First-attempt success rate of video laryngoscopy in small infants (VISI): A multicentre, randomised controlled trial

The Lancet Dec 18, 2020

Garcia-Marcinkiewicz AG, Kovatsis PG, Hunyady AI, et al. - In this multicentre, parallel group, randomised controlled trial, researchers ascertained if video laryngoscopy with a standard blade done by anaesthesia clinicians improves the first-attempt success rate of orotracheal intubation and decreases the risk of complications when compared with direct laryngoscopy. The sample consisted of infants without difficult airways abnormalities requiring orotracheal intubation in operating theatres at four quaternary children's hospitals in the USA and one in Australia. Patients (1:1) were randomly assigned to video laryngoscopy or direct laryngoscopy using random permuted blocks of size 2, 4, and 6, and stratified by site and clinician role. Five hundred sixty-four infants were randomly assigned [282 (50%) to video laryngoscopy and 282 (50%) to direct laryngoscopy] between June 4, 2018, and August 19, 2019. Among anaesthetised infants, the use of video laryngoscopy with a standard blade improves the first-attempt success rate and decreases complications.
