Randomized Comparison of Sharp Versus Blunt Techniques at Cesarean

Unintended Extension of the Lower Segment Uterine Incision at Cesarean Delivery;A Randomized Comparison of Sharp Versus Blunt Techniques

The purpose of this study is to determine whether a specific surgical technique, blunt compared with sharp expansion of the transverse lower uterine incision, is associated with risk of unintended extension of uterine incision
