Question 6#

Which of the following is FALSE regarding hypertonic saline?

A. Is an arteriolar vasodilator and may increase bleeding
B. Should be avoided in closed head injury
C. Should not be used for initial resuscitation
D. Increases cerebral perfusion

Correct Answer is B

Comment:

Hypertonic saline (7.5%) has been used as a treatment modality in patients with closed head injuries. It has been shown to increase cerebral perfusion and decrease intracranial pressure, thus decreasing brain edema. However, there also have been concerns of increased bleeding because hypertonic saline is an arteriolar vasodilator.
