Abstract

Objective: To compare small and large size endotracheal tube utilization with and without intravenous lignocaine on the occurrence of postoperative sore throat among women who have undergone elective thyroid surgery in Tertiary Care hospital, Karachi. Study Design: Randomized Control Trail. Setting: Department of Anesthesia, Civil Hospital, Karachi. Period: Six Months from 09-11-21 till 09-05-22. Methods: In this research, 204 patients in an elective thyroid surgery were utilized. Such patients were randomized in four groups, 51 in group A (ETT size 7.0 with saline); 51 in group B (ETT size 6.0 with saline); 51 in group C (ETT size 7.0 with lidocaine ad 51 in group D (ETT size 6.0 with lidocaine). Quantitative and qualitative data were gathered and displayed and examined. Post stratification chi square test was used with p-value of 0.05 as significant. Results: The mean age of the patients was 40.22+5.19 years. Group D showed a significantly lower rate of POST than Group A (23.53% vs.58.82%, P=0.0005), B (23.53% vs. 39.22%, P = 0.088) and C (23.53% vs. 43.14%, P = 0.036). Conclusion: The use of lignocaine with large size endotracheal tubes resulted in fewer episode of postoperative sore throat.
