RESUMO
OBJECTIVE: The purpose of the study was to compare the body mass and fat compositions of menopausal women who were taking conventional doses of hormone replacement therapy (HRT) with that of menopausal women who were not taking any hormones. DESIGN: The body fat composition of 169 healthy postmenopausal women was measured using a noninvasive handheld machine, the Electrolipograph (BioAnalogics ELG, Beaverton, OR, USA). Impedance to electrical flow in tissues is lower with increasing water content of the tissue. Information on HRT, lifestyle, diet, smoking, and alcohol was obtained from the medical record and by a telephone interview before women were invited to participate. HRT and non-HRT groups were compared. Multivariate linear regression, which included age, years since menopause, type of menopause, and use of HRT, was performed for each of the two major outcomes: body mass index (BMI) and percentage of body fat. RESULTS: Comparisons between subgroups showed a large number of significant differences reflecting differences in age since menopause, baseline BMIs, and baseline waist to hip ratios. In the regression model, however, the only factor significantly associated with lower fat and BMI was the use of HRT. Women who were taking HRT had significantly lower percentages of body fat (-4.8%; p < 0.001) and BMI (-2.6 kg/m2; p < 0.001) compared with nonusers. Age and duration and type of menopause were not significant predictors of weight and BMI in this group of postmenopausal women. CONCLUSIONS: In this study, HRT seems to be associated with a significant reduction in postmenopausal weight and fat mass gains. This may be an important mechanism by which HRT exerts its beneficial long-term effects on cardiovascular health.

OBJECTIVE: To study the safety of oxytocin augmentation in patients having abnormal labors after a prior cesarean delivery. METHODS: We retrospectively analyzed a case series of women undergoing a trial of labor after a previous cesarean delivery from the University of California San Francisco perinatal data base. Women whose labors were augmented with oxytocin were compared to women with labor abnormalities managed without the use of oxytocin. A wide range of maternal and neonatal outcomes was compared. Only vertex singleton term deliveries were studied. RESULTS: From 1975-1990 there were 504 trials of labor, of which 185 (37%) had labor abnormalities; 62 of these 185 (34%) were augmented with oxytocin. Fifty-eight percent of the trials of labor ended in vaginal delivery. In patients since 1982, 73% delivered vaginally. Forty-six (74%) of augmented patients delivered vaginally. There were no maternal deaths, uterine ruptures, or hysterectomies. Estimated blood loss was slightly greater among augmented patients after controlling for mode of delivery (P < .05), but only by 50-100 mL on average. There was no difference in the need for maternal transfusion. Fetal trauma and fetal scalp blood sampling occurred more frequently (P < .05) in the augmented labors, but only in the subgroup delivered by cesarean. No increased risk was demonstrated by a comparison between patients receiving oxytocin and epidural anesthesia and patients with labor abnormalities receiving neither. CONCLUSION: Retrospective analysis supports the use of oxytocin and epidural anesthesia to augment abnormal trials of labor after prior cesarean.

OBJECTIVE: To examine the association of prolonged latent phase with cesarean risk, subsequent labor abnormalities, and other adverse maternal and neonatal outcomes. METHODS: Patients with prolonged latent phase were compared to patients with normal latent phase. We studied 10,979 singleton vertex deliveries of at least 37 weeks' gestation. Patients with risk factors for adverse outcome known before labor were excluded from the analysis. RESULTS: Seven hundred thirteen patients (6.5%) had prolonged latent phase. Subsequent labor abnormalities were more frequent among patients with prolonged latent phase (42.9 versus 16.3%; P < .05), as was cesarean delivery (24.4 versus 6.9%; P < .05). Need for neonatal resuscitation, thick meconium, maternal fever, low 5-minute Apgar score, intensive care nursery admission, lengthened maternal and newborn hospital stays, and higher estimated blood loss were all significantly more frequent in patients with prolonged latent phase after controlling for mode of delivery. Multivariate linear logistic regression models were created to determine whether these risks actually reflected the prolonged latent phase. The first model controlled for other labor abnormalities, parity, epidural use, and macrosomia and showed prolonged latent phase to be associated with an increased risk for cesarean delivery (relative risk [RR] 1.65, 95% confidence interval [CI] 1.32-2.06). The second model controlled for other labor abnormalities, postdates, thick meconium, mode of delivery, and prolonged rupture of membranes and showed that both the need for newborn resuscitation and 5-minute Apgar scores less than 7 were significantly more frequent in association with a prolonged latent phase (RR 1.37 and 1.97, 95% CI 1.15-1.64 and 1.23-3.16, respectively). CONCLUSIONS: Prolonged latent phase is independently associated with an increased incidence of subsequent labor abnormalities, need for cesarean delivery, depressed Apgar scores, and need for newborn resuscitation. The presence of prolonged latent phase should alert the clinician to an increased risk for further problems during the labor.

OBJECTIVE: To identify the relationship between maternal cigarette smoking and ultrasound-confirmed placenta previa. METHODS: A matched case-control design was used. Cases were drawn from the New England Medical Center and Cambridge Hospital from July 1992 through March 1994. Each case was delivered by cesarean after 24 weeks' gestation and had an antenatal ultrasound examination confirming placenta previa. Matched controls were obtained by requesting records on the first three deliveries by the referring provider the same month as the index case. Data on potential risk factors were drawn from the records of the initial prenatal visit, before previa was diagnosed. The data were analyzed with conditional logistic regression. RESULTS: Thirty-two cases of ultrasound-documented placenta previa were identified. A number of potential confounders were associated with previa: age (odds ratio [OR] 1.15, 95% confidence interval [CI] 1.05-1.26), gravidity (OR 1.4, 95% CI 1.1-1.7), parity (OR 1.4, 95% CI 1.1-1.9), prior spontaneous abortion (OR 3.1, 95% CI 1.3-7.4), prior elective abortion (OR 3.0, 95% CI 1.2-7.6), and prior cesarean delivery (OR 3.5, 95% CI 1.3-9.9). The crude OR for current smoking was 3.0 (95% CI 1.1-8.6). The OR for smoking ranged from 2.6-4.4, despite controlling for confounders. CONCLUSION: Current cigarette smoking is associated with a 2.6-4.4-fold increased risk of placenta previa.

OBJECTIVE: To determine the benefits of antenatal diagnoses of fetal aneuploidy in women who continued their pregnancies. METHODS: A questionnaire was mailed to 51 mothers of children with aneuploidy. Women whose fetuses were diagnosed prenatally comprised the study group and those whose infants were diagnosed at birth were controls. Outcomes measured included an assessment of pregnancy management, neonatal outcome, subjective measures of depression and anxiety, and evaluation of women's emotional and physical experience of the pregnancy. For outcomes measured by nonparametric survey questions, 20 women were needed in each arm to achieve a power of 80% to detect a 2-point difference on a 6-point scale; for our neonatal outcomes, 100 women were needed in each arm to achieve 80% power to detect a difference in length of stay (less than 1 week versus greater than 1 week) or need for surgery. RESULTS: Thirty-eight women (75%) responded. Most (86%) had children with trisomy 21. Seventeen women (45%) received their child's diagnosis at birth; 21 (55%) had prenatal diagnoses. Demographic measures were similar except that women with prenatal diagnoses attended religious services more frequently (1--3 times per month versus once to several times per year, P =.04). Women with prenatal diagnosis had better perceptions of their physical experience of pregnancy (median score of 10 versus 6 on a 10-point visual analog scale, P =.005) and their emotional experience of the birth (median score of 7.5 versus 2, P =.001). Mental Health Inventory scores were similar between groups. Neonates without prenatal diagnoses were more likely to be transferred to tertiary centers after birth (70% versus 24%, P =.004); lengths of hospital stays and need for surgery were similar. Seventy-one percent (95% confidence interval [CI] 48, 89%) of women with prenatal diagnoses said they would have done nothing differently in the pregnancy compared with 29% (95% CI 10, 56%) of women with diagnoses at birth. CONCLUSION: Early knowledge of fetal aneuploidy is beneficial to women who continue their pregnancies. These results might be useful when counseling women who do not intend to terminate abnormal pregnancies, but are considering prenatal diagnosis.

OBJECTIVE: To compare the morbidity of total abdominal hysterectomy and abdominal myomectomy in the surgical management of uterine leiomyomas. METHODS: Hospital records were reviewed for all women who underwent hysterectomy (n = 89) or myomectomy (n = 103) between May 1, 1988, and May 1, 1993, for the preoperative diagnosis of leiomyoma. RESULTS: There were significant differences between the two groups for average age (hysterectomy 39.2 years, myomectomy 34.4 years; mean difference 4.8, 95% confidence interval [CI] of difference 3.7-5.9), uterine size (hysterectomy 15.2, myomectomy 11.5 weeks; mean difference 3.8, 95% CI of difference 2.0-5.4) and use of a GnRH agonist (hysterectomy 23.6%, myomectomy 55.3%; relative risk [RR] 0.4, 95% CI 0.3-0.6). Myomectomy was associated with decreased estimated blood loss (hysterectomy 796 mL, myomectomy 464 mL; mean difference 331, 95% CI 121-542) and febrile morbidity (risk of temperature 38C or 48 or more hours postoperatively: for hysterectomy 49.4%, for myomectomy 32%; RR 1.5, 95% CI 1.1-2.2). Using multivariate linear regression, estimated blood loss was similar between the groups after controlling for uterine size. There was no difference in blood transfusion rates. There were two ureteral, one bladder, one bowel, and one femoral nerve injury in the hysterectomy group, and there were no intraoperative visceral injuries in the myomectomy group. CONCLUSION: Myomectomy compares favorably to hysterectomy in the surgical management of leiomyomas, with a possible decreased risk for visceral injury and infection.

OBJECTIVE: To define factors causing prolonged labor in nulliparous women undergoing active management of labor. METHODS: We included all nulliparas delivered during 1990-1994 with spontaneous onset of labor lasting more than 12 hours, singleton gestation, cephalic presentation, and labor at greater than 37 weeks. Each patient was matched with the next nulliparous woman who delivered with a labor lasting less than 12 hours and who fulfilled the same inclusion criteria. Subjects were managed according to the previously described active management of labor protocol from The National Maternity Hospital, Dublin. RESULTS: In the 5-year period, 9018 nulliparas met inclusion criteria, with 147 (1.6%) having prolonged labor. Prolonged labor was due to inefficient uterine action in 65%, persistent occipitoposterior position in 24%, and cephalopelvic disproportion in 11% of cases. Univariate analysis showed statistically significant (P < .05) differences in maternal body mass index, cervical dilation on admission, oxytocin use, epidural use, placement of epidural at less than 2 cm of dilation, and birth weight between these study groups. On multivariate conditional logistic regression analysis, the following were significant independent predictors for having a prolonged labor (odds ratios with 95% confidence intervals presented): 3.1 (1.3-7.3) for cervical dilation less than 2 cm on admission, 42.7 (7.5-242.0) for early epidural placement, 5.1 (1.9-13.7) for epidural placement at greater than or equal to 2 cm, and 10.2 (3.6-29.4) for birth weight greater than 4000 g. CONCLUSION: Less-advanced cervical dilation on admission and epidural use, especially when placed early, are strongly associated with prolonged labor.

OBJECTIVE: To compare the outcome of twin gestations complicated by a single anomalous fetus with twin gestations with no fetal anomalies. METHODS: The study included all patients with twin gestations diagnosed with a fetal anomaly in one fetus during 1990-1994, and excluded twin gestations with anomalies in both fetuses. The control twin group was composed of all other normal twin pregnancies followed and delivered at our center in the preceding 2 years. RESULTS: We reviewed 24 twin gestations with at least one anomalous fetus. Five cases were excluded because of anomalies in both fetuses, and a further five pregnancies had selective termination or termination of the entire pregnancy. There were 14 ongoing twin pregnancies with one anomalous fetus, and their median gestational age at diagnosis was 18 weeks (range 16-20). All twin anomalies were correctly diagnosed antenatally. Gestational age at delivery and birth weight were significantly lower for twins complicated by an anomaly compared with control twins (P = .008 and P = .001, respectively). The cesarean delivery and perinatal mortality rates of twin pregnancies with anomalies were significantly higher than those of normal twins (P = .01 and P < .001, respectively). CONCLUSION: The presence of a single anomalous fetus in a twin gestation significantly increases the risk of preterm delivery compared with nonanomalous twin gestations.

OBJECTIVE: To compare neonatal morbidity and mortality in a large cohort of triplet pregnancies with singleton and twin neonates managed at a single tertiary center over a short time. METHODS: Records from all triplet pregnancies managed and delivered from 1992 to 1996 were reviewed for neonatal outcome data. Pregnancies delivered before 20 weeks' gestation and neonates with lethal congenital anomalies were excluded. The comparison group comprised all singleton and twin neonates managed in the same neonatal intensive care unit (NICU) during the same period. RESULTS: During the 5-year period, 55 triplet pregnancies and their resulting 165 neonates were managed and delivered at this center. Their outcomes were compared with those of 959 singleton and 357 twin neonates born at similar gestational ages. The median gestational age at delivery for triplets was 32.1 weeks, and 149 of the 165 infants were admitted. Sixteen triplet neonates were not admitted to our neonatal intensive care unit, 12 because of previable gestational age, three because of stillbirth, and one because of a lethal congenital anomaly. The crude perinatal mortality rate in triplets was 121 per 1000 births, and there was no significant difference in outcome based on triplet birth order. There were no significant differences in survival rates between singleton, twin, and triplet neonates, with an overall neonatal survival of 95%, 95%, and 97%, respectively. The only significant differences in morbidity were an increased incidence of mild intraventricular hemorrhage (relative risk [RR] 6.20; 95% confidence interval [CI] 2.64, 14.61), mild retinopathy of prematurity (RR 20.05; 95% CI 3.59, 111.79), and severe retinopathy of prematurity (RR 46.69; 95% CI 6.25, 348.85) in triplets compared with singletons, and severe retinopathy of prematurity (RR 6.83; 95% CI 1.24, 37.56) in triplets compared with twins. CONCLUSION: When stratified by gestational age, triplet neonates delivered at 24-34 weeks' gestation have similar outcomes as singleton and twin neonates, with the only clinically significant difference being an increased incidence of retinopathy of prematurity in triplets.

This report suggests an alternative for dealing with the diagnostic dilemma of differentiating an ovarian pregnancy from a ruptured CL cyst and suggests a conservative management approach that will possibly minimize adhesion formation and optimize future fertility. This new approach is based on a single case reported here, and therefore needs further verification. However, use of this revised set of diagnostic criteria, combined with the judicious use of MTX, may be an alternative therapy for selected ovarian pregnancies.

OBJECTIVE: To test the hypothesis that elevated temperature is more common after abdominal myomectomy than after hysterectomy. DESIGN: Retrospective cohort study. SETTING: Academic medical center. PATIENT(S): One hundred one women who underwent abdominal myomectomy and 160 women who underwent total abdominal hysterectomy for benign disease from 1988-1993. INTERVENTION(S): Abdominal myomectomy. MAIN OUTCOME MEASURE(S): Temperature of > or = 38.5 degrees C within 48 hours after operation. RESULT(S): Although univariate analysis showed that the incidence of elevated temperature was slightly greater among patients who underwent myomectomy (33% versus 26%, relative risk 1.29, 95% confidence interval 0.88-1.90), multivariate logistic regression analysis showed a 3.29 relative risk of elevated temperature (95% confidence interval 1.56-6.96) with myomectomy after controlling for age, parity, estimated blood loss, and treatment by the general gynecology service. CONCLUSION(S): After controlling for confounders, myomectomy was found to be an independent predictor for fever in the first 48 hours after operation.

OBJECTIVE: To examine the effect of an intravenous (i.v.) fluid bolus on the amniotic fluid index (AFI) in patients with preterm ruptured membranes. METHODS: Nonlaboring patients at 24-37 weeks' gestation with documented ruptured membranes were randomized to either no hydration or to an i.v. fluid bolus with 1 L of normal saline administered over 30 minutes. All patients had a baseline AFI measured. The same blinded examiner repeated the examination 90 minutes later. RESULTS: Six patients were randomized to the hydration group, seven to the control group. The groups were similar in age, gravidity, parity, time since rupture, gestational age, and baseline AFI. In the hydration group, the AFI increased 5.1 cm (95% confidence interval [CI] 2.9-7.3) after the fluid bolus. In the no-hydration group, the change was 0.6 cm (95% CI-1.1 to 2.2). The difference in the change in AFI between groups was 4.5 cm (95% CI 1.3-7.7) (P = .008). CONCLUSION: The AFI is sensitive to maternal hydration in patients with preterm rupture of membranes and can be increased with an i.v. fluid bolus.

Left ventricular hypertrophy is associated with decreased longevity and often leads to congestive heart failure. An exploratory study of magnetic resonance imaging in human left ventricular hypertrophy was performed. First, 13 patients with left ventricular hypertrophy and 7 controls of similar ages were studied using electrocardiogramgated end-diastolic images. Visual inspection suggested that low-intensity zones were frequently found within the hypertrophied myocardium. To verify this observation, the images were processed with semi-automatic edge detection and a derivative-based tissue characterization algorithm, yielding tissue heterogeneity indices (THI-A and THI-V) which objectively measured the low-intensity zones. THI-A and THI-V were both significantly greater in left ventricular hypertrophy patients than in controls (THI-A: 0.111 vs 0.038, p = 0.009). THI was also significantly correlated with duration of disease and electrocardiographic abnormalities. To validate these initial findings prospectively, the same quantitative analysis was applied to magnetic resonance images of an additional 20 left ventricular hypertrophy patients and 12 controls from two institutions, using different imaging systems and different acquisition parameters. Again, THI was significantly greater in patients than in controls. Analysis of end-systolic images yielded similar results. In four dogs with left ventricular hypertrophy induced by aortic banding, THI showed a statistically significant increase as left ventricular hypertrophy developed. Hypertrophied myocardium thus shows reproducible differences from normal tissue with magnetic resonance imaging; hence, quantitative magnetic resonance tissue characterization may be useful in assessing pathologic changes in LVH.

OBJECTIVE: To determine whether suture closure of subcutaneous dead space decreases wound disruption after Cesarean delivery. METHODS: All patients undergoing Cesarean delivery at the New England Medical Center from September 1995 to June 1997 were eligible. One group (162 patients) was randomly assigned to have the subcutaneous fat layer closed with a running 3-0 plain suture. The other group (165 patients) had this layer left unclosed. Both groups had careful hemostasis of this layer with cautery and copious irrigation. All laboring and ruptured patients received prophylactic antibiotics. The patients were followed for 6 weeks after delivery for wound disruption. RESULTS: No significant differences were noted between the two groups with respect to demographic, obstetric, or surgical characteristics or loss to follow-up. Excluding those lost to follow-up (27 closed vs. 22 unclosed), there was no difference in wound infection (11 (8.1%) closed vs. 13 (9.1%) unclosed, RR 0.90, 95% CI 0.14, 2.08). There were decreases in risk of skin separation (three (2.2%) vs. six (4.2%), RR 0.53, 95% CI 0.42, 1.93) and seroma or hematoma formation (two (1.5%) vs. seven (4.9%), RR 0.30, 95% CI 0.06, 1.43) that were not statistically significant. Decreases that were not statistically significant were also noted for any wound disruption (14 (10.4%) vs. 21 (14.7%), RR 0.71, 95% CI 0.37, 1.33) and non-infected wound complication (three (2.2%) vs. eight (5.6%), RR 0.40, 95% CI 0.11, 1.47). Increasing gravidity and parity, and Cesarean delivery performed for failure to progress were independent risk factors for any wound complication. Controlling for these factors did not alter the effect of subcutaneous closure. CONCLUSIONS: Closure of the subcutaneous space does not increase and may protect against wound complications in patients undergoing Cesarean delivery.

Previously reported cases of spontaneous rupture of the kidney or ureter reflect underlying renal pathology and have been reported both spontaneously and in relationship to delivery, but not in relation to other operative procedures. A 27-year-old woman at 19 weeks' gestation developed severe right flank pain in the operating room immediately prior to cerclage placement. Postoperative renal ultrasound examination and intravenous pyelogram performed to evaluate persistent flank pain demonstrated renal pelvis rupture. No other renal abnormality was present. We postulated that increased urine flow from the fluid bolus for the spinal anesthetic precipitated the rupture.

OBJECTIVE: The purpose of this study was to evaluate the use of the TDx-FLM fluorescence polarization assay on vaginal pool fluid in patients with preterm premature rupture of membranes (PPROM). METHODS: A prospective matched-pairs study was performed at a tertiary care center. For each patient enrolled, amniotic fluid samples were obtained by sterile speculum examination and by amniocentesis within 12 h of each other. Inclusion criteria were the presence of PPROM and a gestational age of 30-36 weeks. The samples were analyzed separately using the TDx-FLM assay in the same laboratory. The results were compared using a paired Student t test. RESULTS: A total of 16 patients received both amniocentesis and vaginal collection of amniotic fluid. The mean gestational age at amniocentesis was 33.3 weeks (SD 1.9). In every case, the vaginal pool TDx-FLM result was lower than the amniocentesis result. The mean difference in the assays between the two fluid sources was 35% (range 17-63%, p < 0.001). Amniocentesis suggested a mature result in 12 cases (75%), an indeterminate result in two cases (12.5%), and an immature result in two cases (12.5%). Vaginal pool fluid suggested a mature result in four cases (25%), an indeterminate result in nine cases (56%), and an immature result in three cases (19%). Using the cut-off values validated for amniocentesis specimens as a standard for comparison, vaginal pool TDx-FLM assay had 42% sensitivity, 100% specificity, 100% positive predictive value and 36% negative predictive value for predicting lung maturity. CONCLUSIONS: The TDx-FLM assay on vaginal pool samples of amniotic fluid yielded results that were significantly different from those of amniocentesis samples. At this point, the assay is only clinically useful for vaginal pool samples when a mature result is obtained.

We examined the relation with birth weight and umbilical cord blood concentrations of haematopoietic stem and progenitor populations in 288 singleton infants. Across the whole range of birth weight, there was a positive relation between birth weight and CD34+CD38(-) cells, with each 500 g increase in birth weight being associated with a 15.5% higher (95% confidence interval: 1.6-31.3%) cell concentration. CD34+ and CD34+c-kit+ cells had J-shaped relations and CFU-GM cells had a U-shaped relation with birth weight. Among newborns with >or=3000 g birth weights, concentrations of these cells increased with birth weight, while those below 3000 g had higher stem cell concentrations than the reference category of 3000-3499 g. Adjustment for cord blood plasma insulin-like growth factor-1 levels weakened the stem and progenitor cell-birth weight associations. The positive associations between birth weight and stem cell measurements for term newborns with a normal-to-high birth weight support the stem cell burden hypothesis of cancer risk.

Obsessive-compulsive disorder (OCD) is a well-recognized psychiatric disorder often beginning in reproductive age. A case of OCD in pregnancy is presented and its management discussed. A 28-year-old G3P2 woman presented at 8 weeks' gestation for prenatal care. She had been diagnosed with OCD following her prior pregnancy. Her symptoms primarily involved obsessions about infectious disease and compulsive cleaning and organization of household items, both of which greatly distressed her and interfered with caring for her children. She had been managed with clomipramine between pregnancies and was beginning a clinical trial of fluvoxamine when pregnancy was diagnosed. She discontinued medication when she realized she was pregnant. Her symptoms were managed during the pregnancy with frequent appointments with her obstetrician and her psychiatrist. She used a behavioral technique, "thought-stopping", as well. Her symptoms worsened in the last month of pregnancy and immediately after delivery; she delivered a normal infant. The clomipramine was restarted postpartum. She has done well since then, with minimal psychiatric symptoms. OCD is a disabling psychiatric disorder that occurs in women of reproductive age. With careful management, pregnancy without disabling psychiatric symptoms can occur.

OBJECTIVE: Our purpose was to describe the total costs involved in the delivery, prenatal, and neonatal care for triplet pregnancies. STUDY DESIGN: Twenty triplet pregnancies were born at our institution over the 1-year period between July 1, 1992, and June 30, 1993. Total charges for prenatal care, physician fees, antepartum admissions, delivery, postpartum inpatient and outpatient care, and neonatal inpatient and outpatient care were extracted from the hospital billing computers. RESULTS: Our 20 triplet pregnancies were delivered of 54 live born infants at an average gestation of 30.2 weeks. Mothers averaged 16.7 inpatient hospital days. Total cost of prenatal care, outpatient laboratories and ultrasonography, delivery, and maternal inpatient care averaged $27,491. Neonates averaged 13.7 hospital days. Total neonatal costs for the inpatient stay and short term-postpartum (< 6 week) outpatient period was $36,856 per family. Total average cost per family was $64,347. CONCLUSION: Combined maternal and neonatal costs per individual baby delivered was approximately $21,000. Although expensive, this cost is far from prohibitive, even in times of close attention to health care expenditures.

OBJECTIVE: We performed a meta-analysis to examine the role of antibiotic prophylaxis in preventing postoperative infections among nonlaboring women undergoing cesarean delivery with intact membranes. STUDY DESIGN: A computerized literature search was performed with MEDLINE. Studies were included if they contained data on patients undergoing cesarean delivery in the absence of labor and ruptured membranes. Only randomized trials with a placebo control group were included. RESULTS: Seven studies were found. Use of antibiotics decreased the risk of all infectious outcomes reported. When the results of 4 studies were pooled, prophylactic antibiotic use was associated with a significant reduction in postoperative fever (relative risk, 0.25; 95% confidence interval, 0.14-0.44). A similar reduction was noted for endometritis in 4 studies (relative risk, 0.05; 95% confidence interval, 0.01-0.38). Two studies reported on wound infection and showed a trend toward a protective effect (relative risk, 0.59; 95% confidence interval, 0.24-1.45). CONCLUSION: The prophylactic use of antibiotics reduces the risk of postoperative infectious complications after cesarean delivery even in the population at lowest risk.
