ABSTRACT
Objective:To explore the effect of perineal lateral incision and continuous suture of deep and superficial Ⅱdegree laceration on postoperative perineum rehabilitation of parturients.Methods:Randomized controlled trials of intervention effects on postoperative maternal wound rehabilitation using continuous sutures and interrupted sutures of mucosal, muscle, and skin layers after perineal lateral resection and Ⅱdegree lacerations were searched in Cochrane Library, PubMed, Medline, Embase, Science direct, China Biology Medicine, China National Knowledge Infrastructune, Wanfang Database, VIP Database. The retrieval time limit was from database establishment to October 1, 2020. using RevMan 5.3 software for statistical processing.Results:After searching and screening, 12 articles were finally included. The total sample size was 2 827 cases. After the two groups used different suture techniques, the results of Meta analysis showed that the pains ( MD=1.02, 95% CI=1.02-1.06), the suture time ( MD=-4.59, 95% CI=-7.29 - -1.91) and the healing condition ( MD=-0.55, 95% CI=-0.71 - -0.39) of the two groups were compared, the differences were significant (all P<0.01). Conclusions:In the suture of perineal lateral incision and Ⅱdegree laceration, continuous suture technique is used to suture the mucosal layer, muscle layer, and cortex, which can reduce the suture time, reduce the pain of the parturient, and is beneficial to the healing of the wound. It can be clinically based on the parturient. It can be used in accordance with the neatness and depth of the mouth and the needs of the parturient.
