   Medical scientists have rediscovered that ischemia and hypoxia can lead to brain death. If rescued in time, it is possible for the brain to be re-perfused with blood and nutrients within a certain period of time, and it is possible to restore its function and avoid brain death.

   In summary, there is a time lag in brain death. During the rescue, it is right to use the machine to rescue brain cells. If the machine has been on for a long time but the patient has not been able to resume spontaneous breathing and heartbeat, the brain is dead, and the person is always dead.

The    brain death debate then goes back to how long this time difference is. This time difference is the reason for the great collision of various views in society. If you cannot scientifically determine the length of the time difference for a specific individual, it is possible to misjudge the death of the patient.

  In statistics, some big data cannot be specifically classified into individuals. Some people have a longer time difference, and some people have a shorter time difference. Don't underestimate this time difference of one minute and one second, it can really kill life and death.

   In order for brain death to have sufficient factual proof, we must go back to the original point. Doctors want to find evidence that the patient's brain is dead, not just talk about time.

  In the past, neurologists have expertise in this area and are the most suitable people to find evidence to determine whether a patient is brain-dead. The problem is, the problem of insufficient clinical manpower is all too common. In order to make up for the lack of manpower and inconvenience, the international practice is to set the judgment standard of brain death. No specialist doctor is needed, only a clinician can be competent after short-term training and passing the qualification examination.

   At this point, some people may doubt whether non-neurologists can judge brain death.

   There is no need to be nervous about this. In fact, the determination of brain death is a process, and it is the same process as the determination of patients with cardiac death. There is a rule in the criteria for judging brain death: the cause of the patient must be identified, and it is clear that irreversible brain damage causes brain death.

   This level requires the deep involvement of neurosurgeons and cannot be ruled out.

   Having said that, we can understand why Cao Yong insisted on sending his child to a specialized hospital like Fang Ze. Obviously want to prevent omissions in all aspects. With the most professional team of neurologists, we can try our best to avoid medical imprecision that leads to misjudgment of the child's condition.

   This answered some of Cao Zhao's suspicions, and at the same time heard an answer from his brother's words that he thought but didn't want: "Do you think this child may have been brain dead at that time?"

   "I was at the scene, what else could I have except a flashlight and a cotton swab?" Cao Yong was amused.

   Didn't he say it at first? Making a medical diagnosis is a very rigorous thing. Although he is a doctor, he doesn't have a see-through eye. How can he see what the child's brain injury is?

   "Do CT, and do CT more than once." Cao Yong tapped on the key points he said.

   Don't take the fact that their uncle revealed on the phone that the CT initially showed that the child had injured the brain stem as the final result.
