Visualization of the Intubation Pathway With the "IRRIS"-Device

Status Completed

Clinical Trial Summary

A prospective, open label, non-randomized, single centre safety and feasibility study. Patients with no expected airway difficulties scheduled for elective surgery including tracheal intubation and general anesthesia procedures will be enrolled into the study. Following standard induction of anesthesia, the IRRIS will be attached to the patient's neck skin just beneath the laryngeal prominence (Adam's apple) and the intubation will be performed by using a video-laryngoscope in a standardized fashion. The IRRIS device emits a light that penetrates through the skin into the airway and that is visible on the video-laryngoscope display. This light highlights the right pathway for the tracheal tube and facilitates the visual recognition and identification of the laryngeal inlet. In case of problems identified during the induction period such as an unexpected difficult intubation situation and the IRRIS does not provide the expected facilitation of intubation, the local "unexpected difficult airway" protocol goes into effect.

Clinical Trial Description

The IRRIS (InfraRed - Red Intubation System) is an external disposable light source in a patch that is intended for single use while it is placed externally on the patient's neck before tracheal intubation for the duration of tracheal intubation. The device transmits near-infrared light through the skin towards the trachea. During laryngoscopy, the emitted light becomes visible only from the trachea and not from the oesophagus. Video assisted devices which already are in the market known as video-laryngoscopes and fiberoptic bronchoscopes are capable of detecting and visualizing the emitted light so that the anaesthesiologist who is performing the intubation is aided to direct and insert the endotracheal tube into the trachea by following the light on the screen of his video-assisted endoscope. The objective of this study is to assess the safety, and performance of IRRIS in patients who undergo tracheal intubation in terms of skin integrity, duration of intubation, number of attempts, success of intubation and usability aspects in terms of subjective physician grading of the IRRIS. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
