tracheal tug

 

Definition:

  1. a downward pull of the trachea, manifested by a downward movement of the thyroid cartilage, synchronous with the action of the heart and symptomatic of an aneurysm of the aortic arch; the sign is elicited most easily by drawing the cricoid cartilage upward with the thumb and forefinger while the patient sits with head thrown back and mouth closed;
  2. a jerky type of inspiration seen when the intercostal muscles and the sternocostal parts of the diaphragm are paralyzed by deep general anesthesia or muscle relaxants; due to the unopposed action of the crura's pulling on the dome of the diaphragm and thence on the pericardium, lung roots, and tracheobronchial tree during each inspiration.
