Comparative Preference of Airtraq Laryngoscope Over Macintosh Laryngoscope- A Review

Abstract

Tracheal intubation using a Macintosh laryngoscope can save lives. However, because intubation is a difficult procedure to master, failures can have disastrous results. A more recent intubation tool than the Macintosh is the Airtraq optical laryngoscope, which offers glottic plane visualization without requiring correct tracheal, pharyngeal and oral axes alignment. Airtraq can improve the incidence of failed first intubations and the time required to manage an airway, especially in patients who have had cervical spine trauma which requires manual stabilization of the cervical spine. With no differences in hemodynamics or intubation duration, the Airtraq laryngoscope offered patients a better laryngeal vision than the Macintosh laryngoscope by providing shorter laryngoscopy and intubation time, and easier intubation. The aim of this literature review was to compare these two laryngoscopes with respect to endotracheal intubation. This review article was put together after a comprehensive study of the literature using the electronic databases PubMed, Medline, Embase and Google. Airtraq laryngoscope was found to be superior to Macintosh laryngoscope as it provides a better view of the glottic region with more ease and less intubation time than the conventional Macintosh laryngoscope.
