index
the number of grams of formaldehyde gas dissolved in 100 ml of water; usually given in a percentage
index
having an index of 28 - 36. Causes a rapid tissue coagulation.Causes a definite degree of firmness, used most often on “special cases.” (Decomposition, edema, outgoing, drowning, etc.)

What are the components of vascular (arterial) fluids?
preservativesupplementary germicideanticoagulantsvehicleperfuming agents, deodorants, or masking agentsdyessurfactantsmodifying agents
Chemical which inactivates saprophytic bacteria, render unsuitable for nutrition the media upon which bacteria thrive, and which will arrest decomposition by altering enzymes of the body as well as converting the decomposable tissue to a form less susceptible to decomposition. One of the components of arterial fluids
preservative
actions of preservative chemicals
- Inactivates the chemical group of proteins or amino acids2. Inhibits further decomposition3. Inactivates some enzymes4. Kills some microorganisms – not all5. Destroys odors
examples of preservatives
aldehydesalcoholphenol
an example of a preservative: deprived of hydration, its common name is formaldehyde
aldehydes
produced by the partial oxidation of methanol
formaldehyde
in its free state, formaldehyde is a _______, it is __________ in water which forms a ________. __________ is the universal solvent. Every solvent has a different ___________ rate
gassolubleformulawatersaturation
Characteristic of formaldehyde
Colorless gas Has an irritating and unpleasant odor – pungent Freely soluble in water Combines with tissue protein Is a monoaldehyde (one functional aldehyde group)
classified as a dialdehyde (Two functional aldehyde groups) Five carbons rather than one
Gluteraldehyde
2 types of alcohols (also examples of preservatives)
Methyalcohol (methanol or wood alcohol) Ethyalcohol (ethanol or grain alcohol)
an alcohol that has two primary uses - used commercially to manufacture formaldehyde- is also an antipolymerizing agent (ensures it stays in its liquid state)
Methyalcohol (methanol or wood alcohol)
an example of a preservative: obtained by the distillation of coal tar.- Used as cauterizer to prevent leakage on embalmed bodies- Also, a bleaching agent - inject it do not use as a surface application
phenol
One of the components of arterial fluids. Chemicals added for the purpose of destroying disease causing microorganisms
Supplementary GERMICIDES
Examples of supplementary germicides
Glutaraldehyde Quaternary ammonium compounds –
better disinfectant used as a supplementary germicide
Glutaraldehyde
agents that are usually used for disinfection of skin, oral, nasal cavities, and instruments. EXAMPLES: Benzalkonium and Zephrian
Quaternary ammonium compounds –
Chemicals which retard the tendency of blood to become more viscous (thicker) by natural postmortem processes or prevent adverse reactions between blood and other embalming chemicals. This process is primarily accomplished by breaking down the calcium in the blood and water. One of the components of arterial fluids.- Also known as water conditioners or water softeners.- These chemicals help keep blood in a liquid state
ANTICOAGULANTS
Examples of anticoagulants:
Sodium citrate– .Sodium salt of EDTA = (Ethylenediaminetetrasodiumacetate) –
an example of an anticoagulant: white, odorless, crystalline or granular material is often used for its anticoagulation. This compound inactivates calcium in the blood as well as in the water supply. W/O calcium, blood coagulation does not occur
Sodium citrate
an example of an anticoagulant: very effective sequestering or chelating agents, means – they are readily combined with calcium ions to prevent blood coagulation and also to remove hardness chemicals from the water supply.
Sodium salt of EDTA
One of the components of arterial fluids. Liquids that serve as a solvent for the numerous ingredients that are incorporated into embalming fluids. They must serve as the carrier of the components found in the arterial solution. Alcohols
vehicle
most common vehicle
water
will also serve as a vehicle. (Tincture solution). Its most common use of as a vehicle would be cavity fluid
alcohol
One of the components of arterial fluids. Chemicals having the capability of displacing an unpleasant odor or of altering an unpleasant odor so that it is converted to a more pleasant odor.Odorless or fume less chemicals
PERFUMING AGENTS, DEODRANTS OR MASKING AGENTS
Examples of perfuming agents (4)
Methylsalicylate (oil of wintergreen) Benzaldehyde (oil of almonds) Oil of sassafras Oil of cloves
do not eliminate the effects that formaldehyde has on the operator.
Perfuming agents
One of the components of arterial fluids Substances which will, upon being dissolved, impart a definite color to the embalming solution and/or tissues.
DYES (coloring agents)
dye that will impart a color to the body tissue
Cosmetic dyes (active)
dye that will stain the concentrated arterial fluid.

When selecting arteries,the considerations and precautions based upon:
- Accessibility 2. Arterial occlusion- hardening of the arteries
when considering if an artery is accessible what should be some of the determining factors?
Superficial or deepSurrounding structuresSize (diameter)Proximity to aortaAccessibility for drainage from corresponding vein
Factors governing selection of arteries for injection (9)
- Age: Infant (descending abdominal aorta) or Adult2. Weight (corpulence)3. Disfiguration - scar tissue, arthritis, etc.4. Disease - cancer, goes hand in hand with disfiguration, etc.5. Edema - excessive fluids6. Obstruction - vascular or extravascular7. Trauma - any type of wound or injury8. Medico - legal requirements9. Cause and manner of death
Proper technique for raising vessels
- Shave area if necessary2. Select instruments and prepare ligature or necessary instruments.3. Locate place of incision using linear guide.4. Make incision through skin, superficial fascia and deep fascia.5. Use blunt dissection through superficial fascia and deep fascia, and adipose tissue.6. Locate vessels by use of anatomical guide.7. Clean vessels by blunt dissection and ligate vessels.8. Make incision in vessel.
the most common incision method employed to open the artery or vein. Cut is made from the edge of the vessel to the center of the vessel
Transverse incision
an incision made involving cutting at an angle
Diagonal incision
this incision is made when embalmer likes to use drain tube in neck
“T” incision
this incision is used on a sclerotic artery, because it does the least amount of damage to the walls of this vessel that are already diseased
Wedge incision
most popular and common stitch. Y
Baseball
the least leak proof of any suture, they form the least prominent ridge. The most common use is on parts of the body that will be seen in an open casket. This is a hidden stitch, within the skin - used on the face.
Intradermal
other types of incisions
Whip or roll stitch – illustrated in text bookDraw stitch
Other methods of closing the incision:
AdhesivesSurgical staples
4 types of injections discussed:
One point injection Split injection/drainage Multi-point injection Restricted cervical
type of injection where one location is used for both injection and drainage.
One point injection
most common sites for one point injections
Common carotid artery/ internal jugular vein Femoral artery and vein
Injection from one location and drainage from a separate location.
Split injection/drainage
Most common site for split injection/drainage
Injection - right femoral arteryDrainage - right internal jugular vein
Inject from two or more arteries This procedure ensures better distribution throughout the body.
Multi-point injection
Both common carotid arteries are raised. Allows the head to be injected separately.
Restricted cervical
Used if the embalmer is concerned about distention or swelling of the facial features during the embalming process (car accident, head trauma), or if there is a major restorative art project
Restricted cervical
