Current cooling method for Exert ional Heatstroke at the US Marine Corps
Training Base at Parris Island:
a) An ice chest is constantly available during physical training. Dedicated tubs of water
and ice are standing by.
b) In the field, the blouse and pants are removed from a patient who has collapsed from
suspected heatstroke; shorts and T-shirt are left on. Rectal temperature is measured;
if > 39.4C, the patient is wet down, ice is packed around the groin and axillary areas,
the patient is immediately transported to the clinic on a stretcher. Upon arrival, the
stretcher is placed on top of the iced bathtub above the water and ice, with the
carrying handles sticking out at both ends.
c) Mental status and other vital signs re assessed and blood is drawn for lab analyses.
d) 1 liter of NS is administered as a bolus.
e) Sheets are dipped into the tub's icy water and are used to cover and drench the
patient. Copious ice is added to the top of the sheet to cool the patient further, and
