确定脑死亡的案件确认检测的成年人

脑死亡的确定是基于全面的临床评估。诊断测试,至少在成年患者在美国国家不是强制性的,但它通常被用作维护或添加在临床检查时发现不习惯地不完整。在其他国家,确认测试是强制性的;在许多,他们是可选的。这些测试可以分为那些测试大脑的电功能和那些测试脑血流量。(即假阳性结果。,the test result suggests brain death, but clinically the patient does not meet the criteria) is not common but has been described for tests frequently used to determine brain death. A false-negative result (i.e., the test result suggests intact brain function, but clinically the patient meets the criteria) in one test may result in more confirmatory tests and no resolution when the test results diverge. Also, pathologic studies have shown that considerable areas of viable brain tissue may remain in patients who meet the clinical criteria of brain death, a fact that makes these tests less diagnostic. Confirmatory tests are residua from earlier days of refining comatose states. A comprehensive clinical examination, when performed by skilled examiners, should have perfect diagnostic accuracy.
