The protocols at my new agency (Department of Defense) allows drill sergeants, and other cadre to dunk the patient in an ice water lavage. A core temp is required before doing so. EMS will continue constant core temp monitoring, administer 36 degree IV saline along with either Hypertonic saline or sodium bicarbonate depending on our iSTAT results at point of contact. Enroute to the ER we will dump water on the patient to promote active cooling. Depending on initial core temp will determine our transport priority, and interventions at the ER.
