Supine versus Prone Position during Delayed Cord Clamping in Infants ≥36 Weeks: A Randomized Trial.

OBJECTIVE: There is no recommendation in the literature on optimal positioning of the newborn immediately at birth during delayed cord clamping. To evaluate if prone positioning on the mother's chest at birth during delayed cord clamping leads to a higher hematocrit at 30 hours of life compared to supine positioning. STUDY DESIGN: A randomized unblinded trial comparing prone and supine position of the newborn before umbilical cord clamping. Healthy newborns ≥36 weeks gestational age and born vaginally with cephalic presentation were included. The newborn was randomized to prone or supine position. Umbilical cord clamping was delayed in both groups to 1 minute after birth. The primary outcome was hematocrit at 30 hours of life. As a secondary outcome, cerebral tissue oxygenation (CrSO2) values were compared between both groups by near infrared spectroscopy. RESULTS: There was no difference in hematocrit at 30 hours of life between supine and prone positions with a mean at 52 and 53.1, respectively, mean difference -1.1 (95% confidence interval:-2.7, 0.5), p = 0.17. Newborns in supine and prone positions had comparable level of CrSO2 at 30 hours of life with a mean at 84.1 and 82.2, respectively, mean difference 1.9 (-0.2, 4.0), p = 0.07. There was no correlation between hematocrit and CrSO2 at 30 hours of life (r = 0.14). CONCLUSION: There was no difference between prone and supine positioning immediately after birth during delayed cord clamping on hematocrit at 30 hours of life. In the absence of clear findings, further studies with assessment of the effect of position on breastfeeding success in the case room, on maternal satisfaction and outcome beyond 30 hours are needed to make adequate recommendations on positioning. KEY POINTS: · Delayed cord clamping at 60 seconds is recommended at birth, but optimal positioning is unknown.. · A randomized trial was conducted to compare hematocrit at 36 hours of life of prone versus supine position.. · No difference in hematocrit was found in prone versus supine position during delayed cord clamping..

Evaluation of a clinical protocol for the management of fever in labor among pregnant women at term: A quality-improvement study.

OBJECTIVE: To assess the impact of a quality-improvement initiative designed to increase diagnostic accuracy and adequate management of clinical chorioamnionitis (CC) at a tertiary center. Chorioamnionitis occurs in 1%-13% of term pregnancies and increases maternal and neonatal peripartum complications; often over-diagnosed, it leads to unnecessary investigations and treatments. METHODS: This was an interrupted time-series study. In September 2017 two interventions were implemented: (1) staff training and (2) standardized clinical protocol for the management of fever in labor. All singleton term pregnancies were included. CC cases were reviewed in the pre-intervention (2015-2016, n = 179) and post-intervention (2017-2018, n = 142) groups. CC criteria based on the American College of Obstetricians and Gynecologists guidelines, antibiotics, maternal and neonatal outcomes, and pathology were compared. A cost-consequence analysis was performed. RESULTS: Incidence of CC decreased from 8.2 to 5.6 per 10 person-year (P < 0.001). This was associated with a significant increase in diagnostic accuracy from 15.7% to 73.2% (P < 0.001). Weight-adjusted tobramycin dosage improved from 8.8% to 69.1% (P < 0.001). Maternal length of hospitalization and readmissions decreased significantly, without affecting neonatal sepsis rate. Interventions decreased yearly hospital costs associated with CC by 23.4%. CONCLUSION: Standardizing the management of fever in labor significantly increased the diagnostic accuracy of CC and decreased the misuse of antibiotics in term pregnancies. CC costs decreased by 23.4%.

Uterine Exteriorization Compared With In Situ Repair of Hysterotomy After Cesarean Delivery: A Randomized Controlled Trial.

OBJECTIVE: To compare the effect of exteriorized with in situ uterine repair on intraoperative nausea and vomiting during elective cesarean delivery under spinal anesthesia using a phenylephrine infusion. METHODS: This study was a randomized double-blinded controlled trial of 180 women undergoing elective cesarean delivery using a standardized anesthetic protocol. Patients were randomized to exteriorization (n=90) or in situ uterine repair (n=90). The spinal anesthetic, phenylephrine infusion, and blood pressure management were all standardized. The primary outcome was postdelivery intraoperative nausea and vomiting using a 4-point scale (0-3). A sample size of 80 patients per group was needed to demonstrate a 50% reduction in intraoperative nausea and vomiting with in situ repair. RESULTS: From November 2015 through July 2018, 180 patients were enrolled. Incidence of postdelivery intraoperative nausea and vomiting was 39% in the exteriorization group compared with 22% in the in situ group (P=.01). Incidence of hypotension (80% vs 50%; P<.001) and tachycardia (33% vs 17%; P=.02) was significantly higher in the exteriorization group, and more phenylephrine boluses were administered to this group (median 4 boluses [first and third quartiles 1.25-7] vs 2 [0-4]; P<.001). The duration of surgery, blood loss, and postoperative hemoglobin decline were similar between groups. CONCLUSION: In situ uterine repair for elective cesarean delivery under spinal anesthesia with a phenylephrine infusion is associated with less postdelivery intraoperative nausea and vomiting.
