Feasibility of real-time videolaryngoscopy streaming to operating room monitors: An observational study

Streaming the intubation procedure performed with a videolaryngoscope (VL) to operating room monitors has been rendered possible through technical improvements. This study explored the impact of streaming McGRATH MAC+™ VL live intubations to operating room monitors on team dynamics, situational awareness and evaluated overall perceptions of the device in daily practice. This cross-sectional, observational study was conducted between February and November 2025 at the Lausanne university hospital (CHUV) in Switzerland. Operating room professionals with exposure to McGRATH MAC+™ streaming completed a paper-based questionnaire assessing perceived changes in awareness, participation, communication, and device performance. Retrospective within-subject comparisons (before vs after streaming ratings) were analysed. We enrolled 50 participants (37 anaesthesia, 13 operative). After the introduction of VL streaming, awareness of the intubation process was perceived to have improved by the anaesthesia staff (p < 0.001) and the operative staff (p = 0.005). The participants didn’t perceive a significant change in their participation to the intubation with VL streaming. Secondary outcomes highlighted facilitated intra-team communication within anaesthesia teams and modestly improved inter-team coordination. No meaningful changes were reported regarding perceived intubation time or complication rates. In addition, VL was considered highly effective for training and improved operator confidence. Streaming videolaryngoscope live intubations to operating room monitors resulted in higher retrospectively perceived situational awareness and the device was viewed as an educational asset. Selective use in difficult or teaching cases may offer a high-yield strategy for enhancing team coordination during airway management. clinicaltrials.gov : NCT06453525
