Hypothermia is used in all except:

There is substantial protection against ischemia and hypoxia is provided by. just 1-3°C hypothermia. Hypothermia reduces the tissue metabolic rate about 8%/OC.   It decreases the cerebral metabolic rate and is cerebroprotective during episode of cerebral ischemia The protection afforded by mild hypothermia is so great that reduced core temperature 34° probably indicated in   - Carotid artery surgery - Neurosurgery   - Procedures where tissue ischemia can be anticipated   - Traumatic brain injury - ARDS   - Malignant hyperthermia .   Hypothermia is used in cardiac surgery as cooling does slow heart and greatly depresses body metabolism .   Dysrhythmia occurs at temperature below 30°C, spontaneous ventricular fibrillation may be seen but is not likely above 28°C. So hypothermia is arrhythmogenic
