Abstract

To evaluate the effect of intravenous bolus administration of 23.4% saline (8008 mOsm/L) on refractory intracranial hypertension (RIH) in patients with diverse intracranial diseases. Retrospective chart review. A neurosciences intensive care unit in a university hospital. We present eight patients and a total of 20 episodes of increased intracranial pressure (ICP) resistant to standard modes of therapy. Five patients had subarachnoid hemorrhage, one patient had traumatic brain injury, one had a brain tumor, and another had spontaneous basal ganglia hemorrhage. Seven patients had intraventricular catheters, and one had a subarachnoid pressure screw placed. We monitored continuously mean ICP, serum sodium concentrations, mean arterial pressure, cerebral perfusion pressure (CPP), central venous pressure, and urine output before and after the administration of hypertonic saline (HS). Post mortem examination of the brain was performed in two patients. Intravenous bolus administration of 30 mL of 23.4% saline. There was a significant (p < .05) decrease in ICP from a median of 41.5 mm Hg before HS to 17 mm Hg at 1 hr, 16 mm Hg at 2 hrs, and 14 mm Hg at 3 hrs after HS administration. In 80% of cases, ICP decreased by >50% of the pretre...Continue Reading

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.

Brain Injury & Trauma

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.
