wound infections were less frequent in cases with previous cesarean sections ( relative risk = 0.15 ) and after elective cesarean sections ( relative risk = 0.22 ) , but duration of operation over 1 h ( relative risk = 2.8 ) , induction of labor ( relative risk = 3.2 ) and puerperal endometritis ( relative risk = 7.9 ) increased the risk of wound infection .
