Something Important Is No Longer Attached
Traumatic amputation protocol, life-over-limb bleeding control, and proper dry-cold amputate preservation
// IMMEDIATE ACTIONS
Execute these steps in order:
- 01 CONTROL LIFE-THREATENING BLEEDING FIRST
Apply direct pressure, pack wound, or place a windlass tourniquet 5–7 cm proximal on the stump.
- 02 CALL 911 / 112 IMMEDIATELY
Notify dispatch of traumatic amputation so a specialized replantation center can be prepared.
- 03 PACKAGE AMPUTATED PART (3-LAYER RULE)
Preserve tissue viability without causing irreversible frostbite necrosis:
- ├─ Layer 1: Wrap severed part in clean, dry sterile gauze (never soak in water).
- ├─ Layer 2: Place wrapped part into a watertight sealed plastic bag.
- └─ Layer 3: Place sealed bag into an outer container with an ice-water slurry at ~4°C (never put part directly on ice).
// CRITICAL MISTAKES (DO NOT)
- ✕ Never place the amputated part directly in contact with ice or dry iceWHY: tissue freezing destroys microscopic blood vessels
- ✕ Never submerge the unprotected amputated part directly into water, saline, or alcoholWHY: causes severe cellular swelling and tissue maceration
- ✕ Never scrub, scrape, or disinfect the severed tissue with harsh chemicalsWHY: wipes out viable endothelial cells
- ✕ Never delay emergency transport of the hemorrhaging patient to search for small severed fragments in tall grass or machinery.
“Stop catastrophic bleeding first with a tourniquet/pressure, wrap the amputated part dry, seal it in a bag, and place the bag in ice water.”
A high-energy industrial saw blade, agricultural machinery, severe crush injury, or vehicular collision can result in a traumatic amputation—the complete severance of a finger, hand, foot, or entire limb.
In traumatic amputation, two distinct medical missions occur simultaneously:
- The Primary Mission: Preventing the patient from bleeding to death from severed major vessels within 180 seconds.
- The Secondary Mission: Preserving the severed tissue in a viable state for microvascular replantation surgery within the warm/cold ischemia window.
The Doctrine: Life Over Limb
The most common mistake by untrained bystanders is immediately panicking about finding and saving the severed limb while the patient silently exsanguinates onto the floor.
- Arterial Hemorrhage: Severed radial, brachial, or femoral arteries can pump out 500 mL of blood every 15 to 30 seconds.
- Tourniquet Application: If direct manual pressure with a bulky sterile dressing does not instantly halt bleeding, apply a commercial windlass tourniquet (e.g., CAT or SAM-XT) 5 to 7 cm (2 to 3 inches) above the injury. Tighten until bleeding stops completely and record the time of application on the patient’s forehead.
The Amputate Preservation Protocol: The 3-Layer System
To successfully reattach a severed body part, microvascular surgeons must sew together microscopic arteries and veins measuring under 1 to 2 millimeters in diameter under high-power surgical microscopes.
If the amputated part is mishandled, replantation becomes biologically impossible:
- Layer 1 (The Sterile Wrap): Wrap the severed part in clean, sterile, dry gauze (or very lightly moistened with saline). Never scrub the severed margins.
- Layer 2 (The Watertight Seal): Place the wrapped part inside a clean, waterproof plastic bag (such as a Ziploc bag) and seal it tightly.
- Layer 3 (The Ice-Water Slurry): Place the sealed bag into a second container filled with a mixture of ice and cold water.
- The water acts as a thermal buffer, keeping the tissue at an optimal +4°C (39°F).
- Why Raw Ice is Lethal: Direct contact with ice or dry ice causes intracellular water to form sharp ice crystals that puncture cell membranes, causing full-thickness frostbite necrosis. A frozen digit cannot be reattached.
- Why Submerging in Water is Lethal: Soaking the raw tissue directly in water causes hypotonic osmotic swelling, dissolving cellular architecture (maceration).
112 reaches fire and emergency medical dispatch directly. 110 is police.
