Traumatic brain injury (TBI) frequently leads to elevated intracranial pressure and cerebral edema. Selecting the appropriate first-line intravenous osmotic agent is a critical early decision that directly affects ICP control and neurological outcomes.
Patient with traumatic brain injury presenting with elevated intracranial pressure or cerebral edema requiring acute osmotic management. Patient-specific factors — including electrolyte status and volume status — inform agent selection within this protocol.
Initial management centers on intravenous osmotic therapy. Hypertonic sodium solutions are the preferred first-line intravenous agent. The protocol specifies an effective intravenous alternative for patients in whom the primary agent cannot be used, with clear criteria guiding the switch — the complete selection algorithm and decision criteria are in the full regimen.
We suggest using hypertonic sodium solutions over mannitol for the initial management of elevated ICP or cerebral edema in patients with TBI (conditional recommendation, low-quality evidence).
We suggest that the use of mannitol is an effective alternative in patients with TBI unable to receive hypertonic sodium solutions (conditional recommendation, low-quality evidence).
While the overall quality of the evidence in this area is low, the panel felt there was enough consistency across the published studies to suggest that both HTS and mannitol are effective in reducing ICP elevations and cerebral edema.
