Which guideline should you follow in managing patients with a local cold injury?

In managing patients with a local cold injury, it is critical to avoid applying direct heat, such as hot packs, to the affected area. This approach is correct because direct heat can cause further tissue damage. The affected tissues are often sensitized due to the cold injury, making them more susceptible to burns and further trauma when exposed to high temperatures.

Instead, rewarming should be done gradually and in a controlled manner. This helps to prevent reperfusion injury, which can occur if cold tissues are exposed to sudden temperature changes. Utilizing warmer temperatures surrounding the affected area, rather than direct heat, allows for a safer, more effective rewarming process that closely monitors the patient's response to the treatment.

By prioritizing gradual rewarming and avoiding direct heat, EMTs can effectively reduce the risk of further complications from the cold injury and promote better outcomes for the patient.
