Objective: To evaluate the method of avoiding incision of the placenta using partial separation of the anterior placenta previa during cesarean delivery and to compare the outcomes between this method and the conventional method involving transection of the placenta.

Patients and Methods: In this retrospective study, subjects were categorised into two groups: 32 patients underwent placental transection to rupture the membranes (transection group), and 22 patients underwent deliver partial separation of the placenta for membrane rupture (non-transection group). Maternal and fetal outcomes, including the operative time, volume of blood loss, maternal transfusion of packed red blood cells, Apgar score, new-born hemoglobin, and blood gas analysis, were compared.

Results: The surgical blood loss was significantly lower in the non-transection group (P<0.05). There were no significant differences in operation time and incision to delivery time (P>0.05) between the two groups. Neonatal blood gas analysis show that the pH and Base Excess (BE) values were significantly decreased (P<0.05) while the blood lactic acid was significantly increased (P<0.05) in the transection group compared to the non-transection group. The Apgar scores at 1 min and new-born hemoglobin levels did not significantly differ between in the groups (P>0.05).

Conclusions: Avoiding incision of the anterior placenta previa may help reduce the risk of intrapartum hemorrhage and neonatal acidosis.
