“…This was presumably due to the poorer views with Truview‐PCD which, in turn, might have led to increased force application by the operator in group TR. A previous manikin study has also reported difficult manipulation and more dental clicks (indicative of dental trauma in their study) in Truview‐PCD group than with Macintosh blade …”

“…A previous manikin study has also reported difficult manipulation and more dental clicks (indicative of dental trauma in their study) in Truview-PCD group than with Macintosh blade. 22 CMAC demonstrated a 100% success rate with a high first attempt success rate of 97%, while the use of Truview-PCD resulted in lesser first attempt (83%) and overall success rate (92%) for intubation.…”

Summary Background Videolaryngoscopy has an established role in difficult airway management in adults. However, there is limited literature to support their efficacy in children. The Truview Picture Capture Device has shown promising results for endotracheal intubation in infants in the past. The CMAC videolaryngoscope has launched its novel infant Miller blade, but its performance has not been assessed clinically for routine intubation in infants and neonates. We hypothesized that the CMAC videolaryngoscope would reduce the total time to intubation as compared to the Truview Picture Capture Device in neonates and infants. Methods After parental informed consent, 80 prospective infants posted for surgical procedures under general anesthesia were randomized to undergo intubation with either of the two. The two videolaryngoscopes were also compared in terms of time required for glottis view and intubation (primary outcome), modified Cormack and Lehane grade, first attempt and overall success rate, ease of intubation, number of attempts, and any complications. Results The CMAC significantly reduced the time required for glottic view [8 s (5.25‐9) vs 9 s (6.5‐12); P = 0.02] and intubation [22 s (18‐26) vs 26 s (21.5‐32); P = 0.003]. The median difference (95% CI) for time to tracheal intubation and time to glottic view was 4 s (1‐7) and 1 (0‐4). It also improved the ease of intubation, the Cormack‐Lehane grades, and first attempt success rate. Intubation with the CMAC was possible in 100% cases, whereas only 92.5% of patients could be intubated with the Truview. The failed intubations with the Truview could be successfully intubated with the CMAC. Conclusion The CMAC Miller blade reduced the total time taken for tracheal intubation and intubation difficulty as compared to the Truview Picture Capture Device and may be a better tool for intubation in infants.

“…Although many previous surveys on intubation with the AWS in comparison with the MCL or other VLs [7][8][9][10][11][12][13][14][15][16][17][18][19][20], to our knowledge, there are no reports comparing the performance of the AWS with SADs. In line with previous results, intubation with the AWS had a longer TTV than the SADs in this study.…”

“…While it is logical that a better glottic view might translate into easier or more rapid endotracheal intubation, data are conflicting as to whether video laryngoscopy results in increased intubations on the first attempt, decreased complications, or improved clinical outcomes (16, 18, 20-22). Along with the need to train operators on multiple devices, these conflicting results have limited the use of video laryngoscopy for the intubation of critically ill patients (23).…”

Objective To evaluate the effect of video laryngoscopy on the rate of endotracheal intubation on first laryngoscopy attempt among critically ill adults. Design A randomized, parallel-group, pragmatic trial of video compared with direct laryngoscopy for 150 adults undergoing endotracheal intubation by Pulmonary and Critical Care Medicine fellows. Setting Medical intensive care unit in a tertiary, academic medical center. Patients Critically ill patients ≥ 18 years old. Interventions Patients were randomized 1:1 to video or direct laryngoscopy for the first attempt at endotracheal intubation. Measurements and Main Results Patients assigned to video (n = 74) and direct (n = 76) laryngoscopy were similar at baseline. Despite better glottic visualization with video laryngoscopy, there was no difference in the primary outcome of intubation on the first laryngoscopy attempt (video 68.9% versus direct 65.8%, p = 0.68) in unadjusted analyses or after adjustment for the operator’s previous experience with the assigned device (odds ratio for video laryngoscopy on intubation on first attempt 2.02, 95% CI 0.82 – 5.02, p = 0.12). Secondary outcomes of time to intubation, lowest arterial oxygen saturation, complications, and in-hospital mortality were not different between video and direct laryngoscopy. Conclusions In critically ill adults undergoing endotracheal intubation, video laryngoscopy improves glottic visualization but does not appear to increase procedural success or decrease complications.
