目的:观察钙剂辅助缩宫素预防剖宫产产后出血的临床效果。方法:将240例行剖宫产分娩的无血液系统疾病、有剖宫产指征、存在产后出血高危因素的足月妊娠孕产妇随机分为观察组和对照组。观察组:120例,于术前30min应用5%葡萄糖注射液250mL或氯化钠注射液250mL加10%葡萄糖酸钙10mL静脉点滴,胎儿娩出后立即宫体注射缩宫素20U;对照组:120例,胎儿娩出后宫体注射缩宫素20U。检测产后2h内出血量,以容积法及称重法计算出血量,大于400mL为产后出血。结果:产后2h内出血量,观察组为(282±156)mL,对照组为(346±180)mL。观察组术后2h出血量均低于对照组,2组比较有统计学意义(P<0.05)。观察组产后24h血红蛋白平均下降值明显低于对照组(P<0.05)。结论:钙剂辅助缩宫素可减少剖宫产产后出血量,方法简单有效。
Objective: To observe the clinical effect of calcium-assisted oxytocin in preventing bleeding after cesarean section. Methods: 240 cases of cesarean delivery without blood diseases, cesarean indications, there are high risk factors for postpartum bleeding pregnant women were randomly divided into observation group and control group. Observation group: 120 cases, 250ml of 5% glucose injection or 250ml of sodium chloride injection and 10ml of calcium gluconate 10mL were intravenously dripped 30min before the operation. The oxytocin 20U was injected into the uterine body immediately after the delivery. The control group: 120 For example, the fetus was delivered after injection of oxytocin 20U. Detect the amount of bleeding within 2h postpartum, volume method and weighing method to calculate the amount of blood, more than 400mL for postpartum hemorrhage. Results: The amount of bleeding within 2 hours after delivery was (282 ± 156) mL in the observation group and (346 ± 180) mL in the control group. The amount of bleeding in observation group 2h after operation was lower than that in control group, the two groups were statistically significant (P <0.05). The mean hemoglobin decrease in observation group was significantly lower than that in control group (P <0.05). Conclusion: Calcium-assisted oxytocin can reduce postpartum hemorrhage after cesarean section, the method is simple and effective.
