Brainstem death is a clinical syndrome defined by the absence of reflexes with pathways through the brainstem – the "stalk" of the brain, which connects the spinal cord to the mid-brain, cerebellum and cerebral hemispheres – in a deeply comatose, ventilator -dependent patient. Identification of this state carries a very grave prognosis for ...
Maternal somatic support after brain death occurs when a brain dead patient is pregnant and their body is kept alive to deliver a fetus. It occurs very rarely internationally. Even among brain dead patients, in a U.S. study of 252 brain dead patients from 1990–96, only 5 (2.8%) cases involved pregnant women between 15 and 45 years of age.
The test is commonly used by physicians, audiologists and other trained professionals to validate a diagnosis of asymmetric function in the peripheral vestibular system. Calorics are usually a subtest of the electronystagmography (ENG) battery of tests. It is one of several tests which can be used to test for brain stem death.
Researchers said on Monday they have for the first time mapped the changes that unfold as a woman's brain reorganizes in response to pregnancy, based on scans carried out 26 times starting three ...
For the first time, researchers have mapped out the very real physical changes of “pregnancy brain,” the changes that a mother’s brain undergoes while carrying a baby.. There’s “so much ...
Microchimerism. During pregnancy, a two-way traffic of immune cells may occur through the placenta. Exchanged cells can multiply and establish long-lasting cell lines that are immunologically active even decades after giving birth. Microchimerism is the presence of a small number of cells in an individual that have originated from another ...
15,000 to 20,000. Brain death is the permanent, irreversible, and complete loss of brain function, which may include cessation of involuntary activity necessary to sustain life. [1][2][3][4] It differs from persistent vegetative state, in which the person is alive and some autonomic functions remain. [5] It is also distinct from comas as long ...
Lazarus sign. The Lazarus sign or Lazarus reflex is a reflex movement in brain-dead or brainstem failure patients, [1] which causes them to briefly raise their arms and drop them crossed on their chests (in a position similar to some Egyptian mummies). [2][3] The phenomenon is named after the Biblical figure Lazarus of Bethany, [4] whom Jesus ...
