Opioid Use, Unspecified, S-ketamine
Conditions
Brief summary
The purpose of this study was to observe the effects of opioid-free anesthesia with S-ketamine on postoperative analgesia and perioperative hemodynamics in short surgical operations, and to explore the effects of S-ketamine on postoperative awakening time and extubation time, nausea and vomiting, hypoxemia, and delirium.
Interventions
S-ketamine 0.5mg/kg for induction and 0.2mg/kg/h for maintenance
Sufentanil 0.2-0.3μg/kg for induction and remifentanil 0.05-0.15μg/kg/min for maintenance
