A Prospective Observational Crossover Study Comparing Intubation by Pediatric Residents Using Video Laryngoscopy and Direct Laryngoscopy on a Pierre Robin Simulation Manikin.

INTRODUCTION: Video laryngoscopy (VL) has been proposed to increase the likelihood of successful intubation in patients with predicted difficult airways such as those with Pierre Robin sequence (PRS). Prior studies have focused on the performance of anesthesiologists, who are generally considered airway experts. Our primary aim was to investigate the success rate of intubation using VL compared with direct laryngoscopy (DL) when attempted by pediatric residents on a PRS model. METHODS: Participants were administered a 5-minute refresher video on 2 VL techniques (CMAC, conventional geometry VL, and McGrath, unconventional geometry VL) and DL. The participants were asked to intubate the AirSim PRS infant manikin. The order of VL and DL use was randomly selected. All intubations were video recorded, and the recordings were analyzed by 3 anesthesiologists blinded to the participant's identity and previous experience. RESULTS: Seventeen of 23 residents succeeded in intubating the PRS model using DL. Only 9 residents succeeded in intubating the PRS model using VL (conventional or unconventional geometry). Intubation success rate was higher when comparing DL with VL ( P = 0.04) and similar when comparing VL devices ( P = 0.69). DISCUSSION: Contrary to expectation, the intubation success rate was lower using VL than with DL among pediatric residents. This should be considered when designing residency training and in real-life resuscitation.

The rapid development of AmboVent: a simple yet sustainable ventilation solution for use in a pandemic.

INTRODUCTION: COVID-19 (SARS-CoV-2) emerged at the end of 2019, generating a rapidly evolving pandemic, raising serious global health implications. Among them was the fear of a mechanical ventilator shortage due to COVID-19's high contagion rate and pathophysiology. Fears of a ventilator shortage unleashed a wave of innovations. MATERIAL AND METHOD: This manuscript describes the AmboVent, a ventilator, rapidly developed with a sense of urgency, by a group of Israeli volunteers. RESULTS: Using a decentralized approach, we worked extensively and managed within ten days to create a working ventilator. It utilizes a 64-year-old technological concept, the bag valve mask (BVM), sometimes known by the proprietary name Ambu bag, which we transformed into an automatic, controlled, and feature-rich ventilator by endowing it with contemporary computing technology. CONCLUSIONS: Applying a functional rather than a commercial-oriented approach can result in the ad hoc development of lifesaving solutions during a rapidly spreading pandemic.
