Abstract:ObjectiveTo investigate the clinical effect of U-shape suture combined with tourniquet on pernicious placenta previa (PPP) hemorrhage.Methods The clinical data of 245 patients with PPP hemorrhage treated from October 2013 to October 2018 were retrospectively analyzed.According to the hemostatic methods,120 patients in control group were treated with routine treatment combined with U-shape suture,and 125 patients in study group were treated with tourniquet on the basis of the regimen of control group.The therapeutic effects were compared between two groups.Results The effective rate of hemostasis in study group was significantly higher than that in control group (96.00% vs 85.00%, χ2=8.709, P<0.01）.The hysterectomy rate in study group was significantly lower than that in control group (1.60% vs 14.17%, χ2=13.516, P<0.01).The hemostasis time,the intraoperative blood loss,postoperative bleeding volume within 24 h and intraoperative blood transfusion volume in study group were significantly lower than those in control group ( P<0.01).No complications occurred during the operation in both groups.The incidence of postoperative complications in study group was statistically lower than that in control group (2.40% vs 10.00%, χ2=6.153, P<0.05).The duration of lochia discharge in study group was significantly shorter than that in control group ［(25.21 ± 3.65)d vs (29.35 ± 3.34)d, t=9.251,P<0.01］.Conclusion In the treatment of PPP hemorrhage,U-shape suture combined with tourniquet can improve the hemostatic effect,shorten the hemostasis time,reduce the bleeding volume,the risk of hysterectomy and complications and promote postoperative recovery.
