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 \u22651,000\u2009mL), 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.<\/jats:p><jats:p>\n            Results\u2003Of 1,268 women with an intrauterine pressure catheter, 298 (23.5%) also had an amnioinfusion. 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\u2009=\u20090.12, aOR 0.69; 95% CI 0.39\u20131.21), as well as secondary outcomes such as postpartum endometritis (3.0 vs. 2.5%, crude p\u2009=\u20090.61, aOR 1.12; 95% CI 0.49\u20132.53), postpartum hemorrhage (16.1 vs. 15.8%, crude p\u2009=\u20090.89, aOR 1.07; 95% CI 0.75\u20131.54), blood loss (479.5 vs. 500\u2009mL, adjusted p\u2009=\u20090.89), and cesarean delivery (40.6 vs.
