Comparison of Sufentanil, Fentanyl and Remifentanil in Combination With Midazolam During Bronchoscopy Under Conscious Sedation: A Randomized Double-blind Prospective Study

The best opioid for bronchoscopy is still unclear.This randomized double-blind prospective study was conducted on a total of 60 patients who were randomly allocated into 3 groups: Group S received sufentanil 0.1 mcg/kg, Group F received fentanyl 1 mcg/kg and Group R received remifentanil target-controlled infusion with effect-site target concentration of 1ng/ml. Patients in all groups received midazolam to achieve moderate levels of sedation as assessed by the Narcotrend (NT; between B1 and C2). Adverse events, patient tolerance and physician satisfaction were analized.
