625例巨大儿分析

The Large Fetus:Analysis of 625 cases

我院11年间巨大儿占同期分娩总数的3.35%(661/19757人次),分析其中资料完整的625例,并与同期单胎、足月、体重2500～4000g(不包括4000g)的650例作比较。指出巨大儿组的过期妊娠发病率、男性巨大儿、母亲并发症、羊水过多、滞产、肩难产率及产后出血等均明显高于对照组(P<0.05)。建议采用"头盆指数"在产前明确诊断,并提高助产人员的技术水平,减低肩难产率,以降低围产儿患病率与病死率。

In a 11—year retrospective reviews of 19757 deliveries there were 661 infant weighing 4000g or more, constituting 3.35%, in which 825 patients' records were available. A comparison between these 625 patients and those of full term singleton weighing 2500g to 4000g was made during the same period. The results revealed high incidence of postdate pregnancy, male infant, prolonged labour, shoulder dystocia and postpartum hemorrhage,etc,in large fetus group is higher than that in the control group,and significant defference between these two groups was observed P<0.05. Shoulder dystocia, and perinatal mortality rates (PNMR) in the large fetus were 2.08%, 1.12% respectively, the difference between which and the normal fetus group was statistically significant P<0.05. It is suggested that early making diagnosis, well trained attendant and close surveilance for anticipation of the potential complication assoiatod with delivery of a large infant etc ,are very important for reducing the maternal and neonatal morbidity and maintain low PNMR.
