目的避免或减少剖宫产切口撕裂。方法回顾性分析115例剖宫产子宫切口撕裂产妇,从子宫切口撕裂与先露下降程度、胎方位、宫口扩张程度、子宫切口位置、扩大子宫切口方式、胎儿大小及胎位、剖宫产前产程的关系进行分析。结果胎头深固时子宫切口撕裂率明显高于高浮及衔接(P<0.01);胎方位以枕后拉撕裂率最高,宫口扩张8~10cm子宫切口撕裂率高。切口距膀胱腹膜反折>3cm切口撕裂率显著增高。子宫切口撕裂与胎儿体重有关,术前产程越长,子宫切口越容易撕裂。结论子宫切口撕裂与胎先露高低、胎方位、宫口扩张程度、子宫切口位置、扩大子宫切口方式、胎儿大小、剖宫产前产程有关。
Objective To avoid or reduce cesarean section incision tear. Methods A retrospective analysis of 115 cases of cesarean section with uterine incision torn maternal tear from the uterine incision and the first show the degree of decline, fetal position, cervix expansion, uterine incision position, to expand the uterine incision, fetal size and fetal position, cesarean section Prenatal labor relations to analyze. Results The tear rate of uterine incision was significantly higher than that of high floating and convergence (P <0.01). The fetal tear rate was the highest in the occipital posterior direction and the rate of uterine incision in the cervix was 8 ~ 10 cm. Incision from the bladder peritoneal fissure> 3cm incision tear rate was significantly higher. Uterine incision tear and fetal weight related to the longer the preoperative labor process, the easier the uterine incision tear. Conclusion The incidence of uterine incision is related to the fetal height, fetal position, the degree of uterine dilatation, the position of uterine incision, the way of enlarging uterine incision, the size of fetus, and the cesarean section.
