Subcutaneous tissue reapproximation, alone or in combination with drain, in obese women undergoing cesarean delivery.

OBJECTIVE: To compare the efficacy of subcutaneous suture reapproximation alone with suture plus subcutaneous drain for the prevention of wound complications in obese women undergoing cesarean delivery. METHODS: We conducted a multicenter randomized trial of women undergoing cesarean delivery. Consenting women with 4 cm or more of subcutaneous thickness were randomized to either subcutaneous suture closure alone (n = 149) or suture plus drain (n = 131). The drain was attached to bulb suction and removed at 72 hours or earlier if output was less than 30 mL/24 h. The primary study outcome was a composite wound morbidity rate (defined by any of the following: subcutaneous tissue dehiscence, seroma, hematoma, abscess, or fascial dehiscence). RESULTS: From April 2001 to July 2004, a total of 280 women were enrolled. Ninety-five percent of women (268/280) had a follow-up wound assessment. Both groups were similar with respect to age, race, parity, weight, cesarean indication, diabetes, steroid/antibiotic use, chorioamnionitis, and subcutaneous thickness. The composite wound morbidity rate was 17.4% (25/144) in the suture group and 22.7% (28/124) in the suture plus drain group (relative risk 1.3, 95% confidence interval 0.8-2.1). Individual wound complication rates, including subcutaneous dehiscence (15.3% versus 21.8%), seroma (9.0% versus 10.6%), hematoma (2.2% versus 2.4%), abscess (0.7% versus 3.3%), fascial dehiscence (1.4% versus 1.7%), and hospital readmission for wound complications (3.5% versus 6.6%), were similar (P > .05) between women treated with suture alone and those treated with suture plus drain, respectively. CONCLUSION: The additional use of a subcutaneous drain along with a standard subcutaneous suture reapproximation technique is not effective for the prevention of wound complications in obese women undergoing cesarean delivery.

Maternal and perinatal outcomes associated with a trial of labor after prior cesarean delivery.

BACKGROUND: The proportion of women who attempt vaginal delivery after prior cesarean delivery has decreased largely because of concern about safety. The absolute and relative risks associated with a trial of labor in women with a history of cesarean delivery, as compared with elective repeated cesarean delivery without labor, are uncertain. METHODS: We conducted a prospective four-year observational study of all women with a singleton gestation and a prior cesarean delivery at 19 academic medical centers. Maternal and perinatal outcomes were compared between women who underwent a trial of labor and women who had an elective repeated cesarean delivery without labor. RESULTS: Vaginal delivery was attempted by 17,898 women, and 15,801 women underwent elective repeated cesarean delivery without labor. Symptomatic uterine rupture occurred in 124 women who underwent a trial of labor (0.7 percent). Hypoxic-ischemic encephalopathy occurred in no infants whose mothers underwent elective repeated cesarean delivery and in 12 infants born at term whose mothers underwent a trial of labor (P<0.001). Seven of these cases of hypoxic-ischemic encephalopathy followed uterine rupture (absolute risk, 0.46 per 1000 women at term undergoing a trial of labor), including two neonatal deaths. The rate of endometritis was higher in women undergoing a trial of labor than in women undergoing repeated elective cesarean delivery (2.9 percent vs. 1.8 percent), as was the rate of blood transfusion (1.7 percent vs. 1.0 percent). The frequency of hysterectomy and of maternal death did not differ significantly between groups (0.2 percent vs. 0.3 percent, and 0.02 percent vs. 0.04 percent, respectively). CONCLUSIONS: A trial of labor after prior cesarean delivery is associated with a greater perinatal risk than is elective repeated cesarean delivery without labor, although absolute risks are low. This information is relevant for counseling women about their choices after a cesarean section.

Time course of the regression of asymptomatic bacterial vaginosis in pregnancy with and without treatment.

OBJECTIVE: The purpose of this study was to determine the effectiveness of treatment over time for bacterial vaginosis in pregnancy and the probability of spontaneous resolution with placebo. STUDY DESIGN: Women with asymptomatic bacterial vaginosis on Gram stain were assigned randomly at 16 to 23 weeks of gestation to receive two 2-g doses of metronidazole or placebo 48 hours apart and were re-evaluated for changes in Gram stain score on one occasion > or =2 weeks later. RESULTS: Of 658 women who underwent metronidazole therapy, treatment was successful (score, <7) in 78% of those women who were seen at 2 to 3.9 weeks of gestation, which was similar to women seen > or =10 weeks after treatment. In 683 women who underwent placebo therapy, spontaneous resolution increased significantly from 13% at 2 to 3.9 weeks of gestation to 36% at > or =10 weeks of gestation. Spontaneous resolution was more common with lower vaginal pH or lactobacilli on Gram stain at the time of random assignment. CONCLUSION: The effectiveness of metronidazole therapy of bacterial vaginosis persists for > or =10 weeks. Women who underwent placebo therapy had significant remission of bacterial vaginosis over > or =10 weeks. Remission was more common when the initial vaginal microbiologic disturbances were less severe.

Randomized trial of inhaled beclomethasone dipropionate versus theophylline for moderate asthma during pregnancy.

OBJECTIVE: This study was undertaken to compare the efficacy of inhaled beclomethasone dipropionate to oral theophylline for the prevention of asthma exacerbation(s) requiring medical intervention. STUDY DESIGN: A prospective, double-blind, double placebo-controlled randomized clinical trial of pregnant women with moderate asthma was performed. RESULTS: There was no significant difference (P=.554) in the proportion of asthma exacerbations among the 194 women in the beclomethasone cohort (18.0%) versus the 191 in the theophylline cohort (20.4%; risk ratio [RR]=0.9, 95% CI=0.6-1.3). The beclomethasone cohort had significantly lower incidences of discontinuing study medications caused by side effects (RR=0.3, 95% CI=0.1-0.9; P=.016), and proportion of study visits with forced expiratory volume expired in 1 second (FEV1) less than 80% predicted (0.284+/-0.331 vs 0.284+/-0.221, P=.039). There were no significant differences in treatment failure, compliance, or proportion of peak expiratory flow rate less than 80% predicted. There were no significant differences in maternal or perinatal outcomes. CONCLUSION: The treatment of moderate asthma with inhaled beclomethasone versus oral theophylline resulted in similar rates of asthma exacerbations and similar obstetric and perinatal outcomes. These results favor the use of inhaled corticosteroids for moderate asthma during pregnancy because of the improved FEV1 and because theophylline had more side effects and requires serum monitoring.

Umbilical cord plasma interleukin-6 concentrations in preterm infants and risk of neonatal morbidity.

OBJECTIVE: This study was undertaken to evaluate the association between umbilical cord interleukin-6 (IL-6) levels and neonatal morbidity in infants born at less than 32 weeks' gestation. STUDY DESIGN: Umbilical cord plasma IL-6 levels and neonatal outcomes were assessed in 309 infants born between 24 weeks and 0 days' and 31 weeks and 6 days' gestation. RESULTS: Mean IL-6 levels were higher in spontaneous (n = 193, 355 +/- 1822 pg/mL) compared with indicated preterm births (n = 116, 37 +/- 223 pg/mL, P < .0001). Adjusting for gestational age, a progressive relationship was noted between increasing IL-6 levels and increased risk of neonatal systemic inflammatory response syndrome (SIRS). IL-6 levels beyond the 90th percentile (> or =516.6 pg/mL) were also significantly associated with periventricular leukomalacia (PVL; odds ratio [OR] 15, 95% CI 2-149) and necrotizing enterocolitis (NEC; OR 6, 95% CI 1.1-33). In the multivariate analysis, an IL-6 level 107.7 pg/mL or greater (determined by receiver operating curve analysis) remained a significant independent risk factor for PVL (OR 30.3, 95% CI 4.5-203.6). CONCLUSION: Umbilical cord IL-6 levels are higher in preterm infants born after spontaneous preterm labor or premature rupture of membranes. Elevated IL-6 levels are associated with an increased risk for SIRS, PVL, and NEC in infants born at less than 32 weeks' gestation.

The relationship of asthma medication use to perinatal outcomes.

BACKGROUND: Maternal asthma has been reported to increase the risk of preeclampsia, preterm deliveries, and lower-birth-weight infants, but the mechanisms of this effect are not defined. OBJECTIVE: We sought to evaluate the relationship between the use of contemporary asthma medications and adverse perinatal outcomes. METHODS: Asthmatic patients were recruited from the 16 centers of the National Institute of Child Health and Human Development Maternal Fetal Medicine Units Network from December 1994 through February 2000. Gestational medication use was determined on the basis of patient history at enrollment and at monthly visits during pregnancy. Perinatal data were obtained at postpartum chart reviews. Perinatal outcome variables included gestational hypertension, preterm births, low-birth-weight infants, small-for-gestational-age infants, and major malformations. RESULTS: The final cohort included 2123 asthmatic participants. No significant relationships were found between the use of inhaled beta-agonists (n=1828), inhaled corticosteroids (n=722), or theophylline (n=273) and adverse perinatal outcomes. After adjusting for demographic and asthma severity covariates, oral corticosteroid use was significantly associated with both preterm birth at less than 37 weeks' gestation (odds ratio, 1.54; 95% CI, 1.02-2.33) and low birth weight of less than 2500 g (odds ratio, 1.80; 95% CI, 1.13-2.88). CONCLUSIONS: Use of inhaled beta-agonists, inhaled steroids, and theophylline do not appear to increase perinatal risks in pregnant asthmatic women. The mechanism of the association between maternal oral corticosteroid use and prematurity remains to be determined.

Asthma during pregnancy.

OBJECTIVE: To determine neonatal and maternal outcomes stratified by asthma severity during pregnancy by using the 1993 National Asthma Education Program Working Group on Asthma and Pregnancy definitions of asthma severity. The primary hypothesis was that moderate or severe asthmatics would have an increased incidence of delivery at <32 weeks of gestation compared with nonasthmatic controls. METHODS: This was a multicenter, prospective, observational cohort study conducted over 4 years at 16 university hospital centers. Asthma severity was defined according to the National Asthma Education Program Working Group on Asthma and Pregnancy classification and modified to include medication requirements. This study had 80% power to detect a 2- to 3-fold increase in delivery less than 32 weeks of gestation among the cohort with the moderate or severe asthma compared with controls. Secondary outcome measures included obstetrical and neonatal outcomes. RESULTS: The final analysis included 881 nonasthmatic controls, 873 with mild asthma, 814 with moderate, and 52 with severe asthma. There were no significant differences in the rates of preterm delivery less than 32 weeks (moderate or severe 3.0%, mild 3.4%, controls 3.3%; P =.873) or less than 37 weeks of gestation. There were no significant differences for neonatal outcomes except discharge diagnosis of neonatal sepsis among the mild group compared with controls, adjusted odds ratio 2.9, 95% confidence interval 1.2, 6.8. There were no significant differences for maternal complications except for an increase in overall cesarean delivery rate among the moderate-or-severe group compared with controls (adjusted odds ratio 1.4, 95% confidence interval 1.1, 1.8). CONCLUSION: Asthma was not associated with a significant increase in preterm delivery or other adverse perinatal outcomes other than a discharge diagnosis of neonatal sepsis. Cesarean delivery rate was increased among the cohort with moderate or severe asthma. LEVEL OF EVIDENCE: II-2

Periodontal disease and upper genital tract inflammation in early spontaneous preterm birth.

OBJECTIVE: To estimate the relationship between maternal periodontal disease and both early spontaneous preterm birth and selected markers of upper genital tract inflammation. METHODS: In this case-control study, periodontal assessment was performed in 59 women who experienced an early spontaneous preterm birth at less than 32 weeks of gestation, in a control population of 36 women who experienced an early indicated preterm birth at less than 32 weeks of gestation, and in 44 women with an uncomplicated birth at term (>or = 37 weeks). Periodontal disease was defined by the degree of attachment loss. Cultures of the placenta and umbilical cord blood, cord interleukin-6 levels, and histopathologic examination of the placenta were performed for all women. RESULTS: Severe periodontal disease was more common in the spontaneous preterm birth group (49%) than in the indicated preterm (25%, P =.02) and term control groups (30%, P =.045). Multivariable analyses, controlling for possible confounders, supported the association between severe periodontal disease and spontaneous preterm birth (odds ratio 3.4, 95% confidence interval 1.5-7.7). Neither histologic chorioamnionitis, a positive placental culture, nor an elevated cord plasma interleukin-6 level was significantly associated with periodontal disease (80% power to detect a 50% difference in rate of histological chorioamnionitis, alpha = 0.05). CONCLUSION: Women with early spontaneous preterm birth were more likely to have severe periodontal disease than women with indicated preterm birth or term birth. Periodontal disease was not associated with selected markers of upper genital tract inflammation. LEVEL OF EVIDENCE: II-2

Prevention of recurrent preterm delivery by 17 alpha-hydroxyprogesterone caproate.

BACKGROUND: Women who have had a spontaneous preterm delivery are at greatly increased risk for preterm delivery in subsequent pregnancies. The results of several small trials have suggested that 17 alpha-hydroxyprogesterone caproate (17P) may reduce the risk of preterm delivery. METHODS: We conducted a double-blind, placebo-controlled trial involving pregnant women with a documented history of spontaneous preterm delivery. Women were enrolled at 19 clinical centers at 16 to 20 weeks of gestation and randomly assigned by a central data center, in a 2:1 ratio, to receive either weekly injections of 250 mg of 17P or weekly injections of an inert oil placebo; injections were continued until delivery or to 36 weeks of gestation. The primary outcome was preterm delivery before 37 weeks of gestation. Analysis was performed according to the intention-to-treat principle. RESULTS: Base-line characteristics of the 310 women in the progesterone group and the 153 women in the placebo group were similar. Treatment with 17P significantly reduced the risk of delivery at less than 37 weeks of gestation (incidence, 36.3 percent in the progesterone group vs. 54.9 percent in the placebo group; relative risk, 0.66 [95 percent confidence interval, 0.54 to 0.81]), delivery at less than 35 weeks of gestation (incidence, 20.6 percent vs. 30.7 percent; relative risk, 0.67 [95 percent confidence interval, 0.48 to 0.93]), and delivery at less than 32 weeks of gestation (11.4 percent vs. 19.6 percent; relative risk, 0.58 [95 percent confidence interval, 0.37 to 0.91]). Infants of women treated with 17P had significantly lower rates of necrotizing enterocolitis, intraventricular hemorrhage, and need for supplemental oxygen. CONCLUSIONS: Weekly injections of 17P resulted in a substantial reduction in the rate of recurrent preterm delivery among women who were at particularly high risk for preterm delivery and reduced the likelihood of several complications in their infants.

Randomized clinical trial of extended spectrum antibiotic prophylaxis with coverage for Ureaplasma urealyticum to reduce post-cesarean delivery endometritis.

OBJECTIVE: To determine if extended spectrum prophylactic antibiotic treatment (with efficacy against Ureaplasma urealyticum) reduces post-cesarean delivery clinical endometritis. METHODS: After cord clamping at cesarean delivery, subjects received prophylaxis with cefotetan. Subjects were then simultaneously randomized (double blind) to receive doxycyline plus azithromycin versus placebo. Post-cesarean delivery endometritis was defined clinically as fever of 100.4F or higher with one or more supporting clinical signs or a physician diagnosis of endometritis plus the absence of a nonpelvic source of fever. RESULTS: A total of 597 women were enrolled, 301 in the doxycycline/azithromycin group and 296 in the placebo group. The study population was 56% black, 25.5 +/- 6.2 years of age, and 43% nulliparous. The groups were similar (P >.05) for black race, parity, maternal age, and most risk factors for post-cesarean delivery endometritis. The frequency of post-cesarean delivery endometritis (16.9% versus 24.7%, P =.020), wound infections (0.8% versus 3.6%, P =.030), and a combination of these two outcomes (19.0% versus 27.8%, P =.019) were significantly lower in the doxycycline/azithromycin group compared with the placebo-treated group. The doxycycline/azithromycin versus placebo groups were dissimilar for maternal leukocytosis (24.9% versus 12.5%, P =.042) and frequency of classic uterine incision (7.6% versus 12.5%, P =.048). Adjusting for these factors did not alter the risk ratio for post-cesarean delivery endometritis in the active versus placebo-treated group (relative risk 0.65, 95% confidence interval 0.43, 0.98). Length of stay was longer in the placebo group overall (104 +/- 56 versus 95 +/- 32 hours, P =.016) and among women with endometritis (146 +/- 52 versus 127 +/- 46 hours, P =.047). CONCLUSION: Extended spectrum prophylactic antibiotic treatment (with presumed efficacy against U urealyticum) given to women undergoing cesarean delivery at term shortens hospital stay and reduces the frequency of post-cesarean delivery endometritis and wound infections.

Asthma morbidity during pregnancy can be predicted by severity classification.

BACKGROUND: The 1993 National Asthma Education Program Working Group on Asthma and Pregnancy defined asthma severity as mild, moderate, or severe on the basis of symptoms and spirometry, but no studies have evaluated the relationship between this classification system and subsequent asthma morbidity during pregnancy. OBJECTIVE: The objective of this study was to evaluate the relationship between asthma severity classification during pregnancy and gestational asthma exacerbations. METHODS: Asthma severity was defined according to the 1993 classification, adjusted to include medication requirements, in a volunteer sample of 1739 pregnant asthmatic patients who were less than 26 weeks' gestation. RESULTS: Initial asthma classification (mild, moderate, or severe) was significantly related to subsequent asthma morbidity during pregnancy (hospitalizations, unscheduled visits, corticosteroid requirements, and asthma symptoms during labor and delivery). Exacerbations during pregnancy occurred in 12.6% of patients initially classified as mild, 25.7% of patients classified as moderate, and 51.9% of patients classified as severe (P <.001). Asthma morbidity was similar, whether patients were classified as moderate or severe by symptoms and spirometry or by medication requirement. Thirty percent of initially mild patients were reclassified as moderate-severe during pregnancy, and 23% of the initially moderate-severe patients were reclassified as mild later in pregnancy; asthma morbidity in these patients changed accordingly. CONCLUSION: The National Asthma Education Program Working Group on Asthma and Pregnancy classification of asthma severity, adapted to include medication use, predicts subsequent asthma morbidity during pregnancy.

Vaginal sonography and cervical incompetence.

Uterine contractions, decidual activation, and cervical competence comprise the fundamental components in contemporary models of the spontaneous preterm birth syndrome, but their relative importance and interactive pathways remain poorly defined. Moreover, the traditional concept that the cervix is either competent or incompetent has been challenged because cervical competence more likely functions along a biologic continuum. Cervical incompetence is a clinical diagnosis characterized by recurrent painless dilation and spontaneous midtrimester birth. Although the efficacy of cerclage for cervical incompetence has never been fully confirmed in randomized clinical trials, the role of cerclage has been expanded to include women with "risk factors" for spontaneous preterm birth or nonreassuring sonographic cervical findings in the mid trimester. Evidence from randomized trials suggests that cerclage has limited efficacy in women with risk factors for cervical incompetence. Results of both retrospective cohort series and randomized trials of cerclage in women with shortened cervical length are inconclusive. We believe that women with a prior early spontaneous preterm birth and shortened midtrimester cervical length represent an ideal population for the conduct of a randomized trial of cerclage, which is currently underway.

Early pregnancy threshold vaginal pH and Gram stain scores predictive of subsequent preterm birth in asymptomatic women.

OBJECTIVE: The study was undertaken to identify early pregnancy vaginal markers predictive of subsequent preterm birth. STUDY DESIGN: In a multicenter Bacterial Vaginosis (BV) Trial, 21,554 women were screened with a vaginal pH and of these, two populations were studied. These included 12,041 who had a pregnancy outcome in the database and 6838 women who had a vaginal pH of 4.5 or greater and a Gram stain score and a pregnancy outcome in the database. ColorpHast Indicator Strips were used to determine the vaginal pH and the Nugent criteria were used to determine a vaginal Gram stain score of 0 to 10. RESULTS: Delivery at <37, <35, or <32 weeks' gestation was similar for women with a vaginal pH of less than 4.4 or 4.7 (P not significant) but was increased in women with a pH of 5.0 (P =.04,.02,.03, respectively) or with a pH of 5.0 or greater (at each gestational age P <.0001). The effect of pH of 5.0 or greater was similar for women who had a spontaneous preterm birth at each gestational age (P <.0001) or birth weight of less than 2500 g or less than 1500 g (P <.0005). Women with a vaginal pH of 4.5 or greater and a Gram stain score of 9 to 10 (compared with 0-8) had increased preterm births at <37, <35, and <32 weeks' gestation (P <.01), and birth weights less than 2500 g (P <.0001) or less than 1500 g (P <.01). Women whose vaginal pH was 5.0 or greater had a higher prevalence of vaginal fetal fibronectin > or =50 ng/mL (P <.0001), but the proportion of women with a vaginal fetal fibronectin > or =50 mg/mL did not differ by Gram stain score. CONCLUSION: Women with a vaginal pH of 5.0 or greater or a vaginal pH of 4.5 or greater and a Gram stain score of 9 to 10 had significantly increased preterm births at <37, <35, and 32 weeks' gestation and/or a birth weight less than 2500 g or less than 1500 g.

Clinical trial of chlorhexidine vaginal irrigation to prevent peripartal infection in nulliparous women.

OBJECTIVE: The purpose of this study was to determine whether intrapartum chlorhexidine vaginal irrigations prevent peripartal infection in nulliparous women at >or=32 weeks of gestation. STUDY DESIGN: This was a double-blinded, placebo-controlled randomized clinical trial. Vaginal irrigations were performed with 200 mL of 0.2% chlorhexidine solution or sterile saline solution placebo every 6 hours during labor. The primary study outcome was clinically diagnosed maternal peripartal infection: chorioamnionitis or endometritis. Analysis was by intent to treat. RESULTS: One thousand forty-one women were assigned randomly to one of two groups (chlorhexidine therapy, 525 women; placebo, 516 women). The two groups were balanced for risk factors for infection. Rates of peripartal infection were 19.3% in the chlorhexidine group and 17.3% in the placebo group (relative risk 1.1; 95% CI, 0.9-1.4). Major and minor neonatal morbidities were similar between the groups. No major and one minor adverse reaction was attributed to chlorhexidine irrigation. CONCLUSION: Under the conditions of this trial, chlorhexidine vaginal irrigation lacked efficacy in the prevention of clinically diagnosed maternal and neonatal infectious morbidity.

Periodontal disease and preterm birth: results of a pilot intervention study.

BACKGROUND: Previous case-control and prospective studies have shown an association between the presence of periodontitis and the risk of preterm birth (PTB). The goal of this pilot trial was to determine the feasibility of conducting a trial to determine whether treatment of periodontitis reduces the risk of spontaneous preterm birth (SPTB). METHODS: Three hundred sixty-six (366) women with periodontitis between 21 and 25 weeks' gestation were recruited and randomized to one of three treatment groups with stratification on the following two factors: 1) previous SPTB at <35 weeks and 2) body mass index <19.8 or bacterial vaginosis as assessed by Gram stain. The treatment groups consisted of: 1) dental prophylaxis plus placebo capsule; 2) scaling and root planing (SRP) plus placebo capsule; and 3) SRP plus metronidazole capsule (250 mg t.i.d. for one week). An additional group of 723 pregnant women meeting the same criteria for periodontitis and enrolled in a prospective study served as an untreated reference group. RESULTS: The rate of PTB at <35 weeks was 4.9% in the prophylaxis group, compared to 3.3% in the SRP plus metronidazole group and 0.8% in the SRP plus placebo group (P = 0.75 and 0.12, respectively). The rate of PTB at <35 weeks was 6.3% in the reference group. CONCLUSIONS: This trial indicates that performing SRP in pregnant women with periodontitis may reduce PTB in this population. Adjunctive metronidazole therapy did not improve pregnancy outcome. Larger trials will be needed to achieve statistical significance, especially at less than 35 weeks gestational age.

A randomized trial of intrapartum analgesia in women with severe preeclampsia.

OBJECTIVE: To estimate whether the cesarean delivery rate differs between women with severe preeclampsia who receive intrapartum epidural analgesia versus patient-controlled intravenous opioid analgesia. METHODS: Women with severe preeclampsia at at least 24 weeks' gestation were randomly assigned to receive either intrapartum epidural (n = 56) versus patient-controlled intravenous opioid analgesia (n = 60), and each was administered by a standardized protocol. The sample size was selected to have 80% power to detect at least a 50% difference in the predicted intergroup cesarean delivery rates. Data were analyzed by intent to treat. RESULTS: Selected maternal characteristics and neonatal outcomes were similar in the two groups. The cesarean delivery rates in the epidural group (18%) and the patient-controlled analgesia group (12%) were similar (P =.35). Women who received epidural analgesia were more likely to require ephedrine for the treatment of hypotension (9% versus 0%, P =.02), but their infants were less likely to require naloxone at delivery (9% versus 54%, P <.001). Epidural analgesia provided significantly better pain relief as determined by a visual analogue intrapartum pain score (P <.001) and a postpartum pain management survey (P =.002). CONCLUSION: Compared with patient-controlled intravenous opioid analgesia, intrapartum epidural analgesia did not significantly increase the cesarean delivery rate in women with severe preeclampsia at our level III center, and it provided superior pain relief.

Severe preeclampsia at <25 weeks of gestation: maternal and neonatal outcomes.

OBJECTIVE: The purpose of this study was to determine maternal and neonatal outcomes of women who were delivered because of severe preeclampsia before 25 weeks of gestation. STUDY DESIGN: We used a computerized database to identify 3800 women with preeclampsia among 35,937 deliveries from 1991 to 1997. Of these, 39 women (1%) with severe preeclampsia were delivered before 25 weeks of gestation. We abstracted outcomes in these women and their newborns. RESULTS: All 39 women had severe preeclampsia as defined by clinical and/or laboratory criteria. Thirty-three of the 39 women had severe-range hypertension. Twenty-one women (54%) experienced morbidity that included abruptio placentae (n = 5), HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome (n = 9), renal insufficiency (n = 5), and eclampsia (n = 3). No women required dialysis or intensive care unit admission, and none of the women died. All maternal morbidities reversed after delivery. Twenty-two infants (55%) were live-born. Only 4 infants (10%) survived, all with severe handicaps. CONCLUSION: In women with severe preeclampsia before 25 weeks of gestation, delivery is associated with minimal short-term maternal morbidities, although neonatal morbidity and death are appreciable.
