目的:探讨剖宫产术子宫下段切口撕裂的原因及预防措施。方法:对我院行子宫下段横切口剖宫产术发生切口撕裂的46例临床资料进行回顾性分析。结果:本组子宫切口撕裂占同期剖宫产术的6.2%。枕后位、胎先露≥+3、宫口扩张≥7cm、麻醉效果差、巨大儿、子宫下段形成差者子宫切口撕裂率高,反之子宫切口撕裂率低。结论:子宫下段横切口撕裂是剖宫产术常见的并发症,术前正确判断胎方位、胎先露下降及宫口扩张程度、胎儿大小、子宫下段形成情况,并采取改变麻醉方法、切口方向、手术方式等相应措施,可有效避免子宫切口撕裂。
Objective: To investigate the causes and preventive measures of incision of lower uterine incision in cesarean section. Methods: A retrospective analysis was performed on 46 cases of incision laceration in cesarean section underwent transverse incision in the lower uterine segment of our hospital. Results: This group of uterine incision cesarean section accounted for 6.2% of the same period. Occipital posterior position, fetal first exposed ≥ +3, cervix expansion ≥ 7cm, poor anesthesia, macrosomia, lower uterine segment formation of high rate of hysterectomy incision, uterine incision tear instead. Conclusion: The transverse incision in the lower uterine segment is a common complication of cesarean section. The position of fetus and fetus are decreased and the expansion of cervix, the size of fetus and the formation of lower uterine segment are correctly determined before operation. The anesthesia method and incision Direction, surgical methods and other appropriate measures can effectively prevent the uterine incision tear.
