in risk, which rises to eightfold with superimposed preeclampsia. The echocardiographic findings are often diagnostic and include marked thickening of the ventricular septum, usually with less thickness of the other walls of the left ventricle (asymmetrical hypertrophy), and abnormal systolic anterior movement of the mitral valve. Signs are local edema and erythema with exudate; more extensive findings should raise the suspicion of a deeper infection. The decrease is gradual; the time from onset of deceleration to nadir is at least 30 seconds. In contrast, patients with pulmonary blood flow dependent on aortopulmonary collaterals usually have severely hypoplastic or absent true pulmonary arteries and face a much more guarded long-term prognosis. Such abnormalities can be caused by established chromosomal disorders or by dysmorphic syndromes, such as various forms of dwarfism. They include routine use of continuous fetal heart rate monitoring, routine initiation of antihypertensive therapy (which should be avoided except for women with chronic hypertension and those being managed according to standard protocols for severe preeclampsia by blood pressure criteria only remote from term),312 prolonged (>48 hours) antepartum administration of magnesium sulfate seizure prophylaxis, serial 24-hour urine collections for protein quantitation, and routine assessment of fetal lung maturity. In cases of suspected placental pathology, calculation of a pulsatility index enables a quantitative assessment of placental resistance. Despite the fact that preeclamptic patients are plasma volume depleted, the use of fluids is controversial because excessive fluid infusion can lead to congestive heart failure and perhaps cerebral edema. Dividing the measured result by the twin median can be used to estimate a twin MoM for each analyte. Despite the variable approaches, the results are similar: preventability varies with the cause. This is contrary to most other methods, which prescribe initial volume acquisition in the midsagittal plane. Patient tolerance of this technique may be a problem, as well as the potential requirement of two operators when sampling. Hydrops fetalis, a collection of fluid in at least two serous compartments, typically heralds end-stage disease, and it occurs with hemoglobin deficits of 7 g/dL or greater. When the tissue appears healthy (usually after about 1 week or longer), a definitive repair can be undertaken. Recombinant erythropoietin has been attempted in these infants with minimal effect on their reticulocytosis. The diagnosis required visualization of intraluminal filling defects observed on two or more views, or an abrupt cutoff of contrast material. The role of -adrenergic stimulation in resting circulatory regulation has been evaluated by pharmacologic blockade of -adrenergic receptors with propranolol. Gonorrhea incidence among blacks decreased considerably during the 1990s, but blacks continue to have the highest rate among all races/ethnicities. These theoretical considerations agree with the experimental evidence that umbilical Po2 does not equilibrate with maternal Po2 if the fetus is removed by cesarean section and the umbilical circulation is perfused by means of a pump. Previous births before 17 weeks did not confer an increased risk for recurrent preterm delivery. Clinical examination usually shows erythema, induration, and tenderness at the margins of the abdominal incision, and pus exudes from within the incision.

This component of the sympathetic nervous system exerts a positive influence over fetal heart rate that first appears at about 0. In contrast, benign echogenic reflectors or foci reside exclusively in the chordal apparatus of the mitral or tricuspid valves and do not extend into the ventricular myocardium. Antibiotic treatment increased the likelihood of continued pregnancy after 7 days of treatment by twofold. The preferential streaming of umbilical venous return to the left lobe of the liver and portal venous return to the right lobe also affects the distribution of oxygenated blood to the fetal body. Discharged patients are typically readmitted to the hospital after the limit of viability has been reached to allow early intervention for infection, placental abruption, labor, and non-reassuring fetal heart rate patterns. If the ligament is directed laterally and the spines are far apart, the posterior segment of the inlet is likely to be flat. Sacral agenesis results in significant orthopedic disability (similar to paraplegia). Valvar aortic stenosis (see Video 23-7), usually secondary to a thickened, bicommissural aortic valve, is one of the most common lesions known to have the potential to evolve dramatically during the second and third trimesters. As with vagal tone, tonic sympathetic influence increases as much as twofold during fetal hypoxia. In tricuspid atresia, the tricuspid valve either is not formed or simply does not open. The volume-rendered images can then be rotated along the vertical axis, improving identification of anomalies. An abnormally shaped cephalic contour may suggest this diagnosis earlier in gestation. In Fuchs A, Fuchs F, Stubblefield P, editors: Preterm birth: causes, prevention, and management, New York, 1993, McGraw-Hill. These recommendations of Rouse and colleagues11 raise the issue of whether intrauterine pressure catheters are useful tools for clinicians managing labor abnormalities. Isolated unilateral renal agenesis is most often found as an incidental finding, with normal life expectancy. A likelihood ratio is defined as the probability of the test result in the presence of outcome, divided by the probability of the result in those without the outcome. Rizzo G, Arduini D, Romanini C: Uterine artery Doppler velocity waveforms in twin pregnancies, Obstet Gynecol 82:978, 1993. Fetal sex may play a significant role in the fetal response to maternal antibodies. The 5-year mortality rate among patients with spina bifida undergoing neonatal repair is 79 per 1000 births.

This unique study design reduces potential selection bias of controls coming from a population that is different from that of the cases. Complicated Atrial Septal Defect If atrial arrhythmias recur frequently-and especially if the heart rate is difficult to control-catheter ablation may be successful in restoring normal sinus rhythm without the need for antiarrhythmic drugs. Serial ultrasound examinations to monitor fetal growth, amniotic fluid, and worsening fetal condition Fetal nonstress or biophysical profile testing (or both), twice weekly, beginning at 32-34 weeks Fetoscopic in utero treatment reduces need for cerebral ventricular shunt placement by 50% and improves motor function, but it increases preterm delivery compared with conventional postnatal treatment (80% versus 15%). Low birth weight, but not preterm birth, was significantly higher in infants born after fresh, compared with frozen and thawed, embryo transfer. Achondroplasia, the most common form of dwarfism, may not become apparent until measured in the third trimester. In 1997, B-Lynch and colleagues118 described a "brace" suturing technique that results in closure of the uterine blood supply. Management includes early diagnosis and fetal monitoring, with retraction of the presenting extremity and normal vaginal delivery occurring in most cases. Tissues should be placed in a sterile tissue culture medium of lactated Ringer solution at room temperature. After all signs of infection have resolved and healthy granulation tissue is apparent, a secondary closure may be considered.

There are now many case reports and series of pregnancy-associated aplastic anemia, although they present a spectrum of clinical and bone marrow findings that makes it difficult to substantiate the existence of an aplastic anemia specifically related to pregnancy. The most common pathway by which microorganisms gain access to the choriodecidua and amniotic cavity is probably ascent from the vagina and the cervix, but the timing of this spread is uncertain. In some categories, risks may be significantly different if the premutation is carried by a woman with a family history of fragile X syndrome. The record above the aortic pressure tracing is a phonocardiogram showing the systolic murmur. The numerator is the number of subjects without disease who have a negative test, and the denominator is the total number of those with negative tests. Though long-term follow-up is not yet available, it is reasonable to hope for a durable outcome, as was earlier demonstrated in observational studies. In this plane, the fetal profile, including the frontal bone, is evaluated and the nasal bone length is measured. Retraction of the fetal head immediately on its delivery (turtle sign) is an early warning that delivery of the shoulders may be difficult. Now, almost three times as many women giving birth are older than 35, and this group contains about 50% of trisomy 21 conceptions. In a retrospective study that controlled for gestational age and other factors, two or more courses of antenatal corticosteroids were associated with increased early neonatal sepsis (15. They measured the pulsatility index, peak early-diastolic reversed flow, and peak systolic velocity in the proximal branches (first intrapulmonary branch of the main pulmonary artery) of the contralateral lung, as well as the "fractional moving blood volume," which is a measure of lung tissue perfusion. Hepatic arterial blood flow to the liver is equally distributed to the right and left lobes, but the left lobe is supplied almost exclusively (>95%) by umbilical venous blood. As with red cell alloimmunization, the condition tends to worsen throughout pregnancy and in subsequent pregnancies. In fetal sheep, the adverse effects of maternal corticosteroids reverse with further fetal development, but prolonged and high-dosage fetal exposures could affect lung outcomes. The uterus is closed in two layers with prior restoration of amniotic fluid and antibiotic administration and covered with an omental patch. This has been demonstrated in countless case reports by the diagnosis of structural changes at the submicroscopic level. Celiac disease is also known to affect other target organs, including the liver, thyroid, skin, and reproductive tract. The phenotype of full mutation females, although also dependent on the size of the mutation, can be modified by random inactivation of either the normal or the mutated X chromosome in the brain. Therefore, in the vitamin study (see Table 16-2), the relative risk was as follows: Relative risk = 56/935 0. On the other hand, hypothyroidism, both overt and subclinical, is relatively common, occurring in about 2. Occasionally, particularly when dilated, the coronary sinus (seen longitudinally) may generate the appearance of an absent inferior portion of the atrial septum. With repositioning of the patient, it is important to reestablish accurate monitoring of the fetal heart and uterine activity. Recently, Ljungan virus, a picornavirus of bank voles, originally isolated in Sweden, has been reported to cause stillbirth in both Denmark and the United States. The transplacental passage of fetal erythrocytes in homospecific pregnancies, Blood 23:621, 1964. Small defects in the muscular ventricular septum frequently close spontaneously during childhood. Platelet transfusions should be considered only as a temporary measure to control life-threatening hemorrhage or to prepare a patient for cesarean delivery or other surgery. Placental development had compensated for the lower uterine venous Po2 of the A sheep by producing a smaller uterine-umbilical venous Po2 difference (14. Although there may be a reduced incidence of respiratory distress syndrome in neonates born to preeclamptic women, this does not justify withholding antenatal corticosteroid therapy. Choosing only whole, clearly typical villus material and discarding any atypical fragments, small pieces, or fragments with adherent decidua avoids confusion.

Provision of long-acting reversible contraception among women at risk for unplanned pregnancy was successful in reducing unplanned births in a community program in St. These late decelerations were probably vagal reflex types caused by chemoreceptor activity. The left ventricle does not dilate until the ventricle fails, so a dilated ventricle in aortic stenosis is an ominous sign that calls for rapid intervention. If labor progresses and there is evidence of resolution of a brow presentation to either a face or a vertex presentation, labor should be managed with the expectation of vaginal delivery. A 24-hour urine specimen is preferable for diagnosis because of the discrepancy between random protein determinations and 24-hour urine protein measurements in preeclampsia. Membrane rupture after amniocentesis is associated with cessation of leakage and subsequent successful pregnancy outcomes in most cases. In addition, the risks to maternal health of expectantly managed higher-order multiple gestations are significant. Because of potential repeat instability with transmission of premutation alleles through maternal meiosis, women with alleles in this range are considered to be at risk for having children affected with fragile X syndrome and should consider prenatal diagnosis. The exponential growth of these villi occurs at a stage when fetal oxygen demand is increasing exponentially, requiring the placenta to become more effective in transporting oxygen from the uterine to the umbilical circulation. Maternal risks of hemoglobin Barts hydrops fetalis syndrome include preeclampsia and postpartum hemorrhage. Jouppila and colleagues,309 however, found that epidural anesthesia was associated with a decreased clearance of xenon 133 (presumed to reflect decreased uteroplacental perfusion), especially when hypotension occurred. First, adult mammals of similar body size, such as sheep and humans, have similar basal oxygen consumption rates despite major differences in body composition. Sacrococcygeal teratomas are large vascular tumors that act as arteriovenous shunts and may be associated with hydrops on this basis. Each case must be individualized based on gestational age and the previous antenatal test findings, combined with clinical judgment. The fetal head is imaged in a transverse plane, the plane used to measure the biparietal diameter. Ruma and colleagues48 used immunomodulation in a series of nine patients, seven of whom had experienced a previous perinatal loss. Pillai M, James D: Development of human fetal behavior: a review, Fetal Diagn Ther 5:15, 1990. Their levels are similar to those of Tay-Sachs carriers, leading to a potentially incorrect determination of a carrier. It is present in about 5% of Europeanderived populations and 3% of African Americans, but it is very rare in nonwhite Africans and Asians. Other possible abnormalities include microcephaly, mental retardation, pneumonia, fetal growth restriction, hepatosplenomegaly, hemolytic anemia, and thrombocytopenia. Although the pulsation pattern has been suggested as a discriminator,80 other investigators have not been able to duplicate this correlation. Early surgical treatment may reduce the risk of brain compression, with improved neurodevelopmental outcome. Therapy is reserved for women in whom blood pressure is persistently higher than 160 systolic mm Hg or higher than 105 to 110 mm Hg diastolic, the levels associated with intracranial bleeding and stroke, for more than 15 minutes. Single gene disorders Copy number variants Single nucleotide polymorphisms Cytokine genes Angiogenic factor genes Hormone receptor genes Male genetic factors the group with no history of aneuploidy, supporting a theory of diminished ovarian reserve. Szabo J, Gellen J: Nuchal fluid accumulation in trisomy-21 detected by vaginosonography in first trimester, Lancet 336:1133, 1990. Other anomalies included heart, diaphragmatic hernia, omphalocele, and limb reduction.

In addition, the risk for very premature delivery at 25 to 28 weeks decreased from 6% to 6%, 4%, 3%, and 1%, respectively. Even in culture, the contaminating cells are easily identified as maternal and should not lead to clinical errors. Another way of looking at these same data would be to look closely at the low prevalence of delivery within 7 days (3%). However, proper diagnosis is important for counseling and prenatal diagnosis in future pregnancies. Since licensure of the first measles vaccine in 1963, the incidence of infection has decreased by almost 99%. Complete or partial heart block in the fetus produces variations in rate that are markedly slower than normal. Selection of mode of delivery depends on (1) the size of the second twin, (2) the presence of growth discordance (estimated weight of second twin at least 25% greater than first twin), and (3) the availability of obstetric staff skilled in assisted breech delivery, internal podalic version, and total breech extraction. Delivery at or near term is always preferable and is indicated if fetal growth has continued to be adequate and antenatal testing results have been normal. This approach necessarily raises some ethical questions, especially because prediction of the extent of neonatal impairment on antenatal imaging 35 Invasive Fetal Therapy 531 may be insufficiently accurate. Fetal growth restriction is possible if placental implantation is on one or more fibroids. Other than the recommendations of Rouse and colleagues12,14 to prolong augmentation in the face of second-stage arrest, we know of no new clinical guidelines for obstetricians to use. Tabor A, Philip J, Bang J, et al: Needle size and risk of miscarriage after amniocentesis, Lancet 1:183, 1988. Low-dosage aspirin should be used as an adjunct to warfarin, based on a study of antithrombotic therapy in high-risk patients with mechanical valves. Perusal of these tables shows that a parity 0 woman may require up to 4 hours to progress from 4 to 5 cm dilation. The low transverse incision often suffices in cases of a back-up transverse lie, and the high transverse incision described by Durfee219 can be used in cases of a back-down shoulder presentation. More severe forms of coarctation of the aorta manifest as ductal-dependent lesions requiring initiation of prostaglandin after delivery to maintain systemic cardiac output. It should detect fetal peril with specificity, sensitivity, and timeliness to allow preventive intervention. Kaplan C: Alloimmune thrombocytopenia of the fetus and the newborn, Blood Rev 16:69, 2002. Men who have fathered preeclamptic pregnancies are more likely to father preeclamptic pregnancies with new partners than are men who have never been fathers in preeclamptic pregnancies. Kronn D, Oddoux C, Phillips J, et al: Prevalence of Canavan disease heterozygotes in the New York metropolitan Ashkenazi Jewish population, Am J Hum Genet 57:1250, 1995. Either amoxicillin or azithromycin is recommended as treatment for presumed concomitant chlamydial infection during pregnancy. Small bowel transplantation may be necessary, with a 5-year patient survival rate of 55%; the survival rate after grafting is 45%. Disturbances of Cardiac Rhythm Isolated supraventricular and ventricular extrasystoles are very common, and no treatment is necessary. Hemostatic System the hemostatic system is designed to ensure that hemorrhage is avoided in the setting of vascular injury while the fluidity of blood is maintained in the intact circulation.
