Clinical Trial Summary

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.


Description:

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.

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.

Outcome

Type Measure Description Time frame Safety issue
Primary The area under the broken line of NRS score The score of Numerical Rating Scale(NRS) is 0-10, the higher the score, the more severe the pain. Hour 0-48 after surgery
Primary Opioid consumption Total opioid consumption(conversion to equivalent morphine) Hour 0-48 after surgery
Secondary NRS pain scores The score of Numerical Rating Scale(NRS) is 0-10, the higher the score, the more severe the pain. Hour 0-48 after surgery
Secondary Time of first rescue analgesia The time from the end of the operation to the first rescue analgesics after the operation. Rescue analgesia refers to the analgesia according to the patient's requirements in addition to routine postoperative analgesia. Hour 0-48 after surgery
Secondary The incidence of rescue analgesia The incidence of rescue analgesia within 48h after surgery Hour 0-48 after surgery
Secondary Recovery time The time from the end of the operation to recovery(can be awakened) Day 0
Secondary The incidence of unexpected intraoperative events Unexpected events during operation include intraoperative cough, laryngeal spasm, body movement, tachycardia,decreased oxygen saturation, respiratory depression, bradycardia, hypertension and hypotension. Intraoperative
Secondary The Patient Efficacy Questionnaire (IPOQ ) scores Patient Efficacy Questionnaire (IPOQ ) scale include 13 questions , each question's score is 0-10 or 0-100%, it involves postoperative pain, mood and quality of life. The higher the score, the more severe the pain symptoms. Hour 48 after surgery
Secondary The incidence of adverse events after surgery The incidence of adverse events from the end of the operation to 48h after surgery. Including nausea, vomiting, increased secretions, dizziness, oversedation, infection,anesthetic awareness, nightmares, restlessness, pruritus, disorientation, delirium, respiratory depression, diplopia, diarrhea, intestinal obstruction, urinary retention, gastroesophageal reflux, constipation, chills, hallucinations, etc. Hour 0-48 after surgery
Secondary Pharmacoeconomic indicators Calculating incremental cost-effectiveness ratio (ICER)based on cost-effectiveness analysis. Hour 48 after surgery
Secondary Incidence of postoperative delirium The Chinese version of the 3D-CAM scale is used for the diagnosis of delirium, and the assessment will be carried out at 24h, 48h and 72h after the operation. If the patient is discharged 72h after the patient is discharged, it may not be assessed. Hour 0-48 after surgery
Secondary Simple Mental State Examination (MMSE) Scale score The total score of Simple Mental State Examination Scale (MMSE) is 30,the higher the score, the better the cognitive function. Hour 48 after surgery
Secondary Hospital Anxiety and Depression (HAD) Scale score Hospital Anxiety and Depression Scale (HAD) includes anxiety measure(7questions,0-21pionts) and depression measure(7 questions,0-21pionts),the higher the score, the more severe thesymptoms. Hour 48 after surgery
