Primary Outcome Measures:
  • Effects of HS versus mannitol on lactate/pyruvate ratio [ Time Frame: 20 min, 40 min, H1, H2, H3 and H4 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Metabolic profile evaluated thanks to measure of lactate/pyruvate ratio and cerebral glucose [ Time Frame: 20 min, 40 min, H1, H2, H3 and H4 ] [ Designated as safety issue: No ]
  • Duration of PtiO2 > 15 mm Hg if PtiO2 was < 15 mm Hg before osmotherapy [ Time Frame: 20 min, 40 min, H1, H2, H3 et H4 ] [ Designated as safety issue: No ]
  • Duration of ICP<20 mm Hg after osmotherapy [ Time Frame: 20 min, 40 min, H1, H2, H3 and H4 ] [ Designated as safety issue: No ]
  • Interstitial osmolarity [ Time Frame: 20 min, 40 min and H1 ] [ Designated as safety issue: No ]
  • Necessity of a third line therapy (hypothermia, craniectomy, propofol/barbiturate coma [ Time Frame: Day after osmotherapy ] [ Designated as safety issue: No ]
  • Length of stay [ Time Frame: After leaving the unit ] [ Designated as safety issue: No ]
  • Mortality [ Time Frame: 28th days ] [ Designated as safety issue: No ]
  • Glasgow outcome scale [ Time Frame: 6th month ] [ Designated as safety issue: No ]

Detailed Description:

Mannitol is frequently used to treat intracranial hypertension after TBI. However, it can be deleterious, particularly through hyperdiuresis and risks of hypovolemia. It also needs volume compensation and induces logistical problem because of needs of high infused volume to achieve osmolar load and avoid hypotension. Finally, some recent studies tend to prove superiority of hypertonic saline versus mannitol on the prognosis of TBI. especially through modulation of inflammatory reactions mechanisms and apoptosis.

We would like to prove non inferiority of hypertonic saline versus mannitol after TBI to allow its large utilization, especially by field military doctors with specific logistical problems. For that, more than the single Intracranial Pressure, we want to study effects of HS vs mannitol not only on PtiO2 but also on cerebral microdialysis which gives informations on focal metabolism with profiles of ischemia, metabolic crisis, hyperglycolysis (possible reflect of neuronal restoration) and normality.
