Embalming Flashcards

Edematous cases present excess interstitial fluid. The embalmer should:

Answer: Use a high-index, low-humectant fluid and restrict drainage

High-index fluid provides stronger preservation, and limiting humectant reduces additional moisture retention in already waterlogged tissue.

Which of the following best describes secondary dilution in embalming?

Answer: Dilution of arterial fluid by interstitial fluids already in the body

Secondary dilution occurs when body fluids mix with and weaken the injected arterial solution within tissues.

The femoral artery is commonly selected for injection when:

Answer: The face must remain undisturbed for viewing or autopsy restrictions

Using the femoral artery keeps the incision away from the visible neck area, preserving a clean presentation.

What does a 'high index' arterial fluid mean?

Answer: It has a higher percentage of formaldehyde by volume

The index number indicates the percentage of formaldehyde in the concentrate; higher index equals stronger preservative action.

Jaundice in a decedent causes embalming challenges primarily because:

Answer: Bilirubin discolors tissue and may react with formaldehyde to deepen the yellow color

Formaldehyde can intensify jaundiced discoloration, so embalmers must use special bleaching or co-injection chemicals.

Which structure is ligated during embalming to control drainage?

Answer: The jugular vein

The internal or external jugular vein is often ligated after drainage is complete to prevent leakage.

Cavity fluid is typically much higher in formaldehyde index than arterial fluid because:

Answer: Organs are dense and poorly perfused, requiring stronger preservation

Solid organs resist chemical penetration, so concentrated cavity fluid is needed to achieve adequate preservation.
