Cesarean delivery complications in women with morbid obesity.

OBJECTIVE

To compare cesarean complication rates between women with body mass index (BMI) 40-49.9 kg/m(2) and BMI ≥ 50 kg/m(2) and associations with surgical techniques.

METHODS

This retrospective cohort study from 2009 to 2014 included women who underwent cesarean with delivery BMI ≥ 50 and an equal number with BMI 40-49.9. Wound infections and/or separations were compared. We also examined wound complication rates between skin closure techniques and self-retaining retractor use.

RESULTS

Among 498 patients (249 with BMI ≥ 50 and 249 with BMI 40-49.9) there were no differences in estimated blood loss >1000 mL, blood transfusion, deep vein thrombosis or endometritis. Among those with outpatient follow-up (144 with BMI ≥ 50 and 162 with BMI 40-49.9), those with BMI ≥ 50 had a significantly higher rate of wound separations (p = 0.01) but not infections. There were no differences in wound complication rates between skin closure techniques or self-retaining retractor use, though the study was not powered for these comparisons.

CONCLUSION

Wound complications, particularly separations, increase with BMI ≥ 50 compared to a lesser degree of morbid obesity. Skin closure techniques and self-retaining retractor use were not associated with cesarean wound complications in patients with morbid obesity.
