Awake extubation response: comparison of superior laryngeal nerve block andin line nebulisation with lgnocaine- a randomised controlled study

Abstract

ABSTRACT Introduction Extubation is the critical phase of anaesthetic management that can trigger significant stress responses in the form of hemodynamic fluctuations. These responses are mediated by the stimulation of the larynx and trachea, leading to sympathetic nervous system activation. Effective management of extubation stress is crucial for patient safety and comfort. This study aims to compare the efficacy of superior laryngeal nerve block versus in-line nebulization with lignocaine in mitigating extubation responses in surgical patients. Objectives Primary objective of the study is to compare the hemodynamic stress response post-extubation in the form of HR, SBP, DBP and MAP and secondary objective is to grade the severity of post-operative cough and postoperative sore throat at different time interval post-extubation between the group receiving superior laryngeal nerve block and in line nebulisation with lignocaine.
