初产妇产前体重指数对正常产程的影响(2)

     本研究中對新生儿体重统计分析发现,产前正常体重组孕妇所生新生儿体重明显低于超重组和肥胖组,而超重和肥胖组之间无统计学差异。本研究中正常体重组无巨大儿,但是肥胖组和超重组均有巨大儿。因此分析正常组与肥胖组在产程时限方面的差异也与巨大儿有关。

    本研究回顾性分析了孕妇产前不同体重指数对于正常产程时限的影响,这些是本研究的创新之处。按照新产程标准,肥胖组从临产发动到宫口开大6cm较正常组时间延长0.84小时,提示临床中对于肥胖孕妇第一产程宫口开大6cm之前可以适当延长时间,不能简单将潜伏期延长作为剖宫产指征。对于肥胖孕妇应给与充分的试产时间,尤其是孕妇处在潜伏期内,在无头盆不称及可疑胎儿窘迫情况下,缓慢但有进展的第一产程,可继续试产。同时,本研究还提示要重视孕期体重控制,为此要加强孕期宣教,正确指导营养,合理控制孕期体重增长,避免产前肥胖,不仅可降低妊娠期糖尿病、妊娠期高血压、巨大儿的发生率,同时也有利于产程顺利进展,降低宫口扩张或宫口扩张停滞的发生率,同时避免盆底软组织增厚带来的分娩负面影响。
