A prospective, randomized comparison of Foley catheter insertion versus intracervical prostaglandin E2 gel for preinduction cervical ripening.

OBJECTIVE: The objective of this study was to compare intracervical prostaglandin E2 gel with insertion of a Foley bulb for efficacy in preinduction cervical ripening. STUDY DESIGN: Women who came to the hospital for induction of labor with a Bishop score </=5 were randomly assigned to treatment with either prostaglandin E2 gel or a Foley bulb. Prostaglandin E2 gel was used according to the manufacturer's recommendation. The Foley group had a number 14 Foley catheter inserted, inflated, and placed on traction. Immediately after Foley bulb extrusion or 6 hours after prostaglandin E2 gel course completion, a dilute oxytocin solution was started if the patient was not in labor. RESULTS: Seventy-seven women were entered into the Foley group and 72 were entered into the prostaglandin E2 gel group. Both the Bishop score after preinduction ripening (6.5 vs 5.1, P <.001) and the change in Bishop score (3.5 vs 2.7, P =.015) were significantly higher in the Foley group. There were no differences between the groups in mode of delivery, infant weight, rate of hyperstimulation, shoulder dystocia, patient discomfort, epidural use, oxytocin use, or nonreassuring fetal heart rate patterns. The preinduction time (9.9 vs 17.2 hours, P <.001) and the total induction time (22.4 vs 30.4 hours, P <.001) were significantly shorter in the Foley group. Patient charges were 31% lower in the Foley group (P <.001). CONCLUSION: Use of the Foley catheter resulted in a higher postinduction Bishop score, a greater change in Bishop score, a shorter induction time, and lower patient charges than did intracervical prostaglandin E2 gel.

Factors affecting fellowship satisfaction, thesis completion, and career direction among maternal-fetal medicine fellows.

OBJECTIVE: To determine fellowship satisfaction through a survey of maternal-fetal medicine fellows. METHODS: We constructed a survey using multiple choice, Likert scale, ordinal, and categorical scale questions. The questions focused on faculty involvement, mentorship, research time and productivity, education, fellowship selection, ultimate goals of fellows, and satisfaction. We sent the survey in two mailings to all maternal-fetal medicine fellows during April and May 1996. RESULTS: One hundred thirty-eight surveys were mailed, and 136 were returned (98.5% return rate). Twenty-seven percent of fellows did not believe they would complete their thesis by the end of their fellowship. No statistically significant relationship was noted between the fellows' predicted thesis completion and the availability of funding, support for statistical analysis, the presence of animal research facilities, age, number of dependents, or year of fellowship. The presence of a mentor on the maternal-fetal medicine faculty increased the likelihood of thesis completion from 52.3% to 83.5% (P < .001). Similarly, the presence of a faculty advisor increased the likelihood of thesis completion from 58.9% to 83.5% (P = .001). Thirty-two percent of the respondents did not have a mentor on the faculty, and 41% did not have a faculty advisor. Forty percent indicated that they were too involved in clinical pursuits to perform research. This group was significantly more likely to believe that their theses would not be completed (63% versus 80%, P = .029). Overall, 22% of the fellows would not recommend their fellowships. Fellows with a mentor (88.2% versus 55.8%; P < .001) or faculty advisor (87.3% versus 64.9%; P = .002) were more likely than those without to recommend their fellowship. CONCLUSION: A mentor or faculty advisor plays a significant role in the training of maternal-fetal medicine fellows and is associated with a higher incidence of satisfaction with the fellowship program, thesis completion, and entrance into academic practice.

Tocolysis of preterm contractions does not improve preterm delivery rate or perinatal outcomes.

To determine whether hospital admission and parenteral tocolysis of patients with threatened preterm labor results in a decreased preterm delivery rate and improved perinatal outcome, we performed a prospective cohort study comparing tocolytic treatment versus no tocolytic treatment. Women between 20 and 37 weeks' gestation who presented with at least eight uterine contractions per hour and a cervical examination <2 cm dilated, <80% effaced, and no cervical change over a 2-hr period were entered into the study. Exclusion criteria included cervical change, multiple gestation, chorioamnionitis, rupture of membranes, placenta previa or abruption, undiagnosed vaginal bleeding, and prior tocolytic therapy in the current pregnancy. Seventy-five patients were admitted to the hospital for tocolysis (tocolysis cohort) and 81 were observed and discharged to home (observation cohort). There was no significant difference in mean gestational age at delivery, mean birth weight, or in preterm delivery rate between the two cohorts. Four of the eight women in the observation cohort who delivered preterm had a history of preterm delivery. We conclude that discharging women with preterm contractions without objective evidence of labor does not result in an increase in preterm births. More importantly, tocolysis did not decrease the preterm delivery rate in this cohort.

Increase in ambient temperature may explain decrease in amniotic fluid index.

In the third trimester, the amniotic fluid index (AFI) may be affected by maternal fluid status. As the ambient temperature increases, there is an increase in insensible fluid loss and the potential for dehydration. We hypothesize that as temperature increases there would be a concomitant decrease in AFI. From June 11 to August 16, 1993, during a period of unusual high heat, 42 women with singleton pregnancies between 27 and 40 weeks' gestation undergoing serial antenatal testing had AFI determinations recorded at least weekly. The daily high ambient temperature in our urban area was subsequently obtained. A 2-, 3-, and 4-day mean temperature prior to the test date was compared to AFI using a Spearman-rank Correlation. The daily high temperature ranged from 71 to 104 degrees F and AFI values ranged from 1.7 to 24.7 cm during the study period. There was a significant correlation between the 2-, 3-, and 4-day mean temperature and AFI, with the 4-day mean being the most significant (r = 0.31, p < 0.001). Fluctuations in ambient temperature are inversely correlated to changes in AFI. This relationship should be taken into account when interpreting the AFI as a measure of fetal well-being.

An analysis of neonatal morbidity and mortality in maternal (in utero) and neonatal transports at 24-34 weeks' gestation.

Sophisticated neonatal transport has improved the safety of transporting preterm infants, but may not substitute for the benefits of in utero transport. To describe gestational age trends and assess differences in complications between maternal (in utero) and neonatal transports, we analyzed maternal and neonatal transports, over 3 years, to the only tertiary center in the region. Those who delivered between 24 and 34 weeks' gestation were included in the analysis. Gestational age trends for each complication are described, showing, in general, decreasing morbidity with gestational age in both groups. These trends were usually parallel, but not equal. A significantly greater mean neonatal intensive care unit (p = 0.003) and total length of stay (p = 0.006) as well as longer ventilator time (p = 0.01) and oxygen therapy exposure (p = 0.018) were noted in those transported neonatally. The incidence of respiratory distress syndrome (p < 0.001), bronchopulmonary dysplasia (p = 0.027), intraventricular hemorrhage (p = 0.041), intraventricular hemorrhage grades III and IV (p = 0.008), patent ductus arteriosus (p = 0.032), and mortality (p = 0.001) were all significantly greater among the neonatal transports. The differences were not significant for retinopathy of prematurity, hyperbilirubinemia, necrotizing enterocolitis, periventricular leukomalacia, and culture proven sepsis. Specialized neonatal transport and advanced neonatology techniques have not removed the significant advantage of decreased morbidity, mortality, and length of hospital intervention resulting from maternal (in utero) transport.

Indicators of platelet turnover in thrombocytopenic infants.

Glycocalicin has been found to be a marker of increased platelet turnover, while interleukin-6 may be increased in response to thrombocytopenia. We used these markers to study the pathophysiology of thrombocytopenia in newborn infants. Cord blood platelet counts were obtained from 499 infants. Thrombocytopenic infants (< 100,000/mm3) and a control group had ELISA assays for interleukin-6 and glycocalicin performed. The mean levels of glycocalicin and interleukin-6 were elevated in cord blood of thrombocytopaenic infants. Infants with intrauterine growth restriction and thrombocytopaenia had no detectable glycocalicin in their plasma, despite elevated levels of interleukin-6. This probably reflects impaired thrombopoiesis in these infants.

Adjustment of birth weight standards for maternal and infant characteristics improves the prediction of outcome in the small-for-gestational-age infant.

OBJECTIVE: Birth weight is a function of gestational age. Various maternal and infant characteristics also affect birth weight. This study sought to adjust for these factors to better define abnormal growth. STUDY DESIGN: Maternal and infant characteristics from normal pregnancies were correlated with birth weight. A formula was developed and applied to a second group in which we compared perinatal outcomes in normally grown infants with those who were small for gestational age. We compared outcomes between small-for-gestational-age infants defined by the formula with those defined by conventional tables. RESULTS: Infants defined by the formula as small-for-gestational-age were more likely to have morbidity and mortality than those who were normally grown (p < 0.001). Small-for-gestational-age infants defined by the formula had more deaths and adverse outcomes than those defined by gestational age. CONCLUSION: Adjusting birth weight standards for maternal and infant characteristics may improve the prediction of adverse outcomes.

Surgery for pancreatic tumors during pregnancy: a case report and review of the literature.

Seven cases of surgery of pancreatic tumors during pregnancy have been reported in the literature. Six of the cases resulted in live term births. The patient discussed herein, a 37-year-old para 2-0-0-2 white female, had surgery for the removal of a pancreatic mass at 20 2/7 weeks' gestation. No intraoperative complications occurred, and both mother and fetus appeared to have done well. The postoperative course was complicated by pseudomembranous enterocolitis caused by C. difficile, which was treated with antibiotics. Despite treatment, diarrhea continued, and the patient was readmitted to the hospital for hydration and further antibiotics at 27 weeks. Three days after admission, the fetus was noted to have poor biophysical testing and a caesarean delivery was performed. The infant was found to have a large intracerebral hemorrhage, which most likely occurred antenatally, and life support was discontinued shortly after birth. We conclude from this that surgery for a pancreatic mass in pregnancy should be approached cautiously, and the risk to both the mother and fetus should be considered.

Molecular genotyping of fetal platelet antigens with uncultured amniocytes.

OBJECTIVE: Amino acid substitutions in platelet membrane glycoproteins result in alloantigens implicated in neonatal alloimmune thrombocytopenia. We report the use of the reverse dot blot technique to genotype the five major fetal platelet alloantigens from amniotic fluid cells. STUDY DESIGN: We evaluated a patient with Bakb platelet antibodies who had a previous pregnancy complicated by fetal intracranial hemorrhage. The father was heterozygous Baka/Bakb, giving the pregnancy a 50% risk for platelet incompatibility between mother and fetus. Amniotic fluid was obtained at 16 weeks. Deoxyribonuleic acid was extracted from uncultured amniocytes and amplified with polymerase chain reaction. These products were hybridized to filters containing oligonucleotides specific for each of the 10 different platelet antigen alleles. Reactivity was detected with a chromogenic substrate. RESULTS: The reverse dot blot genotyping of uncultured amniocytes revealed the fetus to be Baka/Baka, thus not at risk for neonatal alloimmune thrombocytopenia. CONCLUSION: Precise knowledge of fetal platelet type by amniocentesis could obviate the need for fetal blood sampling and significantly alter prenatal management of neonatal alloimmune thrombocytopenia.

The use of polymerase chain reaction to determine fetal RhD status.

OBJECTIVE: Our purpose was (1) to establish the accuracy of a deoxyribonucleic acid amplification method in determination of RhD status in adult blood samples, including weak D variants (previously referred to as Du) and a D mosaic, and (2) to apply the method to determine fetal RhD status in alloimmunized pregnancies. STUDY DESIGN: Twenty-five adult blood samples, including five weak D variants and one D mosaic, were analyzed with a polymerase chain reaction to determine RhD type. The method was then applied to amniotic fluid samples obtained by amniocentesis from three RhD-negative women with known RhD sensitization. RESULTS: RhD type determined by polymerase chain reaction for all adult blood samples agreed with serologic typing results. All weak D variants and the D mosaic gave results consistent with RhD positivity. Fetal RhD status was determined in each of the three alloimmunized pregnancies, and obstetric management decisions were made on the basis of these results. CONCLUSIONS: This polymerase chain reaction method allows rapid and accurate determinations of fetal RhD status by amniocentesis. Fetal blood sampling or serial amniocenteses may be avoided when the fetus is RhD negative, and plans for surveillance and intervention can be confidently made if the fetus is RhD positive. However, before the widespread use of this assay, its sensitivity and specificity must be established. Because weak D variants and a D mosaic demonstrated RhD-positive status by polymerase chain reaction, the method described is applicable to these RhD variants.

Placental abruption following placement of disposable intrauterine pressure transducer system.

There have been few reported complications of intrauterine pressure monitoring. We present four cases of placental abruption following insertion of a disposable intrauterine pressure transducer system (INTRAN). All four patients had placental abruptions, which were evident soon after insertion of the disposable intrauterine pressure transducer system (all of our cases had predisposing factors or signs of placental abruption at presentation). Whether there was a preexisting placental abruption, which was caused, revealed, or worsened by insertion of the disposable intrauterine pressure transducer system is unclear. We encourage careful patient selection with gentle insertion of the system opposite the placental site.

Congenital heart disease in adolescents and adults. Pregnancy and contraception.

As the detection and treatment of congenital heart disease improves, more women are reaching childbearing age. The type of congenital heart disease, whether there has been corrective surgery, and the patient's functional status determines the maternal as well as fetal outcome. The patient may present to her physician for preconceptual counseling or late in her pregnancy with little care and in severe distress. These possible situations necessitate that the physician becomes familiar with congenital heart disease and its implications in the pregnant patient.
