..embalming Flashcards
(128 cards)
What are the different types of embalming chemicals we discussed?
vascular (arterial) fluids cavity fluids pre-injection fluids co-injection fluids jaundice fluids hardening compounds preservative powders sealing agents surface applications
injected to disinfect, temporarily preserve and restore the dead human body without causing objectionable change in the tissues
vascular (arterial) fluids
vascular (arterial) fluids are generally classified by what?
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.)
strong (high) index
A strong or high index would consist of ____% by weight and ___ % by volume
3740
having an index of 19 - 27.Sometimes referred to as semi-firming or cosmetic fluid. Active shades of orange or red dye. (Oil based / cosmetic fluid). Results in a moderate firming of tissues. Normal Cases
medium (cosmetic arterial fluid)
any fluid with an index of 10 - 18. Produces a minimum firmness of tissues.
Infant cases or adults 80 lbs or less
weak
What are the components of vascular (arterial) fluids?
preservative supplementary germicide anticoagulants vehicle perfuming agents, deodorants, or masking agents dyes surfactants modifying 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 acids
- Inhibits further decomposition
- Inactivates some enzymes
- Kills some microorganisms – not all
- Destroys odors
examples of preservatives
aldehydes
alcohol
phenol
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
gas soluble formula water saturation
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 –
