Abstract:
Background and aims: In order to reduce endotracheal tube (ETT) induced emergence phenomenon at extubation which involves postoperative sore throat (POST), cough, hoarseness, dysphagia and hemodynamic changes , we evaluated the efficacy of vegetable gum based (VGB) Lubic gel lubrication alone or in combination with 4% intracuff alkalinized lignocaine (IAL). The vegetable gums in the gel appear to be of special significance. Methodology: 100 patients undergoing surgical procedures under general anesthesia were randomly allocated to 4 groups of 25 each. In Group C (control group) patients, the ETT cuffs were inflated with air and lubricated with normal saline. In Group G, the cuffs were inflated with air, while in Group L and LG, cuffs were filled with IAL. The Group G and LG cuffs were lubricated with VGB lubricant gel while Group L cuffs were lubricated with normal saline. During the post-extubation period POST was studied using Visual Analogue Scale (VAS) at 15 min, 1, 2, 3 and 24 h. Incidence of cough, dysphagia, hoarseness and hemodynamic changes was recorded and compared. Results: The mean VAS scores for POST were found to be the least in Group LG (12.6 ± 7.08) compared to Groups C (33.8 ± 9.38), G (32.52 ± 2.11) and Group L (21.6 ± 12.30) over 24 h. Incidence of cough, dysphagia, hoarseness and hemodynamic changes was least in Group LG compared to others. Conclusion: VGB gel lubrication combined with IAL enhanced the effect of IAL, than IAL or VGB gel lubrication alone thus proving most effective in preventing emergence phenomenon at extubation.
