Given this pattern, the higher rates of transfusion
and ICU admission for primary cesareans compared with repeat
cesareans was somewhat unexpected. However, a multicenter U.S.study that focused specifically on transfusions for women undergoing
cesarean delivery also found an increased incidence in primary
compared with repeat cesarean deliveries (19). The findings for ICU
admission are new, with no other large U.S. studies available that
examine this specifically by method of delivery and previous
cesarean history.
