Abstract
Objective To observe the clinical effects of placental edge incision on the treatment of central placenta previa .Methods Sixty-four cases of central placenta previa treated in the First Huizhou Maternal and Child Health Hospital were chosen from April 2011 to January 2013.They were randomly divided into two groups on computer: experiment group and control group both with 32 cases.In the experiment group , the cesarean section was conducted in the way of placental edge incision , while in the control group it was in the way of incision of lower uterine segment .Key indexes were compared between two groups , including amount of bleeding during the operation , operation time , recovery of uterus , uterine resection , neonatal asphyxia rate , postoperative complications and adverse reactions .Results In the experiment group , the amount of bleeding during the operation was obviously less than that in the control group (376.45 ±129.65mL vs 734.56 ±156.34mL, t=9.9741,P<0.05),but the operation time was obviously longer (56.31 ±8.92min vs 45.62 ±7.91min, t=5.0862,P<0.05).The neonatal asphyxia rate was obviously less in the experiment group than in the control group (3.13%vs 25.00%,χ2 =4.6545, P<0.05).There was no statistical significance in the recovery of uterus and the uterine resection (P>0.05).After the operation, there were no complications or adverse reactions in both groups .Conclusion In the application of new placental edge incision in central placenta previa operation ,the amount of bleeding during operation is less and neonatal asphyxia rate is lower than the traditional lower uterine segment method .So it is worth widely using in clinicas .关键词
