OBJECTIVE: Flexible video bronchoscopy (FVB) performed under sedation is a useful procedure in adults with cystic fibrosis (CF). Propofol dosage for CF is poorly described, although it is of high importance for professionals. The study aimed to assess whether propofol dosage should be higher in adults CF undergoing sedation during FVB.
PATIENTS AND METHODS: 50 adult CF and non-CF patients undergoing sedation during FVB were included. Clinical features of studied patients were assessed. In CF group spirometry, liver enzymes, inflammatory biomarkers, albumin, protein concentration, WBC were estimated. Propofol and fentanyl dosage was calculated. Multiple regression model was performed.
RESULTS: CF patients were characterized by a lower mean value of body weight and lower mean requirement of total propofol (135 mg in CF vs. 145 mg in non-CF). Calculated propofol dose per kg of body weight was significantly higher in CF (2.43 mg/kg vs. 2.04 mg/kg) and did not depend on the bronchopulmonary disease stage. Propofol dose per kg of body weight was predicted by CF status (CF vs. non-CF), sex, and age.
CONCLUSIONS: Adult CF patients not receiving immunosuppressive therapy require higher propofol dose per kg of body weight compared to non-CF, independently on bronchopulmonary disease stage showing a narrow therapeutic window for propofol in CF group.Free PDF Download
