为探讨影响术中异常出血的因素,对我院3年来,39例临床资料作回顾性分析。结果:剖宫产术中异常出血发生率4.5％。胎儿体重过大,子宫肌纤维过度伸展,收缩不良,先露下降受阻,头位异常,导致宫缩乏力;产程延长,头位异常及先露高低均可出现宫缩乏力,尤其是枕后位,先露过低使子宫损伤机会增多;胎盘位置异常及粘连,剥离面渗血明显升高。因此,防治术中异常出血,要严格掌握手术适应证,术中根据产程长短、胎头位置高低、子宫情况,选择适宜子宫切口及娩出胎儿的方式。
To explore the factors that affect the intraoperative abnormal bleeding, our hospital for 3 years, 39 cases of clinical data for retrospective analysis. Results: The incidence of abnormal bleeding in cesarean section was 4.5%. Fetal weight is too large, uterine muscle fibers over-stretched, poor contraction, first revealed the decline blocked, head anomalies, leading to uterine atony; prolonged labor, head anomalies and the level of exposure may appear uterine atony, especially after the occiput, The first exposed low so that the uterus increased the chance of injury; placental abnormalities and adhesions, exfoliated surface oozing was significantly higher. Therefore, the prevention and treatment of intraoperative abnormal bleeding, surgery should be strictly controlled indications, surgery based on length of labor, fetal head position, the uterus, choose the appropriate uterine incision and delivery of the fetus.
