Nebulized Gentamicin as an Alternative to Nebulized Tobramycin for Tracheitis in Pediatric Patients.

Abstract

Tracheitis is an infection of the lower respiratory tract and is defined by the US Centers for Disease Control and Prevention (CDC) based on signs and symptoms with no radiographic evidence of pneumonia. One method of treatment involves the use of tobramycin given by nebulizer. The purpose of this study was to compare the safety and efficacy of nebulized gentamicin with nebulized tobramycin. This study was conducted in patients under 21 years of age who received greater than or equal to 1 day of gentamicin, 80 mg, or tobramycin, 300 mg, given twice a day by nebulization within the 14-month study period. The primary endpoint was amount of time until the patient no longer met the CDC definition of tracheitis. There were 19 patients who presented with 60 separate encounters. The average age of the patients within the gentamicin group was 7.2 and 5 years old within the tobramycin group. The average duration of time for the gentamicin treatment encounters to be free of the CDC definition of tracheitis was 3.36 days compared to 3.17 days with tobramycin. No adverse effects were observed that were attributable to aminoglycoside nebulization. No differences were detected between the safety and efficacy of intravenous gentamicin administered twice a day by nebulizer and that of tobramycin inhalation solution given twice daily in children without cystic fibrosis.
