DOI: https://doi.org/Background: Postoperative sore throat (POST) is a common side effect after general anesthesia with endotracheal intubation, with incidence rates reported between 7% and 90%. Topical lignocaine has been explored as a preventative measure to reduce POST.
Objective: To evaluate whether applying 2% lignocaine jelly to the endotracheal tube lowers the incidence of sore throat in patients undergoing elective surgery under general anesthesia.
Methods: In this prospective observational study, 60 patients aged 18–65 years, ASA I or II, scheduled for elective surgery were randomly assigned to two groups. Group A had their endotracheal tubes lubricated with 2% lignocaine jelly; Group B did not receive lignocaine. POST was assessed at 1, 6, 12, and 24 hours post-extubation.
Results: Group A experienced significantly fewer cases of moderate to severe sore throat at all time points (p < 0.05). No significant differences were found in the rates of hoarseness or cough between groups.
Conclusion: Applying 2% lignocaine jelly to the endotracheal tube effectively reduces the incidence and severity of postoperative sore throat.
