Study Overview
Brief Summary
The purpose of this study is to estimate the effect of an early induced hypernatremia protocol (150-155 milliequivalent/L) versus normonatremia plus mannitol (135 - 145 milliequivalent/L) in terms of neurologic outcome in patients with severe traumatic brain injury managed at critical care unit.
Detailed Description
Severe traumatic brain injury is one of the main causes of death in young people. Additionally, it is considered a public health problem because of the high prevalence of motor and cognitive dysfunction in those who survive.
One of the cornerstones of management is the control of both intracranial pressure and brain edema. It is indicated to use osmotic active solutions to modulate the transit of fluids from the interstitial to the intracellular space. Not only mannitol but also hypertonic saline acts at this point. Currently there is no evidence in favor or against one of them.
Mannitol has been usually recommended for intracranial pressure control in patients with brain trauma. However, others recommend hypertonic saline to achieve a serum sodium level of 160 milliequivalent/L to modulate brain edema. It is not clear if these therapies have an impact on the neurologic prognosis and how frequently adverse effects occur.

Outcomes
Primary Outcomes
Glasgow Outcome Scale Extended
Time Frame: 6 months
The Extended Glasgow Outcome Scale (GOSE) is a global scale for functional outcome that rates patients into eight categories. The categories of severe disability, moderate disability and good recovery are subdivided into a lower and upper category. The scale will be used to evaluate the patient through a phone interview at 6 months of the trauma occurred. The structured interview contains nineteen specific questions which determine upper or lower levels of disability.
Secondary Outcomes
- All-cause mortality(28 - day AND 180 - day mortality)
- Fluid balance.(5 days)
- Ventilator - Free Days(30 days)
- Acute kidney injury(7 days)
- Need of second line therapies for brain edema(7 days)
- Intracranial pressure (ICP) measurement(5 days)
- All-cause mortality according to subgroups of monitoring: guided by neurologic examination and serial CT imaging or guided by intracranial pressure monitoring.(28 - day AND 180 - day mortality)
- Glasgow Outcome Scale Extended (GOSE) according to subgroups of monitoring: guided by neurologic examination and serial CT imaging or guided by intracranial pressure monitoring.(6 Months)
