Study of changes in perfusion index to assess stress during intubation compared with standard measures in adult patients undergoing gall bladder removal surgery.

Change in perfusion index as a novel indicator for measuring stress response in laryngoscopy and endotracheal intubation and its comparison with conventional parameters of stress response in american society of anesthesiologists grade 1 and 2 patients undergoing elective laparoscopic cholecystectomy. - Nil

Design outcomes

Primary

MeasureTime frame
Change in perfusion index from baseline at the time of laryngoscopy. Timepoint: From baseline to till 10 minutes.—

Secondary

MeasureTime frame
To examine how the perfusion index varies with factors such as the patients age, the length of the surgical procedure, and the type of non depolarizing muscle relaxant used. To explore the relationship between perfusion index and changes in heart rate and blood pressure and to compare how accurately perfusion index reflects stress response compared to traditional hemodynamic measures. Timepoint: From baseline to till 10 minutes.—
