Embalming Q2
Embalming Chemicals
Question | Answer |
---|---|
chemicals which inactivate saprophytic bacteria, render unsuitable for nutrition the media upon which such bacteria thrive, & which will arrest decomposition by altering enzymes and lysins of the body as well as converting the decomposable tissues into a | preservatives |
alcohols | ethyl methyl isopropyl |
types of preservatives | aldehydes alcohols phenol & phenolic compounds inorganic salts |
characteristics of phenol | very soluble very toxic & irritating "grandaddy" of germicides excellent preservative used on cadavers |
aldehydes | formaldehyde gluteraldehyde |
gluteraldehyde | less irritating to skin & eyes less dehydrating automatically causes less firming of tissue without sacrificing preservation more efficient no OSHA regs against fumes more expensive |
purpose of inorganic salts | used for osmosis |
inorganic salts | sodium chloride potassium nitrate sodium carbonate sodium sulfate |
chemicals which kill or render incapable of reproduction pathogens | germicides |
quaternary ammonium compounds | zephiran chloride roccal |
chemicals which retard the tendency of blood to become more viscous by natural postmortem processes or prevent adverse reactions between blood & embalming chemicals | anticoagulants |
precipitants | sodium citrate sodium oxylate calcium oxylate |
sequestering agents | TDA (tetrasodium diacetic acid) EDTA (ethylene diamine tetracetic acid) |
chemicals that isolate individual calcium ions, rendering them unresponsive | sequestering agents |
liquids which serve as a solvent for all ingredients in embalming solution | vehicles |
chemicals which reduce the molecular cohesion of a liquid & thereby enable it to flow through smaller apertures | surfactants |
other names for "surfactant" | wetting agent surface tension reducer penetrating agent surface active agent |
types of surfactants | sodium lauryl sulfate* sulfonates |
substances which will, upon being dissolved, impart a definite color to the solvent | dyes/coloring agents |
types of dyes | eosine carmine ponceau red erythrosine |
chemicals having the capability of displacing an unpleasant odor or of altering an unpleasant odor to a more pleasant one | reodorants/deodorant (perfuming agent) (masking agent) |
type of perfuming agents | methyl salicylate (oil of wintergreen) |
chemicals that alter the way formalin works | modifying agents |
types of modifying agents | humectants buffers water-conditioning agents |
chemicals creating an increased capability for embalmed tissue to retain their moisture | humectants |
types of humectants | glycerol (alcohol) sorbitol (alcohol) lanolin (from sheep) aloe (from plants) hexylene glycol (waxy) |
chemicals which affect a stabilization of the acid-base balance within embalming solutions & embalmed tissues | buffers |
types of buffers | borax & boric acid sodium bicarbonate sodium citrate EDTA disodium phosphate |
chemicals added to water for primary dilution | water-conditioning agents (water softeners) |
types of water-conditioning agents | sodium citrate EDTA sodium oxylate |
chemical which is a precipitant (anticoagulant), a buffer and a water-conditioning agent | EDTA |
chemical which is a precipitant (anticoagulant) and a water-conditioning agent | sodium oxylate |
high index fluids (30-40) used for edema cases & decomp cases which contain added germicides & tissue coagulants | dehydrating fluids & firming fluids |
