The Emerging Role of Ketamine in Acute Postoperative Pain Management.

Several randomized controlled trials found that the use of ketamine either alone or in combination with other medications leads to decreased postoperative pain and opioid consumption. However, there are other studies that have not found these benefits. The results as of now suggest that the role of intraoperative ketamine in postoperative pain control varies among different operative procedures. While some studies have shown promise in ketamine's potential use as a postoperative analgesic, there is still a great deal of proposed research and randomized controlled trials needed to deduce the most efficacious and tolerable form and dose of ketamine.
