Los ANGELES -- A high maternal body mass index predicted an increased risk for infection following elective and nonelective cesarean section in a retrospective study of 574 deliveries.
Most previous studies on the risk of infection after C-section have considered only nonelective procedures, Dr. Thomas D. Myles said at the annual meeting of the American College of Obstetricians and Gynecologists.
The results led Dr. Myles of Texas Tech University, Amarillo, to recommend using prophylactic antibiotics for all nonelective C-sections but especially in obese patients.
Overall, 15% of patients developed infections, including 9% of 214 women undergoing elective C-section and 18% of 360 women with nonelective C-sections.
In the elective cesarean group, a high body mass index (BMI) was the only factor that predicted an increased risk for infection after multivariate analysis controlled for possible confounding variables, In obese patients undergoing an elective C-section, prophylactic antibiotics appeared to lower the chance of developing an infection.
In the nonelective cesarean group, four factors predicted a greater risk of infection after multivariate analysis: a higher BMI, obesity (defined as a BMI greater than 30 at the ...
