Introduction: The purpose of this study was to evaluate the efficacy of portable fibrescope in awake nasotracheal intubation for patients with anticipated difficult airway and to compare the use of combined nebulised lignocaine with Airway nerve blocks with nebulised lignocaine with spray– as– you– go technique in an attempt to compare ease of intubation and patient comfort in two accepted forms of airway anaesthesia for nasotracheal intubation in awake subjects with anticipated difficult airway undergoing surgery. Material And Methods: The study was carried out in tertiary care level hospitals affiliated to the Armed Forces Medical College. It was a longitudinal observational study to determine the time taken to intubation using two different techniques of airway anaesthesia viz Nerve blocks vis–à–vis Spray–as–you–go technique. Result: In our study overall patient comfort was better in Group NB with fewer incidences of unpleasant recalls as compared with Group SG. However, there was no statistically significant difference for quality of airway anaesthesia for intubation between groups. No difference for patient perception of discomfort during intubation.
