  Purpose

Various medical procedures require different objects to be inserted into the airway; for example, a bronchoscope - a fibreoptic camera device - can be guided down the windpipe to gain real-time images of the airway. Since inserting objects down the throat is uncomfortable for most patients, doctors have several options, one of which is putting the patient to sleep using general anesthetic before inserting something into the windpipe. This may not always be the best option, especially in cases where the patient needs to be awake during the procedure. In these cases, the doctor may 'freeze' the windpipe before inserting a scope or a tube into the airway. For this, the doctor inserts a needle through the front of the neck and injects local anesthetic. Inserting a needle into the windpipe comes with some risks to the patient, and the doctor wants to avoid puncturing nearby structures, such as arteries, veins, and the esophagus. The investigators have come up with a new method for accurately guiding a needle into the airway that will alert the user when they have successfully placed the needle tip in the windpipe. The investigators hypothesize that this new method will prove to be beneficial to clinicians and emergency medical personnel who need a fast, easy, and reliable way to insert a needle into the airway.


Condition Intervention
Transtracheal Injection
Fibreoptic Intubation
Procedure: Transtracheal injection

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Official Title: Adaptation of Nerve Stimulation Technology to Aid Transtracheal Needle Insertion and Injection

Further study details as provided by University of Alberta:

Primary Outcome Measures:
  • Needle tip placement in tracheal lumen [ Time Frame: From positioning of the patient to anesthesia of the trachea; approximately 10 minutes ] [ Designated as safety issue: No ]
    After injection of local anesthetic into the skin of the neck, a needle connected to a syringe containing 4-6 mL 2-4% lidocaine will be inserted through the cricothyroid membrane into the tracheal lumen. Success will be recorded as accurate puncture of the cricothyroid membrane and trachea and injection of lidocaine into the tracheal lumen.
