早产胎膜早破的临床分析

目的:探讨早产胎膜早破(pretermprematureruptureofmembranes,PPROM)的妊娠结局。方法:对70例PPROM进行回顾性分析。结果:70例PPROM的潜伏期为1~216·33h,平均48·33h。65·71%的PPROM有易发因素存在。孕28~33周与孕34~37周间PPROM分娩方式的比较,差异有显著性的意义(P<0·01)。孕28~33周PPROM新生儿发病率和死亡率明显高于孕34~37周者(P<0·01)。结论:对于孕周小者,尽量延长孕周至34周以上,以降低新生儿发病率和死亡率,尤其对于孕28~33周PPROM宜采取期待疗法,以减少新生儿合并症的发生。

Clinical analysis of pregnancy outcomes on preterm premature rupture of membranes

Objective:To study pregnancy outcome on preterm premature rupture of membranes (PPROM).Methods:70 cases of PPROM were retrospectively analyzed.Results:The average of latent periods on PPROM was 48 hours and 20 minutes. 65.71% of PPROM had predisposing factors. There was significantly differences in delivery way in patients between at 28~33 weeks' gestation and at 33~37 weeks' gestation (P<0.01).Neonatal morbidity and mortality were higher in patients at 28~33 weeks gestation than those in ones at 33~37 weeks gestation (P<0.01).Conclusion:In patients with a gestationl age of 28~34 weeks, a waiting management scheme was advised to decrease neonatal morbidity. Patients with PPROM should be prolonged more than 34 weeks' gestation at lease to decrease neonatal mortality.
