OVERVIEW: Awake fiberoptic bronchoscope (FOB) guided intubation is the gold standard of airway management in @entity1 with @entity130 . It is essential to sufficiently anesthetize the upper airway before the performance of awake FOB guided intubation in order to ensure @entity1 comfort and cooperation. This randomized controlled study was performed to compare two methods of airway anesthesia, namely ultrasonic nebulization of local anesthetic and performance of airway blocks. MATERIALS AND METHODS: A total of 50 adult @entity1 with @entity130 were randomly allocated into two groups. Group L received airway anesthesia through ultrasonic nebulization of 10 ml of 4% @entity3303 and Group NB received airway blocks (bilateral superior laryngeal and transtracheal recurrent laryngeal) each with 2 ml of 2% @entity3303 and viscous @entity3303 gargles. FOB guided orotracheal intubation was then performed. Hemodynamic variables at baseline and during the procedure, @entity1 recall, vocal cord visibility, ease of intubation, coughing/gagging episodes, and signs of @entity3303 @entity137 were noted. RESULTS: The observations did not reveal any significant differences in demographics or hemodynamic parameters at any time during the study. However, the time taken for intubation was significantly lower in Group NB as compared with the Group L. Group L had an increased number of coughing/gagging episodes as compared with Group NB. @entity3746 and ease of intubation were better in @entity1 who received airway blocks and hence the amount of supplemental @entity3303 used was less in this group. Overall @entity1 comfort was better in Group NB with fewer incidences of unpleasant recalls as compared with Group L. CONCLUSION: Upper airway blocks provide better quality of anesthesia than @entity3303 nebulization as assessed by @entity1 recall of procedure, coughing/gagging episodes, ease of intubation, vocal cord visibility, and time taken to intubate.
