| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this study is to determine the influence of intra-operative use of remifentanil versus fentanyl on the percentage of patients with chronic pain one year after cardiac surgery.;Secondary Objective: -percentage of patients with chronic thoracic pain and their mean NRS scores three months and six months after cardiac surgery. - effect on the quality of life (QoL) and on the use of analgesics three months, six months and one year after surgery - pain thresholds will be measured, evaluating the difference in postoperative pain threshold (three days and one year after surgery) compared to preoperative pain threshold (baseline), using quantitative sensory testing. - other aspects in the postoperative period, e.g. NRS scores, postoperative consumption of analgesics, length of ICU- and hospital stay, safety parameters of remifentanil - influence of genetic variances involved in pain sensitivity (e.g. GCH-1, WDF-4, ZNF, MC1R) and in pharmacokinetics and pharmacodynamics of opiates (e.g. UGT, MRP, OPRM1, COMT) will be investigated. - cost-effectiveness analysis alongside the RCT with a 12 month follow-up will be performed. ;Primary end point(s): The percentage of patients reporting chronic thoracic pain one year after cardiac surgery. ;Timepoint(s) of evaluation of this end point: one year after cardiac surgery | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - The percentage of patients reporting chronic thoracic pain three months and six months after cardiac surgery - The mean NRS score of patients with chronic thoracic pain three months and six months after cardiac surgery. - The quality of life (QoL) three months, six months and one year after surgery. - The difference in postoperative pain thresholds three days and one year after cardiac surgery compared to the preoperative pain threshold (baseline) - The use of analgesics three months, six months and one year after cardiac surgery. - The percentage of patients with at least one NRS-score of = 4 at rest during ICU and hospital stay - The mean NRS per patient at rest during ICU stay - The required amounts of analgesics (morphine/paracetamol) during hospital stay - Length of ICU and hospital stay - Total administered amount of remifentanil and fentanyl - Total medical costs during one year, including costs of hospitalization days (ICU and non-ICU) and costs of medications - Productivity costs during one year (i.e., foregone paid and unpaid work and reduced productivity while at work) - Cost-effectiveness, expressed as incremental costs per case of chronic pain at 12 months after cardiac surgery avoided and incremental costs per quality-adjusted life-year (QALY) gained - Safety parameters of remifentanil; such as nausea, constipation, respiratory depression, duration of ventilation, hallucinations, delirium, Glascow Coma Scale, renal function) - Genetic variances involved in pain sensitivity (e.g. GCH-1, WDF-4, ZNF, MC1R) and pharmacokinetics and pharmacodynamics of opiates (e.g. UGT, MRP, OPRM1, COMT) ;Timepoint(s) of evaluation of this end point: peri- and postoperative period, 3 months, 6 months and 1 year after cardiac surgery | — |
