Brain injury as a result of oxygen deprivation either due to hypoxic or anoxic mechanisms are generally termed hypoxic/anoxic injuries (HAI). Hypoxic ischemic encephalopathy ( HIE ) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply, but the deprivation is not total.
The brain sustains irreversible injury after about 20 minutes of ischemia. [4] Even after blood flow is restored to the brain, patients can experience hours-days of hypotension, hypoxemia, impaired cerebrovascular autoregulation , brain edema, fever, hyperglycemia and/or seizures which further insult brain tissue.

Brain injury; Other names: Brain damage, neurotrauma: A CT of the head years after a traumatic brain injury showing an empty space where the damage occurred, marked by the arrow: Specialty: Neurology: Symptoms: Depending on brain area injured: Types: Acquired brain injury (ABI), traumatic brain injury (TBI), focal or diffuse, primary and secondary
A New Scientist article from 2000 gives a pair of graphs [15] showing changes of patient status during the first 12 months after head injury and after incidents depriving the brain of oxygen. [16] After a year, the chances that a PVS patient will regain consciousness are very low [ 17 ] and most patients who do recover consciousness experience ...
Short latency EPs such as SSEP, VEP, and BAEP can be used to indicate prognosis for traumatic and anoxic brain injury. Early after anoxic brain injury, no response indicates mortality accurately. In traumatic brain injury, abnormal responses indicates failure to recover from coma. In both types of injury, normal responses may indicate good outcome.
Rick Kern/Getty Images Matthew McConaughey is all smiles despite having one eye swollen shut from a bee sting. “Bee swell,” McConaughey, 54, captioned his Instagram post on Wednesday, July 10 ...
A bee sting is the wound and pain caused by the stinger of a female bee puncturing skin. Bee stings differ from insect bites, with the venom of stinging insects having considerable chemical variation. The reaction of a person to a bee sting may vary according to the bee species. While bee stinger venom is slightly acidic and causes only mild ...
