A good friend of mine's wife is at 38 weeks in her first pregnancy. Her platelet count has been decreasing steadily in the last few weeks. Her midwife said it's not critical but it is now at a level that is a concern, and it raises the chance of Cesarean section. Why would a Cesarean be a better choice in this situation? It seems if a patient has low platelets you'd want to minimize trauma to reduce the chance of bleeding. I know there can be significant trauma during birth, but abdominal surgery is pretty darn traumatic, too. Is it because the trauma of a vaginal birth is somewhat uncontrolled? Or is it to better control the separation of the placenta from the uterus?
