A Cochrane review found that it is useful in full term babies with encephalopathy. In general, cell death is not directly caused by oxygen deprivation, but occurs indirectly as a result of the cascade of subsequent events. Cells need oxygen to create ATPa molecule used by cells to store energy, and cells need ATP to regulate intracellular ion levels. ATP is used to fuel both the importation of ions necessary for cellular function and the removal of ions that are harmful to cellular function.
Therapeutic hypothermia is a type of treatment. Cardiac arrest happens when the heart suddenly stops beating. Once the heart starts beating again, healthcare providers use cooling devices to lower your body temperature for a short time.
The treatment usually lasts about 24 hours. The heart has an electrical signal that helps coordinate the heartbeat. If this signal is disrupted or abnormal, the heart may not be able to pump the right way. That can result in cardiac arrest. Cardiac arrest is not the same thing as a heart attack.
Sometimes cardiac arrest happens after a heart attack. But it can also happen without one. The brain may also not get enough blood. The lack of blood flow can cause lasting damage to the brain. The person may be unable to regain consciousness. Lowering the body temperature right away after cardiac arrest can reduce damage to the brain.
That raises the chances that the person will recover. Why might I need therapeutic hypothermia after cardiac arrest? Therapeutic hypothermia can help only some people who have had cardiac arrest. Some people regain consciousness right after cardiac arrest. These people often do not need this procedure.
It is helpful only for people whose heartbeat returns after a sudden cardiac arrest. Therapeutic hypothermia can be a good choice if the heart restarted but you are still not responsive. It can raise the chance that you will wake up.
The chemical reactions of the body slow down.
The lowered temperature may also lessen inflammation in the brain. Both of these factors may help reduce injury. What are the risks of therapeutic hypothermia after cardiac arrest?
Therapeutic hypothermia is very helpful for some people. But it has some rare risks.Therapeutic hypothermia after cardiac arrest. N Engl J Med.

Induced hypothermia using large volume, ice-cold intravenous fluid in comatose survivors of out-of-hospital cardiac arrest: a preliminary report. Post-Cardiac Arrest Care/Therapeutic Hypothermia Resources. This site is intended for use by physicians, nurses and other health care providers who are interested in the care of patients after they are resuscitated from cardiac arrest.
Until recently, the outlook for patients who remained comatose after cardiac arrest was dire. But therapeutic hypothermia is turning the . Therapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited.
We conducted this trial of two. Feb 23, · Inducing mild therapeutic hypothermia in selected patients surviving out-of-hospital sudden cardiac arrest can significantly improve rates of long-term neurologically intact survival and may prove to be one of the most important clinical advancements in the science of resuscitation.
