RCT of 7.5% saline in head injury

Over a thousand patients in North America with blunt traumatic head injury and coma who did not have hypovolaemic shock were randomised to different fluids pre-hospital. 250 ml Hypertonic (7.5%) saline was compared with normal (0.9%) saline and hypertonic saline dextran (7.5% saline/6% dextran 70). There was no difference in 6-month neurologic outcome or survival.
