Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients requiring general anesthesia with transoral tracheal intubation for elective surgery
  • Age ≥ 18
  • Preoperative airway assessment reveals an expected difficult airway (rated by the responsible anesthetist in the Pre-assessment Clinic based on the existing in-house algorithm)

You may not qualify if:

  • Pregnant or breastfeeding woman
  • Confirmed indications for awake fiberoptic intubation especially due to enoral, pharyngeal tumors, abscesses or other processes
  • Planned endotracheal intubation without deep anesthesia or neuromuscular blocking agents (e.g. awake videolaryngoscopy)
  • Required transnasal tracheal intubation (e.g. for surgical reasons)
  • Requirement of special endotracheal tubes such as laser or RAE tubes for surgical reasons
  • Patients at risk for pulmonary aspiration who qualify for rapid sequence induction
  • Loose teeth
  • Denial of consent
