Embalming Techniques & Protocols Flashcards

Which embalming technique is most appropriate when arterial embalming alone fails to adequately preserve the abdominal region?

Answer: Perform cavity embalming using a trocar

Cavity embalming with a trocar allows direct aspiration of gases and fluids and injection of cavity fluid into the thoracic and abdominal cavities when arterial distribution is insufficient.

What is the primary purpose of using a humectant in embalming fluid formulations?

Answer: To retain moisture and prevent excessive tissue dehydration

Humectants such as glycerin draw and retain moisture within tissues, helping to prevent the over-dehydration that can cause skin to appear sunken or leathery.

When embalming a body with advanced decomposition, which adjustment to the embalming solution is most critical?

Answer: Increase the index strength and use co-injection fluids

Advanced decomposition requires a higher preservative index and co-injection fluids (such as water conditioners and humectants) to counteract tissue breakdown and purge conditions.

The 'six-point injection' method refers to embalming using which combination of vessels?

Answer: Right and left common carotids, right and left femorals, and right and left axillaries

The six-point injection uses bilateral common carotid, femoral, and axillary arteries to ensure thorough distribution when a single-point injection is inadequate.

What condition is indicated when embalming fluid appears at the incision site without adequate tissue firming?

Answer: Short-circuit or channeling of fluid through a path of least resistance

Short-circuiting occurs when fluid travels rapidly through dilated or damaged vessels and exits before achieving adequate preservation in surrounding tissue.

Which post-embalming technique is used to reduce jaundice discoloration in surface tissues?

Answer: Use a bleaching or jaundice-correcting embalming fluid co-injection

Jaundice corrector co-injection fluids contain compounds (often containing oxalic acid derivatives) that chemically reduce bilirubin staining in tissues during arterial injection.

Which anatomical site is typically raised for arterial injection in a standard embalming procedure on an unembalmed adult?

Answer: Right common carotid artery

The right common carotid artery is the most commonly raised vessel in standard embalming because it provides excellent distribution to the head and, via the arterial network, to most of the body.
