会阴侧切术用来防止会阴Ⅲ度裂伤,使胎儿娩出顺利,缩短第二产程。本世纪侧切术率增加,如1979年阴道分娩中的施术率在丹麦为38%,美国为62%,英国为55%。但术后有相当多的会阴病痛, 故使某些学者对此术在产科中的作用有所争议。虽进行了一些有关的研究,尚未能确定会阴病痛是由缝合材料抑或缝合方法所致。作者为减少这类病痛,将1981年5月至1982年12月间分娩的产妇随机分为三组,以观察不同缝合材料,不同缝合方法的效果。第一组用00号普通肠线连缝阴道、间断缝合肌层筋膜,00号尼龙线间断缝合皮肤。术后5天拆线。第二组缝合方法同上,但各层均用0号多甘醇酸缝
Circumferential episiotomy used to prevent perineal third degree laceration, so that the fetus delivered a smooth, shorten the second stage of labor. This century, the rate of excision increased. For example, the rate of vaginal delivery in 1979 was 38% in Denmark, 62% in the United States and 55% in the United Kingdom. However, there are considerable postoperative perineal pain, so that some scholars on the role of obstetrics in the controversial. Although some relevant studies have not been able to determine whether the perineal sore material is caused by suture material or suture method. To reduce this type of illness, the authors randomized women giving birth between May 1981 and December 1982 to three groups to observe the effects of different sutures and different sutures. The first group with 00 common catgut joint vaginal, intermittent suture myometrial fascia, 00 nylon line intermittent sutured skin. 5 days after the stitches. The second group suture method above, but each layer with No. 0 polyglycolic acid suture
