Objective To explore the haemostatic efficacy of cervical progressing suture in treating intractable cervical canal hemorrhage during cesarean section(CS) in placenta previa.Methods Sixty patients suffering from intractable cervical canal hemorrhage during CS due to central placenta previa were chosen and divided into the cervical progressing suture(observation roup,30 cases) and the uterine cavity ribbon gauze packing group(control group,30 cases).The intraoperative operating time,intraoperative bleeding amount,postoperative 24 h hemorrhage amount,hysterectomy and puerperal infection were compared between the two groups.Results The intraoperative operation time in the observation group and control group were (3.15± 1.60)min and (6.10±2.35) min respectively,the intraoperative bleeding amount in the observation group and control group were (422.00 ±-186.98)mL and (642.25±344.42)mL respectively,postoperative 24 h bleeding amounts were (583.23±=198.33)mL and (825.23±=373.50)mL respectively,the differences between the two groups were statistically significant(P＜0.05).No hysterectomy and no complications ocurred in each group.Conclusion Adopting the cervical progressing suture in treating intractable cervical canal hemorrhage during cesarean section(CS) due to placenta previa is simple to operate and has good effect.
