Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Proportion of patients with intolerance symptoms in the comparison groups immediately during anesthesia emergence until extubation (=T3). 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
| Measure | Time frame |
|---|---|
| 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). Hoarseness, dysphagia, oropharyngeal pain recorded with NRS and blood traces after anesthesia in the recovery room (=T4). | — |
