Escape of blood serum from an intravascular to an extravascular location immediately before death is an example of which antemortem change?

• A. agonal edema
• B. agonal dehydration
• C. moisture antemortem change
• D. bacterial translocation

Answer: (A)

In the dying process, changes occurring just before death are called agonal changes. One common finding is edema that develops as fluids shift from the intravascular space into the interstitial (extravascular) tissues due to worsening circulation and venous congestion. This leakage of serum into tissues right before death fits the description of agonal edema, making it the best choice.

The other options don’t fit because they describe fluid loss (agone dehydration), an unfamiliar or incorrect term (moisture antemortem change), or a gut-related microbial event (bacterial translocation) that isn’t about serum escaping into tissues during the agonal period.
