剖宫产术对母婴基本是安全的。但术后可并发晚期严重大出血,导致子宫切除或危及生命。晚期大出血主要是子宫切口严重感染,组织坏死,切口裂开,血管开放出血,尤其是宫旁侧角口裂开造成大出血。为此我们重点在术式及包埋缝合切口角进行改进,取得满意效果。 Cesarean section is basically safe for mother and baby. However, postoperative complications may be severe late bleeding, resulting in hysterectomy or life-threatening. Late hemorrhage is mainly a serious infection of the uterine incision, tissue necrosis, incision rupture, blood vessels open bleeding, especially in the lateral fossa of the cervix caused by bleeding. To this end we focus on surgery and embedded incision incision angle to improve and achieve satisfactory results.
