Abstract:
Objective To investigate the incidence and pregnancy outcomes of premature rupture of membranes (PROM) in pregnant women in Beijing.Methods A retrospective multicenter study of 18 534 cases delivered in Beijing Obstetrics and Gynecology Hospital,Beijing Friendship Hospital,Daxing MCH Hospital and Tongzhou MCH Hospital from January 2011 to December 2011,was conducted.Results Among 18 534 cases,PROM occurred in 4 504 cases (24.30％),including 3 910 cases of in term PROM (21.10％) and 594 cases of preterm PROM (3.20％).The incidence of premature delivery was 6.17％ (1 144/18 534),and among 1 144 cases of premature delivery 547 cases were PROM (47.81％);the incidence of PROM was 22.75％ (3 957/17 390) in term delivery.The overall cesarean section (CS) rate was 48.50％ (8 989/18 534) and that in pregnant women with PROM was 35.55％ (1 601/4 504),but the CS rate in pregnant women without PROM was 52.66％ (7 388/14 030).The rate of postpartum hemorrhage was 13.12％ (210/1 601)in CS cases and 4.17％ (121/2 903) in vaginal delivery cases (x2 =121.361,P=0.000).The mean hospital stay for PROM was (5.3±2.9) d in CS cases and (4.3±2.3) d in vaginal delivery cases (t =-12.136,P =0.000).Conclusions Without severe maternal or fetal complications,the incidence of PROM is relatively high in Beijing region and PROM may not increase the maternal or fetal complications.Vaginal delivery is the main mode of delivery for PROM.Cesarean section may not cause less neonatal complications,but may lead to more postpartum hemorrhage and longer hospital stay.
