About This Study
S-ketamine is often administered as a part of multimodal analgesia to reduce postoperative pain and postoperative opioid consumption. Current data indicates that ketamine may be useful for patients with prior use of opioids whereas the benefit for opioid-naive patients is less clear. However, different opioids have variable pharmacokinetic characteristics. Therefore, it is important to evaluate S-ketamine's effect on the pharmacokinetics of opioids.
