Background: There is a paucity of publications regarding doses of sedative medication during flexible bronchoscopy (FB) in substance-use patients. Objectives: The goal of this study was to compare the requirement of sedative medication in substance users with that in nonusers during bronchoscopy. Methods: A retrospective review of the sedation requirement was carried out in both groups. Results: One hundred patients were included, 50 in each group. The difference in the requirement for opioids and benzodiazepines was statistically significant. The mean doses for opioids and benzodiazepines in the substance-use group were 20 and 7 mg, respectively, compared with 8.7 and 3 mg for the nonsubstance group. Conclusions: Patients who use illicit drugs need higher doses of sedation during FB. A bronchoscopist should consider the clinical background of the patient to provide optimal sedation during FB, avoid undersedation, decrease patient discomfort during the procedure, and improve overall patient care.
