E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of this research is to demonstrate a significant reduction of at least 25% in the consumption of opioids at 48 hours of management of a serious trauma, while demonstrating the non-inferiority in terms of analgesia, in a group of patients receiving a continuous infusion of low dose ketamine compared to a group receiving a placebo. |
L’objectif principal de cette recherche est de mettre en évidence une diminution significative d’au moins 25% de la consommation d’opioïdes à 48 heures de prise en charge d’un traumatisme grave, tout en démontrant la non-infériorité en terme d’analgésie, dans un groupe de patients recevant une perfusion continue de kétamine à faible dose en comparaison à un groupe recevant un placebo. |
|
E.2.2 | Secondary objectives of the trial |
- Compare the cumulative doses of opioids administered during the first 5 days of treatment. - Compare the average VAS during the first 5 days of treatment. - Compare the rate of occurrence of delirium between the 2 groups occurring during intensive care. - Compare the rate of occurrence of complications between the 2 groups occurring during intensive care (urinary retention, nausea, vomiting, delirium, hemodynamic instability, hypertensive access, neurological distress (seizure), respiratory distress, change in liver function test ) - Compare the average sedation times between the 2 groups in intensive care. - Compare the average length of stay between the 2 groups in intensive care and in the hospital. - Compare the rate of occurrence of chronic pain at 3 months of treatment between the 2 groups using a validated questionnaire. - Compare the consumption of morphine at 3 months. |

E.5 End points |
E.5.1 | Primary end point(s) |
The total dose of sufentanil administered is postponed to 48 hours of treatment by adding the doses indicated on the self-administration device and / or of the Priméa® base in the event of continuous administration with the syringe pump. All doses of sufentanil or morphine equivalents administered in the operating room during this period or during any other anesthesia procedures are added. In the case of oral administration, the doses of oxynorm / oxycontin administered are converted into IV morphine equivalent so that they can be counted for the primary endpoint. The non-inferiority character will be judged on the comparison of the mean VAS of the first 48 hours of treatment. Patients' VAS is assessed every 4 hours using a validated standardized ruler device. This systematic assessment will be offered by the registered nurse (IDE) in charge of the patient. The target given to the patient in the self-controlled administration of sufentanil will be a 30mm VAS. |
