BACKGROUND The role of midazolam in flexible bronchoscopy premedication has been debated. The aim of the present study was to evaluate whether midazolam premedication increases the patient-reported tolerance and the physician-reported or nurse-reported feasibility of bronchoscopy. METHODS: Randomized, double-blinded, placebo-controlled, 3-arm study. The study population included patients undergoing bronchoscopy for appropriate clinical indications. Patients were randomly assigned to receive 0.035 mg/kg intravenous midazolam (low dose), 0.07 mg/kg (high dose), or placebo. Vital parameters were monitored in continuum during the procedure. At the end of the procedure, the operating physician and assisting nurse filled out a questionnaire to score the procedure-related outcomes (satisfaction, feasibility, completeness, and unexpected events). Patients were asked to fill out a specific questionnaire to assess the patient-reported tolerance and satisfaction 2 hours after the bronchoscopy. RESULTS: A total of 100 patients (mean age 58.6±1.0; 57% male) were included in the study (33 in the low-dose midazolam group, 34 in the high-dose midazolam group, and 33 in the placebo group). The patient-reported tolerance score was significantly higher in the high-dose midazolam group than in the placebo group (P<0.01). No differences were found in the 3 groups in terms of the physician-reported feasibility and completeness of the procedure. In the groups of patients premedicated with midazolam, significant oxygen desaturation was recorded (at 10 and 8 min after the introduction of the bronchoscope) compared with the baseline value (P<0.01). CONCLUSIONS: In our study, premedication with midazolam increased the patient-reported tolerance of the bronchoscopy. However, the absence of premedication did not affect the diagnostic yield of the procedure.

Abstract

BACKGROUND The role of midazolam in flexible bronchoscopy premedication has been debated. The aim of the present study was to evaluate whether midazolam premedication increases the patient-reported tolerance and the physician-reported or nurse-reported feasibility of bronchoscopy. METHODS: Randomized, double-blinded, placebo-controlled, 3-arm study. The study population included patients undergoing bronchoscopy for appropriate clinical indications. Patients were randomly assigned to receive 0.035 mg/kg intravenous midazolam (low dose), 0.07 mg/kg (high dose), or placebo. Vital parameters were monitored in continuum during the procedure. At the end of the procedure, the operating physician and assisting nurse filled out a questionnaire to score the procedure-related outcomes (satisfaction, feasibility, completeness, and unexpected events). Patients were asked to fill out a specific questionnaire to assess the patient-reported tolerance and satisfaction 2 hours after the bronchoscopy. RESULTS: A total of 100 patients (mean age 58.6±1.0; 57% male) were included in the study (33 in the low-dose midazolam group, 34 in the high-dose midazolam group, and 33 in the placebo group). The patient-reported tolerance score was significantly higher in the high-dose midazolam group than in the placebo group (P<0.01). No differences were found in the 3 groups in terms of the physician-reported feasibility and completeness of the procedure. In the groups of patients premedicated with midazolam, significant oxygen desaturation was recorded (at 10 and 8 min after the introduction of the bronchoscope) compared with the baseline value (P<0.01). CONCLUSIONS: In our study, premedication with midazolam increased the patient-reported tolerance of the bronchoscopy. However, the absence of premedication did not affect the diagnostic yield of the procedure.
