NCT02421913

Brief Summary

Background: The use of low-dose continuous infusion of S(+)-ketamine combined with target-controlled intravenous anesthesia with remifentanil and propofol may be related to the control of postoperative pain and of opioid-induced hyperalgesia. The present study aimed to evaluate the efficacy of continuous infusion of S(+)-ketamine given intraoperatively in the control of postoperative pain compared to placebo.
