Oxytocin protocols are employed to induce uterine contractions and progressive cervical changes, but they are associated with adverse maternal and neonatal outcomes. The aim of this study was to determine whether compliance with a checklist-based protocol for oxytocin administration was associated with changes in neonatal and maternal outcomes.A retrospective cohort study of 86,786 pregnant women undergoing term (37 weeks) induction of labor between January 2015 and December 2017 was performed. Systemwide training in the use of an oxytocin administration protocol was provided to obstetricians and nurses. Pre-use and in-use oxytocin checklists were incorporated into each unit's policies and procedures. Subsequently, charts were reviewed and individually audited by an obstetric nurse who scored each record based on the documentation of variables in an oxytocin administration protocol and ranked adherence as complete or absent. Primary outcomes were postpartum hemorrhage, neonatal ICU (NICU) admission, and delivery by cesarean section. Bivariate analyses (t-tests) were performed on adherent and nonadherent groups for comparison of selected demographic variables and the primary outcome variables. Logistic regression was completed on the primary outcome variable with eight covariates.Among patients with complete adherence to the oxytocin administration protocol, the rate of cesarean section in the unadjusted analysis was 16.20%, compared to 18.54% for those with incomplete adherence; the rates of postpartum hemorrhage were 2.64% vs. 3.14%, respectively, and the rates of NICU admission were 3.03% vs. 3.86%, respectively. In the multivariable logistic regression, complete protocol adherence was associated with significantly lower odds of postpartum hemorrhage (adjusted odds ratio [OR] 0.85, 95% confidence interval [CI] 0.76-0.94) but higher odds of Cesarean section (adjusted OR 1.07, 95% CI 1.01-1.13); the adjusted OR for NICU admission was 0.90, which did not reach statistical significance (95% CI 0.81-1.00). Among the covariates, nulliparity and elective induction were the strongest predictors of the primary outcomes of cesarean section, postpartum hemorrhage, and NICU admission.Adherence to the oxytocin administration protocol was associated with a decrease in postpartum hemorrhage but an increased risk of delivery by cesarean section.

Objective The purpose of this study was to examine the efficacy of specific protocols that have been developed in response to a previous analysis of maternal deaths in a large hospital system. We also analyzed the theoretic impact of an ideal system of maternal triage and transport on maternal deaths and the relative performance of cause of death determination from chart review compared with a review of discharge coding data. Study Design We conducted a retrospective evaluation of maternal deaths from 2007-2012 after the introduction of disease-specific protocols that were based on 2000-2006 data. Results Our maternal mortality rate was 6.4 of 100,000 births in just >1.2 million deliveries. A policy of universal use of pneumatic compression devices for all women who underwent cesarean delivery resulted in a decrease in postoperative pulmonary embolism deaths from 7 of 458,097 cesarean births to 1 of 465,880 births ( P = .038). A policy that involved automatic and rapid antihypertensive therapy for defined blood pressure thresholds eliminated deaths from in-hospital intracranial hemorrhage and reduced overall deaths from preeclampsia from 15-3 ( P = .02.) From 1-3 deaths were related causally to cesarean delivery. Only 7% of deaths were potentially preventable with an ideal system of admission triage and transport. Cause of death analysis with the use of discharge coding data was correct in 52% of cases. Conclusion Disease-specific protocols are beneficial in the reduction of maternal death because of hypertensive disease and postoperative pulmonary embolism. From 2-6 women die annually in the United States because of cesarean delivery itself. A reduction in deaths from postpartum hemorrhage should be the priority for maternal death prevention efforts in coming years in the United States.

Objective: The purpose of the present investigation was to analyze the effets of zidovudine on the postimplantation embryo and fetus.Methods: Pregnant Sprague-Dawley rats were given various doses (10 mg/kg, 30 mg/kg, 150 mg/kg) of zidovudine or saline by an endotracheal tube during the period of embryogenesis (days 6–8, 9–11, 6–11 postconception). The animals were sacrificed on days 18–19 of pregnancy, and their fetuses were removed by hysterotomy. Autopsies under low (15×) and high (40×) power light microscopy were performed on all fetuses.Results: There was no statistically significant difference among the groups with respect to maternal weight gain. There were more pregnancy resorptions in the group receiving high-dose zidovudine (150 mg/kg/day) throughout embryogenesis than in the control group (P = 0.001, respectively). Four major structural anomalies were noted among the 689 fetuses examined, but zidovudine was not associated with an increased frequency of congenital anomalies in rats when it was administered in doses similar to, 3-, and 15-fold higher than the regimen recommended for adult humans. The drug, however, was embryocidal in the high-dose group (P = 0.002).Conclusions: These findings are consistent with previous studies of preimplantation mouse embryos that demonstrated an embryocidal effect on preimplantation conceptuses. In summary, post-implantation embryonic zidovudine exposure was associated with significantly increased pregnancy losses (resorptions and intrauterine deaths).

Objective: Unexplained maternal serum α-fetoprotein elevation has been associated with an increased risk of intrauterine growth retardation, preterm delivery, and intrauterine fetal death. The purpose of this study was to determine whether patients with evidence of recent fetomaternal bleeding as a cause of elevated maternal serum α-fetoprotein level are at a lower risk for adverse pregnancy outcome than those without such evidence. Study Design: Patients with elevated maternal serum α-fetoprotein levels who had a singleton viable fetus without ultrasonographically detectable anomalies were offered inclusion in this study. Study participants had blood drawn for fetal cell analysis before amniocentesis. The pregnancy outcomes of patients with evidence of fetomaternal bleeding were compared with those of patients without. Results: Of 229 patients, 109 (47.6%) had evidence of fetomaternal bleeding as a possible cause of elevated maternal serum α-fetoprotein. Of these, 86 (78.9%) had a normal pregnancy outcome compared with 84 of 120 (70.0%) with a negative stain for fetal cells (p not significant). There was no significant difference in the incidence of preterm delivery (14 [12.8%] vs 15 [12.5%]), intrauterine growth retardation (5 [4.6%] vs 9 [7.5%]), or intrauterine fetal death (4 [3.7%] vs 8 [6.6%]) when patients with a positive stain for fetal cells were compared with those with a negative stain. Conclusion: Among patients with elevated maternal serum α-fetoprotein levels, those with evidence of recent fetomaternal bleeding do not appear to be at decreased risk for adverse pregnancy outcome compared with those without such evidence.

Objective:The purpose of this study was to evaluate the Equate Strep B® test for clinical use in patients at high risk for complications from group B streptococcus (GBS) disease.Methods:Vaginoperineal swabs were obtained from patients with preterm premature rupture of the membranes and/or preterm labor and semiquantitative GBS cultures and Equate® assay were performed.Results:From May 14, 1990, to April 30, 1992, 650 patients were enrolled; 626 had both culture and Equate® results available, of whom 24% were colonized with GBS. The sensitivity, specificity, positive predictive value, and negative predictive value of the rapid assay were 28%, 84%, 35%, and 79%, respectively. Although the prevalence of GBS was higher in patients with ruptured membranes compared with those with intact membranes, rupture of membranes did not affect test sensitivity or specificity.Conclusions:We conclude that the Equate® rapid assay is not a sensitive method of GBS detection in high-risk patients.

Although the administration of prophylactic antibodies for intrauterine transfusion is controversial, little information is available regarding placental transfer of antibiotics administered to the mother, or whether the presence of hydrops affects this placental transfer. Sixteen intravascular intrauterine transfusions were performed in 10 patients. Seven (10 procedures) patients were given 2 gm of cefazolin before the procedure and samples were obtained by fetal vascular access. Three patients (six procedures) were given 4 gm of piperacillin and samples were similarly obtained. Specimens were obtained for fetal serum, maternal serum, and amniotic fluid antibiotic concentration. The mean serum cefazolin concentration in hydropic fetuses was 18.04 +/- 3.37 micrograms/ml, and in nonhydropic fetuses the concentration was 21.02 +/- 17.8 micrograms/ml (p = 0.72). The mean fetal serum concentration of piperacillin was 22 +/- 12 micrograms/ml. The placental transfer of both drugs was similar. We conclude that the transplacental passage of these antibiotics is prompt and that the presence of hydrops does not significantly impair the passage of cefazolin.

The diagnosis of congenital syphilis is difficult, particularly in stillborn fetuses, who are often macerated and have undergone autolysis. These changes can obscure both syphilitic histologic findings and special stains for spirochetes in tissue specimens used to confirm the diagnosis of congenital syphilis. Five gravidas with untreated syphilis and fetal deaths underwent sonographic examination and amniocentesis. In all five cases, dark-field microscopic examination of the amniotic fluid showed spirochetes with morphology and motility characteristic of Treponema pallidum. Organisms were infrequent, but easily identified at 400x magnification and confirmed using an oil-immersion objective yielding a 900x magnification. After delivery, fetal-placental examination and autopsy showed clinical findings typical of congenital syphilis in all five cases. Histologic changes compatible with syphilis were found in all four autopsied fetuses. Silver impregnation stains were positive in two of five tissue specimens, and anti-treponemal monoclonal antibody immunofluorescence assays were positive in one of three amniotic fluid specimens examined retrospectively, further strengthening the specificity of the dark-field microscopic identification of spirochetes. This technique, which can make the diagnosis of congenital syphilis, is recommended for women with syphilis and a fetal death, especially if sonographic hydrops and/or edema is present or if an autopsy will not be performed.

OBJECTIVE: We describe changes in T-lymphocyte subpopulations in pregnancies complicated by human immunodeficiency virus infection. STUDY DESIGN: T-lymphocyte counts were performed every trimester and postpartum on all patients with human immunodeficiency virus infection. Patients with a CD4 count 3 were offered zidovudine after the first trimester. We performed a regression analysis of repeated measures on the total lymphocyte, CD4, and CD8 counts. RESULTS: Twenty-three patients were studied, 10 (43%) of whom took zidovudine. CD4, CD8, and total lymphocyte counts decreased in patients not taking zidovudine but remained stable in patients receiving zidovudine. The differences were not statistically significant. CONCLUSIONS: CD4 and CD8 counts may decrease during pregnancies complicated by human immunodeficiency virus infection, primarily because of decreases in the total lymphocyte count. The use of zidovudine may prevent this decline. The clinical use of absolute CD4 counts during pregnancy requires further study. (AM J OBSTET GYNECOL 1992;167:1575-9.)
