Pediatric hypertonic saline use in emergency departments

Published:September 28, 2018DOI:https://doi.org/10.1016/j.ajem.2018.09.040
      Hypertonic saline (HTS) is often used to manage cerebral edema and increased intracranial pressure (ICP) in children via creation of an osmolar gradient which promotes decreases in brain interstitial volume along the blood-brain barrier [
