Objective: To determine the frequency of sore throat in patients undergoing intubation as part of general anesthesia using intravenous dexamethasone and lidocaine before endotracheal intubation.
Methodology: In this randomized controlled trial, total of 200 patients equally divided into two groups were selected. Group A was given inj dexamethasone 8mg i/v and Group B was given inj lidocaine 1mg/kg body weight i/v. Mean ages in both the groups were 40.20+13.12 and 47.21+10.68, respectively. Patients with sore throat were mild 25(25%), moderate 28(28%) and severe 12(12%) in dexamethasone group and mild 25(25%), moderate 28(28%), severe 14(14%) in lidocaine group. Patients with no sore throat in Group A were 35(35%) and patients in Group B with no sore throat were 33(33%). We considered mild sore throat as no sore throat, this complaint is only by asking the patient according to scoring of sore throat. Chi-square test was used to compare the frequency of sore throat between two groups.
Results: The frequency and severity of sore throat in Group A (dexamethasone) was 40% and Group B (Lidocaine) was 42% (p=0.998).
Conclusion: Dexamethasone and lidocaine before endotracheal intubation reduced the frequency and severity of postoperative sore throat in patients receiving general anesthesia with endotracheal intubation. However, the difference was not statistically significant.
