Be conservative in the administration of potassium while the patient is still hypothermic (this may promote rebound hyperkalemia). Patients with prolonged cardiac arrest may eventually develop hyperkalemia.What are the treatment options for hypothermia in patients on ECMO?
Extended CPR should be performed (hypothermic patients can have excellent outcomes despite hours of CPR). Patients can even do OK despite brief pauses in CPR, because hypothermia protects the brain from injury. Transport to an ECMO center may be beneficial, even if it's not the closest hospital.How is hypothermia diagnosed in a patient with unexplained hypothermia?
Unexplained hypothermia often signals severe illness: this should be a trigger to provide aggressive and thoughtful resuscitation. Most standard thermometers don't read below 34C, so these may fail to detect severe hypothermia. If the patient feels cold but the thermometer isn't reading low, obtain a core temperature as described above.
