Brief Summary

Patients with chronic pain can experience considerable changes in their cognitive function such as forgetfulness, increased absentmindedness, confusion etc. Opioids (e.g. morphine and morphine-like analgesics) are often used in treatment of acute and chronic pain and can lead to worsening of the cognitive function. The interaction between pain, treatment and cognitive function is very complex and is far from understood. The hypothesis of the present study is that by use of experimental pain in healthy volunteers it will be possible to elucidate the interaction between pain, treatment and cognitive function.

Outcome Measures

Primary Outcomes (1)

  • Cognitive function

    Investigate the relationship between cognitive function and pain and treatment with remifentanil

    3 experiments each lasting for about 4-6hours - total duration of study is around 8-9month

Study Arms (2)

Remifentanil

ACTIVE COMPARATOR

Investigate the effect of remifentanil on cognitive function in healthy volunteers by use of experimental pain models: * tonic muscle pain induced by the tourniquet pain model * cognitive tests * recording of brain activity by use of 64 channel cap

Drug: Ultiva (remifentanil) or placebo

Placebo infusion

PLACEBO COMPARATOR

To blind the study and use as comparator in the investigation of the effect of remifentanil on cognitive function in healthy volunteers by use of experimental pain models: * tonic muscle induced pain by the tourniquet pain model * cognitive tests * brain activity by use of a 64 channel cap

Drug: Ultiva (remifentanil) or placebo

Interventions

0.1microg/kg/min remifentanil administered as infusion Max infusion time is 20min

Also known as: Ultiva (remifentanil)
Placebo infusionRemifentanil
