A multicenter, randomized, open-label, active controlled pragmatic clinical trial that evaluates the safety and efficacy of S (+) -ketamine for postoperative acute pain in adults in perioperative settings.
Patients often suffer acute pain after operation ，which may affect the recovery. Opioid such as morphine is the most commonly analgesic drugs, but opioid has many obviously adverse reactions ,for example respiratory depression,circulation inhibition,tolerance, addiction, nausea, vomiting, pruritus, etc. S (+) - ketamine has been described to decrease acute pain and opioid consumption,but it needs to confirm for chinese patients undergoing surgery.
Objective:Evaluate the efficacy and safety of S (+) - ketamine on acute perioperative pain for chinese adult patients,and look for the best dosage, mode of administration, timing, and compatibility ,as well explore the effect of S (+) - ketamine on postoperative delirium,anxiety ,depression and cognitive dysfunction.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| S (+)-Ketamine group | Experimental | Drug: Conventional therapy + S (+)-Ketamine In principle, there are no specific restrictions on the dosage, mode of administration, timing, and compatibility of S-ketamine hydrochloride injection,but the recommended dosage is given, which is lower than the dosage specified in the instructions. Recommended use and dosage of S (+)-Ketamine:
|
|
| Control group | Active Comparator | Drug: Conventional therapy Receiving conventional therapy without S (+)-Ketamine hydrochloride injection. There is no restrictions in drugs, doses and incompatibility, the researchers can choose appropriate medication regimens based on clinical practice, but other NMDA receptor antagonists are not be allowed to use, such as dextromethorphan and amantadine. |
