Background: The study was conducted to study the benefits of using alkalinized lidocaine 40 mg for filling the cuff of an endotracheal tube (ETT) to prevent post-intubation sore throat. Methods: The current study was conducted to study the diffusion of alkalinized lidocaine solution through the low-pressure, high-volume cuff of an ETT. A comparative study was conducted with 50 patients in each group, with lignocaine group which received an alkalinized lidocaine to fill ETT cuff and control groups who received air to fill ETT cuff. Results: Our study revealed that the incidence of sore throat was much lower in lignocaine group as compared to air group. The study also revealed that there was a considerable decrease in the hemodynamic response in lignocaine group as compared to air Group and there were no complications like endotracheal tube cuff rupture and alkalinized lignocaine toxicity. Conclusions: Alkalinized intracuff lignocaine helps in reducing post extubation sore throat and also has decreased hemodynamic response to extubation when compared to intracuff air which offers no advantage. In addition alkalinized lignocaine intracuff maintains a stable cuff pressure during oxygen nitrous anaesthesia thus, preventing the damages that occur due to increased cuff pressure during general anaesthesia.
Keywords: lidocaine intracuff extubation.
