Abstract

To evaluate the effects on temperature and outcome at hospital discharge of a pre-hospital rapid infusion of large volume, ice-cold intravenous Hartmann?s solution in patients with out-of-hospital cardiac arrest and an initial cardiac rhythm of asystole or pulseless electrical activity. Design: Prospective, randomized, controlled clinical trial. Setting: Pre-hospital emergency medical service and 12 critical care units in Melbourne, Australia. Patients: One hundred and sixty three patients who had been resuscitated from cardiac arrest with an initial cardiac rhythm of asystole or pulseless electrical activity. Interventions: Patients were randomized to either pre-hospital cooling using a rapid infusion of up to two litres ice-cold Hartmann?s solution (82 patients) or cooling after hospital admission (81 patients). The planned duration of therapeutic hypothermia (32?C?34?C) in both groups was 24 hrs. Measurements and Main Results: Patients allocated to prehospital cooling received a median of 1500 ml of ice-cold fluid. This resulted in a mean decrease in core temperature of 1.4?C compared with 0.2?C in hospital cooled patients (p <.001). The time to therapeutic hypothermia (
