Abstract
Background: Subglottic tracheal edema is a potentially life-threatening complication associated with tracheal intubation. Prompt airway management, including a tracheotomy, is required for treatment. The aim of this study was to assess the risk of subglottic tracheal edema associated with intubation using a double-lumen intratracheal tube and the results of treatment.
Methods: We treated 6 patients who had subglottic tracheal edema after extubation with double-lumen intratracheal tubes after undergoing lung cancer surgery in our hospital between 2008 and 2016. We retrospectively collected related clinical information and treatment from chart reviews.
Results: There were 6 patients (0.9% of all patients who underwent lung cancer surgery) with subglottic tracheal edema identified (all females). All patients had undergone anatomical pulmonary resection during which a double-lumen endobronchial tube (tube diameter, 32 - 35 Fr) was inserted into the trachea. The median age was 75 years (range, 64-89 years). The tracheas tended to be narrower than the average for Japanese (10.89 mm vs. 14 mm). All patients presented with inspiratory stridor and difficulty breathing between 24 and 48 h after extubation. Bronchoscopy was performed to diagnose subglottic tracheal edema. Emergency tracheotomies were performed in 4 patients, and 2 patients were treated conservatively with steroids. All patients recovered within 1 week and were discharged from the hospital without sequelae.
Conclusion: We managed 6 patients with subglottic tracheal edema. The patients were all females, and their tracheas were narrower than the average for Japanese. Subglottic tracheal edema is a temporary, life-threatening condition. Adequate airway management is critical to maintaining airway patency in patients with subglottic tracheal edema.
