OBJECTIVE: To compare the effectiveness of intravenous penicillin vs clindamycin for the treatment of aspiration pneumonia. DESIGN: A double-blind, randomized controlled trial. SETTING: A tertiary care pediatric hospital. PATIENTS: We enrolled 42 children, aged 6 months to 18 years, who were admitted to the hospital for the treatment of aspiration pneumonia. All of the children had underlying conditions that predispose to aspiration. INTERVENTION: The patients were randomly assigned to receive intravenous penicillin G sodium, 250,000 U/kg every 24 hours, or intravenous clindamycin phosphate, 30 mg/kg every 24 hours. MAIN OUTCOME MEASURE: The primary outcome measure was "time to ready for discharge" from the hospital. RESULTS: In an effectiveness (intention to treat) analysis, the median time (interquartile range) to ready for discharge from the hospital was 4.9 days (range, 2.8-6.5 days) in the penicillin-treated group and 3.4 days (range, 2.3-6.8 days) in the clindamycin-treated group (P = .66). Results were not markedly altered when adjusted for the age difference of the groups or in the efficacy analysis (after the exclusion of 9 patients who withdrew from the trial). Rates for readmission to the hospital were similar in the 2 groups. CONCLUSION: Penicillin and clindamycin seem to be equally effective for the treatment of aspiration pneumonia in children hospitalized for this illness.
