AbstractThe perioperative course of 41 patients undergoing 85 endoscopic laser resections of central airway lesions under general anaesthesia was reviewed. The CO2 laser was used in 60 procedures and the Nd:YAG in 25. Intravenous anaesthesia and Venturi ventilation were utilized for 65 resections; 20 procedures involved predominantly inhalation anaesthesia via the ventilating bronchoscope. Significant intraoperative complications included arterial desaturation (SaO2 less than 90 per cent) in 26 per cent of procedures, and refractory hypertension requiring vasodilator therapy in 19 per cent. Intravenous anaesthesia was associated with a longer duration of recovery room care and a higher incidence of postoperative respiratory complications (delayed extubation, recovery room re-intubation and ventilation, and post-extubation stridor). Inhalation anaesthesia appeared to simplify the intraoperative management and decrease the incidence, duration and severity of immediate postoperative respiratory complications.
