The study aims to test the relationship between the preoperative pain threshold and the intraoperative need for opioids.
The objective of the study is to try to predict a patient's analgesic needs based on their objectively determined preoperative pain threshold.
The investigators will include patients scheduled for elective cardiovascular surgery.
The investigators will investigate the correlation between the preoperative pain threshold and intraoperative/postoperative opioid consumption in a highly standardized anesthesia setting.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| pain threshold arm | Other | In this arm, patients get a measure of their minimal pain threshold in the preoperative time, that is the only intervention they get in addition of the classic care support |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Measure of the minimal pain threshold with an algometer | Device | The measure of the minimal pain threshold is taken the day before the cardiac surgery |
|
| Measure | Description | Time Frame |
|---|---|---|
| Correlation between the pressure pain threshold and the consumption of opioid during and after the surgery | After the measure of the minimal pain threshold the day before the surgery, the investigators look at the quantity of Remifentanil which has been given to the patient during the surgery. Then they will look for a correlation | From enrollment to the end of opioid administration during hospital stay, up to 6 days after the enrollment |
| Measure | Description | Time Frame |
|---|---|---|
| Correlation between the pain threshold and the consumption of morphine during the post-operative time | After the measure of the minimal pain threshold the day before the surgery, the investigators look at the quantity of morphine which has been administrated by a PCA (Intravenous Patient-Controlled Analgesia (IV-PCA) with morphine) to the patient during the post-operative time. Then they are looking for a correlation. |
