Steroid therapy following isolated smoke inhalation injury.

Steroids have no positive influence upon pulmonary related morbidity and mortality following combined smoke inhalation and thermal cutaneous injury (3, 4). Steroid administration following isolated smoke inhalation without concomitant thermal cutaneous injury has, however, been shown to have beneficial effects in previous animal studies (1). This potential therapeutic approach to treatment has not been examined in the clinical setting. Recent hotel fires in Las Vegas, Nevada, resulted in a large cohort of individuals with similar smoke exposures without associated injuries. Two of four hospitals in the triage system administered steroids following injury. Patients were divided into two groups, a steroid-treated, and a non-treated group. These groups were compared using multivariate and frequency analyses. There were no detectable differences in sex, signs, symptoms, and previous medical history. There were likewise no differences between groups with respect to oxyhemoglobin saturation, arterial oxygen tension, arterial pH, and pulmonary-related morbidity and mortality. These data suggest that steroid coverage has little beneficial effect upon pulmonary-related morbidity and mortality following isolated smoke inhalation injury.
