Overview
Brief Summary
Tracheal stenosis is a serious complication following prolonged intubation. There are important differences in the challenges of airway management. This study consists of our anesthesia management experience in patients with unusual placement of tracheal stenosis due to Covid-19 undergoing tracheal dilatation.
Detailed Description
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.

Outcomes
Primary Outcomes
PCO2
Time Frame: PCO2 value at baseline just before entubation, peroperative 5, 15, 30, 45 minutes after induction, and before the extubation through surgery completion
blood partial pressure of carbondioxide
PO2
Time Frame: PO2 value at baseline just before entubation, peroperative 5, 15, 30, 45 minutes after induction, and before the extubation through surgery completion
blood partial pressure of oxygen
Secondary Outcomes
- length of intubation due to Covid-19 Pnomonia(postoperative period (up to 1 year))
- EtCO2(EtCO2 value at baseline just before entubation, peroperative 5, 15, 30, 45 minutes after induction, and before the extubation through surgery completion)
- Myers-Cotton grading scale (1/2/3)(before the surgery)
- VAS (Visual Analogue Scale) score (between 0 to 10 points)(during surgery through surgery completion)
- sPO2(SPO2 value at baseline, peroperative 5, 15, 30, 45 minutes after induction, and before the extubation through surgery completion)
