Abstract
ETT obstruction due to shearing of the plastic sheath of the stylet has been reported in the past with small endotracheal tubes (ETT) (1, 2). We report a similar case of partial obstruction with a 4.5mm armored ETT. To the best of our knowledge, this is the first report of shearing of the plastic-coated stylet that occurred with an armored ETT. We believe that endotracheal tube stylets should be inspected after each use.
