近年来剖腹产率有逐渐上升的趋势,剖腹产虽可减少因阴道手术所致的婴儿损伤或死亡,但术后感染及严重出血的发生也相应增多,其危害性甚大,应引起重视。资料我院从1980年1月至1983年5月共发生剖腹产术后子宫切口感染性大出血7例,其中有1例系院外手术后转来我院。同期剖腹产总数为1,799例,发病率占剖腹产总数0.39％。经积极处理,无一例死亡。我院常规采用子宫下段横行切口,先切开肌层约2cm,然后用手指钝性撕开子宫肌层。缝合切口时均以1号肠线连续缝合肌层2次。术后常规用抗生素预防感染。本文7例均作了次全子宫切除术,术中所见大多数为原切口感染,尤以两侧角为重,组织脆且薄,轻压之即通入宫腔,病理诊断多为产后子宫内膜炎及子宫肌炎。(病历摘要见下表) Caesarean section rate in recent years, there is a gradual upward trend, although caesarean section can reduce the risk of vaginal surgery due to infant injury or death, but the incidence of postoperative infection and severe bleeding also increased accordingly, its great harm should be taken seriously. Materials In our hospital from January 1980 to May 1983 a total of 7 cases of caesarean section incisional hemorrhage after caesarean section occurred, of which 1 case was transferred to our hospital after surgery outside the hospital. Caesarean section over the same period a total of 1,799 cases, the incidence of total caesarean section 0.39%. After active treatment, no one died. In our hospital routine use of transverse incision in the lower uterine segment, first cut the muscle layer about 2cm, and then blunt tear myometrium with your fingers. Stitching and incision were No. 1 gut continuous suture muscle 2 times. Postoperative antibiotics to prevent infection. In this paper, 7 cases were made subtotal hysterectomy, most of the original surgical findings of infection, especially in both sides of the angle as the weight, tissue crisp and thin, light pressure that is, access to the uterine cavity, pathological diagnosis mostly postpartum Endometritis and uterine myositis.
