An Evaluation of Retrograde Light-Guided Laryngoscopic Intubation and its Comparison with Conventional Direct Laryngoscopic Intubation in Emergency OT.

This study compares Retrograde Light-Guided Laryngoscopic (RLGL) intubation with Conventional Direct Laryngoscopic (DL) intubation in emergency operating theatres. Given the challenges and varying success rates among novices performing tracheal intubations via DL, alternative methods that are cost-effective and simpler to execute are continually sought. RLGL, utilizing retrograde transtracheal light transmission, offers a promising approach by simplifying the identification of the glottis. This randomized, open-label, parallel-arm superiority trial involved 205 patients and aimed to evaluate the effectiveness and practicality of RLGL against DL, focusing on glottic exposure, intubation success rates, and the learning curve for novice intubators. Results suggested that RLGL could significantly improve success rates and reduce the time for both glottic exposure and tracheal intubation, demonstrating its potential as a valuable tool for novice intubators.
