ABSTRACT
BACKGROUND: Patient-controlled sedation (PCS) with propofol is a safe and effective method of attenuating discomfort during fiberoptic bronchoscopy. The purpose was to evaluate the usefulness of midazolam in addition to PCS for fiberoptic bronchoscopy. METHODS: We randomly assigned 155 patients undergoing diagnostic bronchoscopy to two groups. Group M (n = 79) received 0.03 mg/kg of midazolam for premedication while group P (n = 76) received a loading dose (0.05 ml/kg) of PCS solution composed of 200 mg (20 ml) of propofol and 1 mg (2 ml) of alfentanil. Both groups received the PCS solution 0.2 ml/kg/hr with a bolus of 1 ml and a lockout time of 1 min. Vital signs, pulmonologist satisfaction, patient satisfaction and amnesia were evaluated. RESULTS: After the insertion of the bronchoscope, there was a slight decrease of SpO2 and an increase of blood pressure and heart rate in both groups with no significant differences between the two groups. The group P required more bolus injections (1.6 +/- 1.7 in the group M vs 2.5 +/- 2.2 in group P; P < 0.05). There was no difference in the satisfaction of pulmonologists, but the satisfaction of patients was higher in the group M (P < 0.05). More patients in the group P (93%) remembered the procedure than in the group M (70%) (P < 0.05). CONCLUSIONS: PCS is an effective method for sedating patients undergoing fiberoptic bronchoscopy and midazolam provides more patient satisfaction and amnesia.
