目的探讨“30°改良会阴侧切术”在限制性会阴切开中的临床作用。方法在行阴道分娩限制性会阴切开过程中,将需要追加会阴侧切的100例单胎、头位、足月低危初产妇作为研究对象,根据随机数字表法分为观察组和对照组,每组50例。观察组给予30°改良会阴侧切,对照组给予传统的45°会阴后侧切。两组产妇均配以“慢出胎头、慢娩肩”原则。比较两组产妇会阴伤口撕裂情况、产时伤口出血量、产后伤口疼痛程度及持续时间、伤口愈合程度。结果 30°改良会阴侧切术损伤小,出血量少、疼痛轻、愈合好。结论在实行限制性会阴切开过程中,对需要追加侧切的妇女,30°改良会阴侧切和传统45°会阴后侧切有同样防止会阴严重撕裂伤的作用,同时减轻了产妇的损伤,提高了产科质量。
Objective To investigate the clinical effect of “30 ° modified episiotomy” in the limitation of episiotomy. Methods During the period of vaginal delivery restricted perineal incision, 100 cases of single birth, head, full-term low-risk primipara required for episiotomy were divided into observation group and control group according to random number table method. 50 cases in each group. The observation group was given 30 ° modified episiotomy, while the control group was given the traditional 45 ° perineal incision. Two groups of mothers are accompanied by “slowly out of the fetal head, slow delivery shoulder ” principle. The perineal wound tear, maternal wound bleeding, postpartum wound pain and duration, wound healing were compared between the two groups. Results 30 ° improved perineal excision less injury, less bleeding, light pain, good healing. Conclusions During the practice of restrictive perineal incision, women with additional lateral incision, 30 ° modified perineal and traditional 45 ° perineal circumcision have the same effect of preventing severe laceration of the perineum while reducing maternal injury and improving Obstetric quality.
