Evaluation of the SaCoVLM, a novel third-generation video laryngeal mask: a prospective observational pilot study

The laryngeal mask airway ( LMA ) is a well-established device for securing the airway, typically inserted using a blind technique. However, blind insertion may result in suboptimal alignment and the need for reinsertion, which can increase the risk of adverse events. Therefore, in this pilot study, we aimed to conduct a preliminary evaluation and gather initial clinical experience with the new video laryngeal mask, SaCoVLM™. In this prospective observational study, the SaCoVLM™ was used for airway management in patients undergoing general anaesthesia. We assessed key quality parameters commonly used to compare the performance of different laryngeal masks. Primary outcome was first attempt success rate. Secondary outcomes were time to achieve adequate ventilation, oropharyngeal leak pressure (OLP), and the incidence of adverse events. A total of 50 patients undergoing general anaesthesia were enrolled. The first-attempt insertion success rate was 96%. The mean time to achieve adequate ventilation was 13± 2.4 s, and the mean OLP was 38± 3.8 mbar. The overall incidence of adverse events related to video laryngeal mask usage was 6%, with no serious adverse events observed. The SaCoVLM™ appears to be a promising alternative for airway management in patients undergoing general anaesthesia, demonstrating favourable performance across key clinical parameters.
