1 -- Isotonic (0.9% normal saline) or slightly hypertonic (Lactated Ringer’s) IV solutions are used in the patient with LOC. Hypotonic solutions (such as 0.45% saline, D5W and D5W in 0.45% normal saline) will cause fluid to move into the cells and worsen cerebral edema. Highly hypertonic solutions will cause fluid to move out of the cells.
