Transfusion of Blood Products in the Neurocritical Care Unit: An Exploration of Rationing and Futility.
Rationing is the allocation of scarce resources, which in healthcare necessarily requires withholding potentially beneficial treatments from some individuals. While it often entails a negative connotation, rationing is unavoidable because need is limitless and resources are not. ⋯ At the core of any rationing, decision is how much a limited resource may benefit a patient, which can be particularly difficult to determine in the practice of neurocritical care, as prognosis is often uncertain. We present a case for the consideration of futility and blood product rationing in neurocritical care.

Patients with posterior fossa lesions causing obstructive hydrocephalus present a unique clinical challenge, as relief of hydrocephalus can improve symptoms, but the perceived risk of upward herniation must also be weighed against the risk of worsening or continued hydrocephalus and its consequences. The aim of our study was to evaluate for clinically relevant upward herniation following external ventricular drainage (EVD) in patients with obstructive hydrocephalus due to posterior fossa lesions. ⋯ Radiographic presence of upward herniation was often present prior to EVD placement. Clinically relevant upward herniation was rare, with only two patients worsening after the procedure, in the presence of other clinical confounders that likely contributed as well.

The First CT Scan of the Brain: Entering the Neurologic Information Age.
Computed tomography (CT) scan of the brain transitioned clinical neurology from the educated-guess world to the real computer-age world. One of the first CT scans-published by the British neuroradiologist James Ambrose-showed an intracranial hemorrhage and also suggested the use of iodine to demonstrate abnormal blood-brain barrier. ⋯ CT scanning of the brain has revolutionized diagnostic acute neurology and neurosurgery and was the overture to an even larger revolution-magnetic resonance imaging. This historical vignette discusses the development of CT scanning of the brain and its connection with neurocritical care.
