Risk Factors for Desaturation in Anesthetic Management During Airway Stenting

Area of Science:

• Anesthesiology
• Pulmonology
• Medical Devices

Background:

• Airway stenting is a procedure to treat airway stenosis.
• Anesthetic management for airway stenting is challenging due to the surgical field and the need to avoid hypoxia.
• Risk factors for oxygen desaturation during airway stenting are not well-established.

Purpose of the Study:

• To retrospectively identify risk factors associated with oxygen desaturation during airway stenting.
• To analyze clinical data to determine predictors of desaturation.

Main Methods:

• Retrospective analysis of 302 patients undergoing airway stenting under general anesthesia with controlled ventilation.
• Total intravenous anesthesia with propofol and remifentanil was used.
• Univariate and multivariate analyses were performed to identify risk factors for desaturation (SpO2 ≤ 90%).

Main Results:

• The incidence of oxygen desaturation was 18.5% (56/302 cases).
• Preoperative orthopnea (Odds Ratio [OR], 3.06) and stenosis distal to the bronchus (OR, 3.31) were identified as significant risk factors for desaturation in multivariate analysis.

Conclusions:

• Preoperative orthopnea and distal bronchial stenosis are key risk factors for oxygen desaturation during airway stenting.
• Anesthetic plans should be carefully tailored for patients with these identified risk factors to improve safety.
