“…438 A randomized controlled trial comparing a videolaryngoscope combined with a flexible bronchoscope reported a greater first attempt success rate with the combination technique than with a videolaryngoscope alone (Category A3-B evidence). 439 Observational studies indicated successful intubation with combination techniques ranging from 80 to 90% [440][441][442][443][444][445] and first attempt success rates ranging from 50 to 100% of anticipated difficult airway patients [440][441][442]446 (Category B3-B evidence). Case reports also observed successful intubation occurring with various combinations of techniques (Category B4-B evidence).…”

“…Evidence shows that a video laryngoscope improves the visualisation of the larynx, making intubation easier. [ 3 4 ] However, several studies have shown that intubation time with McGrath MAC ® is the same or even longer than conventional Macintosh blade. [ 5 6 7 ] Inserting the endotracheal (ET) tube through the vocal cords is more difficult despite good visualisation.…”

Background and Aims: Video laryngoscopy highly improves the success rate for endotracheal intubation. However, commercially available video laryngoscopes such as McGrath MAC ® can be costly. An economical video laryngoscope was assembled by attaching a fibreoptic videoscope into a Macintosh laryngoscope. This randomised study aimed to compare the intubation time of this self-assembled modified Macintosh video laryngoscope (SAM-VL) and McGrath MAC ® (McGrath). Methods: This study enroled 62 adults scheduled for elective surgery under general anaesthesia with endotracheal intubation. The primary outcome was total intubation time. Secondary outcomes were the time for glottic visualisation (time A), time for tube insertion after glottic visualisation (time B), first-attempt intubation success rate, degree of glottic visualisation, and need for backward, upward, rightward pressure (BURP) assistance, complications, and user satisfaction. The tests used were: Kolmogorov-Smirnov and the Mann-Whitney test to analyse the data’s distribution and the primary outcome, respectively. Results: The median total intubation time in the SAM-VL group versus the McGrath was 63 s (27–114s) versus 74 s (40–133s), respectively ( P = 0.032). Intubation time B was significantly faster, while the score of glottic visualisation and BURP assistance was significantly higher in the SAM-VL group. The differences in the rate of successful first attempts and complications were not statistically significant. SAM-VL users rated the ease of blade insertion and manoeuvrability, degree of glottic visualisation, and overall rating as very high. Conclusion: Endotracheal intubation using self-assembled modified video laryngoscope is faster and allows better glottis visualisation than McGrath MAC ® .
