Group Intervention Description KingVision videolaryngoscope KingVision videolaryngoscope In this group intubation attempt is carried out with KingVision videolaryngoscope with a channeled, disposable single-use blade. Macintosh laryngoscopy Direct laryngoscopy In this group intubation attempt is carried out with a standard Macintosh (size 3 or 4) direct laryngoscopy blade. VividTrac videolaryngoscope Vividtrac videolaryngoscope In this group intubation attempt is carried out with VividTrac Adult model using a smartphone or laptop running the VividVision proprietary software.
- Primary Outcome Measures
Name Time Method Intubation time Measured once during the intubation attempt. Up to 120 seconds following the start of intubation attempt. Time necessary to secure airway during the induction of general anesthesia. Intubation time is measured from the point the airway device crosses the interdental line until the completion of intubation with insufflated cuffed endotracheal tube (secured airway).
- Secondary Outcome Measures
Name Time Method Percentage of glottic opening (POGO) score Registered once during the intubation attempt. Up to 120 seconds following the start of intubation attempt. The POGO score describes the best view of the glottic opening compared to the anatomical picture of the glottis. During direct laryngoscopy the investigator registers an approximate socre, while video laryngoscopy records are assessed by an independent investigator.
Tube insertion time Registered once during the intubation attempt. Up to 120 seconds following the start of intubation attempt. Time necessary for the operator to insert the cuffed endotracheal tube inside the proximal part of the trachea through the glottic opening. Tube insertion time is measured after the investigator finished the search for the glottic opening, achieved best view and decided to insert the tube into the trachea until the cuff is inflated and the airway is secured.
Laryngoscopy time Registered once during the intubation attempt. Up to 120 seconds following the start of intubation attempt. Time necessary to achieve best visualisation of the glottic opening.
Primary intubation attempt success rate Measured once after intubation. Up to 120 seconds following the start of intubation attempt. All intubation attempts must be finished within 120 seconds or the investigator should give up the attempt and reoxygenize the patient before another attempt. If the investigator finished within the 120 seconds time frame we assess endotracheal tube position by capnography and auscultation. The attempt is regarded successful if the tube is in the right position and the airway is secured.
