A COMPARATIVE STUDY OF HEMODYNAMIC RESPONSE TO LARYNGEAL MASK AIRWAY INSERTION AND ENDOTRACHEAL INTUBATION DURING GENERAL ANESTHESIA

Abstract

Background: Airway management during general anesthesia commonly involves endotracheal intubation or laryngeal 
mask airway insertion. Endotracheal intubation is associated with marked sympathetic stimulation, whereas laryngeal 
mask airway insertion may provide better hemodynamic stability.
Aim: To compare the hemodynamic response to laryngeal mask airway insertion and endotracheal intubation during 
general anesthesia.
Materials and Methods: A prospective comparative study was conducted in the Department of Anesthesiology among 
88 patients undergoing elective surgeries under general anesthesia. Patients were divided into two groups according to 
airway management technique. Group E included patients managed with endotracheal intubation, while Group L included 
patients managed with laryngeal mask airway insertion. Hemodynamic parameters including heart rate, systolic blood 
pressure, diastolic blood pressure, and mean arterial pressure were recorded before induction and after airway 
instrumentation. Statistical analysis was performed using Student’s t-test. A p-value less than 0.05 was considered 
statistically significant.
