会阴切开阴道助产861例临床分析

Analysis of 816 Cases of Perineotomy Parturition

目的：对会阴切开阴道助产术适应症及母婴预后的分析，指导临床正确掌握会阴切开阴道助产术，提高接生技术，倡导自然分娩。方法：对我科 1998年 1月至 2000年 7月间会阴切开阴道助产的 861例产妇进行回顾性分析。结果：合理的会阴切开阴道助产是非常必要的，会阴切开阴道助产率在 37％左右为好，初产妇应控制在 49％左右较为合适，在此侧切率下新生儿窒息率为 6.6％，产妇并发症、后遗症约 5.58％。结论：会阴切开阴道助产术在第二产程中为避免会阴及盆底严重裂伤，减轻盆底组织对胎头的压迫、缩短第二产程、加速分娩、降低新生儿窒息率具有很大的意义，只有合理掌握手术的指征以及避免过多干预和进行手术助产，会阴切开阴道助产术就可取得良好的效果，侧切率就能得到很好的控制，否则将会产生一系列并发症，对母婴带来很大的危害。
