Comparative Study
Application of normothermic cardiac arrest algorithms to hypothermic cardiac arrest in a canine model.
International guidelines (2000) do not recommend vasopressor and antiarrhythmic medications during ventricular fibrillation (VF) with a core temperature below 30 degrees C. The efficacy of normothermic AHA algorithms using standard doses of epinephrine (EPI) (adrenaline) followed by amiodarone (AMIO) in hypothermic VF is uncertain. ⋯ In this model of severe hypothermia, the use of standard 2000 protocols for VF resulted in a significant increase of CPP, and, a higher ROSC rate compared to placebo controls. This study suggests that AHA normothermic algorithms may be beneficial in severe hypothermia.
