目的　探讨早产合并胎膜早破潜伏期长短、分娩方式对新生儿的影响。方法　对 2 0 0 0年 1月至 2 0 0 2年 1 2月佛山市第一医院对 1 34例孕 2 8～ 36 + 6周早产合并胎膜早破单活胎新生儿进行回顾性分析 ,对潜伏期≤2 4h及 >2 4h新生儿的并发症进行对比。结果　潜伏期≤ 2 4h呼吸窘迫综合征 (RDS)明显高出潜伏期 >2 4h组(P <0 0 1 ) ,新生儿感染则潜伏期 >2 4h较潜伏期≤ 2 4h组高 (P <0 0 1 )。而剖宫产、阴道助产及阴道分娩出现新生儿并发症三者比较无统计学意义 (P >0 0 5 )。结论　随破膜时间延长新生儿RDS发生减少 ,但新生儿感染机会增加。不同分娩方式对新生儿结局无影响。 Objective To investigate the effects of premature rupture of membranes on the latent period of premature rupture of membranes and the mode of delivery on neonates. Methods From January 2000 to January 2012, Foshan City First Hospital, a retrospective analysis of 1 34 cases of neonates with premature rupture of membranes from 28 to 36 + 6 weeks pregnant with premature rupture of membranes , Comparisons of neonatal complications with latency <24 h and> 24 h. Results The latent period ≤ 24 h was significantly higher than that of the latent period> 24 h (P <0.01), while the latent period of neonatal infection was> 24 h compared with that of the latent period ≤ 24 h (P <0.01) . The cesarean section, vaginal delivery and vaginal delivery of neonatal complications were no statistically significant (P> 0.05). Conclusion With the prolonged rupture of membranes RDS occurred in neonates decreased, but the chance of neonatal infection increased. Different modes of delivery had no effect on neonatal outcome.
