A digital amputation, or the complete severing of a finger, is a severe, time-sensitive injury requiring immediate action. The potential for successful reattachment, known as replantation, is directly linked to the speed and quality of the initial first aid provided to both the injured person and the severed part. Preserving the viability of delicate tissue, such as nerves and blood vessels, until specialized medical treatment can be administered is crucial. Understanding the correct steps for stabilization and preservation can significantly improve the outcome and function of the replanted digit.
Immediate Care for the Injured Person
The primary focus immediately following a traumatic amputation must be on stabilizing the injured person and controlling blood loss from the stump. Hemorrhage control is the most immediate life threat, requiring direct, firm pressure to the wound site. A clean cloth or sterile dressing should be placed directly over the injured area and pressed down steadily.
If the initial dressing becomes saturated, apply a new dressing directly over the top of the first one; removing saturated material can disrupt the forming clot and restart bleeding. Wherever possible, elevate the injured hand above the level of the heart to help reduce blood flow and minimize swelling. Avoid using a tourniquet unless the blood loss is catastrophic and life-threatening, as improper use can cause extensive damage.
Monitor the person for signs of shock, such as paleness, rapid pulse, or lightheadedness due to blood loss and trauma. Keeping the injured individual calm, warm, and lying down can help mitigate the effects of shock until emergency medical services arrive.
Preserving the Severed Digit
The proper handling of the severed digit is crucial for determining the success of replantation surgery. The goal of preservation is to cool the tissue to slow its metabolic rate and degradation without causing freezing damage. Begin by gently rinsing the amputated part with clean water or a sterile saline solution to remove contamination or debris; scrubbing must be avoided as it can damage the tissue.
The rinsed finger should then be wrapped in a slightly dampened sterile gauze or a clean cloth. This wrapped digit must be placed into a clean, sealed, watertight container or plastic bag. This protects the digit from contamination and prevents direct contact with the cooling medium.
This sealed bag is then placed into a second, larger container filled with a mixture of ice and water, often called an ice slush. This method maintains a cool, consistent temperature, ideally around 4°C (39°F), which extends the tissue’s viability for many hours. Never place the severed digit directly onto dry ice or pure ice, as the extreme cold causes frostbite and irreversible tissue damage, rendering the digit unusable for replantation.
Urgent Medical Transport and Communication
Time is a fundamental factor in replantation success, with the window for viable reattachment typically lasting up to 12 hours for a clean amputation. The immediate step is to contact emergency medical services by calling 911 (or the local emergency number) to arrange rapid transport. The most appropriate destination is a hospital with specialized microsurgery capabilities, such as a Level I trauma center or a dedicated hand surgery center.
When communicating with emergency responders or hospital staff, several pieces of information are useful for the medical team. Crucially, the time of the injury must be stated clearly, as this establishes the total ischemic time for the digit. Details regarding the mechanism of injury, such as a sharp cut versus a crush or avulsion injury, help surgeons anticipate the extent of tissue damage.
Confirming that the severed digit is recovered, properly packaged, and traveling with the injured person ensures the surgical team can begin preparations immediately upon arrival.
