Use of 10% lignocaine spray in adenotonsillecotmy surgery for post-operative pain and cough.

Abstract

Objective: To determine the efficacy of 10% lignocaine spray for preventing post-operative cough and pain for adenotonsillectomy surgery. Study Design: Quasi Experimental study. Setting: Department of Anesthesia, Armed Forces Hospital Jazan, Saudi Arabia. Period: March 2024 till August 2024. Methods: A total of 140 patients with age from 4-12 years scheduled for adenotonsillectomy were equally divided in two groups. After intubation in group L, one puff of 10% lignocaine on each side was sprayed over the tonsils. Similarly at the end of the surgery lignocaine puff was repeated on each side in the same manner. However in group N, instead of lignocaine spray, normal saline spray was done in similar manner. All patients were observed for persistent coughing. All patients were also observed for pain using Modified Objective Pain Scale. Any patient with score of 5 or more was given rescue analgesia. Results: In group L, only 11 (15.71%) out of 70 patients experienced cough while in group N, 16 (22.85%) patients experienced cough post-operatively. This difference was insignificant (p-value 0.284). In group L, median and interquartile range for modified objective pain score was 1 and 3 respectively whereas it was 1 and 2 for group N. In group L, less patient’s i-e 5 only received rescue analgesia whereas 8 patients in group N received rescue analgesia but this difference was in significant (p-value 0.382). Conclusion: It is concluded in our study that 10% lignocaine spray does not reduce the incidence of post-operative cough and has no effect on post-operative pain scores as compared to the normal saline spray.
