Module 5 Flashcards
(32 cards)
The concentrated, preservative embalming chemical that will be diluted with water to form the arterial solution for injection into the arterial system during vascular embalming.
Arterial fluid
The in-use solution composed of the concentrated embalming fluid diluted with water and other additive (supplemental) chemicals for injection into the body.
Arterial solution
The concentrated embalming chemicals, which are injected into the cavities of the body following aspiration in cavity embalming. This chemical can also be used for surface and hypodermic embalming.
Cavity fluid
Fluid injected for purposes other than preservation and disinfection. Some are injected before the preservative solution; others are injected with the preservative solution (preinjection and coinjection fluids; water corrective fluid)
Supplemental fluid
A group of chemicals used in addition to vascular and cavity embalming fluids; most are applied to the body surface (gels and powders)
Accessory chemical
Fluids designed for use with special body conditions such as jaundice or bodies requiring a high preservative demand as seen in bodies with renal failure, extensive burns, or decomposition
Special purpose fluid
An aqueous solution containing 37% formaldehyde gas by mass in water or in water and methyl alcohol; the most commonly used chemical
Formalin
A polymer of formaldehyde; a white, powdery solid containing from 85-99% formaldehyde. Generally prepared from water solutions of formaldehyde by processes involving evaporation and distillation until concentration to a point at which powdered preparations are involved, such as hardening compounds or other powdered preparations used for “dusting” the body walls and viscera.
Paraformaldehyde
Identifies only the absolute formaldehyde gas present in any given product. Refers only to the amount of formaldehyde gas present.
Index
The methylol derivatives of hydantoin; liberate formaldehyde at a slow rate; low-odor or “fumeless” products; make it possible to formulate fluids tat are pleasant to use
Donor compounds
a stable 2.5% aqueous solution that has a mild odor and a light color; reacts through crosslinking to insolubilize both protein and polyhydroxy compounds; unlike the other aldehydes, it is capable of reacting with protein structures over a wide pH range.
Glutaraldehyde
Also known as carbolic acid, classified as a preservative as well as a germicide; one of the most commonly found components of both arterial and cavity fluids; used chiefly in cavity fluid formulations; coal-tar derivative that is a colorless crystalline solid, upon exposure to strong light, it darkens and assumes an amber or reddish brown appearance when in solution
Phenol
Used chiefly for their germicidal and deodorizing qualities. Use restricted to cavity fluids and specialty formulations used for cold sterilization of instruments, linens, gowns, clothing, and other items; cleaning agents for mold proofing remains and deodorant sprays
Quats
Must be a solvent or mixture of solvents that keeps the active substances in a stable and uniform state during transport through the circulatory system to all parts of the body
Vehicles (Diluents or carrier)
The coloring materials used in modern embalming fluids for the purpose of producing an internal cosmetic effect that closely simulates the natural coloring of tissues.
Dye (Coloring agents)
Control the rate of action of the main preservative chemicals of embalming formulations
Modifying agents
Agents that serve to control the acid-base of fluid and tissues
Buffers
Agents that help to control tissue moisture balance; having a coating action
Humectants
Used to maintain blood in a liquid state and thereby make it easy to remove from the circulatory system
Anticoagulants (water conditioning agents)
Agents that principle is to remove body liquids by lowering their surface tension; one part of molecule has strong attraction or affinity for water, whereas the other dislikes water
Surfactants (wetting agents, surface tension reducers, penetrating agents or surface active agents)
A supplemental fluid that may be injected before the injection of the preservative arterial solution; expands the vascular system, promoting drainage, and prepare the tissues for reception of the preservative arterial solution.
Pre-injection fluids
A supplemental fluid that is mixed and injected along with the arterial solution; designed to enhance the distribution and effectiveness of the arterial solution
Co-injection fluids
Added and injected along with arterial fluid; used when the body is dehydrated or to prevent dehydration
Restorative fluids (Humectant)
Reduce tissues swollen with edema; added to the preservative arterial solution as a coinjection fluid; changes the osmotic qualities of the embalming solution and draws the edema from the tissue spaces back into the venous drainage
Edema fluid
