Early Effects of Enteral Urea on Intracranial Pressure in Patients With Acute Brain Injury and Hyponatremia.
Hyponatremia occurs commonly after acute brain injury and is often due to the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Urea administration is 1 therapeutic option. ⋯ Enteral urea administration in patients with acute brain injury and hyponatremia is associated with a significant reduction in ICP independent of changes in sodium levels.

Observational StudyPostoperative Delirium in Elderly Patients Undergoing Major Spinal Surgery: Role of Cerebral Oximetry.
Perioperative cerebral hypoperfusion/ischemia is a major inciting factor of postoperative delirium, which is coupled with adverse outcome in elderly patients. Cerebral oximetry enables noninvasive assessment of the regional cerebral oxygen saturation (rSO2). This study aimed to investigate whether perioperative rSO2 variations were linked to delirium in elderly patients after spinal surgery. ⋯ The degree and duration of decrease of the perioperative rSO2 measurements were not associated with delirium in elderly patients after spinal surgery.
