【摘要】 目的 :调查应用无保护会阴分娩技术的产妇会阴裂伤情况,并分析其危险因素,为对症护理及早期预防提供依据。方法 :回顾性分析2015年11月至2016年4月我院分娩室应用无保护会阴分娩技术助产的563例产妇会阴裂伤的发生率及严重程度,并采用Logistic回归分析研究其危险因素。结果 :无保护会阴分娩产妇会阴裂伤的发生率为63.6%,其中Ⅰ度裂伤占93.9%,Ⅱ度裂伤占6.1%;Logistic回归分析结果显示,初产妇、胎儿体质量3 500~3 999 g、助产士工作年限<5年、产前会阴水肿是无保护会阴分娩产妇发生会阴裂伤的独立危险因素。结论 :应用无保护会阴分娩技术的产妇同样存在会阴裂伤的情况,但损伤程度较轻,多以Ⅰ度裂伤为主;应针对危险因素进行全面的产前评估并采取相应预防措施,减少无保护会阴分娩产妇会阴裂伤的发生。更多还原

【Abstract】 Objective: To explore the current status and risk factors of maternal perineal laceration among lying-in women using unprotected perineal delivery technique, and to provide guidance for early prevention and nursing care of the perineal laceration. Methods: Retrospective analysis of the incidence, severity and risk factors of perineal laceration among 563 lying-in women using unprotected perineal delivery technique from November 2015 to April 2016 in our hospital. Results: The incidence of perineal laceration among lying-in women using unprotected perineal delivery technique was 63.9%. The major injury type of perineal laceration is I degree laceration(93.9%) and II degree laceration(6.1%). Logistic regression analysis showed that the independent risk factors of perineal laceration were primipara, fetal weight 3500-3999 g, midvives working years less than 5 years and prenatal perineum edema(P<0.05). Conclusion: Lying-in women using unprotected perineal delivery technique could develop perineal laceration, but the major injury type is I degree laceration. We should conduct comprehensive assessment according to the risk factors before delivery and take corresponding preventive measures to reduce the incidence of perineal laceration.更多还原
