Evaluation of Video Laryngoscopes in Difficult Airway

Multicenter Study Evaluating Video Laryngoscopes: The Swiss Video-Intubation Trial (SWIVIT I)

In this multicenter study the investigators are going to evaluate the use of six different videolaryngoscopes in patients undergoing elective surgery requiring general anesthesia with intubation. The investigators are hypothesizing that these six videolaryngoscopes will succeed for intubation at first attempt in at least 90% of all cases using a difficult airway simulation with extrication collars. As gold standard, a standard Macintosh blade is being used.

The study consists of 6 arms. Each arm includes 120 patients, sums up to a total of 720 patients.

Inclusion Criteria:

• elective surgery with general anesthesia requiring intubation
• >18years old
• ASA I-III

Exclusion Criteria:

• known or presumed difficult airway
• risk of pulmonary aspiration
• refusing to participate
