A simple method for rat endotracheal intubation.

Abstract

A simple, fast, reliable, and atraumatic method of endotracheal intubation was developed to provide long-term mechanical ventilation in rats. Light from a focused point source directed to the outside of the skin just anterior to the pharyngoepiglottic region penetrated the skin, muscles and trachea and allowed direct visualized placement of an endotracheal tube.
