Flexible fiberoptic bronchoscopy
Flexible fiberoptic bronchoscopy was performed in the operating room
with using Olympus CV-190 with CLV -190 EVIS EXERA III (Olympus, New
Hyde Park, NY, USA). In patients with suspected laryngomalacia,
primarily upper airway was evaluated. Deep sedation was achieved with
combination of ketamine and propofol following routine monitoring.
Spontaneous breathing was maintained under oxygen support and
respiratory support was provided with a face mask, if needed. After
evaluating upper airway, general anaesthesia with spontaneous
ventilation was achieved with laryngeal mask airway and total
intravenous anaesthesia with propofol without neuromuscular agent. While
the bronchoscope with an outer diameter of 3.8 mm was used in patients
whose body weights were ≤15 kg, the bronchoscope with an outer diameter
of 4.8 mm was used in heavier patients. During the procedure, 0.5-1 ml
%2 lidocaine with saline solution was given at the level of the vocal
cord and the main carina. Video images of all patients were recorded.
