<prompt> Hypothermia is used in all except :Neonatal asphyxiaCardiac surgeryHypehermiaArrythmia  <response>: D i.e. Arrythmia Hypothermia Hypothermia provides protection against ischemia hypoxiaQ by reducing metabolic rate about 8 degC2 It decreases the cerebral metabolic rate is cerebro-protective during episodes of cerebral ischemia 1-3degC hypothermia core temperature 34degC is indicated in NeurosurgeryQ Carotid aery surgery Cardiac surgeryQ Traumatic brain injury ARDSQ Malignant hypehermiaQ Procedure where tissue ischemia is anticipated Prolonged surgeriesQ Dysarrhythmia occurs at temperature below 30degC, spontaneous ventricular fibrillation may be seen but is not likely above 20degC. As hypothermia is arrythmogenic so hypothermia is C1 in arrythmiaQ
