How dangerous is c-section with placenta previa? i have heard there is a high risk of bleeding out!?

Good Hands Can Help: Placenta previa can pose difficulties during a cesarean because the placenta can be located in the area that the incision in uterus is made to deliver the baby. This may cause increased bleeding. A physician with skill should have little problem with getting it under control. More dangerous is placenta previa in someone who has had a cesarean with a prior pregnancy. But again, experience prevails.

Increased risk.: What you have heard is correct; exsanguination can occur in undiagnosed accreta/previa in small hospitals with inexperienced surgeon(s). Seek expert care if uou have placenta previa (including maternal-fetal medicine ultrasound and consultation), avoid all nsaids/sex/travel/unnecessary car rides/heavy lifting/straining/constipation and deliver in a large, tertiary care hospital [blood bank/icu].
