初产妇产褥期感染的相关危险因素调查分析

Investigation analysis on correlated risk factors of puerperal infection of primipara

目的探讨初产妇产褥期感染的相关危险因素，为早预防产褥期感染提供依据。方法将确诊的80例产褥期感染产妇作为病例组，同时选择80例未发生产褥期感染的初产妇作为对照组，使用调查表回顾性收集相关因素，采用单因素和多因素方法来筛选可能影响初产妇产褥期感染的危险因素。结果初产妇产褥期感染率为1．75％（80／4653）；多因素logistic回归分析结果显示妊娠期贫血（OR=3．708）、合并生殖道炎症（OR=7．618）、胎膜早破（OR=4．301）、剖宫产（OR=2．059）、产程延长（OR=3．226）、产后出血（OR=5．659），均为初产妇产褥期感染的危险因素。结论初产妇产褥期感染发生率仍然较高，影响其产褥期感染的独立危险因素包括妊娠期贫血、合并生殖道炎症、胎膜早破、剖宫产、产生延长及产后出血。应针对这些危险因素采取干预措施。

Objective To explore the correlated risk factors of puerperal infection of primipara, and to provide basis for early prevention of puerperal infection of primipara. Methods Eighty definite cases of puerperal infection of primipara were chose as case group, and 80 cases of normal primipara without puerperal infection as control group. With questionnaire we retro- spectively collected correlated factors which were screened by single factor and multiple factors methods. Results The incidence rate of puerperal infection of primipara was 1.75% （80/4653）. Multiple factors logistic Regression analysis result showed that a- naemia of gestational period （ OR = 3. 708 ）, complication of gential tract inflammation （ OR= 7. 618）, premature rupture of mem- branes （ OR=4. 301 ）, uterine-incision delivery （ OR = 2. 059 ）, prolonged labor （ OR = 3. 226 ） and postpartum hemorrhage （OR = 5. 659） were the risk factors of puerperal infection of primipara. Conclusion There is a comparatively high incidence rate of puerperal infection of primipara. And the independent risk factors include anaemia of gestational period, complication of gential tract inflammation, premature rupture of membranes, uterine-incision delivery, prolonged labor and postpartum hemor- rhage. We should adopt intervention measures to aim directly at these risk factors.
