Validation of the MASCAN Score to Classify Difficult Mask Ventilation During General Anesthesia for Surgery

What this Trial Is About

Researchers are evaluating the MASCAN Score, an objective tool developed to classify difficult facemask ventilation. This observational study aims to validate the MASCAN score in patients undergoing general anesthesia for surgical procedures. It also examines how different techniques, such as the timing of neuromuscular blocking agents and manual versus controlled facemask ventilation, influence outcomes. Secondary goals include assessing the diagnostic value of visual capnography curve evaluations and comparing the first attempt success rates during tracheal intubation as reported by the airway operator and an independent observer. Participants will undergo measurement of primary and secondary outcome parameters during the induction of anesthesia. The study focuses on patients receiving general anesthesia with facemask ventilation before tracheal intubation. Various ventilation parameters, airway events, and intubation details are recorded within one hour of induction to gather comprehensive data. During the study, participants will be monitored for factors such as difficult facemask ventilation, capnograph quality, ventilation mode changes, oxygen saturation levels, and airway-related adverse events. Researchers will evaluate intubation attempts, success rates, glottic view, and post-intubation recommendations. The study involves informed consent and includes patients aged 18 years or older scheduled for surgery requiring facemask ventilation and tracheal intubation. Participation involves close observation and data collection during anesthesia induction and airway management.
