Frostbite is a cold-induced injury to tissue that requires prompt, structured intervention to limit injury progression and preserve limb function. The first-line approach addresses both immediate tissue protection and the reversal of freezing injury.
The injured extremity presents with cold-damaged tissue following freezing exposure. After any concurrent hypothermia or traumatic emergencies are stabilised, management of the frostbitten area begins immediately. Incorrect handling at this stage can worsen soft tissue injury.
Management centres on careful initial handling of the affected extremity followed by a specific rapid rewarming procedure, with multi-modal analgesia incorporated throughout — the complete step-by-step sequence and all parameters are in the full protocol.
Tissue of the affected extremity becomes red (flushed) or soft and pliable, typically within 20–40 minutes of rewarming.
