- Multiple factors affect if a digit can be reattached including: location of digit injury, mechanism of injury, duration since injury, preservation mechanism.
- Recommended preservation is via indirect cooling. This is accomplished by wrapping the amputated digit piece in saline soaked gauze, placing the wrapped piece in a waterproof bag and putting the bag in ice water for transport. Avoid direct contact of the digit with ice.
- A single center study showed that only 34% of the total digits received were properly preserved. Lower rates of indirect cooling were seen in patients arriving from home or via EMS (25% and 35% respectively). Of those transported from referring hospitals, still only 45% of digits were properly preserved. Therefore, consider providing preservation instructions for indirect cooling to those transporting amputated digits.
