Do you know what subarachnoid hemorrhage is?

Anyone who has studied medicine knows that subarachnoid hemorrhage is an important knowledge that must be mastered, because it is a common disease and a necessary test point for various trainings and exams. No matter at school or after work, our first reaction is to rule out subarachnoid hemorrhage as soon as we hear the patient say that he has a sudden severe headache.

Typical manifestations of subarachnoid hemorrhage: unbearable severe headache, frequent nausea and vomiting, and soon there will be disturbance of consciousness, so many people come to the emergency department with severe headache, so there are treatment statistics. About 97% patients will suddenly have thunderous pain, which many people describe as the most severe headache in their lives. You can imagine the extent of this headache. It should be emphasized here that cerebral hemorrhage is not suitable for the elderly.

The main cause of spontaneous arachnoid hemorrhage is 75%-80%, which is caused by the rupture of cerebral aneurysm, such as congenital cerebrovascular malformation, hypertension and arteriosclerosis. Whether it is cerebrovascular malformation or arteriosclerosis, blood vessels are more fragile than normal people, just like balloons, and fragile places are easy to rupture. Then, under the inducement of overwork, emotional excitement and rapid increase of blood, blood vessels will appear once they rupture.

Causes of young people and the elderly: for young people, many are congenital cerebrovascular malformations; For middle-aged and elderly people, some of them are congenital cerebrovascular malformations. They didn't get sick when they were young, and then they got sick when they were old. There is also a large part, that is, cerebral arteriosclerosis and fragile blood vessels. When blood pressure fluctuates violently, blood vessels suddenly burst, causing arachnoid hemorrhage. What about research?

How to prevent it: Friends with hypertension should pay attention to changing bad living habits, controlling blood pressure and keeping blood pressure stable, so the brain damage caused by this disease is relatively extensive, so the harm is relatively great. In terms of treatment, it is mainly to reduce intracranial pressure, stop bleeding and maintain vital signs. Then, if there are surgical conditions, operate as soon as possible. According to the guidelines for diagnosis and treatment of subarachnoid hemorrhage in China, there are many treatment methods at present, but unfortunately, the patients with spider web hemorrhage are still poor after being cured, the mortality rate is as high as 45%, and the growth rate of survivors is relatively high. Therefore, we still need to improve our understanding of this disease, pay attention to prevention in our lives, and know when we need emergency medical treatment.
