quiz 7 Flashcards
active dyes
- Act as a tracer to see distribution of arterial fluid
- Help restore natural color
- Help prevent body from darkening as results of reaction with the blood remaining in body after embalming
anticoagulants
- water conditioning agents
- used to maintain blood in a liquid state and making it easy to remove from the circulatory system
- inhibit or stop the clotting of blood
buffers
- agents that serve to control the acid base balance of fluid and tissues
- stabilize the acid base balance of the fluid, also maintain the balance of the pH in the tissues when the embalming fluids react with cellular proteins
disinfectants
- germicides are incorporated into the arterial fluids, some co injections fluids, cavity fluids, and surface ____
- be sure that formaldehyde is removed from the area as much as possible before working with ____ containing strong oxidizers
formadlehyde
- acts harshly on the body tissues, does not diffuse/distribute well
- dehydrates, darkens, and grays body tissues
discovered by Alexander Butlerov in 1859
formalin
formaldehyde generally available as ____; aqueous solution containing 37% formaldehyde gas by mass in water
glutaraldehyde
- relative imperviousness of reaction rate to pH changes, particularly in the alkaline range
- Will react with protein at higher pHs that would essentially render formaldehyde inactive
humectants
- agents that help control tissue moisture balance
- increases the capability of embalmed tissue to retain moisture
- include glycerin, sorbitol, glycols, and other polyhydroxy alcohols
inactive dyes
- give color to fluids
- non cosmetic
modifying agents
- Buffers
- Anticoagulants
- Surfactants
- Humectants
- control the rate of action of the main preservative chemicals in embalming formulations
paraformaldehyde
- polymer of formaldehyde, a white powdery solid containing 85-99% formaldehyde
- used when powdered preparations are involved, such as hardening compounds or used for “dusting” body walls and viscera
perfuming agents
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
phenol
- also carbolic acid
- classified as a preservative and germicide
- most found components of both arterial and cavity fluids in early days of fluid industry
preservatives
- chemical compounds classified under “preservative or fixative chemical” agents in the chemical preservative solution which react with proteins
surfactants
- wetting agents, surface tension reducers, penetrating agents, or surface active agents
- reduces the molecular cohesion and surface tension of a liquid so it can flow through smaller apertures
vehicles
- liquid that serves as a solvent for embalming fluids
- Must be a solvent or mixture of solvents that keep the active substances in a stable and uniform state during the transport through the circulatory system to all parts of the body
cavity fluid
- concentrated embalming chemical injected into the cavities of body following the aspiration of the body, - can also be used in hypodermic and surface embalming
co injection fluid
- primarily used to supplement and enhance the action of vascular solutions
- Designed to enhance the distribution and effectiveness of the arterial solution
hypertonic solution
if a solution contains a greater quantity of a dissolved substance than is found in the blood, it is said to be ____
hypotonic solution
if a solution contains less of a dissolved substance than is found in blood, it is said to be ____
pre embalming analysis
the strength and volume of the initial arterial solution is determined by this
pre injection fluid
- supplemental fluid that may be injected before the injection of preservative arterial solution
- Expand vascular system, promotes drainage, prepare the tissues for reception of preservative arterial solution
preservative demand
amount of preservative (formaldehyde) required to effectively preserve and disinfect remains. This amount depends on the condition of the tissues as determined in the embalming analysis
primary dilution
concentrated arterial fluid is added to water to form the arterial solution
secondary dilution
weakening of the strength of the arterial solution by vascular and interstitial fluids
