Abstract Objective To study the influence of premature rupture of membranes (PROM) on the early prognosis of extremely premature infants, and to provide a basis for the management of extremely premature infants and prenatal consultation. Methods A total of 179 extremely premature singleton infants who were born from 2017 to 2019 were enrolled. According to the presence or absence of PROM, they were divided into two groups: PROM group (n=69) and non-PROM group (n=110). A statistical analysis was performed for maternal data and early prognostic indicators. Results Compared with the non-PROM group, the PROM group had significantly higher incidence rates of earlyonset sepsis and necrotizing enterocolitis (NEC) (P < 0.05) and significantly lower rate of use of pulmonary surfactant and incidence rate of hemodynamically significant patent ductus arteriosus (P < 0.05). The multivariate logistic regression analysis showed that chorioamnionitis was an independent risk factor for early-onset sepsis and NEC (OR=11.062 and 9.437 respectively, P < 0.05), and PROM was an independent protective factor against the use of pulmonary surfactant (OR=0.363, P < 0.05). Conclusions PROM increases the incidence rates of early-onset sepsis and NEC in extremely premature infants and does not increase the incidence rates of other adverse outcomes. For pregnant women with PROM at the risk of extremely preterm delivery, prevention of miscarriage and chorioamnionitis is recommended to prolong gestational weeks, reduce the incidence rate of infection, and thus improve the outcome of extremely premature infants.
