This method is inexpensive and represents an appropriate way to initiate cooling. However, it can be messy and is less than optimal in the rate of cooling and target temperature maintenance. Practically, ice packs are placed in anatomic areas that have large heat-exchange capability (the head, neck, axillae, and groin) and are replaced when the ice packs have substantially melted. In addition to ice packs, evaporative cooling with fans has been used. The average temperature drop using ice packs is moderately slow and highly variable and is reported to be 0.03ºC-0.98°C per hour.
