摘要
目的探讨剖宫产切口感染的高危因素,为其寻找最佳的预防措施和方法。方法采用回顾性调查方法,调查术后切口感染的产妇以及可能与感染相关的危险因素。结果在21个影响因素中,经产妇、肥胖、胎膜早破、住院时间和手术时间过长等14项为高危因素(P<0.01)。ASA评分,妊娠合并症等7项统计学无显著差异(P>0.05)。结论剖宫产切口感染的高危因素依次为:肥胖,入院前感染,胎膜早破,术前血色素偏低,手术时间过长,术前未使用预防性抗生素,入院后过多的阴检、肛查。进行判别分类显示,当过多的阴检、肛查存在时,感染预测率为75.2%,逐步加入下列因素,其感染预测率分别为:术前未使用预防性抗生素75.2%,术前血色素偏低82.4%,手术时间过长81.7%,肥胖86.3%,胎膜早破83.7%,入院前感染的存在为84.9%。
Objective To study the high-risk factors of surgical site infection after cesarean section. Methods We retrospectively reviewed cesarean section cases with surgical site infection and evaluated the high-risk factors related to the infection. Results and Conclusions Totally 14 factors were identified as the high-risk factors such as obesity, inadequate antibiotic prophylaxis, low ferrohemoglobin level, existing infection before hospitalization, multiple vaginal and anal examinations, premature rupture of membranes, and prolonged operative time. The 7 factors such as emergency operation were not shown to be significant high-risk factors. The probability of parturient with frequently vaginal examination to acquire infection following cesarean section was 75.2%, which was judged by classification analysis. A stepwise addition of the factors for analysis showed some difference in the predicted probability, which was 75.2% for inadequate antibiotic prophylaxis, 82.4% for low ferrohemoglo-bin level, 81.7% for prolonged operative time, 86.3% for obesity, 83.7% for premature rupture of the membranes, and 84.9% for existing infection before hospitalization.
