Smart glasses for monitoring vital signs in anaesthesia care settings: a qualitative simulation study.
Article in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMonitoring of vital signs is essential in anaesthesia care and plays a key role in preventing adverse events. Technological innovation is recognised as an important factor in enhancing patient safety. Smart glasses represent a novel tool that may support anaesthesia professionals in monitoring vital signs; however, their practical use and user experiences in anaesthesia care remain insufficiently explored. Understanding anaesthesia healthcare professionals' experiences with this technology is crucial to ensure its safe and effective implementation. In this study, smart glasses from Microsoft HoloLens 2 were used to visualize vital signs in the user's field of vision. The aim was to explore anaesthesia health care professionals' experience of using Microsoft HoloLens 2 smart glasses for monitoring vital signs in various simulated anaesthesia care scenarios.
methodsA qualitative study design was used to explore the experiences of nurse anaesthetists and anaesthesiologists. Data were gathered through focus group interviews and subsequently analysed using qualitative content analysis.
resultsOne overarching theme - a positive yet cautious attitude towards smart glasses - was identified, comprising three categories: Impact on intraoperative monitoring, Usability of the smart glass technology, and Communication challenges. These categories illustrated both advantages and limitations of using smart glasses in simulated anaesthesia care scenarios.
conclusionsThe experience of using Microsoft HoloLens 2 for monitoring vital signs in simulated anaesthesia care scenarios revealed a generally positive but careful attitude towards the technology. Participants appreciated its potential to enhance situational awareness through continuous access to vital signs, while also highlighting concerns related to ergonomics, restricted field of view, and possible distraction. The findings offer insights for developers aiming to optimise smart glasses for clinical use. Further refinement and evaluation in clinical settings are needed before broader implementation in anaesthesia practice.
