Prediction of Chronic Pain by the Pain Monitor (D3C)
|ClinicalTrials.gov Identifier: NCT01595711|

The skin conductance algesimeter (Pain Monitor™, Med-Storm Innovation AS, NO-0264 Oslo, Norway)) reflects the sympathetic nervous system by the measurement of the skin conductance of the palm of the hand. SCA detects nociceptive pain fast and continuously, specific to the individual, with higher sensitivity and specificity than other available objective methods.
The skin conductance response to a calibrated noxious stimulus varies among patients. It defines two types of people depending on its magnitude.
The investigators assume that the importance of skin conductance response to a noxious stimulus predicts the occurrence of chronic pain in patients operated by thoracotomy.

Measurement of cutaneous conductance
- Prediction of chronic pain [ Time Frame: one year after surgery ]Prediction of chronic pain by the measurement of skin conductance
- Prediction of the postoperative pain [ Time Frame: 5 days postoperatively ]Prediction of the postoperative pain by the measurement of skin conductance. Postoperative pain is assessed (pain score) at least twice each day at rest and during mobilisation.
- Prediction of the postoperative antalgic requirement [ Time Frame: 5 days postoperatively ]Prediction of the postoperative analgesic requirement by the measurement of skin conductance. The analgesic requirement is evaluated by the amount of epidural analgesics.
- Prediction of the postoperative antalgic requirement by the genetic study [ Time Frame: One year after surgery ]Prediction of the postoperative antalgic requirement by the genetic study
- Effect of remifentanil on skin conductance [ Time Frame: One hour after anesthesia ]Skin conductance is measured before and after a calibrated noxious stimulus. This test is performed after the induction of anesthesia (propofol) and a first time before remifentanil administration and a second time after.
