<prompt> Hypothermia is used in all except:Neonatal asphyxiaCardiac surgeryHyperthermiaArrythmia  <response>: There is substantial protection against ischemia and hypoxia is provided by. just 1-3C hypothermia. Hypothermia reduces the tissue metabolic rate about 8OC. 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 30C, spontaneous ventricular fibrillation may be seen but is not likely above 28C. So hypothermia is arrhythmogenic
