Recognizing Early Signs of Hypothermia in the Field?

Recognizing Early Signs

In the field, recognize early signs of hypothermia by monitoring for changes in behavior, motor skills, and mental status. Shivering is an early indicator of hypothermia, but it can be masked by fatigue, pain, or cold shock. Observe for confusion, disorientation, and slurred speech, which may be early signs of hypothermia affecting the brain. Monitor for changes in skin color, which may change from pink to pale or blue.

Rewarming Techniques

When treating hypothermia in the field, use passive rewarming techniques initially. Move the patient to a warm, sheltered location, and remove any wet clothing. Apply a warm, dry blanket, but avoid direct heat sources, such as hot water bottles or fires, as they can cause burns. For more severe cases, use active rewarming techniques, such as warm IV fluids or a warming blanket, but be cautious of afterdrop, a drop in body temperature after rewarming begins.

Severe Cases and Afterdrop

Be aware of severe cases of hypothermia, where the body temperature drops below 90°F (32°C). In such cases, seek medical attention immediately, as rewarming may be required in a medical facility. Monitor for afterdrop, which occurs when the body temperature drops rapidly after rewarming has begun. To prevent afterdrop, rewarm slowly, using a gradual increase in temperature, and avoid rapid changes in body temperature.
