- Primary Outcome Measures
Name Time Method Proportion of patients with intolerance symptoms in the comparison groups immediately during anesthesia emergence until extubation (=T3). <br>Tolerance behavior: defined as absence of gagging, coughing, defensive movements of the extremities, tachycardia > 20% of resting value, and persistent apnea/patient-ventilator dyssynchrony.
- Secondary Outcome Measures
Name Time Method Insertion time of supraglottic airway devices (SGA) (=T1) during anesthesia induction with the number of placement attempts, gastric insufflation after successful anesthesia induction and placement of SGA (=T2).<br>Hoarseness, dysphagia, oropharyngeal pain recorded with NRS and blood traces after anesthesia in the recovery room (=T4).
