To explore the safety and effectiveness of early suture of uterine incision on the basis of avoiding intrauterine operation in cesarean section of placenta previa.

A total of 158 pregnant women with placenta previa who underwent cesarean section at the First Affliated Hospital of Guangxi Medical University from 2014 to 2019 were selected as the research subjects. The patients were divided into either a study group (n=74) or a control group (n=79) according to the random number table method; the study group was treated by modified cesarean section and the control group was treated with conventional cesarean section. The operation parameters (operation time, reduction of peripheral blood hemoglobin 24 hours after operation, incidence of postpartum hemorrhage, blood transfusion ratio, amount of red blood cell suspension transfused, and postoperative hospital stay) and postoperative complications (poor healing of abdominal incision and intrauterine infection) were observed and compared between the two groups.

The mean age of patients in the study group was (35.0±5.4) years, and it was (34.0±4.3) years in the control group; there was no significant differences between the two groups (P＞0.05). The operation time, the incidence of postpartum hemorrhage, and postoperative hospital stay in the study group were all significantly lower than those in the control group [(48.85±13.80) min vs (67.27±20.87) min, 6.3% vs 17.7%, and (4.30±0.79) d vs (4.71±1.28) d, respectively; P＜0.05]. There was no significant difference in the level of peripheral blood erythrocytes or hemoglobin between the two groups before operation (both P＞0.05). The levels of peripheral blood erythrocytes and hemoglobin at 24 hours after operation were lower than those before operation, but the reduction in the study group was less than that in the control group [(12.07±7.85) g/L vs (15.54±8.86) g/L, P＜0.05]. The transfusion ratio, the amount of red blood cell suspension transfused, and the incidence of postoperative complications in the study group were all slightly lower than those in the control group, but there was no significant differences between the two groups (P＞0.05).

In cesarean section of placenta previa, on the basis of avoiding intrauterine operation, suturing uterine incision as early as possible can effectively reduce intraoperative bleeding, which is safe, reliable, simple, and easy to learn.
