A comparison of McGrath video laryngoscope versus macintosh laryngoscope for intubation undergoing general anesthesia: a meta-analysis.

ABSTRACT:

Background

Unexpected difficult intubation during general anesthesia can significantly increase patient morbidity and mortality. The McGRATH videolaryngoscope is recognized for its ability to enhance laryngeal visibility in patients with both difficult and normal airways. This study aims to compare the efficacy of McGrath videolaryngoscopes and Macintosh laryngoscope in adult patients under general anesthesia, utilizing data from prospective randomized trials.

Methods

A comprehensive literature search was performed across databases including PubMed, Web of Science, and Embase. Data on the success rate of the first intubation attempt, intubation time, and glottic visualization during tracheal intubation were extracted from the identified studies. The data were analyzed using
