Abstract :

Overview: Awake fieoptic onchoscope (FOB) guided intubation is the gold standard of airway management in patients with difficult airway. It is essential to sufficiently anesthetize the upper airway before the performance of awake FOB guided intubation in order to ensure patient comfort and cooperation. This randomized controlled study was performed to compare two methods of airway anesthesia, Lignocaine viscous versus 10% Lignocaine Spray for preparation of airway in awake fieoptic intubation Materials and Methods: A total of 50 adult patients with difficult airway were randomly allocated into two groups. Group V received airway anesthesia with lignocaine viscus and Group S received 10% lignocaine spray and both commonly received airway blocks (bilateral superior laryngeal and transtracheal recurrent laryngeal) each with 2 ml of 2% lignocaine. FOB guided orotracheal intubation was then performed. Hemodynamic variables at baseline and during the procedure, patient recall, vocal cord visibility, ease of intubation, coughing/gagging episodes, and signs of lignocaine toxicity were noted. Results: The observations did not reveal any significant differences in hemodynamic parameters at any time during the study. However, the time taken for intubation was significantly more in group S as compared with the Group V. Maximum excellent score seen in the both groups but group V patients shows better satisfaction than others. Overall patient comfort was same in Group S and group V with fewer incidences of unpleasant recalls in group V. Conclusion: Both Lignocaine Viscous and 10% Lignocaine Spray for Preparation of Airway in Awake Fieoptic Intubation as assessed by patient haemodynamic parameters, coughing/gagging episodes, ease of intubation, vocal cord visibility, and time taken to intubate.
