Critically ill patients or patients under prolonged unconsciousness need a tube inserted into their windpipe to provide oxygen. This tube, called a tracheostomy tube, can be connected to a ventilation device to allow the patient to breathe when they cannot do it for themselves. In the hospital, doctors will perform a percutaneous tracheostomy (PT), where a needle is inserted through the skin of the neck into the windpipe, providing a guide for a tube that will dilate the tissue and create a hole that the tracheostomy tube can be inserted into. Although this is a common procedure in critical care units, it does carry some risks to the patient and is not always successful. The needle may puncture the back or side of the windpipe if it is inserted too far, or it can miss the windpipe altogether, causing damage to surrounding structures. We believe that doctors who perform PT would benefit from a method that improves the success rate of the procedure. We wish to test a device that alerts the doctor performing PT to when the needle tip is in the air-filled windpipe. The device has been proven to aid needle insertion in cadavers, but it needs to be tested on live patients. Since many intensive care patients undergo PT, we wish to test our technique on this population. It will be a controlled environment and the clinicians are experienced in PT. This technique should save valuable time, result in more accurate needle insertion, and lessen the risk of damaging other structures and tissues in the neck.

Further study details as provided by University of Alberta:

Primary Outcome Measures:
  • Speed and accuracy of needle tip placement in the tracheal lumen [ Time Frame: From positioning of the patient to withdrawal of needle; approximately 5 minutes ]
    The speed and accuracy with which a needle/catheter assembly connected to a nerve stimulator is inserted through the cricothyroid membrane into the tracheal lumen will be measured.
