头位梗阻性难产的临床特点分析

The clinical characteristics of obstructive dystocia in celph-present

目的探讨头位梗阻性难产的现状、特点及其原因。方法采用回顾性分析方法对天津市中心妇产科医院1986年住院分娩的6667例中发生头位梗阻性难产925例和2004年住院分娩的4098例中发生或接受转诊的头位梗阻性难产148例,进行比较和分析。结果两个时期内造成梗阻性难产的最主要因素是持续性枕横位(ODP)和持续性枕后位(OPP),但2004年高龄产妇、非致死性畸形胎儿引产造成的梗阻性难产有增加趋势。结论密切观察产程进展和儿头下降是早期发现头位梗阻性难产的重要手段,提高妇产科医师的阴道助产水平是提高围生期质量的保证。
