Utility of prophylactic antibiotics in pediatric adenoidectomy.
OBJECTIVE
To determine the utility of prophylactic antibiotics in non-risk pediatric patients undergoing adenoidectomy.


METHODS
We performed a prospective, controlled, randomized, and double-blind study on patients under 14 years of age, scheduled for adenoidectomy who accomplished the following criteria: absence of immunosuppressive and/or cardiovascular risk factors, no antimicrobial therapy for at least 15 days prior to operation, and no fever 1 week before surgery. Venous blood samples for culture were obtained at 30s and 20 min after the curettage of adenoidal tissue. Likewise, immediate and delayed complications were registered in all cases. The usefulness of prophylaxis was analyzed according to three major standpoints: bacteremia, immediate complications, and delayed complications.


RESULTS
One-hundred one patients fulfilled the inclusion criteria and were included in the study. Fifty-one children received prophylaxis and the remainder did not. In the non-prophylactic group incidence of bacteremia at 30s was significantly higher than in the prophylactic group (32.7% versus 4.0%) (p<0.001). Neither bacteremia at 20 min, nor immediate or delayed complications showed statistical differences between both treatment groups.


CONCLUSIONS
Preoperative antimicrobial prophylaxis in pediatric adenoidectomy did not offer advantages preventing complications in non-risk patients. Only bacteremia that occurs 30s after the curettage of adenoid tissue is reduced with the employment of prophylactic antibiotics.
