Comparison of Hemodynamic Stress Response During Intubation Using Video Laryngoscope and Conventional Direct Laryngoscope

Abstract

Endotracheal intubation is associated with a significant hemodynamic stress response, 
characterized by an increase in heart rate (HR), blood pressure (BP), and catecholamine 
release. The choice of laryngoscopy technique can influence this response. This study compares 
the hemodynamic stress response between video laryngoscope (VL) and conventional direct 
laryngoscope (DL) during endotracheal intubation in patients undergoing general anesthesia.
