Does uterine wiping influence the rate of post-Cesarean endometritis?
OBJECTIVE
To compare two methods of uterine cleansing to remove residual amnion-chorion at the time of Cesarean delivery.


METHODS
All consenting uninfected parturients undergoing a non-emergency Cesarean delivery at the university were enrolled. All patients received antibiotic prophylaxis of a 1-g intravenous bolus of a first-generation cephalosporin immediately after cord clamping. Postpartum endometritis was defined as a temperature of > or = 100.4 degrees F (38 degrees C) on two occasions 6 h apart after the first 24 h with uterine tenderness and/or foul-smelling lochia.


RESULTS
Between January 1998 and February 2000 there were 1400 patients enrolled in this investigation. A total of 153 women were determined to have chorioamnionitis present at surgery and 17 women refused participation, leaving 614 women in the uterine wipe group and 616 in the no wipe group. Maternal demographics were similar between patient groups (NS). Intrapartum factors including gestational age at time of Cesarean section, type of anesthesia used for the operative delivery, hours of amnion rupture prior to delivery, use of internal monitoring devices, type of skin incision, method of placental removal, total operative time and estimated blood loss were similar between patient groups (NS). An almost identical number of patients in each arm of the study developed post-Cesarean endometritis (65 out of 614, 10.5%, in the uterine wipe group vs. 66 out of 616, 10.7%, in the no wipe group; p = 1).


CONCLUSIONS
Both methods of removing residual amnion-chorion membrane tissue and associated debris at surgery were comparably effective, but neither produced a dramatic reduction in the incidence of postoperative endometritis.
