Brief Summary
The hypothesis of this study is that extending the second stage of labor beyond current American College of Obstetricians and Gynecologists suggestions can reduce the cesarean delivery rate. The cesarean delivery rate in the United States is around 30 percent. This is a number that continues to be increasing over the last few decades and will continue to climb. Each subsequent cesarean section puts the mother and baby at increased risk for postpartum hemorrhage, bowel and bladder injury, abnormal placentation, febrile morbidity and death. The most common reason for a cesarean delivery is a repeat cesarean delivery. One way to reduce this number is to prevent the first cesarean delivery. The aim of this study is evaluate if extending the second stage of labor affects the cesarean delivery rate and subsequent perinatal morbidity.
