Abstract:
Objective To investigate postpartum blood lose of cesarean section (CS) within 24 hrs in Nanjing area Methods Stratified samples were collected from hospitals of different levels and located at different districts The amount of postpartum blood loss was precisely measured by methods of weight, volume and area Results There were 1 125 CS in a total of 4 171 deliveries The main indications for CS were cephalo pelvic disproportion, fetal distress, breech presentation, and there was 10 4% of CS without definite causes The average amount of blood loss was 520 ml in CS, which was far more than that in vaginal delivery ( n = 3 046) If postpartum hemorrhage (PPH) is defined as blood lose of 500ml or more, the incidence of PPH was 53 7%; if it is defined as 700 ml, the incidence was 19 8% Conclusions Cesarean section is an important cause of PPH, and CS without proper indication should be avoided It seems reasonable to defined the criteria of PPH in CS as 700 ml or more
