About

With the continuous strengthening of the concept of rapid rehabilitation, great progress has been made in minimally invasive thoracic surgery, and thoracoscopic surgery has developed rapidly. Double-lumen endotracheal(DLT) intubation is still the most reliable way of intubation in lung surgery. However, hypoxemia faced during double-lumen intubation still threatens the perioperative safety of thoracic surgery patients. In recent years, high-flow nasal oxygenation (HFNO) has great potential in the field of anesthesia, especially playing a new and important role in the prevention and treatment of short-term hypoxia and life-threatening airway emergencies. However, the use of HFNO in pulmonary surgery patients with poor pulmonary function lacks evidence-based basis, and there are few reliable clinical data.

This study adopted a prospective, randomized, controlled, single-blind design. A total of 100 patients aged 18-60 years who underwent elective thoracoscopy-assisted pulmonary surgery were included and randomly divided into the experimental group: HFNO was used in the process of double-lumen intubation asphyxia; the control group: according to the traditional intubation process, No oxygen therapy equipment was used during intubation asphyxiation. The lowest blood oxygen saturation during intubation, the incidence of hypoxemia during intubation, perioperative complications, and postoperative hospital stay were compared between the two groups.

This study explores the advantages of HFNO in complex endotracheal intubation, assuming that HFNO can improve the oxygen saturation of double-lumen intubation; optimize the intubation method of DLT, and tap its new potential to prevent and manage emergency airway crisis.
