Thirst is considered as one of the most distressing symptoms experienced by patients hospitalized in the Intensive Care Unit (ICU). Whereas pain is a permanent concern for all caregivers, thirst is often ignored and its complications are poorly known. Mechanisms involved in thirst regulation are numerous and complex. To date, care of thirst is still non optimal. Critically ill patients are usually rehydrated intravenously or using a naso-gastric tube, thus shunting the mouth as a therapeutic target to relieve the patient's thirst.
Water, cold and mint applied in mouth were studied separately and were shown to decrease thirst significantly on animal models and healthy humans.
Therefore, the hypothesis of this study is that application of small mint ice cubes in mouth of very dehydrated ICU patients should allow decreasing quickly and significantly thirst for these patients, before the correction of their biological parameters, like natremia and osmolarity.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Mint ice cubes | Experimental | Physician applies 3 mint ice cubes in mouth of highly dehydrated patient. Patient undergoes an additional blood test at 5 min from mint ice cubes application. Physician performs patient's questioning before mint ice cubes application and at 5 min, 1h, 2h, 4h, 12h and 24h from mint ice cubes application. |

| Change of thirst intensity at 5 minutes from mint ice cubes application | The primary endpoint is a change of thirst intensity of at least 1.5 points on the thirst intensity scale at 5 minutes from mint ice cubes application. Thirst intensity scale is a numeric scale ranging from 0 to 10 points. 0 corresponds to no thirst (the best outcome). 10 corresponds to a thirst of the strongest possible intensity (the worst outcome). | at 5 minutes from mint ice cubes application |
| Measure | Description | Time Frame |
|---|---|---|
| Change of thirst-associated discomfort at 5 minutes from mint ice cubes application | This secondary endpoint is a change of thirst-associated discomfort on the discomfort scale at 5 minutes from mint ice cubes application. The discomfort scale is a numeric scale ranging from on a 0 to 5 points. 0 corresponds to "very comfortable" (the best outcome). 5 corresponds to "very uncomfortable" (the worst outcome). |
