Predictors of perinatal survival in a cohort of pregnancies with severe oligohydramnios due to premature rupture of membranes at <26 weeks managed with serial amnioinfusions.

OBJECTIVE: To evaluate whether successful amnioinfusion is an independent predictor of perinatal survival in a cohort of cases with extreme and persistent oligohydramnios due to preterm premature rupture of membranes (pPROM) who reached viability and were managed with serial amnioinfusions. STUDY DESIGN: We included all consecutive singleton pregnancies with pPROM at <26 weeks and oligohydramnios lasting >4 days between 1/1991 and 12/2001 and who consented to undergo amnioinfusion (n=77). Women received serial transabdominal amnioinfusions in an attempt to maintain a pocket of fluid >2 cm. The procedure was deemed successful if the median deepest pocket of fluid during the latency period was >2 cm. Excluded were miscarriages (n=10), fetal deaths before viability (24 weeks) (n=15), and cases that did not develop oligohydramnios (n=17). Prenatal predictors of outcome were compared between cases who survived the perinatal period and those who did not using Wilcoxon rank-sum test, Fisher's exact test and stepwise logistic regression analysis, with a two-tailed P<0.05 considered significant. RESULTS: Of the 35 patients fulfilling the study criteria, 20 (57%) survived the perinatal period. Perinatal survivors had similar gestational age at pPROM (P=0.68) and at first amnioinfusion (P=0.53) as those who died in the perinatal period, but longer latency (P=0.013). Consequently, median gestational age at delivery [29.2 (25.4-35.3) weeks versus 26.1 (24.0-34.0) weeks, P<0.001] and median birth weight [1220 (650-2240) g versus 863 (520-2200) g, P=0.001] were significantly greater among survivors than among those who died. Significant predictors of survival at univariate analysis were entered into a stepwise logistic regression analysis in the chronological order in which they normally occur. The analysis demonstrated that successful amnioinfusion (OR=6.9, 95% CI 1.2-40.4) and administration of steroids (OR=14.6, 95% CI 1.5-144.1) were independent and significant predictors of perinatal survival. CONCLUSION: In a cohort of women with pPROM at <26 weeks and severe oligohydramnios managed with serial amnioinfusions, successful procedures and prenatal administration of corticosteroids are the only independent predictors of perinatal survival.

Factors affecting survival in infants weighing 750 g or less.

OBJECTIVE: To assess which factors independently affect survival in infants weighing 750g or less. STUDY DESIGN: We reviewed the obstetric, neonatal, and placental pathology information of all non-malformed neonates with birth weight of 750g or less from January 1998 to December 2002. Logistic regression analysis was used to control for the effect of confounding variables. A P<0.05 was considered significant. RESULTS: Fifty nine neonates fulfilled the inclusion criteria; 30 (51%) survived the perinatal period. Surviving neonates were more frequently born after steroid administration (P=0.03) and from indicated delivery (P=0.01), had greater birth weight (P=0.001), gestational age at delivery (P<0.001), and 5-min Apgar scores of 7 or more (P=0.04) than those who died. There were no significant differences in placental pathology between survivors and neonates who died. Stepwise logistic regression analysis showed that gestational age (P=0.01), birth weight (P=0.004), female sex (P=0.03), 5-min Apgar score (0.026), and steroid administration (P=0.04) were independent predictors of survival. Cumulatively these five predictors explained 69% of neonatal survival. CONCLUSIONS: The predictors of survival among micropremies are the same as those reported for older preterm neonates. The type of preterm delivery (spontaneous versus indicated) and placental pathology do not independently affect survival.

The impact of first-trimester screening on AMA patients' uptake of invasive testing.

OBJECTIVE: Prenatal testing for AMA includes invasive procedures such as CVS and amniocentesis, which have risks. We sought to determine the effects of first-trimester screening (FTS) on referrals for genetic counseling and patients' decisions to pursue invasive testing after FTS was offered in 2002. METHODS: We compared AMA patients presenting for prenatal care who underwent early genetic counseling (<13 weeks' gestation) from 2001 to those from 2003. Charts were reviewed for maternal age, gestational age, past obstetric history, prior CVS or amniocentesis, abnormal ultrasound findings and decision to proceed with invasive testing. The two groups were compared using Student t-test and chi-square tests. RESULTS: In 2001, 552 AMA women enrolled in prenatal care; 68 presented for early genetic counseling. In 2003, 728 AMA women enrolled in prenatal care; 172 presented for early genetic counseling. More counseled women chose genetic testing in 2003 than in 2001 (95% vs 79%, p<0.01). More patients elected an invasive procedure in 2001 compared to 2003 (71% vs 26%, p<0.01). CONCLUSION: Availability of FTS results in more AMA women having early prenatal genetic counseling and choosing some form of genetic testing. Such women are less likely to choose invasive tests than those without access to FTS.

Duration of labor and risk of cerebral white-matter damage in very preterm infants who are delivered with intrauterine infection.

OBJECTIVE: The purpose of this study was to assess whether the duration of labor has any effect on the occurrence of cerebral white-matter damage in very preterm infants who are delivered in the presence of intrauterine infection. STUDY DESIGN: From a cohort of infants who were born spontaneously at <32 weeks of gestation for whom placental information was available and who survived 7 days from birth, 126 infants had clinical, laboratory, or histologic evidence of intrauterine infection. Among them, variables were compared between those infants with white-matter damage (defined as intraventricular hemorrhage grade 3 plus, periventricular leukomalacia, or ventriculomegaly not associated with hydrocephaly [n = 13]) and those infants without it (n = 113). Comparisons were made with t test, chi-squared test, and survival analysis; a probability value of <.05 was considered significant. RESULTS: There were no differences between the 2 groups in gestational age at delivery and rates of labor or cesarean delivery. Duration of active labor (66 +/- 45 minutes vs 88 +/- 75 minutes; P =.49) and of clinical chorioamnionitis (310 +/- 186 minutes vs 529 +/- 544 minutes; P =.44) were similar in cases with and without neonatal white-matter damage. CONCLUSION: In 126 infants who were born at <32 weeks of gestation with intrauterine infection, we found no correlation between the duration of labor or clinical chorioamnionitis and neonatal white-matter damage.

Gestational age at preterm premature rupture of membranes: a risk factor for neonatal white matter damage.

OBJECTIVE: Gestational age at delivery and spontaneous prematurity are independent risk factors for white matter damage (WMD). However, among infants delivered spontaneously after preterm premature rupture of membranes (PPROM), latency of PPROM has been inconsistently correlated with risk of WMD. We have explored whether gestational age at membrane rupture is independently associated with WMD. STUDY DESIGN: Using a cohort of 196 liveborn singleton nonanomalous neonates born at 24.0 to 33.6 weeks from January 1993 to December 2002 after pPROM and who survived 7 days, we compared the characteristics of those who developed WMD (n = 15) with those who did not (n = 181) using Fisher exact test, Student t test, and logistic regression analysis, with a 2-tailed P < .05 or odds ratio (OR) with 95% CI not inclusive of the unity considered significant. RESULTS: Stepwise logistic regression analysis demonstrated that gestational age at PPROM (P < .001, OR 0.79) was significantly associated with WMD. The association was independent of corticosteroid administration (P = .016), latency interval (P = .69), gestational age at delivery (P = .99), and birth weight (P = .62). CONCLUSION: Among premature infants born at <34 weeks after pPROM, gestational age at diagnosis is independently associated with WMD.

Antenatal predictors of neonatal outcome in fetal growth restriction with absent end-diastolic flow in the umbilical artery.

OBJECTIVE: Absent end-diastolic blood flow in the umbilical artery identifies growth-restricted fetuses at high risk of perinatal mortality and severe morbidity. We explored antenatal variables predictive of perinatal mortality or severe neonatal morbidity in such fetuses. STUDY DESIGN: We accessed a cohort of 39 singleton, non-malformed, growth-restricted fetuses with absent end-diastolic blood flow at less than 34 weeks between January 1995 and December 2004. The ratio of umbilical artery pulsatility index to middle cerebral artery pulsatility index was calculated to assess redistribution of the fetal arterial circulation. Prenatal and neonatal variables were compared between subjects with versus those without perinatal mortality or severe morbidity using unpaired Student t test or Fisher exact test. Statistical analysis included stepwise logistic regression and receiver operating characteristic curve analysis. P < .05 was considered significant. RESULTS: Stepwise logistic regression analysis demonstrated that the last umbilical artery/middle cerebral artery ratio (P = .02) and estimated fetal weight before delivery (P = .02) were independent predictors of adverse neonatal outcome, with an umbilical artery/middle cerebral artery ratio 1.9 or greater having a sensitivity of 75% and a 13% false-positive rate. Umbilical artery/middle cerebral artery ratio alone accounted for 54% of the variability in outcome. CONCLUSIONS: Among preterm growth-restricted fetuses with absent end-diastolic blood flow in the umbilical artery, the umbilical artery/middle cerebral artery ratio is the best predictor of neonatal mortality or severe morbidity.

Fetal genotype for specific inherited thrombophilias is not associated with severe preeclampsia.

OBJECTIVE: Little is known about the association between fetal thrombophilias and severe preeclampsia. The objective of this study was to examine the association between fetal genotype for factor V Leiden, prothrombin, and methylene tetrahydrofolate reductase (MTHFR) mutations and severe preeclampsia. METHODS: Patients with severe preeclampsia or HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome admitted to Georgetown University Hospital were retrospectively identified. Controls were patients with uncomplicated, term deliveries. Fetal DNA was extracted from placental specimens and amplified by polymerase chain reaction (PCR) with locus-specific primers. The presence of polymorphisms was determined by enzymatic digestion with specific enzymes, and analyzed by polyacrylamide gels. Statistical analysis used Student t test for continuous variables and Fisher exact test for categorical data. RESULTS: Patients with preeclampsia (n = 27) and controls (n = 17) were similar for maternal age, but, as expected, they were significantly different for gestational age at delivery, birth weight, Apgar scores at 5 minutes, rate of preterm delivery less than 37 weeks, and fetal growth restriction (all P <.05). DNA extraction was successful in 25 of 27 cases from the severe preeclampsia group and 14 of 17 controls. None of the placentas analyzed in the preeclamptic or control group revealed mutations in the factor V Leiden or prothrombin genes. There was no significant difference in the rate of fetuses heterozygous for MTHFR in the preeclampsia versus control group (48% vs 43%, P >.05). CONCLUSION: In our study, fetal genotype for specific inherited thrombophilias does not appear to be associated with severe preeclampsia.

Fetal arrhythmias: natural history and management.

The aim was to delineate the significance and natural history of fetal arrhythmias and provide information about their management. A cohort of 114 infants with fetal arrhythmias detected during prenatal ultrasound (US) screening were studied. All subjects underwent echocardiography and were treated as clinically indicated. Postnatal outcome was obtained in 100% of infants until 1 year of age. The incidence of fetal arrhythmias was 0.3%. Among the 87 fetuses with atrial extrasystoles, 2.3% developed supraventricular tachycardia (SVT) in utero. Of the 10 SVT cases, only five required antiarrhythmic therapy in utero with digoxin and propafenone, which successfully restored sinus rhythm in 100% of fetuses, both nonhydropic and hydropic. Sinus bradycardia was associated with structural anomalies in 5 of 6 patients and only 2 of 4 fetuses with atrioventricular block survived. It is concluded that prognosis is good for most fetal tachyarrhythmias, whereas it is less favorable for bradyarrhythmias.

Antenatal magnesium treatment and neonatal illness severity as measured by the Score for Neonatal Acute Physiology (SNAP).

OBJECTIVE: . To determine if antepartum administration of magnesium sulfate affects the Score for Neonatal Acute Physiology (SNAP). METHODS: We reviewed a database of consecutive preterm admissions to our neonatal intensive care unit over a 12-month period. Information on delivery indication, magnesium sulfate use, betamethasone administration, neonatal SNAP scores, neonatal serum magnesium levels, and other data was collected. Data was analyzed by Chi-square, Student t-test, and multiple linear regression with P < 0.05 considered significant. RESULTS: During the study period, 221 cases fulfilled inclusion and exclusion criteria. Multiple regression revealed a significant association between antepartum magnesium use and improved SNAP scores after controlling for gestational age, glucocorticoid use, chorioamnionitis, and birthweight (SNAP score reduction = -2.25 +/- 0.78, P = 0.005). CONCLUSIONS: Antepartum administration of magnesium sulfate results in a significant improvement in the neonatal SNAP score. These results suggest that antepartum magnesium sulfate may be protective, or at least not detrimental to the newborn infant.

Histologic placental lesions in women with recurrent preterm delivery.

BACKGROUND: The aim of this study was to evaluate whether particular placental histopathology lesions are associated with recurrent preterm birth. METHODS: We analyzed a database of 413 consecutive singleton pregnancies delivered at <32 weeks with past reproductive history available. After the exclusion of nulliparous women, the pregnancies were divided according to the obstetrical history into group 1 (n = 328), women without prior preterm delivery (PTD); group 2 (n = 49), women with one prior preterm childbirth; and group 3 (n = 36), women with > or =2 prior preterm deliveries. Demographic and clinical variables were compared among the three groups by using Kruskal-Wallis test and chi-square test for trend. Finally, the individual placental lesions (i.e. 42 lesions of acute or chronic inflammation, uteroplacental vascular pathology, and intraplacental villous lesions) were correlated with the number of prior preterm deliveries by using regression analysis. A two-tailed P < 0.05 was considered significant. RESULTS: No differences were found among the three groups in demographic or clinical variables. Regression analysis of scored placental lesions corrected for gestational age at delivery showed that the number of prior preterm deliveries was correlated only with chronic marginating choriodeciduitis (correlation coefficient = 0.13; P = 0.01) and acute choriodeciduitis (correlation coefficient = 0.14; P = 0.008). CONCLUSIONS: Among women delivered at <32 weeks, those with prior preterm birth have histologic findings compatible with acute or chronic inflammatory involvement of the uterine cavity, suggesting that a prepregnancy endometrial infection rather than an ascending intrapregnancy pathway may be responsible for some recurrences of PTD.

Gender differences of placental dysfunction in severe prematurity.

OBJECTIVE: Rates of several obstetric complications have been reported to vary with fetal gender. We investigated whether a sex difference exists in findings at placental histology of extreme prematurity. DESIGN: Case-control study. SETTING: University Hospital. POPULATION: Four hundred and thirty-seven consecutive deliveries before 32 weeks of gestation of singleton, liveborn, non-anomalous infants. METHODS: Obstetric, neonatal and placental histologic findings were compared between male (n= 232) and female (n= 205) neonates. MAIN OUTCOME MEASURES: Histologic evidence of acute placental inflammation, uteroplacental vascular pathology, intraplacental vascular pathology and chronic placental inflammation. RESULTS: Male fetuses had similar racial distributions, rate of nulliparity, maternal age, gestational age at delivery, placental weight and fetoplacental weight ratio as female fetuses, but higher birthweight centiles (41 [27] vs 33 [26]). Placental histology showed no association between fetal gender and lesions of acute inflammation (P= 0.08), intraplacental vascular pathology (P= 0.16) or uteroplacental vascular pathology (P= 0.83). However, lesions of chronic inflammation had a significantly higher score in male than in female fetuses (P= 0.001). When we examined the distribution of chronic placental inflammation, significantly more severe lesions were noted in male than in female fetuses at the implantation site (i.e. the area of interstitial trophoblast invasion of the maternal decidua and maternal endovascular trophoblast remodelling), than within the placental villi (chronic villitis) or in the amniochorionic membranes (where interstitial trophoblast invasion is minimal). CONCLUSION: In premature deliveries at <32 weeks, male fetal gender is associated with placental lesions suggestive of a maternal immune response against the invading interstitial trophoblast. The immunologic basis of these findings deserves further studies.

Role of lamellar body count for the prediction of neonatal respiratory distress syndrome in non-diabetic pregnant women.

OBJECTIVE: Lamellar body count is a new and fast technique to establish the presence of fetal lung maturity. We have assessed the predictive ability of lamellar body count for neonatal respiratory distress syndrome (RDS) in a non-diabetic population. STUDY DESIGN: We accessed a cohort of amniocenteses in non-diabetic women from 1998 to 2002 (n=102). Neonatal RDS was defined as need for surfactant, intubation, or continuous positive airway pressure (CPAP) in the setting of chest X-ray findings consistent with RDS. The predictive ability of lamellar body count was compared with those of lecithin/sphingomyelin (L/S) ratio and presence of phosphatidylglycerol (PG) using logistic regression analysis. The optimal threshold value of lamellar body count for prediction of neonatal RDS was established with receiver operating characteristic (ROC) curve analysis. RESULTS: Lamellar body count ROC curve analysis identified a lamellar body count >37,000 microl(-1) as optimal diagnostic threshold for diagnosis of lung maturity, having a negative predictive value of 98%. Lamellar body count and PG, but not L/S ratio, added significantly to the prediction of RDS. CONCLUSIONS: Lamellar body count is a reliable predictor of fetal lung maturity in non-diabetic women and it can replace the L/S ratio.

Preterm twins: what threshold of birth weight discordance heralds major adverse neonatal outcome?

OBJECTIVE: This study was undertaken to establish the optimal threshold of birth weight discordance for prediction of adverse outcome in liveborn, non-malformed preterm twins. STUDY DESIGN: We accessed a cohort of twin gestations for the period 1990 through 2000 delivered at less than 37.0 weeks' gestation. Adverse neonatal outcome was defined as stillbirth or occurrence of major morbidities. RESULTS: A total of 335 twin gestations (670 twins) were included, of which 104 (31%) experienced adverse neonatal outcome. The average birth weight discordance was 12.4% +/- 10.6% versus 19.4% +/- 14.8% in those with good versus adverse outcome (P < .001). Birth weight discordance was a significant predictor of adverse neonatal outcome that was independent of gestational age at delivery, small for gestational age, and chorionicity. Receiver operating characteristic curve analysis suggested that optimal thresholds of birth weight discordance for clinical use should take into account gestational age. CONCLUSION: Birth weight discordance is an independent predictor of adverse neonatal outcome in liveborn, non-malformed preterm twins.

Randomized trial of McRoberts versus lithotomy positioning to decrease the force that is applied to the fetus during delivery.

OBJECTIVE: In an effort to reduce shoulder dystocia incidence and morbidity, some obstetricians use prophylactic maternal hip hyperflexion (McRoberts maneuver), with the hope of facilitating delivery and decreasing the traction needed for delivery. The objective of this study was to evaluate whether the delivery force is reduced with the prophylactic McRoberts maneuver in a prospective, objective manner. STUDY DESIGN: Between April 2002 and July 2003, we randomly assigned multiparous women with term, cephalic singleton gestations to delivery in the lithotomy or McRoberts position. A single physician used a force-measuring system that consisted of a custom glove with force sensors to record the amount of force that was exerted on the fetal head. The primary outcomes of the study were peak force (pounds; highest force needed to accomplish entire delivery), peak force for delivery of anterior shoulder (pounds), and peak force rate (pounds per second; the duration required to reach the peak force). RESULTS: The peak force was not different between the patients in the lithotomy position (n=13) versus the McRoberts position (n=14; 7.2 +/- 0.8 lbs vs 8.0 +/- 0.7 lbs; P = .5). The peak force for delivery of the anterior shoulder (6.7 +/- 0.8 lbs vs 7.1 +/- 0.7 lbs; P = .7) and peak force rate (32.3 +/- 7.0 lbs/sec vs 29.1 +/- 3.5 lbs/sec; P = .7) were not different between the patients in the lithotomy position versus the McRoberts position, respectively. There was no difference between the groups for gestational age, birth weight, incidence of diabetes mellitus, or operative vaginal delivery. The subjective degree of difficulty of the delivery correlated with the peak force (R2 = 0.53; P = .001). CONCLUSION: The use of the McRoberts maneuver before clinical diagnosis of shoulder dystocia provides no reduction in the force that is used in traction on the fetal head during vaginal delivery in multiparous patients. The acceptance of this maneuver to be used prophylactically requires re-evaluation.

A randomised controlled trial of ursodeoxycholic acid and S-adenosyl-l-methionine in the treatment of gestational cholestasis.

OBJECTIVE: To compare the efficacy of S-adenosyl-l-methionine and ursodeoxycholic acid in improving serum biochemical abnormalities in gestational cholestasis. DESIGN: Randomised clinical trial. SETTING: University hospital. POPULATION: All women at <36 weeks of gestation with severe gestational cholestasis during June 1996 to December 2001. METHODS: Enrolled women were randomly assigned oral S-adenosyl-l-methionine 500 mg twice daily or oral ursodeoxycholic acid 300 mg twice daily until delivery. MAIN OUTCOME MEASURES: Reduction in the concentration of serum bile acids. Other variables considered included obstetric and neonatal outcome, clinical symptoms and other laboratory measurements (serum levels of transaminases and bilirubin). The two groups were compared using Student's t test, Wilcoxon's signed rank sum test and Fisher's exact test, with a two-tailed P < 0.05 being considered significant. RESULTS: Of the 46 women enrolled, 24 received ursodeoxycholic acid and 22 S-adenosyl-l-methionine. At enrolment, gestational age, duration of therapy, rate of nulliparity, pruritus score and biochemical characteristics were similar between the groups. Both therapies significantly and equally improved pruritus. Women receiving ursodeoxycholic acid had a significantly greater improvement in the concentration of serum bile acids (P= 0.001), aspartate aminotransferase (P= 0.01), alanine aminotransferase (<0.001) and bilirubin (P= 0.002) compared with those receiving S-adenosyl-l-methionine. Duration of therapy was significantly greater in women receiving ursodeoxycholic acid compared with S-adenosyl-l-methionine (P= 0.04), whereas gestational age at delivery and rate of prematurity were similar in the two groups. CONCLUSIONS: In women with intrahepatic cholestasis of pregnancy, ursodeoxycholic acid is more effective than S-adenosyl-l-methionine at improving the concentration of serum bile acids and other tests of liver function, whereas both therapies are equally effective at improving pruritus.

Predictors of adverse perinatal outcome in twins delivered at < 37 weeks.

OBJECTIVE: Multiple gestations are at increased risk for prematurity as well as perinatal mortality and morbidity. The aim of this study was to identify the independent risk factors for adverse perinatal outcome in a large uniform population of twins delivered preterm. METHODS: We accessed a cohort of twin gestations for the period 1990-2000 delivered at < 37.0 weeks gestation. Chorionicity was established by ultrasound assessment of the dividing membrane, neonatal gender and histologic examination of the placenta at birth. Adverse perinatal outcome was defined as stillbirth, neonatal death, or major neonatal complications. Statistical analysis used contingency tables, Student's t test, one-way ANOVA and logistic regression, with a two-tailed p < 0.05 considered significant. RESULTS: A total of 356 twin gestations (712 twins) were included in the database, and 183 twins (25.7%) had adverse perinatal outcome. Logistic regression analysis demonstrated that gestational age at delivery (p < 0.001), premature rupture of membranes (PROM) (p = 0.004), birth weight discordance (p = 0.009), and 5-min Apgar scores (p = 0.001) were significant and independent predictors of adverse perinatal outcome, whereas monochorionicity and twin-twin transfusion syndrome were not. CONCLUSIONS: Gestational age at delivery and birth weight discordance are the most important independent predictors of perinatal mortality or morbidity among preterm twins.

Intraventricular hemorrhage and periventricular leukomalacia in preterm infants.

OBJECTIVE: To evaluate whether intraventricular hemorrhage and periventricular leukomalacia are characterized by different risk factors. METHODS: In a cohort of 653 consecutive singleton neonates born after preterm membrane rupture, spontaneous preterm labor, or indicated preterm delivery at 24 to 33 weeks of gestation from January 1, 1993, to December 31, 2002, we evaluated the obstetric and histopathologic placental variables in reference to the development of intraventricular hemorrhage (n = 44), periventricular leukomalacia (n = 19), or no ultrasonographic cerebral lesion (n = 589). Excluded were stillbirths and congenital anomalies. Statistical analysis included Fisher exact test, Student t test, and stepwise logistic regression analysis with a 2-tailed P <.05 considered significant. RESULTS: Multivariate analysis showed that occurrence of neonatal intraventricular hemorrhage and periventricular leukomalacia were associated only with spontaneous prematurity (odds ratio = 1.9; 95% confidence interval 1.1-3.4) and gestational age at delivery in weeks (odds ratio = 0.8; 95% confidence interval 0.7-0.9). Neonates with intraventricular hemorrhage did not differ from those with periventricular leukomalacia in any obstetric or neonatal variable, but there was a higher risk of neurodevelopmental delay associated with periventricular leukomalacia. CONCLUSION: Among premature infants born at less than 34.0 weeks of gestation, intraventricular hemorrhage and periventricular leukomalacia share common clinical characteristics, with spontaneous preterm delivery and gestational age at delivery as the only independent antenatal predictors.
