孕妇体重指数与产后切口感染的关系

Relationship between body mass index of pregnant women and postpartum incision infection

目的:探讨孕妇体重指数(BM I)与产后切口感染的关系。方法:选取单胎初产妇360例作为研究对象,分别按照孕前和产前BM I分组:①孕前BM I≥25者33例为孕前肥胖组,孕前BM I<25者327例为孕前正常组;②产前BM I≥28者204例为产前肥胖组,产前BM I<28且孕期体重增长不超过15 kg者156例为产前正常组。分别随访产妇腹部或会阴切口愈合情况。结果:孕前肥胖组及产前肥胖组与正常组切口愈合情况比较,甲级、乙级及丙级愈合率均有统计学差异(P<0.05)。结论:孕前BM I≥25、产前BM≥I28是产后切口感染的危险因素,控制孕前BM I及孕期体重过度增长,可降低产后切口感染率。

Objective：To explore the relationship between body mass index（BMI） of pregnant women and postpartum incision infection.Methods：360 primiparous women of single pregnancy were selected and divided into pre-pregnant BMI group and antenatal BMI group： 33 pregnant women with pre-pregnant BMI≥25 were pre-pregnant obesity group,327 pregnant women with pre-pregnant BMI25 were pre-pregnant normal weight group;204 pregnant women with antenatal BMI≥28 were antenatal obesity group,156 pregnant women with antenatal BMI28 and weight gain during pregnancy no more than 15 kg were antenatal normal weight group,the healing conditions of abdominal and perineal incision were followed up.Results：There was significant difference in healing rates of grade A,B and C between pre-pregnant obesity group,antenatal obesity group and pre-pregnant normal weight group,antenatal normal weight group（P〈0.05）.Conclusion：Pre-pregnant BMI≥25 and antenatal BMI≥28 are risk factors of postpartum incision infection,the rate of postpartum incision infection may be reduced by controlling pre-pregnant BMI and weight gain during pregnancy.
