Method Evaluation Study of Truview Picture Capture Device(PCD) Versus MacIntosh Laryngoscope

The unexpected difficult intubation is, like the difficult mask ventilation, a feared complication to anaesthesia.

A difficult intubation occurs in approx. 1.2 - 3.8 percent of all anaesthesias .

The standard procedure of intubation in Denmark is to use the curved Macintosh blade. This method, however, has some limits, as it requires a direct view of the area of the vocal cords. For that reason we are looking for new methods of intubation that can give a better overview.

The Truview PCD™ laryngoscope is a commercially available laryngoscope with an integrated optical lens that can be connected to a camera head, and gives a better view of trachea during intubation under a general anaestetic. Furthermore it is possible to connect 8-10 liters of oxygen per minute to the Truview PCD™ laryngoscope, which will prevent fog on the viewtube and slow down the rate of desaturation.

Inclusion criteria

• Patients older than 18 years of age who are to undergo a surgery at the ENT department, Aalborg Hospital.
• Patients who understand and accept the trial information.
• SARI score 2-5.

Exclusion criteria

• SARI score 0-1 and > 5.
• A need for acute initiation. (By acute initiation the endotracheal tube will be placed in trachea during the first laryngoscopy without prior spraying with local anesthesia).
• If unexpected difficulties during the initiating anesthesia arise, the trial will be interrupted, and the patient will be treated according to the department's guidelines for the situation
