Embalming QTR 2

Embalming QUiz 3

Categories of embalming chemicals Atertial, cavity, supplemental, accessory, sealers, pack applications
Arterial fluids Index, aldehyde/non-aldehyde, color, firming or non firming, dehydrating or non-dehydrating, special purpose
Indexes of arterial Low - 10-20 Medium- 20-28 High- 30-36
Special purpose arterials Jaundice, high index, dehydrating, tissue gas, germicidal, infant
Preservatives CHemicals that stop saprophtic bacteria by rendering unsuitable the media upon which they thrive which will arrest decomp
Aldehydes Formaldehyde, Gluteraldehyde
Advantages of gluteraldehyde less irritaing and dehydrating, less firming, good germicide, oshas does not apply
Disadvantages of gluteraldehyde more expensive, more tests are needed
Alcohols Methyl, ethyl, isopropyl
Phenol Soluable in water, very penetrating, used in cadavr prep, very preserving, very dehydrating
Inorganic salts Sodium chloride, Sodium Carbonate, Potassium nitrate, Sodium Sulfate
Germicides Kill or sterilze pathogens
Germicides examples Aldehydes, phenol, QUATS
Examples of QUATS Zephrin Chloride, Roccal
Anticoagulants Chemicals that retard the tendency of blood to become viscous
Precipants Remove calcium from blood Ex. Sodium citrate, sodium oxylate, calcium oxylate
Sequestering agents Fences off calcium to prevent clotting Ex. Tetrad sodium diacteic acid (TDA), ETDA,
Vehicles Liquids that serve as solvents. Water and Alochol
Surfactants Reduces surface tension to reduce friction and allows fluid in to smaller apatures Ex. Sodium lauryl sulfate and Sulfonate
Dyes Two types Active (cosmetic), inactive (only color the fluid, not body)
Types of dyes Eosine, carmine, ponceau red, erythosine
Deorderants/ Redoderants COver up or alter the smell
Examples of Deoderants/ reoderants Oil of wintergreen, oil of cloves, lemon oil, cherry oil, oil of sassafras, benzaldehyde
Modifiers CHemicals used to balance, supplement or compliment other fluids by reating moisture or softening coagulation
Humenctants Increase embalmed tissues ability to retain moisture
Examples of humectants Glycerol, sorbital, hexalene glycol, lanoline, aloe
Buffers Stabilize pH
Examples of Buffers Borax and Boric acid, sodium bicarnonate, disodium phosphate, sodium citrate and EDTA (last wto are also anticoagulants)
Water conditioners Chemicals that comabt, Ca, Mg and Fe (II)by sequestering them, do the same as anticoagulants
Examples of water conditioners Sodium Citrate, EDTA, Sodium Oxylate
Jaundice concerns Bilirubin+ O2 (in formaldehyde) = Biliverdin (green)
Special ingredients in jaundice fluid Low HCHO content, redcuing agents, bleaching agents, counter staining dyes, water
Special fluid (company definitions) High index, dehydrating, firming used in cases with high preservative demands,
Cavity Fluids High index for aspirating viscera, conatins stronger versions as arterial fluids. DO NOT DILUTE
Supplemental fluids Pre-injection/ co-injection
CO injection Added to arterial
Pre injection injected before areterial, also called primary injection fluid, cappilary wash, body conditioner
Pre injection fluids do clear body of blood, address acidity, rehydrates and expands system
Advantages of pre injection Improved diffusion, rehydrates, clears lividity
Disadvantages of preinjection more time, might cause water log, DO NOT USE during hot case or edema
Accessory Chemicals Hardening compounds, Sealing compounds, pack applications
Hardening compound components Hardening agents, Disinfectants, Moisture absorbers, fillers, mold preventative agents, embalming powders
Harding agents Plaster of Paris, AMmonium Chloride
Disinfectants Paraformaldehyde, Ammonium chloride
Moisture absorbers Saw, dust, clay, chalk
Fillers Perlyte, cellulose
Mold preventative agents Paraformaldhyde, paradichlobenzne
Embalming powders mostly paraformaldehyde
Sealing agents Provide barriers against leakage
Types of sealers Powder or liquid
Powders go into aretail incision
Liquid sealer coat outside of incision. Bonding adhesives or cauterizing agents, sprays and cream
Pack applications Gel or liquid for topical embalming
