Deep hypothermic circulatory arrest

Used in cardiac, thoracic, and neurosurgical procedures requiring bloodless field Reduces core temperature for neuroprotection during global ischemia Temperature target: 15-22°C (59-71.6°F) Must continue cardiopulmonary bypass 20-30 minutes after reaching target temperature to ensure proper brain cooling Operative time goal: 45-60 minutes or less Brain temp: No reliable direct method to measure brain parenchymal temperature Jugular bulb temperature is "gold standard" but still not direct correlation Full-flow cardiopulmonary bypass used to achieve cooling: continue CPB for 20-30 min after reaching the target temp Can verify isoelectricity with BIS or EEG Side Effects: Coagulopathy Increased blood viscosity Enhanced systemic inflammatory response Increased organ damage risk
