Abstrakt: Background and Aims: Awake fibreoptic intubation is considered a safe approach in airway management of a patient with difficult airway. Awake fibreoptic endoscopy needs appropriate anaesthesia of airway to suppress airway reflexes and prevent discomfort. We planned this study to evaluate effect of adding dexmedetomidine to lignocaine nebulization on conditions for awake videoendoscopic intubation. Material and Methods: In this prospective randomized double blind controlled study, ninety six ASA grade I, II patients of either gender, aged 18-65 years, scheduled for elective surgeries under general anaesthesia, were randomly allocated into two groups, Group D and L to receive nebulization with 4% Lignocaine 5 ml + Dexmedetomidine 2 mcg/kg and 4% Lignocaine alone respectively, 20 min before procedure. Time taken to intubate the patient, ease of intubation assessed by cough severity score, patient comfort score, post-intubation patient satisfaction and hemodynamic changes were recorded and compared. Results: Group D and L had comparable intubation time (196.8 ± 61.2 s) and (205.8 ± 52.2 s) (p = 0.437). Cough severity, patient comfort and quality of procedure with post intubation patient satisfaction score were significantly better in Group D. Haemodynamics parameters were better post nebulization in group D as compared to group L. Conclusion: Addition of Dexmedetomidine 2 mcg/kg with 4% Lignocaine during nebulization improves intubating conditions during awake flexible videoendoscopy in terms of ease of intubation, cough severity, patients comfort and satisfaction along with providing stable Haemodynamics profile.
