Comparison of Preoperative Nebulization with 4% Lignocaine and Ketamine in Reduction of Incidence of Postoperative Sore Throat

Postoperative sore throat (POST) is a common occurrence following general anesthesia with endotracheal intubation although clinicians often regard it as a minor complication. The incidence of POST is estimated to be 21%-65% in different studies. The administration of the drug through aerosol route gained popularity among anesthesiologists with good acceptance from the patients. Hence, we conducted the study with the aim to compare the efficacy of preoperative nebulization with 4% lignocaine and ketamine, in the prevention of POST.
