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] [5] It differs from persistent vegetative state, in which the person is alive and some autonomic functions remain. [6]

2024年6月25日 · Brain death is when a medical condition like a stroke or a traumatic brain injury causes major and permanent damage to your brain. In brain death, you’re unconscious and you can’t breathe on your own.

2024年3月21日 · The course primarily focuses on three core areas: the etiology and progression to brain death, distinguishing brain death from other states such as coma or vegetative state, and the comprehensive criteria and protocols for the diagnosis of brain death.

2022年7月15日 · Brain death is legally recognized as equivalent to cardiopulmonary death in the United States. Brain death is defined by a strict set of criteria that, once met, confers zero likelihood of awakening from coma. The final common pathway of brain death is shown below.

2024年8月2日 · Brain death is a clinical and legal definition of death. A person who is brain dead may still show signs of life such as warm skin, a heartbeat, and a chest that rises and falls with ventilation. Even though a brain-dead person may appear to be alive, the brain is significantly damaged and recovery is impossible.

Brain death signifies the complete, irreversible cessation of brain function, including the capacity for the brainstem to regulate respiratory and vegetative activities. It was first described in 1959, predating widespread organ donation, which has since made its codification critically necessary.

Brain death, also known as brain death/death by neurologic criteria, refers to a permanent loss of brain function that cannot resume spontaneously and cannot be restored by medical interventions. Function of the entire cerebrum and brain stem is lost, resulting in coma, no spontaneous respiration, and loss of all brain stem reflexes.

There is a clear difference between severe brain damage and brain death. The physician must understand this difference, as brain death means that life support is futile, and brain death is the principal prerequisite for the donation of organs for transplantation.

2017年11月7日 · To help clinicians make a brain death diagnosis, The Johns Hopkins Hospital in June 2016 created a Determination of Death by Neurological Criteria Support Team. Here’s how it works: A patient arrives in the emergency room after an overdose, car accident or other trauma that caused extensive brain injury.

2024年3月21日 · Brain death occurs after the destruction of enough neuronal cells in the brain that there is both an irreversible loss of consciousness (coma) and the absence of brainstem reflexes, including the inability of the lungs to inhale and exhale without external positive pressure support (apnea).
