High-Flow Nasal Oxygen vs. Face Mask During Sedoanalgesia in Non-Intubated Thoracoscopic Pericardial Window Surgery

Sponsor: Ebru Girgin Dinc

Summary

This is a prospective, randomized, parallel-group clinical trial designed to evaluate the effects of high-flow nasal oxygen therapy (HFNOT) versus conventional oxygen mask (COM) on perioperative hypoxia in patients undergoing video-assisted thoracoscopic (VATS) pericardial window procedures under sedoanalgesia. The pericardial window procedure, indicated for diagnostic and therapeutic drainage of pericardial effusion, is traditionally performed under general anesthesia. However, the use of non-intubated VATS with sedoanalgesia has gained popularity due to reduced morbidity, shorter recovery, and avoidance of complications associated with general anesthesia, especially in elderly and comorbid patients. During non-intubated VATS, the occurrence of hypoxia and hemodynamic instability may be exacerbated by procedural pneumothorax and underlying cardiac pathology. High-flow nasal oxygen therapy may provide physiological benefits in this setting by reducing airway resistance, improving alveolar ventilation, and minimizing dead space. The primary outcome of the study is to compare the incidence of perioperative hypoxia between HFNOT and COM groups. Secondary outcomes include patient comfort, intraoperative oxygenation profiles, hemodynamic stability, and recovery parameters. The trial will be conducted at a single academic center with eligible patients randomized into two treatment arms.
