Effect of bed height on laryngoscopy force and operator ergonomics during simulated endotracheal intubation: A randomized controlled study.

ABSTRACT:

Purpose

Excessive force during laryngoscopy for endotracheal intubation can result in injury to airway soft tissues and hemodynamic stress responses. In this randomized controlled trial on simulated intubation, we aimed to evaluate the effect of bed height on laryngoscopy force and operator ergonomics. This study was registered on Clinical Research Information Service (CRIS) registry (KCT0006948).

Methods

Fifty operators with varying levels of experience were enrolled to intubate an airway mannequin at two different bed heights- anterior superior iliac spine (level A) and xyphoid process (level X) of each operator-in a randomized sequence. The laryngoscopy force measured with a Pliance® pressure sensor attached to the surface of the Macintosh laryngoscopy blade, intubation c
