29例剖宫产手术切口感染的回顾性分析及预防策略

目的：探讨剖宫产手术切口感染的危险因素，为有效预防和控制剖宫产手术切口感染提供科学依据。方法采用回顾性调查方法，2011年12月至2012年12月在该院实施剖宫产手术发生切口感染的29例产妇作为观察组，抽取同期未发生切口感染的29例产妇作为对照组，比较两组各方面的差异，确定切口感染的危险因素。结果589例剖宫产中有29例发生切口感染，感染率为4．9％。单因素分析结果显示，观察组产妇 BMI（25．9±1．1）kg／m2，疤痕子宫6例，急诊手术18例，手术时间（1．2±0．6）h ，住院时间（7．1±2．3）d ，合并基础疾病为6例，胎膜早破为12例，阴道及肛诊次数（3．3±0．6）次，与对照组各项比较，差异有统计学意义（P＜0．05）。多因素分析结果显示，BMI（OR ＝2．802）、手术时间（OR ＝5．813）、合并基础疾病（OR ＝6．182）、胎膜早破（OR ＝11．219）为剖宫产手术切口感染的独立危险因素。结论多种因素影响手术切口感染，对高危人群采取针对性的预防控制措施，从而降低剖宫产手术切口感染率。

Retrospective analysis and preventive strategies in the cesarean section operation incision infection of 29 cases

Objective To investigate the risk factors of cesarean section operation incision infection ,so as to provide refer‐ence for preventing and controlling cesarean section operation incision infection effectively .Methods A total of 29 cases were se‐lected who hospitalized in our hospital during December 2011 and December 2012 and whose incision of cesarean operation was in‐fected as the observation group .They were retrospectively analyzed .Then another 29 cases were chosen whose incision of cesarean operation was not infected as the control group .The clinical data in two groups were compared and the risk of infected incision were investigated .Results The incision infection occurred in 29 of 589 cases undergoing cesarean section with the infection rate 4 .9% . Univariate analysis showed that ,the maternal BMI in observation group was (25 .9 ± 1 .1)kg /m2 ,uterine scar for 6 cases ,emergency operation for 18 cases ,operation time was(1 .2 ± 0 .6) h ,the hospitalization time was (7 .1 ± 2 .3) d ,6 cases with underlying disease , premature rupture of membranes for 12 cases ,the vagina and anus diagnosis number was(3 .3 ± 0 .6) times ,the comparison with the control group ,the difference was statistically significant (P< 0 .05) .Multivariate Logistic regression analysis showed ,BMI (OR =2 .802) ,operation time (OR = 5 .813) ,with basic diseases (OR = 6 .182) ,premature rupture of membranes (OR = 11 .219) were risk factors for cesarean section operation incision infection .Conclusion There are many factors that can influence the surgical incision infections .It is necessary for the high‐risk population to take effective measures to prevent surgical incision infections .
