The immediate priority in acute canine head trauma is restoring and maintaining mean arterial pressure (MAP) to optimize cerebral perfusion pressure (CPP), calculated as CPP = MAP − ICP. Journal of Vete…

Fluid resuscitation targets systolic arterial blood pressure between 100 and 110 mm Hg, based on Brain Trauma Foundation guidelines adopted for veterinary patients. AAHA Clinical G… When hemorrhage is ongoing, packed red blood cells, plasma, and platelets are preferred over crystalloid fluids based on superior outcomes in that setting. AAHA Clinical G…

Osmotherapy is the primary tool for reducing intracranial pressure (ICP). Both mannitol and hypertonic saline (HTS) effectively lower ICP, and neither is recommended over the other. AAHA Clinical G… Mannitol is dosed at 0.5–1 g/kg IV over 15 minutes, administered through a microfilter. AAHA Clinical G… HTS (NaCl 7.2%) is dosed at 1–6 mL/kg IV over 15 minutes. AAHA Clinical G… HTS carries the additional advantages of avoiding diuresis, increasing cardiac preload, and positively impacting cerebral perfusion. AAHA Clinical G…

Head and body positioning has a clinically significant effect on ICP and must be addressed immediately as a nursing priority. Head-down positioning increases mean ICP by approximately +7.6 mmHg (+100%) in sternally recumbent conscious dogs. Journal of Vete… In standing dogs, head-down positioning produces a maximal mean ICP increase of approximately +16.5 mmHg (+180%), likely because the head can fall further below the level of the heart in that posture. Journal of Vete… Optimal head elevation reduces ICP and is a well-documented component of traumatic brain injury management. Journal of Vete…
