What are the advantages and disadvantages of using hypothermia after cardiac arrest?

Podchrana after the heart pledge cools the body and reduces the demand of the brain for oxygen. The use of this treatment significantly improved the subsequent functioning of the brain in patients who were revived after cardiac arrest and reduced mortality. Without treatment, the brain is deprived of oxygen and suffers from damage. This therapy is not recommended for all patients with heart arrest. The increased risk is involved in patients who also have head damage, patients who are already in a coma, patients who bleed and others. One of the main disadvantages for cardiac patients is that therapy is not in extensive use. Many hospitals and doctors do not use the induced hypothermia but gain acceptance and use. Successful programs require all aspects of the medical team, from emergency medical technicians to intensive staff for employees to be coordinated in the use of hypothermia for cardiac arrest. Another disadvantage is that this is not suitable treatment for all who suffer from cardiac arrest.

Patients experiencing sudden cardiac arrest may have their heart rhythm restarted, but cannot quickly gain consciousness. This is because the blood supply during and after cardiac arrest was not sufficient for the brain to function properly. Medical research has found that the lowering body temperature to 89 to 93 ° Fahrenheit (32-34 ° C) reduces the demand of the brain for oxygen. Cooling is performed quickly and the patient is maintained in an induced hypothermic coma for up to 24 hours. This allows organ and brain to recover more than if the patient was at normal temperatures.

One study compared the results of patients who underwent therapeutic hypothermia after cardiac arrest with patients who do not. After six months, three areas of concern were compared for both groups - brain performance, mortality and complications. In the hypothermia group, there was a significant positive difference in the function of the brain and reducing mortality. The level of complications did not differ significantly between the two groups.

TechnoloGIE has shown significant benefits and many doctors and scientists believe it is unethical to continue studies that deny one group of patients therapeutic hypothermia. The hospitals that use this technology see a convincing difference in the brain function after sudden cardiac arrest. Before using therapeutic hypothermia after cardiac arrest, only a small percentage of patients recovered full or acceptable brain function. In the treatment of yes, estimated half of patients with cardiac arrest.
