Airway Management During Unusual Tracheal Stenosis

Tracheal stenosis is a serious complication following prolonged intubation. Two types of tracheal stenosis; Glottic and subglottic stenoses have common features in that they are challenging in terms of ventilation, oxygenation and intubation. However, there are important differences in the challenges of airway managementA thinner tube may be sufficient to overcome the airway difficulty in glottic stenoses. However, in subglottic tracheal stenosis, a thinner tube may not be conveyed to the distal of the stenosis. As a result, adequate ventilation and oxygenation may not be provided with an intubation tube placed proximal to the trachea. This study consists of our anesthesia management experience in patients with unusual placement of tracheal stenosis due to Covid-19 undergoing tracheal dilatation.
