Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The effect of intravenous ketamine administered prior to and for up to 72 hours following surgical incision on the incidence of chronic post-surgical pain at 12 months post-operatively.
Ketamine or placebo dosage is intravenous 0.5 mg/kg bolus, followed by 0.125 mg/kg/hr intra-operatively, then 0.125 mg/kg/hr continued for up to 72 hours post-operatively.

The initial bolus dose will be administered after induction and prior to surgical incision.
The trial infusion will be continued for 72 hours after the commencement of surgery, or until:
1. the patient no longer requires opioid analgesia (IV or oral) for acute pain management, or
2. IV access is discontinued by the treating surgical unit, or
3. the patient is deemed ready for discharge home by the treating surgical unit.
The research staff will liaise daily with the treating ward staff and acute pain service to coordinate trial solution administration with the patient care plan for each day.

Trial solution rate dose escalation: In the case of severe postoperative pain that is not responding adequately to standard postoperative analgesia (NRS or VAS pain score >5/10 with functional impairment of postoperative mobilization), the trial solution infusion rate can be doubled to 0.25 mg/kg/hr (ketamine or placebo equivalent) by the treating acute pain team. This should be reviewed daily and returned to the standard rate where pain control becomes satisfactory or if side effects which are considered possibly related to the study drug are found to be dose limiting.

Trial solution rate dose reduction: If the patient is experiencing symptoms such as hallucinations, unpleasant dreams, delirium, confusion or drowsiness which the research staff in consultation with the treating clinicians suspect may be due to ketamine administration and which are causing distress or impeding patient’s postoperative mobilisation or recovery, the trial solution can be ceased for 2 hours and re-commenced at half the rate administered previously.

Trial solution cessation: Following dose reduction of >6 hours, if there are persisting postoperative symptoms such as hallucinations, unpleasant dreams, delirium, confusion or drowsiness which the research staff in consultation with the treating clinicians suspect may be due to ketamine administration and which are causing distress or impeding patient’s postoperative mobilisation or recovery, the trial solution can be ceased

Dose escalation, reduction or cessation will be captured in the eCRF and be centrally monitored via the database. Site monitoring will occur early in the trial and allow for education of research staff.

1. If the trial solution is stopped or is interrupted for whatever reason by clinical staff, and upon review it is considered that the trial solution should be recommenced, this can occur.
2. Trial solution rate dose escalation: This should be reviewed at least daily, or more urgently or frequently if required, for example due to refractory severe pain or suspected side effects.

Outcomes
Primary outcome [1] 302793 0
The incidence of chronic post-surgical pain (CPSP) reported by the patient at telephone follow-up structured interview and adjudicated as CPSP by the endpoint adjudication committee. CPSP will be defined as pain reported by the patient in the area of the index surgery, experienced in the week prior to the 3 and 12 month follow up calls, which either was not present, or is different in site, nature or of greater intensity (VAS =2/10 above pre-operative pain score) than any pain present prior to surgery. Details of reported pain will be reviewed by three members of the EAC for blinded assessment of whether they meet the criteria for CPSP. EAC members will be clinicians practicing in the field of pain medicine with expertise in chronic pain assessment.

Statistical methods / analysis
Based on blinded data collected for the planned interim analysis at n = 1,500, the observed incidence of CPSP at 3 months post-surgery was approximately 24% (95% confidence interval 22% to 27%) and the observed lost to follow-up rate at 3 months post-surgery was about 4%. Using 22% as a conservative estimate of the overall incidence of CPSP at 3-months post-surgery, the power to detect an approximate 15% or 25% reduction in incidence of CPSP at 3 months post-surgery by ketamine (i.e., a decrease from 24% to 20% or 25% to 19%, or approximate RR of 0.85 or 0.75, respectively) is 82% and 99%, respectively, with a two-sided type I error of 4.9% (based on the existing alpha-spending allowance for the interim analysis performed at n = 1,500). This assumes a final sample size of 4,000 after allowing for a conservative final lost-to-follow-up rate at 3 months post-surgery of 10% by the end of the trial.
Subsequently in June 2023, top up funding has been secured in the form of NHMRC CTCS Grant 2023989 (submitted in August 2022), which will allow recruitment to continue to achieve the original target of n = 4396 patients (plus allowance for loss to follow up of up to 10% above this target as originally forecast, total n = 4,884).
Analysis will be undertaken on an intention to treat basis. The analysis set will consist of all randomised patients who underwent anaesthesia for surgery, irrespective of whether trial solution was administered during surgery or not. Analysis of the efficacy outcomes will be undertaken according to their randomised treatment assignment (i.e., “as randomised”) while analysis of the safety outcomes will be “as treated”.
If the participant is randomised and surgery is cancelled and not to return for further surgery, the patient will be withdrawn from the intention to treat analysis.

Summary
Brief summary
Chronic post-surgical pain (CPSP) is among the most common and debilitating complications of major surgery, with enormous long term costs to the economy and patients’ quality of life. Primary prevention is now seen as the “Holy Grail” of anaesthesiology. There is a well established physiological and pharmacological basis for the proposition that the widely used, potent analgesic ketamine given perioperatively reduces the development of CPSP in patients undergoing major surgery, and this is supported by meta-analysis of data from small placebo controlled published studies. The potential benefits in reducing the healthcare cost and the quality of life burden of chronic pain in the community are substantial. A large clinical trial of perioperative ketamine analgesia is urgently needed in patients undergoing general anaesthesia for major surgery. Proof of effectiveness would transform routine anaesthetic practice worldwide with huge economic and humanitarian benefits.
