Abstract: Objective To investigate the in?uence of different latent period on perinatal outcomes in term prematur rupture of membrane (PROM). Methods From January 2013 to March 2016, 912 cases of pregnancy women with term PROM hospitalized in Department of Gynecology & Obstetrics, PLA Army General Hospital, were included. According to the time interval from PROM to labor, they were divided into latent period ≥ 24 h group (57 cases) and ﹤ 24 h group (855 cases), latent period ≥ 12 h group (233 cases) and ﹤12 h group (679 cases). The basic situation, cesarean section rate and perinatal outcomes of these groups were compared. Chi-square and t test were used for statistical analysis. Results There was no signi?cant difference on the age of pregnant women, delivery times, abortion times, gestational age at delivery and amniotic ?uid index between latent period ≥ 24 h group and ﹤ 24 h group, between latent period ≥ 12 h group and ﹤ 12 h group (all P ﹥ 0.05). The cesarean section rate of latent period ≥ 24 h group and ﹤24 h group was respectively 66.7%(38/57) and 44.7 (382/855), the proportion of puerperal infection wasrespectively 8.8% (5/57) and 2.8 (24/855), and the proportion of postpartum hemorrhage was respectively 19.3% (11/57) and 8.8 (75/855). The above indicators of latent period ≥ 24 h group were higher than that of ﹤ 24 h with statistical signi?cance (χ2=10.399, 4.390 and 6.933, respectively, all P ﹤ 0.05); but the incidence of fetal distress and neonatal pneumonia of two groups were no statistical difference (both P ﹥0.05). The cesarean section rate of latent period ≥ 12 h group was higher than that of ﹤ 12 h group［(58.4%, 136/233) vs (41.8%, 284/679)］, and there was significant difference (χ2=19.109，P=0.000). But the incidence of puerperal infection, postpartum hemorrhage, fetal distress, and neonatal pneumonia between two groups were no statistical difference (all P ﹥ 0.05). Conclusions For the term PROM, the risk of cesarean delivery significantly increases when latent period ≥ 12 h, and the risk of cesarean delivery, puerperal infection and postpartum hemorrhage signi?cantly increases when latent period ≥ 24 h.
