目的观察改良Cho缝合术在前置胎盘孕妇剖宫产术中的临床应用效果。方法观察组62例前置胎盘孕妇在剖宫产术中采用改良Cho缝合术,对照组随机抽取2010年以前采用局部“8”字缝合开放血窦及宫腔纱条填塞压迫法的前置胎盘孕妇62例。结果 62例观察组中,平均手术时间85±22.35 min,术中出血量815.37±279.34 ml,34例输血,占54.84%,输血量800±400 ml,无一例切除子宫。而62例对照组中平均手术时间115±25.51 min,术中出血量1456±317.19ml,53例输血,占85.48%,输血量1200±600 ml,3例中央性前置胎盘产妇行子宫切除术。两组有统计学意义,P<0.01。结论对于前置胎盘的孕妇在剖宫产术中发生子宫下段胎盘附着处出血,采用改良Cho缝合术,大大减少了产妇的出血量,减少了输血的机率及输血量,缩短了手术时间,此方法安全简便,经济有效。
Objective To observe the clinical effect of modified Cho suture in cesarean section of pregnant women with placenta previa. Methods In the observation group, 62 cases of placenta previa in the cesarean section using modified Cho suture, the control group were randomly selected before 2010 using local “8 ” suture open sinusoids and uterine gauze packing compression method 62 cases of placenta pregnant women. Results In the observation group of 62 cases, the mean operative time was 85 ± 22.35 min, the intraoperative blood loss was 815.37 ± 279.34 ml, 34 cases were transfused, accounting for 54.84%, and the blood transfusion was 800 ± 400 ml. No case of uterine resection was found. In 62 cases, the average operation time was 115 ± 25.51 min, the intraoperative blood loss was 1456 ± 317.19 ml, 53 cases were transfused, accounting for 85.48% and the transfusion volume was 1200 ± 600 ml. Three cases of central placenta previa were treated by hysterectomy . The two groups were statistically significant, P <0.01. Conclusions For pregnant women with placenta previa, hemorrhage occurs in the placenta attached to the lower uterine segment during cesarean section, and the modified Cho suture can greatly reduce the amount of bleeding and reduce the chances of blood transfusion and blood transfusion and shorten the operation time. The method is safe, easy and cost-effective.
