autotransfusion
C1/C2Formal/Technical
Definition
Meaning
The reinfusion of a patient's own blood into their body, often during or after surgery.
Any medical or scientific procedure where blood, blood components, or other bodily fluids are collected from an individual and later returned to the same individual's circulatory system.
Linguistics
Semantic Notes
Used almost exclusively in medical, surgical, and emergency contexts. The concept is central to intraoperative blood salvage, trauma care, and some pre-operative donation procedures (e.g., autologous blood donation).
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference; the term is identical. Regional spelling differences do not apply.
Connotations
Neutral technical term in both varieties. Implies medical sophistication and procedures aimed at reducing the need for donor blood.
Frequency
Equally rare and specialized in both dialects, confined to medical professionals and related literature.

Learning
Memory Aids
Mnemonic
AUTO (self) + TRANSFUSION (putting blood in) = putting your OWN blood back in.
Conceptual Metaphor
BLOOD IS A PRECIOUS RESOURCE / RECYCLING (The body's own blood is collected and reused rather than discarded and replaced).

Common Pitfalls
Translation Traps (for Russian speakers)
- Прямой перевод "автотрансфузия" is the correct medical term.
- Do not confuse with "autohemotherapy" (аутосеротерапия), which is a different procedure involving intramuscular injection of one's own blood.
- The word is not related to автомобиль (car) despite the "auto-" prefix.
Common Mistakes
- Misspelling as "auto-transfusion" (hyphen often omitted in modern medical writing).
- Confusing it with "autologous donation," which is collection before surgery, while autotransfusion often refers to intraoperative salvage.
- Using it as a verb (e.g., 'to autotransfuse' is very rare; 'to perform autotransfusion' is standard).

FAQ
Frequently Asked Questions
Yes, in the key aspect of eliminating risks of transfusion-transmitted infections and immunological reactions to donor blood. However, it has its own risks, such as coagulopathy or air embolism if not performed correctly.
No. It is contraindicated in cases where the salvaged blood may be contaminated, such as in surgeries involving infection or cancer, unless special filtering systems are used.
Autologous donation is when a patient donates their own blood for storage weeks before an elective surgery. Autotransfusion typically refers to the immediate intraoperative collection, processing, and reinfusion of blood lost during surgery.
The concept dates back over a century, but modern, effective cell salvage devices for autotransfusion became widely used in the latter part of the 20th century.
