Abstract

A comparative study of laryngoscopic views and blade to tooth distance obtained using non-dominant vs dominant hand for laryngoscopy for patients undergoing surgery under general anaesthesia - a one year randomized clinical trial”

BACKGROUND: Literature search did not reveal any study comparing the laryngoscopic views using dominant hand vs non dominant hand for laryngoscopy and endotracheal intubation. Hence, we make an attempt to compare laryngoscopic views and blade to tooth distance on laryngoscopy with dominant or non-dominant hand using respective laryngoscope blades for endotracheal intubation in patients undergoing general anaesthesia. Our null hypothesis is that both dominant and non-dominant hand are equally effective in obtaining glottic view on laryngoscopy. OBJECTIVES: Primary objective: To compare laryngoscopic views and blade to tooth distance on laryngoscopy with non-dominant or dominant hand using respective laryngoscope blades in patients undergoing general anaesthesia. Secondary objective: To note the time required for endotracheal intubation on laryngoscopy with non-dominant or dominant hand using respective laryngoscopic blades in patients undergoing general anaesthesia
