目的:评价自然分娩中会阴正中切开术的临床效果。方法:随机取711例头位自然分娩的初产妇,抽取会阴正中切开组100例,会阴侧切组100例,观察产后会阴切口肿胀、疼痛、感染及愈合情况。结果:在娩出新生儿体重无统计学差异时,会阴正中切口的产妇以上几个方面情况均优于侧切组(P<0.001)。结论:会阴正中切开术切口符合生理要求,临床应用效果优于传统会阴侧切术。
Objective: To evaluate the clinical effect of median perineal incision in spontaneous labor. Methods: Seven hundred and seventy cases of primipara caused by spontaneous delivery were randomly selected. One hundred cases of midline incision and 100 cases of perineal episiotomy were selected for observation of swelling, pain, infection and healing of perineal incision. Results: When there was no significant difference in the birth weight of the newborn, the median circumferences of the perineal incision were better than those of the lateral incision group (P <0.001). Conclusion: The perineal incision incision accords with the physiological requirements, the clinical application is better than the traditional episiotomy.
