Deep hypothermal circulatory collapse, also known as DHCA, was an important auxiliary method for the treatment of complex cardiovascular and cerebrovascular diseases.
This technique could stop the body's blood circulation, and objectively, it could provide surgeons with a clean, bloodless, and quiet operating field and atmosphere, which would make it convenient for the delicate completion of the surgery.
The other organs were not so "delicate." The biggest problem of the freezing technique was the damage caused by cerebral blood transfusion and transfusion, the damage to the central nervous system, and the early and long - term postoperative nervous system complications.
These factors had already become one of the most dangerous factors that affected the survival and prognosis of surgery patients. Some patients would have cerebral infarction immediately after the surgery.
As a result, the patient's quality of life after the surgery was greatly affected.
