目的探讨剖宫产术中结扎双侧子宫动脉上行支在中央性前置胎盘中的临床效果。方法回顾性分析2007年12月—2012年12月在永康市妇幼保健院住院手术的中央性前置胎盘患者108例,其中37例在胎盘娩出后行双侧子宫动脉上行支结扎的患者为病例组;另外42例未行子宫动脉上行支结扎的患者为对照组。观察两组手术时间、出血量、输血率及子宫切除率。结果病例组手术时间(60.89±11.91)min,明显少于对照组(70.64±13.15)min(P﹤0.01);病例组术中出血量(851.35±307.42)mL,明显少于对照组(1 191.67±562.87)mL(P﹤0.01);病例组术后24 h出血量(1 032.43±333.59)mL,明显少于对照组(1 402.38±490.64)mL(P﹤0.01);病例组输血率24.32%,明显低于对照组52.38%(P﹤0.05);病例组子宫切除率0%,与对照组2.38%比较,差异无统计学意义(P﹥0.05)。结论在中央性前置胎盘剖宫产术中结扎子宫动脉上行支后可以缩短手术时间,减少术中术后失血量,降低输血率。
Objective To investigate the clinical effect of ligation of bilateral uterine artery in central placenta previa in cesarean section. Methods A retrospective analysis of 108 patients with central placenta previa who underwent surgery in Yongkang MCH from December 2007 to December 2012 was retrospectively analyzed. Among them, 37 patients underwent bilateral uterine artery ligation after the placenta was delivered Group; another 42 patients without uterine artery ligation of the ligation of the control group. The operation time, blood loss, blood transfusion rate and hysterectomy rate were observed. Results The operation time in the case group was significantly lower than that in the control group (60.89 ± 11.91) min (70.64 ± 13.15) min (P <0.01). The intraoperative blood loss was 851.35 ± 307.42 mL in the case group, which was significantly lower than that in the control group ± 562.87) mL (P <0.01). The amount of bleeding in the case group at 24 hours after surgery was (1032.43 ± 333.59) mL, which was significantly lower than that in the control group (1240.3 ± 490.64) mL , Which was significantly lower than that of the control group (52.38%, P <0.05). The hysterectomy rate was 0% in the case group and 2.38% in the control group, with no significant difference (P> 0.05). Conclusions Ligation of uterine artery in the central placenta previa leads to shorter operative time, less postoperative blood loss and lower blood transfusion rate.
