Abstract

Background: The procedures related to airway can be associated with increased risk of aerosolization of SARS-CoV-2 virus posing a high risk to the personnels involved. Novel methods like the intubation box have been developed to increase the safety of healthcare workers during intubation.

Methods:
In this study, 33 anaesthesiologist and critical care specialists intubated the trachea of the airway manikin (US Laerdal Medical AS) 4 times using a King Vision ® videolaryngoscope and TRUVIEW PCD TM videolaryngoscope (with and without an intubation box as described by Lai). Intubation time was primary outcome. Secondary outcomes were firstpass intubation success rate, percentage of glottic opening (POGO) score and peak force to maxillary incisors measured with a pressure sensing device.
Results: Intubation time and the pressure exerted on the incisors (detected by a click sound) were considerably higher in both groups when an intubation box was used. (Table 1) When comparing the two laryngoscopes, intubation time with the King Vision ® video laryngoscope was lower than that of TRUVIEW laryngoscope, both with and without the intubation box. (P<0.001) In both groups, rate of first pass successful intubation was higher without the intubation box, although the difference was statistically insignificant. POGO Score was not affected by intubation box but higher score was observed with King Vision ® laryngoscope. (Table 1,2).

Conclusion:
This study indicates that use of an intubation box makes intubation difficult and increases the time. King Vision ® videolaryngoscope results in lesser intubation time and better glottic view as compared to TRUVIEW laryngoscope.
