The process of executing therapeutic hypothermia on patients involves the use of a catheter, which is placed in the inferior vena cava through the femoral veins in the legs through a method known as invasive therapeutic hypothermia. Non-invasive therapeutic hypothermia involves an external application of a blanket that is made extremely cold by water. Strict adherence to the therapeutic hypothermia has been proved to reduce the level of risks for ischemic brain injuries that patients under such conditions of insufficient blood supply are exposed to. The development of therapeutic hypothermia to help reduce the levels of risks that patients recovering from cardiac arrest are exposed was developed by Greek physician Hippocrates when he advocated for the packing of wound soldiers in snow ice, a form of non-invasive therapeutic hypothermia. Studies into the application of therapeutic hypothermia in modern medicine began in 1945 when the first publication on the topic was made as documented by Storm, Steffen and Schefold, (2008). This paper will evaluate how induced therapeutic hypothermia affects the neurological functions and help post cardiac arrest patients recover. The impacts of the practice in reducing the development ischemic injury in cardiac arrest patients will also be evaluated. Literature review The aftermaths of cardiac arrest involves neurological injuries, which results into impairment of oxygen flow into the brain, causes anaerobic metabolism in the brain. As stated by Riana, Abella and Mary, (2006), anaerobic metabolism disrupts adenosine triphosphate dependent cellular pumps, which lead to generation of excess calcium and glutamate in the excretions. This results into excitation of the brain, which magnifies hypoxemia resulting into mitochondrial and cellular death. Disruption of blood brain barrier results into initial injury resulting into increased fluid flow into the brain resulting into worsens state of cerebral edema. This is exactly how persistent cardiac arrest result into increased level of neurological defects, a condition that can be arrested using therapeutic hypothermia. The application of therapeutic hypothermia results into counteractions of the neuroexcitations in the brain cells through process that stabilize the calcium and glutamate release resulting into decreased apoptosis in the brain. It also acts to stabilize the blood brain barrier resulting into reduced flow of fluids into the brain tissues thus reducing the instances of developing cerebral edema. Therapeutic hypothermia thus reduces the destructive mechanisms of cardiac arrest thus reducing the damaging impacts it may produce to the brain and the central nervous system according to Tsai, Barbut and Wang, (2008a). Based on Matthias, Fries and Rossaint (2012), therapeutic hypothermia is done following a three phase procedure, which includes induction, maintenance and re-warming which must be done under controlled environments to prevent potential adverse effects of the procedure. The induction phase enables the attainment of a patient’s target body temperature within the shortest time possible. This is done using solid ice packs, ice lavage or even ...Download file to see next pagesRead More

CARDIAC ARREST

...disease occurs to people who suffer from coronary heart problems. These peoples have clogged blood vessels which can create problem for normal heart functioning. Heart attack: If a person encounters with heart attack due to the vermicular fibrillation, the result can be sudden cardiac arrest. Moreover, heart attract creates scars in heart tissue which lead to electrical short circuits interfering with it and causing cardiac arrest. Cardiomyopathy(Enlarged Heart):Once the muscular walls of heart get thickened the result can be cardiac arrest. Since this process makes heart muscles abnormal, the outcome...

...The use of therapeutic hypothermia to improve the neurological outcome after cardiac arrest This paper heralds a future research study into investigating whether therapeutic hypothermia initiated by infusion of cold () normal saline (2L) will be sufficient in producing better neurologic outcomes in patients of out-of-hospital cardiac arrest. The paper has proposed three hypotheses the proving correct of which shall entail success. The main significance of the study is to correctly ascertain the optimal duration of hypothermia, the optimal target temperature and the rates of cooling and rewarming. Its importance lies in the fact that many patients of cardiac arrest experience global ischemia that inflicts often irreparable damage... to...

...). Studies have shown that cardiac arrest due to ventricular fibrillation (VF) has improvedneurological outcome with the use of induced mild therapeutic hypothermia. Asystole or pulseless electrical activity, a dire form of cardiac arrest in which the heart stops beating, has not been sufficiently studied to recommend the routine use of hypothermic modulation of anoxic brain injury (Green, 2005). Until recently, prognosis of patients with asystolic out-of-hospital cardiac arrest have not been...

...blockers (Svensson et al. 1986). Conclusion In view of the problem, doctors that insist on starting the active cooling are in line with protocol guidelines. As a support for the previous discussion, increased brain temperature contributes to ischemic brain damage in patients post cardiac arrest. Much of the studies have shown that induced hypothermia or lowering brain temperature for even a few degrees will decrease ischemic damage and have contributed in the improvement of neurological outcomes. This factual and proven statement is enough to support induced...

...hypothermia has been credited to the great enhancement of survival rates from such sudden cardiac arrests with a huge influence on the long-term neurologically intact survival too. Further research and animal tests also point, importantly, that the earlier the hypothermia is induced, the better and higher the patient’s outcome and survival rates (Bader, 2011).

The credibility of their work is in the fact that it does not only emphasise short term results but focuses directly on long term outcomes taken as a result of follow up of subjects. This source was included as a quality source of information on how post-resuscitation life was going to be for Mr. B. This was particularly necessary as the patient was noted to have started showing signs of improvement shortly after treatment. Hachimi-Idrissi S, Corne L, Ebinger...
