What is the most appropriate intravenous fluid for a person with altered level of consciousness (LOC)?

Question

Quizplus · Accepted Answer

Isotonic or slightly hypertonic fluids (such as 0.9% saline) are the most appropriate for a person with altered LOC because they help maintain adequate cerebral perfusion and reduce the risk of cerebral edema. Packed cells may be necessary in cases of severe anemia, but do not address the issue of maintaining cerebral perfusion. Hypotonic fluids may exacerbate cerebral edema, and dextrose-containing fluids may actually worsen altered LOC by promoting a shift of water from the extracellular to intracellular compartment, causing cerebral edema.
