Women who had amnioinfusion through an intrauterine pressure catheter compared with those who had intrauterine pressure catheter alone had similar rates of intraamniotic infection (5.4 vs. 8.0%, crude p = 0.12, aOR 0.69; 95% CI 0.39-1.21), as well as secondary outcomes such as postpartum endometritis (3.0 vs. 2.5%, crude p = 0.61, aOR 1.12; 95% CI 0.49-2.53), postpartum hemorrhage (16.1 vs. 15.8%, crude p = 0.89, aOR 1.07; 95% CI 0.75-1.54), blood loss (479.5 vs. 500 mL, adjusted p = 0.89), and cesarean delivery (40.6 vs. 43.1%, crude p = 0.45, aOR 0.90; 95% CI 0.68-1.19).STUDY DESIGN: This was a retrospective cohort study of all women who had an intrauterine pressure catheter placement during labor at a tertiary referral hospital from January 2016 to June 2018. Outcomes were compared between women who had an intrauterine pressure catheter with amnioinfusion and intrauterine pressure catheter placement alone. The primary outcome was the rate of intraamniotic infection. Secondary outcomes included postpartum endometritis, postpartum hemorrhage (blood loss of >=1,000 mL), quantitative blood loss (mL), and cesarean delivery. Multivariable logistic regression analysis was performed to calculate adjusted odds ratios (aOR) and 95% confidence interval (95% CI), controlling for age, race, body mass index, gestational age, and length of time of rupture of membranes.All authors: DiSciullo A, Iqbal SN, Kawakita T, Mokhtari N, Wang TOriginally published: American Journal of Perinatology. 2020 Aug 13Fiscal year: FY2021Digital Object Identifier: ORCID: Date added to catalog: 2020-09-02
