Clinical Trial Summary

This prospective study aims to evaluate the effectiveness of intraoperative DEX for postoperative analgesia and recovery after non-intubated VATS. In addition, the investigators observe the impact of DEX on anesthetic requirements, hemodynamic parameters, and adverse events during non-intubated VATS.

Description:

The non-intubated thoracoscopic approach has been adapted for use with major lung resections. The non-intubated VATS tries to minimize the adverse effects of tracheal intubation and general anesthesia, such as intubation-related airway trauma, ventilation-induced lung injury, residual neuromuscular blockade, and postoperative nausea and vomiting. An adequate analgesia allows VATS to be performed in sedated patients and the potential adverse effects related to general anesthesia and selective ventilation can be avoided. Dexmedetomidine (DEX), a highly selective alpha-2 receptor agonist, is increasingly used in anesthesia with sedative, hypnotic, anxiolytic, sympatholytic, and analgesic effects. It can also attenuate perioperative stress and inflammation and preserve the immunity of surgical patients, which may contribute to reduced postoperative complications and improved clinical outcomes. This study aims to evaluate the effectiveness of intraoperative DEX for postoperative analgesia and recovery after non-intubated VATS. In addition, the investigators observe the impact of DEX on anesthetic requirements, hemodynamic parameters, and adverse events during non-intubated VATS.
