〔摘 要〕 目的：分析双股自制止血带用于三次剖宫产产妇预防产后出血（PPH）的效果。 方法：选取 2020 年 1 月至 2022 年 12 月上饶市妇幼保健院收治的 80 例三次剖宫产产妇为研究对象，采用随机数字表法分为观察组与对照组，各 40 例。 两组均在子宫下段剖宫产取出胎儿后采用缩宫素＋麦角新碱注射液宫体注射治疗，观察组在此基础上加用双股自制止血带 止血。比较两组产妇术中、术后 24 h 出血量、产后宫底下降速度与恶露持续时间。 结果：观察组产妇术中、术后 24 h 出血 量均少于对照组，差异具有统计学意义（P ＜ 0.05）；观察组产妇产后宫底下降速度快于对照组，产后恶露持续时间短于 对照组，差异具有统计学意义（P ＜ 0.05）。 结论：双股自制止血带应用于三次剖宫产产妇可有效减少术中、术后出血量， 促进产妇产后康复。
〔Abstract〕 Objective To analyze the effect of double strand homemade tourniquet on prevention of postpartum hemorrhage (PPH) in women with three caesarean sections. Methods A total of 80 women with three cesarean sections admitted to the Shangrao Maternal and Child Health Hospital from January 2020 to December 2022 were selected as the research objects. Random number method was used to divide the group into an observation group and a control group, 40 cases in each group. Both groups were treated with uterine injection of oxytocin + ergotrine injection after the fetus was removed in the lower part of the uterus during caesarean section, and the observation group was treated with double strand homemade tourniquet for hemostasis on the basis of this. The amount of blood loss during and 24 hours after operation, the rate of descension of postpartum floor and the duration of lochia were compared between the two groups. Results The intraoperative and postoperative blood loss 24 hours in the observation group were lower than those in the control group, the differences were statistically significant (P < 0.05). The descending rate of postpartum floor in the observation group was faster than that in the control group, and the duration of postpartum lochia was shorter than that in the control group, the differences were statistically significant (P < 0.05). Conclusion The application of double strand homemade tourniquet in three caesarean sections can effectively reduce the amount of intraoperative and postoperative bleeding and promote postpartum recovery.
