Ertapenem compared to combination drug therapy for the treatment of postpartum endometritis after cesarean delivery.

OBJECTIVE

Ertapenem is a broad spectrum carbapenem approved for the treatment of postpartum endometritis. Data regarding clinical outcomes after treatment with ertapenem for endometritis after cesarean delivery are limited. Our objectives were to compare clinical outcomes and cost of ertapenem versus a multi-drug regimen for treatment of endometritis after cesarean delivery.

METHODS

Retrospectively, patients with endometritis after cesarean delivery who were treated with ertapenem (group A) were compared to those treated with a combination regimen (group B). Mann-Whitney U and Fisher's Exact were used for statistical analysis with p value <0.05 considered statistically significant.

RESULTS

Sixty-three patients were included: 31 in group A and 32 in group B. Demographics and intrapartum characteristics did not differ. Number of administered doses (A: 3, B: 11.5 p < 0.0001), cost (A: $156.63, B: $54.48 p < 0.0001) and nursing time in minutes (A: 6.6, B: 25.3 p < 0.0001) were different between both groups. Wound complications were higher in group A, occurring in 7 patients compared to 1 patient in group B (p = 0.024).

CONCLUSION

Although time and number of administered doses were less in group A, given the high wound complication rate in patients treated with ertapenem, this drug may not be appropriate for all patients with endometritis after CD.
