The purpose of this study was to assess the usefulness of the white cell ratio of immature neutrophils (PMNs) to total (immature plus mature) PMNs as an indication of infection in the very small premature infant. We retrospectively reviewed the charts of 59 premature infants less than or equal to 1,250 g admitted to our Newborn Intensive Care Unit over a one-year period who had at least one white count determined. Twenty-three were born after rupture of membranes for greater than or equal to 24 hours (PROM), 47 had a one-minute Apgar score less than or equal to 6 and 31 had a five-minute Apgar scores less than or equal to 6, 38 had respiratory distress syndrome (RDS), and 4 had confirmed infection. Thirty-one of the infants had a ratio greater than or equal to .15 in the first day of life, a value which has been suggested in the literature as being abnormal and an indication to suspect sepsis. This ratio bore no statistical relationship to PROM, low Apgar scores, or RDS. We analyzed these same relationships using a ratio greater than or equal to .25, another ratio derived from data in the literature which has been said to suggest infection. No statistical correlation was found for low Apgars or RDS, but there was a significant relationship between PROM and attainment of a ratio greater than or equal to .25 (p less than .005). It is notable that 2 out of the 4 infants with infection had a ratio less than .15. We wish to cast doubt on the applicability of the currently defined WBC ratios in the literature as they apply to the infant with birth weight less than 1,250 g and emphasize the apparent effect of PROM as a factor upon these ratios.

One hundred patients with term pregnancy, were studied. There were placed in two groups of 50 each; one was the problem group with antecedents and confirmation of premature rupture of membranes; and the other group with intact amnios at the time of delivery, which served as controls. Clinical history, leukocyte count, temperature determination on admission and during trans-partum, leukocyte count in mixed blood from the umbilical cord and clinical surveillance were carried out, until 96 hours after delivery, of mother and child looking for sepsis signs. In the problem group there were 10 cases of maternal infection and 12 of newborns. There were no infections in the control group. There was no perinatal mortality. The most useful examination as to maternal and neonatal infection, was leukocytic count on admission, followed by trans-partum count and maternal temperature. Fetal leukocytic count above 12,500 per mm3 was useful in 70% of the newborns with complications.

To evaluate the utility of conventional electronic fetal monitoring in detection of established perinatal sepsis, we conducted a case-controlled study of fetal monitor results in 18 patients delivering newborns with sepsis. Eleven of the 18 newborns (61%) demonstrated clinically reassuring fetal heart rate patterns, not significantly different from controls (p = 0.80). No pattern predictive of presumed perinatal sepsis could be identified. Obstetric factors traditionally associated with increased risk of perinatal infection, such as long duration of labor, use of internal fetal monitoring, and increased number of vaginal examinations were not significantly different from controls. Preterm rupture of membranes greater than 24 hours occurred in less than 50% of the cases. Clinical diagnosis of chorioamnionitis was established in only one third of the patients who delivered newborns with sepsis. In this study, use of conventional electronic fetal monitoring did not accurately identify newborns with presumed intrauterine infection.

The purpose of this prospective investigation was to evaluate a protocol for management of term patients with premature rupture of membranes (PROM) and a cervix unfavorable for induction of labor (Bishop score 4 or less). Patients initially were observed for 24 to 36 hours for the spontaneous onset of labor. If spontaneous contractions did not commence, labor was induced with oxytocin. Patients subsequently were divided into three groups: 44 who had spontaneous labor, 29 who had spontaneous labor but required oxytocin augmentation, and 39 women who had oxytocin induction. Patients who entered labor spontaneously had a significantly shorter mean latent period between rupture of membranes and onset of labor (16.0 versus 26.8 and 40.7 hours), shorter mean duration of labor (7.6 versus 12.1 and 13.1 hours), and shorter mean duration of rupture of membranes (23.6 versus 39.0 and 53.8 hours). These women also had a significant decrease in the frequency of chorioamnionitis (7 versus 14 and 33%), and their infants had fewer evaluations for sepsis (25.0 versus 34.5 and 53.8%). We conclude that term patients with PROM and an unfavorable cervix who require oxytocin augmentation or induction of labor are at increased risk for intrapartum and neonatal infection compared with those who progress through labor spontaneously.

PROM is one of the most common complications of pregnancy that has a major impact on neonatal mortality and morbidity. The occurrence of PROM is either directly or indirectly responsible for a large number of premature births and the concomitant mortality and morbidity associated with preterm delivery. PROM turns a pregnancy into a high-risk situation and increases the need for neonatal resuscitation in the delivery room. The incidence of neonatal sepsis increases with PROM, but the overall outcome of the neonate, even with surfactant therapy, is still primarily dependent on the gestational age at the time of delivery. This is most relevant between 24 and 27 weeks' gestation. During this 3-week interval, survival improves by almost 2% for each additional day of in utero maturation (i.e., from 35 to 75%). Thus the benefit to the fetus of prolonging the pregnancy in cases of PROM is immensely worthwhile and should be aggressively pursued as long as there is no significant increase in maternal morbidity.

In summarizing the published data on the use of amniocentesis and fetal biophysical assessment in managing patients with PROM the following conclusions may be drawn: 1. Both amniocentesis and fetal biophysical assessment are reasonably good methods to predict the fetus who is doing well and could therefore safely remain in utero, as well as the fetus who is at high risk for developing sepsis and therefore in need of delivery. 2. Consideration of routine transabdominal amniocentesis for Gram stain and cultures in patients with PROM is reasonable. Measurements of glucose levels, esterase activity, or cytokines are only investigational, and their use in patient management cannot be advocated at this time. 3. Although there are no prospective controlled randomized trials to prove improved pregnancy outcome by the use of either amniocentesis or frequent biophysical assessment, nonrandomized comparative trials as well as trials using historic controls suggest that the use of either or both techniques in combination may be beneficial in managing PROM.

A retrospective analysis has been performed of perinatal outcome in 81 pregnancies in which preterm premature rupture of membranes (PPROM) was managed using amniocentesis to diagnose intrauterine infection and lung maturity. Ten patients (13%) had a positive Gram stain on microscopy whilst 29 (37%) had a positive culture. Forty-one patients (58%) had a mature lecithin:sphingomyelin ratio. There was evidence of sepsis in 13 neonates (16%), with a further 16 (20%) being colonized. Both Gram stain and amniotic fluid culture were relatively poor predictors of neonatal sepsis. For Gram stain the sensitivity was low at only 15%. Although the sensitivity for culture was higher (69%), the specificity (71%) was too low to be clinically useful. It is recommended that a randomized controlled trial of amniocentesis in PPROM is needed to define the role of this diagnostic test.

Diabetes in pregnant Mexican-American women is a serious and expensive health problem. At the University of California, San Diego Medical Center, 44% of pregnant women are Mexican American. In the Diabetes in Pregnancy Clinic, only 7% of women with insulin-dependent diabetes are in this ethnic group compared with 66% of non-insulin-dependent diabetic patients and 51% of those with gestational diabetes mellitus (GDM). GDM is the most common complication of pregnancy in Mexican Americans with a prevalence approximately three times higher than that of whites (4.5 vs. 1.5%). Mexican-American obese GDM subjects had more frequent cesarean sections and were more likely to have complications of premature rupture of membranes and preterm labor (NS). Polycythemia and sepsis also occurred more often in their infants. Anthropometric measurements in infants of both lean and obese GDM subjects differed from those of infants of mothers without GDM. Infants of lean mothers with GDM were heavier and longer than those of lean mothers without GDM. In addition, they had increased waist-hip ratio and triceps and subscapular skin folds. Infants of obese mothers with GDM were heavier than those of lean mothers with GDM. Moreover, they were longer (P less than 0.04); had a higher body mass index (P less than 0.04); and larger waist and hip circumferences (P less than 0.03) and buccal (P less than 0.01), subscapular (P less than 0.01), and sum of skin-fold measurements (P less than 0.03). Our observations indicate that pregnant diabetic Mexican-American women have predominantly GDM and non-insulin-dependent diabetes. They represent a major public health problem because of increased maternal and neonatal morbidity.

A modified biophysical profile was assessed serially in 47 patients with premature rupture of membranes who were not in labor. This profile included fetal movement, fetal tone, fetal breathing, amniotic fluid volume, and placental grade. The most recent study, obtained within 2 days of delivery, was compared with pregnancy outcome as reflected by the development of chorioamnionitis and/or neonatal sepsis. No study patient received antibiotics, steroids, or tocolytics before labor. Neither the composite biophysical profile nor any of its components were found to be different between patients with and without clinical chorioamnionitis. Neonatal sepsis was not observed. These data do not support the use of the biophysical profile as a predictor of maternal infection.

The use of antibiotics in the management of preterm, premature rupture of membranes remains controversial. By use of a prospective randomized double-blind design we investigated the maternal-fetal benefits associated with antibiotic therapy in 85 women with premature rupture of membranes at 34 weeks' estimated gestational age. In the treatment group 40 patients received intravenous mezlocillin for 48 hours followed by oral ampicillin until delivery. In the control group 45 patients received intravenous and oral placebo. Patients who received antibiotics had chorioamnionitis and endometritis less frequently than the control group (p less than 0.01 and p less than 0.05). Pathologic examination of the placentas showed a lower incidence of chorioamnionitis in the treatment group (p less than 0.05). The period from premature rupture of membranes to delivery (latency) was prolonged with antibiotics (p less than 0.05) and resulted in significant weight gain in the infants in the antibiotic group (p less than 0.0001). These infants also had higher 1- and 5-minute Apgar scores. Clinically suspected sepsis, respiratory distress syndrome, intraventricular hemorrhage, perinatal death rate, and prolonged hospitalization (greater than 30 days) were also increased in the control group.
