无保护性自然分娩与常规分娩对产后感染的影响及其影响因素分析

The effects of unprotected natural delivery and routine delivery on postpartum infection and its influencing factors

目的分析无保护性自然分娩与常规分娩对产后感染的影响及其影响因素。方法选取2019年10月至2020年10月于本院建档并分娩的1000名产妇作为研究对象,依据随机数字表法分为研究组和对照组,每组500名。对照组采用常规分娩,研究组采用无保护性自然分娩,比较两组感染情况,根据是否发生产后感染分为感染组(n=56)和未感染组(n=944),分析产后感染的影响因素。结果1000名产妇中,产后感染56名,占比5.6%,产后未感染944名,占比94.4%;其中研究组感染率为3.8%(19/500),明显低于对照组的7.4%(37/500),差异有统计学意义(P<0.05)。感染组与未感染组有无并发症、是否严格消毒、侵入性操作、是否人工宫腔操作比较差异有统计学意义(P<0.05)。多因素Logistic回归分析显示,有并发症、未严格消毒、侵入性操作≥2次、有人工宫腔操作是产后感染的危险因素(OR>1,P<0.05)。结论无保护性自然分娩的产后感染率低于常规分娩产妇,有并发症、未严格消毒、侵入性操作≥2次、有人工宫腔操作是产后感染的危险因素,临床需积极采取针对性措施,以预防产后感染的发生。

Objective To analyze the effect of unprotected natural delivery and routine delivery on postpartum infection and its influencing factors.Methods A total of 1000 puerperae who were archived and delivery in our hospital from October 2019 to October 2020 were selected as the research subjects,and they were divided into the study group and the control group according to the random number table method,with 500 in each group.The control group was given routine delivery,while the study group was given unprotected natural delivery.The infection situation were compared between the two groups,and they were divided into infected group(n=56)and uninfected group(n=944)according to the occurrence of postpartum infection,and the influencing factors of postpartum infection were analyzed.Results Among the 1000 puerperae,56 cases were infected,accounting for 5.6%;and 944 cases were not infected,accounting for 94.4%;among them,the maternal infection rate in the study group was 3.8%(19/500),which was significantly lower than that of 7.4%(37/500)in the control group,and the difference was statistically significant(P<0.05).There were significant differences between the infection group and the uninfection group in whether there were complications,strict disinfection,invasive operation,and artificial uterine cavity operation(P<0.05).Multivariate Logistic regression analysis showed that complications,not strictly sterilized,invasive operations≥2 times,and artificial uterine cavity operations were risk factors for postpartum infection(OR>1,P<0.05).Conclusion The rate of postpartum infection in unprotected natural delivery is lower than that in routine delivery,complications,not strictly sterilized,invasive operations≥2 times,and artificial uterine cavity operations are risk factors for postpartum infection,and it is necessary to actively take targeted measures to prevent the occurrence of postpartum infection.
