![]() This is the criterion endorsed by Pope St. 1 The cessation of heart and lung function anticipated this bodily disintegration. This will help avoid unnecessary testing and provide timely family support when the diagnosis is confirmed.Traditionally, the presence or absence of bodily integration has been used to definitively discern the presence or absence of life in the human being where decomposition of the body is the surest sign of death. A collaborative interprofessional team can help accurately and efficiently diagnose the patient with brainstem death. The bedside nurse, social worker, and the clinical providers can educate the family about the process of brainstem death evaluation and the meaning of the results to help the family understand this difficult concept. The critical care nurse also assists the medical team by monitoring the patient, especially during the apnea testing, to ensure the test is terminated if unstable vital signs develop. The critical care nurse assists the clinician to make this diagnosis by verifying and documenting the neurological status of the patient before and during the brainstem evaluation. ![]() In most intensive care settings the initial examination is performed by the critical care provider. The diagnosis of brainstem death requires meticulous and verifiable testing and evaluation. Is the brain dead person really dead? - Issues in defining biological death - certain pitfalls merit consideration while evaluating for brainstem death confirmation: īecause of differences in the definition of death owing to different cultural and religious grounds, it is challenging to obtain equivocal consensus for declaring brainstem death. There can be looming fear that death will be declared prematurely for the sake of organ and tissue retrieval. Public belief in brain death and organ procurement - There can be a significant concern among the relatives and the public that organ donation occurs when the patient heart is still beating, and the person is not entirely dead. Moreover, hypercarbia by causing cerebral vasodilation can further impede upon the cascade of impending cerebral herniation, thereby further complication the clinical scenario. It is also distinct from cortical death (persistent vegetative state) wherein the brainstem functions are intact.Ĭoncerns with the apnea test - There are inherent confounding clinical factors that can invalidate the apnea test, such as hypoxia, hypotension, cervical cord injuries. It requires emphasis that though the brain stem is dead, there may still be some cortical and the hypothalamic functions (osmoregulation) intact in the patient. The whole-brain death concept - It is more prudent for the application of brainstem death rather than the whole brain death concept. Įthical morality - justifying the use of limited medical resources, adding up the financial burden, and maximizing emotional toll to relatives in a hopeless clinical scenario However, when planning for organ donation, separate complete examinations by two physicians is recommended. Whole Brain death - biological death with absent cortical and brainstem functionsĭeath - Whole-brain death along with the cardiopulmonary arrestĭemonstration of clinical signs of brain death including coma, brainstem areflexia, and apnea Persistent vegetative state - loss of only cortical functions with intact brain stem functionsīrain-stem death - absent brain stem reflexes but the presence of few cortical as well as hypothalamic integrity such as osmoregulation The American Academy of Neurology (AAN) has postulated brain death as a “coma, absence of brainstem reflexes, and apnea.” Academy of Medical Royal Colleges Working Party has defined brainstem death as 'the irreversible loss of the capacity for gaining consciousness, and the capacity to spontaneously breathe.' ![]() The revised memorandum in 1979 correlated brainstem death with death itself. The Conference of Royal Medical Colleges in 1976 came to the consensus that brainstem death constitutes brain death. Mollart and Goulon first coined the term 'coma depasse,' meaning a state beyond coma, for brain death.
