Abstract

The movement of liquids at the capillary level is established by Starling's theory and the movement of the solutes is regulated by the permeability of the capillaries and is based on the theory of pores in the different types of capillaries and the coefficient of reflection for the aforementioned.

The determination of fluid flow through the intact blood-brain barrier is dependent on the transcapillary osmotic pressure gradient. After an injury that compromises the integrity of the same will occur the movement, hydrostatic pressure and transcapillary coloidosmotic pressure.

When the blood-brain barrier is not damaged, we could use crystalloid solutions safely, but if it were, large volumes of such isotonic solutions could increase brain edema and it would be better to maintain hydration with colloidal solutions with less effect on edema.

Hypertonic sodium chloride solutions seem to have a better benefit than the others, their advantage over 20% mannitol has not been demonstrated, but it has been useful in treatment-resistant endocranial hypertension and in patients with severe head trauma Associated with hypovolemic shock.
