When administered to a patient having an acute ischemic stroke, tPA has been demonstrated to reduce long-term disability.

The hippocampus is the most oxygen-sensitive part of the brain. It is well-known that severe anoxia results in profound neuronal cell death.  Generalized and/or focal brain atrophy most frequently occurs in the hippocampus, the most oxygen-sensitive region of the brain.

A medication error is a preventable event that can cause patient harm. ED medication errors are derived from prescribing, transcribing, preparation, and dispensing.

Speaking generally, when chemical exposures cause medical sequelae, the duration of the claimed exposure is a factor (along with the quantitative extent of exposure and route of absorption) that may be determinative of whether a causal link exists.

Automated dispensing cabinets [ADCs], such as Pyxis systems, are the most widely used medication safety technology.

When patients are admitted to an inpatient service from the ED and no inpatient beds are immediately available for the patient, the patient may spend hours in the ED waiting for the inpatient bed. This is termed ED boarding.
