ObjectiveTo evaluate the efficacy and safety of inhaled tobramycin (TOBI) in the treatment of ventilator-associated pneumonia (VAP) in a randomized, double-blind pilot study.Patients And MethodsTen patients from a cohort of 108 mechanically ventilated patients with documented clinical and bacteriological evidence of VAP caused by Pseudomonas aeruginosa or Acinetobacter spp. in the surgical and trauma intensive care units of a university teaching hospital were randomized to receive either TOBI (n = 5) or intravenous tobramycin (TOBRA; n = 5). The two groups were similar in their Acute Physiology and Chronic Health Evaluation (APACHE) score, Clinical Pulmonary Infection Score (CPIS), and Multiple Organ Dysfunction Score (MODS) prior to randomization. The primary outcome measure was resolution of pneumonia. The CPIS and MODS were used as objective indicators of clinical progress.ResultsAll TOBI patients had clinical resolution of VAP. Two TOBRA patients were considered failures. One had deterioration in MODS, and the other had doubling of his serum creatinine concentration. The patients treated with TOBI may have had more ventilator-free days than those receiving TOBRA, but the difference was not statistically significant owing to the small sample size (24 +/- 3 vs. 14 +/- 13 days; p = 0.12).ConclusionAerosolized tobramycin for the treatment of VAP appeared safe and effective in this pilot study. A larger study is warranted to determine if aerosolized tobramycin will lead to better outcomes than intravenous tobramycin when used for the treatment of VAP.
