Anesthesia in Flexible Bronchoscopy for Lung Cancer Diagnostic

This prospective randomized study analyzed 80 patients that underwent flexible bronchoscopy. Patients were randomly assigned to four groups of 20 patients each according to the anesthetic combination used: 200 mg topical lidocaine (LID group); 200 mg topical lidocaine and 2 mg/kg propofol (PPF group); 200 mg topical lidocaine and 20 mcg/kg alfentanil (ALF group); or 200 mg topical lidocaine and 0.05 mg/kg midazolam (MID group). Scores were assigned to patients according to the different variables observed during the endoscopic procedure; the lower the score, the lower the complication index.
