Abstract

Background: This study aims to evaluate the effectiveness of high‐flow oxygen as the sole method of gas exchange in apneic conditions for airway management during laryngeal surgery. Methods: A prospective study was performed on 45 patients aged 30 to 69 who underwent laryngeal surgery from January 2023 to August 2023 in 108 Military Central Hospital. Patients received total anesthesia and neuromuscular blocking agents for the duration of their surgery and airway management using a high flow oxygen 70 liters/min under apneic conditions as the sole method of gas exchange. Results: The mean (SD) apnea time was 18.36 (4.97) mins, and the time for laryngeal surgery was 16.82 (4.69) mins. The oxygen saturation is stable at 99% to 100% during all procedures. A blood gas analysis showed hypercapnia and acidosis acute respiratory. However, the parameters return to normal at 30 min postoperative. The blood pressure and heart rate are stable at times. All 45 patients were safe at the end of the operation. There were no complications such as bleeding, hemothorax, pneumothorax, or barotrauma. Conclusion: Apneic oxygenation with high‐flow oxygen for airway management during laryngeal surgery is a safe and effective method for gas exchange. The surgical field is ultimately spacious, with optimal conditions for laryngeal surgery.
