目的 探讨剖宫产术中出血的有关因素。方法 对该院过去 7a间剖宫产术病例进行回顾性分析。将剖宫产术中出血 15 6例作为研究组 ,同期 62 4例剖宫产病例作为对照组。结果 研究组中有前置胎盘 44例 ,占 2 8 2 % ;对照组前置胎盘 12例 ,占 1 9% ,两组比较差异有显著性 (P <0 0 5 % )。研究组胎儿体重≥ 40 0 0g(双胎为两者体重之和 )共 3 2例 ,占 2 0 5 % ( 3 2 / 15 6) ;对照组为 78例 ,占 12 5 % ( 78/ 62 4) ,两组比较P <0 0 5。孕次“一次”两组比较无差异 ,而“一次以上”研究组比例大于对照组 ,差异有显著性 (P <0 0 5 )。研究组急诊剖宫产 70例 ,占 44 9% ( 70 / 15 6) ,与对照组比较 ,差异有极显著性 (P <0 0 0 5 )。结论 剖宫产出血主要与前置胎盘、宫缩乏力、孕次、剖宫产时机、子宫切口撕裂有关。严格掌握剖宫产指征 ,正确把握剖宫产时机 ,做好充分术前准备 ,是减少剖宫产出血的关键。
Objective To investigate the related factors of bleeding during cesarean section. Methods A retrospective analysis of 7 cases of cesarean section in the hospital over the past years. Fifty-six cases of hemorrhage in cesarean section were included in the study group, and 62 4 cases of cesarean section in the same period were served as the control group. Results There were 44 cases of placenta previa in the study group, accounting for 28.2%. In the control group, 12 cases were placenta previa, accounting for 19%. There was significant difference between the two groups (P <0.05%). The study group had a total body weight of 40 0 0g (twins as the sum of their body weights), 32 cases (20%), while 78 cases (125%) in the control group (78/62 4), P <0 05 for both groups. Pregnancy “once” no difference between the two groups, while “more than once” study group than the control group, the difference was significant (P <0 05). There were 70 cesarean sections in the study group, accounting for 44.9% (70/156). There was a significant difference between the two groups (P <0 05). Conclusion Cesarean section bleeding is mainly associated with placenta previa, uterine atony, pregnancy time, cesarean delivery timing and uterine incision tear. Strict control of indications for cesarean section, correctly grasp the timing of cesarean section, adequate preoperative preparation, is to reduce the key to bleeding cesarean section.
