Scientists from the University of Tennessee Health Science Center and also the Regional Medical Center at Memphis are going to be teaming up in order to do a national clinical study pertaining to brain injuries. This new clinical trial will actually be sponsored by the National Institute of Health. The researchers will inject a concentrated salt solution into the veins of patients who have sustained a traumatic brain insult. The scientists think that using concentrated salt solutions as opposed to the currently standard saline solutions may be able to less the amount of swelling of a person’s brain. Brain swelling can be very dangerous and any method to reduce this could improve patient outcomes.
