Embalming fluid

Quaternary Ammnonium Compounds

used chiefly for their germacidal and deodorizing qualities, use is restricted to cavity fluids and specialty formulations used for cold sterilization of instruments, linens, gowns, clothing. Also used as cleaning agents for mold proofing remaisn and deodorant sprays.

Arterial embalming

the use of the blood vascular system of the body for temporary preservation, disinfection and restoration; accomplished through injection of embalming solutions into the arteries and drainage from the veins

Arterial fluid

concentrated preservativve embalming chemical for injection into the arterial system during vascular embalming

Arterial solution

mixture of arterial fluid and water used for arterial injection and may include supplemental fluids

Cavity fluid

concentrated embalming chemical injected into the cavities of the body following the aspiration of the body; can also be used in hypodermic and surface embalming

Supplemental fluid

fluid injected for purposes other than preservation and disinfection

Accesory chemical

a group of chemicals used in addition to vascualr and cavity embalming fluids; most are applied to the body surface

Special purpose fluids

fluids designed for use with special body conditions such as jaundice or bodies requiring with a high preservative demand as seen in bodies with renal failure, extensive burns or decomposition

Minimum solution strength

2%

Preservative

react with proteins to fixate

Aldehydes

react with various forms of nitrogen found in proteins

Formalin

commerical source of formaldehyde

Discovered formaldehyde

Alexander Butlerov

Identified a way to make formaldehyde

Wilhelm VonHofmann

Paraformaldehyde

a polymer of formaldehyde, white powdery substance, contaisne 85% to 99% of formaldehyde

Glutaraldehyde

reacts with protein at higher pHs that would essentiallt render formaldehyde inactive

Phenol (carbolic acid

perservative as well as a germicide, most used arterial and cavity fluid in early industry

Germicide

sanitizes tissues of the body

Quaternary Ammonium Compounds

used for its germicidal and deodorizing qualities

Modifying agents

Controls the rate of action of the main preservative chemicals in embalming formulations

Buffers

Agents that serve to control the acid-base balance of fluid and tissues

Humectants

agents that help control tissue moisture balance

Anticoagulants

water conditioning agents

Surfactants

wetting agents, surface tension reducers, penetrating agents or surface-active agents

Borates

reduces the harding and graying actions of formaldehyde, stabilizes foramlin

Carbonates

used in combination with borates to modify the action of formaldehyde

Glycerin

an alcohol, not a germicide or a preservative, increases germ killing power of other chemicals, good lubricator and hygroscopic, helps to prevent dehydration

Sorbitol

used more than glycerin since it loses water slower, used to mitigate drying chemicals

Perfuming materials

by blending special synthetic essential oils with a harsh preservative chemicals in a formulation, the harshness or "raw" odor of the solution is reduced and replaced to some extent by a more pleasing scent

Vehicle

liquid that serves as a solvent for embalming fluids.

Preservative arterial fluids dilution

diluted with water and supplemental arterial chemicals

cavity fluids dilution

undiluted

Stong formaldehyde index

26-36

Medium formaldehyde index

16-25

Low formaldehyde index

5-15

Non cosmetic

fluids that containe little or no active dye and do not color tissue

Cosmetic

FLuids that contain an active dy that colors the tissues

Fast-firming

fluids buffered to firm tissues rapidly

Slow-firming

fluids buffered to firm body tissues slowly

Soft firmness chemical

Fluids buffered and contain chemicals to control the preservative reaction to produce very little firming of the tissues

Mild firmness chemical

Fluids buffered and contain chemicals to control the preservative reaction to produce a medium firming of the tissues

Hard firmness chemical

Fluids buffered and contain chemicals to control the preservative reaction to produce very definite and hard firming tissues

Humectant chemical

fluids that contain large amounts of chemicasl that add and retain tissue moisture

Non-humectant chemical

fluids that do not contain chemicals that add or retain moisture

Jaundice fluids

fluids compounded to cover or remove the dicoloration of berillium

Tissue gas fluids

fluids designed to arrest and control the causative agent Clostridium perfringens

pre-injection fluid

supplemental fluid that may be injected before the injection of preservative arterial solution

Co-injection Fluid

primarly used to supplemtn and enhance the action of vascualr solutions

water corrective fluid
