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.
Interventions
Anesthesia management in patients with subglottic tracheal stenosis with flow-controlled ventilation using an intubation tube with an inner diameter of less than 3 mm

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| PCO2 | 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 | 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
| Measure | Time frame | Description |
|---|---|---|
| sPO2 | SPO2 value at baseline, peroperative 5, 15, 30, 45 minutes after induction, and before the extubation through surgery completion | peripheral oxygen saturation |
| EtCO2 | EtCO2 value at baseline just before entubation, peroperative 5, 15, 30, 45 minutes after induction, and before the extubation through surgery completion | end-tidal carbondioxide measurement |
| VAS (Visual Analogue Scale) score (between 0 to 10 points) | during surgery through surgery completion | surgeons' satisfaction(VAS 0=the worst view, 10= the best view) |
| Myers-Cotton grading scale (1/2/3) | before the surgery | The grade of tracheal stenosis |
| length of intubation due to Covid-19 Pnomonia | postoperative period (up to 1 year) | time from intubation to extubation in ICU |
