目的探讨改良宫颈钳夹法在预防产后出血中的效果。方法将阴道顺产产妇共209例随机分为二组,钳夹组100例:于胎儿娩出后由助手随即用剖宫产子宫切口钳钳夹宫颈四个点30min;对照组109例不用钳夹。二组均在第三产程采用缩宫素20U静滴,观察二组产时出血与产后2h出血量,以及产后24h阴道出血量,并观察宫颈钳夹的不良反应。做统计学处理。结果二组产后2h持续出血量,钳夹组明显低于对照组,差异有统计学意义(P<0.01),二组产后出血发生率差异无统计学意义(P>0.05)。钳夹组无不良反应。结论改良宫颈钳夹法预防产后出血有临床意义。
Objective To investigate the effect of modified cervical clamp in preventing postpartum hemorrhage. Methods A total of 209 cases of vaginal delivery were randomly divided into two groups, 100 cases of clamping group: after the baby was delivered, the assistant then used the cesarean section uterine incision forceps to clamp the cervical four points for 30 minutes; the control group of 109 cases did not use the clamp. Both groups in the third stage of labor using oxytocin 20U intravenous infusion, observation of two sets of bleeding and 2h postpartum hemorrhage, and postpartum 24h vaginal bleeding, and observe the adverse reactions of cervical clamp. Do statistical analysis. Results The amount of continuous bleeding in 2 h postpartum was significantly lower in the clamp group than in the control group (P <0.01). There was no significant difference in the incidence of postpartum hemorrhage between the two groups (P> 0.05). No adverse reactions in the clamp group. Conclusion Modified cervical clamp method for the prevention of postpartum hemorrhage has clinical significance.
