Thirty-eight post-cardiac arrest patients were effectively cooled to the target temperature range of 32-34 celsius using intravenous cold saline and ice packs to groin, axillae, and neck. The ice packs were frozen 250 ml saline bags wrapped in pillow cases. If shivering occurred muscle relaxation with rocuronium was used until the target temperature was reached. Interestingly, rebound hyperthermia occurred in 8/34 patients.
Although a small study, these data reassure those of us who induce therapeutic hypothermia without the use of dedicated cooling equipment.
Cold saline infusion and ice packs alone are effective in inducing and
maintaining therapeutic hypothermia after cardiac arrest
