剖宫产术后不同部位感染的术前、术中及术后相关危险因素的分析

目的:分析剖宫产术后不同部位感染的术前、术中及术后的影响因素。方法:回顾性分析行剖宫产手术975例的临床资料。其中以剖宫产术后发生感染的产妇58例为观察组,随机选择未出现感染的产妇72例为病例对照组。分析不同部位感染的相关危险因素。结果:单因素分析提示肥胖、有多次流产史、术前多次导尿、肛门及阴道检查、术前未预防性使用抗生素、术前血红蛋白低、胎膜早破、手术时间长、术中出血多的例数或比例在观察组中明显多于对照组(P<0.05)。结论:肥胖、有多次流产史、术前多次尿道、肛门及阴道检查、术前预防性使用抗生素、术前血红蛋白、胎膜早破、手术时间、术中出血等因素为患者术后感染的相关危险因素。

Clinical analysis of the preoperative,intraoperative and postoperative related risk factors for a surgical site infection after a cesarean section

Objective To analyze the preoperative,intraoperative and postoperative factors for a surgical site infection after a cesarean section.Methods A retrospective survey of 975 women who underwent a cesarean section was conducted.The rate of surgical site infection was estimated and a nested case control study was then carried out to identify the risk factors.58 cases of maternal infection after a cesarean section were defined as observation group,at the same time 72 maternity patients were randomly selected from the rest women without infection,these cases were defined as control group,then we analyze the related risk factors for a surgical site infection.Results Single factor analysis indicated that the rate and proportion of women with obesity,history of miscarriages,excessive preoperative catheterization,anal and vaginal examination,a lack of preoperative prophylactic antibiotics,low preoperative hemoglobin,premature rupture of membranes,long operation time,more intraoperative bleeding in the observation group were lower than that in the control group（P〈0.05）.Conclusion Obesity,history of miscarriages,excessive preoperative catheterization,anal and vaginal examination,lack of prophylactic antibiotics,premature rupture of membranes,lower preoperative hemoglobin,prolonged surgery,volume of intraoperative bleeding during hospitalization are considered to be related risk factors for a surgical site infection after a cesarean section.
