I-scoop vs. C-Mac D-Blade Videolaryngoscope for Airway Management Under Spontaneous Breathing and Analgosedation

The purpose of this clinical trial is to investigate whether the videolaryngoscope i-scoop makes airway management under spontaneous breathing and analgosedation more clinically practicable than the established standard device, the C-Mac D-Blade videolaryngoscope, in adults undergoing surgery under general anesthesia. The main questions it aims to answer are: • Is good clinical practicability - defined as a successful, easy, and complication-free intubation under spontaneous breathing - more frequently achieved with the i-scoop than with the C-Mac D-Blade? Researchers will compare the standardized airway management procedure under spontaneous breathing using either the i-scoop or the C-Mac D-Blade. Participants will: * continue breathing on their own during the procedure * be randomly assigned (1:1) to one of the two videolaryngoscopes * receive standardized analgosedation and topical lidocaine anesthesia of the upper airway before the breathing tube is placed * be asked about discomfort and recall of the procedure after surgery (in the recovery room, on postoperative day 1, and at 7 days post-intubation) by a blinded interviewer
