How should an EMT properly handle an amputated thumb retrieved from an accident?

When handling an amputated body part, such as a thumb, the priority is to preserve the tissue for potential reattachment. Wrapping it in a dry sterile dressing is the appropriate method because it helps protect the tissue from contamination and further damage while maintaining a suitable environment for tissue survival.

Using a dry sterile dressing prevents moisture accumulation and reduces the risk of infection. It also provides a layer of protection during transport. While the tissue should be kept cool to preserve viability, direct contact with ice can cause frostbite and additional harm, making it unsuitable as a method for preservation.

Submerging the amputated part in saline solution may seem reasonable, but it can lead to tissue damage and is not recommended. Reattaching the thumb would only be performed in a surgical setting by trained professionals, and is not an action that EMTs carry out at the scene. Hence, wrapping the severed thumb in a dry sterile dressing is both practical and aligns with best practices for first responders.
