Application of intracranial hypertension animal model of brain death replication

The waveform is stable , there are adaptive to vote , without anesthetics , and high-dose barbiturates and are therefore a good method to confirm brain death . This study found that 343 * held in Victoria in intracranial pressure 2min Ⅳ, Ⅲ appear first wave latency , amplitude decreased , along with the wave disappeared, and the dollars signs of recovery , consistent with the reported J. Change the description of the function of these brain stem is irreversible disappeared. EEG showed , lO ~ 30min brain electrical activity disappeared. This is the awareness of brain function has been confirmed disappeared . Both brain pathology and cerebellar tonsil cerebellar tonsil herniation hernia medulla oblongata , the brain and brainstem have even distorted the overall shift , and brain death autopsy material j pour consistent. In another paper of brain death has been reported after light and electron microscopy in brain tissue pathological changes typical of l9, l0J. These results indicate that brain death does occur animals . The model for the study of brain death and brain neuropathology outside the various organs and changes in metabolism and structure of the foundation . Of brain death on cardiac function in the process of preliminary observation, found that abrupt increase in intracranial pressure , the heart rate slows down after a brief post- accelerated,[link widoczny dla zalogowanych], high blood pressure, consistent with those reported lI, which shows the short term after brain death in heart function is still Be . In the intravenous infusion of norepinephrine and artificial respiration to maintain the passive breathing ,[link widoczny dla zalogowanych], the heartbeat can be maintained long time, and interrupt the rescue measures, rapid heart failure, cardiac arrest ,[link widoczny dla zalogowanych], it is difficult recovery, and clinical performance of similar cases of brain death , its causes Is greater brain Described above in the loss of heart function after central nervous system regulation ,[link widoczny dla zalogowanych], although in artificial conditions may be temporarily retained , but can not prevent subsequent failure. Therefore, this animal model of function and general pathology from the reproduction of the clinical occurrence of primary brain death and heart failure cases must prove that effectively simulate the brain death , brain death to further explain the concept of death as a viable individual .
