高龄产妇剖宫产术后切口感染的相关因素分析

Related factors for incision infections in advanced maternals after cesarean section

目的探讨高龄产妇剖宫产后出现切口感染的相关因素以及干预措施,减少术后切口感染的发生。方法回顾性分析2007年5月-2012年5月医院收治的剖宫产高龄产妇600例临床资料,总结高龄产妇剖宫产后切口感染的危险因素,数据采用SPSS 13.0软件进行分析。结果高龄产妇在剖宫产后发生切口感染79例,感染率13.17%;发生切口感染的产妇入院时BMI指数明显偏高、备皮至手术时间以及手术时间明显较长、术中出血量也明显较多(P<0.05);经过logistic回归分析,上述因素是高龄产妇剖宫产术后发生切口感染的独立危险因素;而有无剖宫产史、剖宫产的原因、术后是否放置引流条、手术时机以及手术切口的长度与在剖宫产后是否发生切口感染无关(P>0.05)。结论高龄产妇剖宫产术后发生切口感染受到多种因素的影响,在临床工作中应针对这些影响因素给予积极的干预措施,以减少切口感染的发生率。

OBJECTIVE To explore the related factors for incision infections in advanced maternals after cesarean section and put forward intervention measures so as to reduce the incidence of postoperative incision infections. METHODS A total of 600 advanced maternals who underwent the cesarean section in the hospital from May 2007 to May 2012 were enrolled in the study, then the clinical data of the subjects were retrospectively analyzed, the risk factors for the incision infections were summarized, and the data were statistically analyzed with the use of SPSS 13.0 software. RESULTS Among the advanced maternals undergoing the cesarean section, the postoperative incision infections occurred in 79 cases with the infection rate of 13.17%. The logistic regression analysis indicated that the high BMI at the admission to the hospital, long interval between skin preparation and surgery, long oper- ation duration, and large volume of intraoperative blood loss were the independent risk factors for the postopera- tive incision infections in the advanced maternals undergoing the cesarean section （P〈0.05）, while the history of cesarean section, reason for cesarean section, postoperative placement of drainage strip, timing for operation, and length of surgical incision were negatively correlated with the incision infections after the cesarean section （P〉 0. 05）. CONCLUSION There are a variety of influencing factors for the postoperative incision infections in the advanced maternals undergoing the cesarean section. It is necessary to take targeted intervention measures in response to the influencing factors so as to reduce the incidence of incision infections.
