Two methods of sedation were evaluated in unpremedicated patients undergoing elective bronchofiberoscopy. The patients were randomly allocated to receive either propofol infusion 1 mg kg-1 h-1 preceded by a 1 mg kg-1 bolus (15 patients) (the propofol group) or intravenous fentanyl 1 micrograms kg-1 and diazepam 0.05 mg kg-1 (15 patients) (the fentanyl+diazepam group). Thirteen patients were treated twice during the study period and sedated with both methods (the first treatment according to random order and the second with the method not used on the first occasion). A topical anaesthetic was applied to the selected nostril with two cotton swabs soaked in 4% lidocaine. Epiglottis, vocal cords, trachea and bronchi were anaesthetized by spraying 4% lidocaine through the working channel of the fiberoscope as the instrument was advanced. The patients in the propofol group were more sedated than those in the fentanyl+diazepam groups (P less than 0.01). The working conditions were the same. After sedation, respiratory frequency decreased only in the fentanyl+diazepam group (P less than 0.05). Before sedation, haemoglobin saturation of oxygen was 95 +/- 2% (mean +/- s.d.) in the propofol group and 94 +/- 3% in the fentanyl+diazepam group. Immediately before the start of bronchofiberoscopy, it was 89 +/- 4% and 90 +/- 3%, respectively. The decrease was statistically significant in both groups (P less than 0.001). After sedation, systolic arterial pressures (SAP) decreased in both groups (P less than 0.01). Compared to values immediately before starting bronchofiberoscopy, SAP increased during the procedure in both groups (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
