〔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.
