Section 1

Question Answer
Action of preservative chemicalsinactivate chemical groups of proteins and amino acids, inhibit further decomp, inactivate enzymes, kill microorganisms, destroy odors
basic types of embalming fluidarterial fluid, cavity fluid, accessory fluids, autopsy chemicals

Section 2

Question Answer
most commonly used aldehydes in embalming fluidformaldehyde (mono) and glutaraldehyde (di)
why is methanol alcohol used moreboth preservative and antipolymerizing agent
funtion of phenoldisinfect, bleach, and cauterize
why is phenol not used in arterial solutionmixed with aldehydes produces grey color

Section 3

Question Answer
humectant moisture retaining agent
difference between cavity fluids and arterialcavity have no dyes and higher concentration of disinfectant
Buffersubstance that reists change of pH
pH of cavity fluid4.5-5.2
whats in prei-injectionantiocaugulant, surfactant, and humectant
Surfactantfacilitate flow of embalming chemicals into tissues
types of jaundice fluidmasking fluid (medium concentration of dyes and formaldehyde), bleaching fluid (light/bleaching agent with medium formaldehyde), nonformaldehyde fluid (no formaldehyde)
special perservative fluidmax concentration of embalming fluid used for advanced decomp
autopsy chemicalsparaformaldehyde (preservative, disinfectant), aluminum chloride (dehydrate, disinfect), alum (dehydrate disinfectant), cellulose (dehydrate agen, preservative), plaster of paris (dehydrate)
factors influence shelf lifetemp, time, pH, light

Section 4

Question Answer
Examples of buffersborax, sodium phosphate, citrates, sodium salts of EDTA
examples of humectantglycol (dihydroxy alcohols), glycerol (trihydroxal alcohol), sorbitol and other polyhydroxyl alcohold and LANOLIN COMPOUNDS
anticoagulant/water conditionercitrates and sodium salts of EDTA
most commonly used vehicleswater, methanol, glycerol
alcohols used in embalming fluidsmethanol, ethanol, isopropyl alcohol
supplementary germicidequarterary ammonium compounds (disinfect skin, oral, and nasal cavities)
examples of deaderantsbenzaldehydes; oil of cloves; oil of sassafras; methyl salicylate (oil of wintergreen)
examples of dyeseosin; erythrosin; (red); ponceau red (color fluid); amaranth (dark red brown)
example of surfactantsulfonate and Sodium Lauryl Sulfate
