quiz 1 Flashcards
the four distinct processes of arterial embalming
injection, distribution, diffusion, and drainage
two primary functions of arterial embalming
injection of preservative solution and drainage
blood drainage
5-6 quarts of blood in a 160lbs person witch is around 8% of body weight
blood drainage
when person dies 85% of blood is in capillaries, 10% in veins, and 5% in the arteries
drainage method - alternate
solution never injected while drainage is being taken
drainage method - concurrent
injection and drainage occurs at the same time
drainage method - intermittent
injection continues throughout embalming and drainage is shut off for selected short periods
the purpose of drainage
make room for arterial solution, reduce a secondary, dilution of arterial fluid, remove intravascular blood discoloration, remove a tissue that rapidly decomposes, remove an element that speeds decomposition,…..
instant tissue fixation
high strength solution injected in specific regions using short bursts under high pressure
multipoint injection
injection from 2 or more sites
multipoint injection
supplements the primary injection site when arterial solution cannot reach a particular area or when the area is insufficiently preserved
multipoint injection
suitable arteries are located closer to the area insufficiently embalmed
multipoint injection
advantages: increases the overall effectiveness of embalming, sectional embalming, military regulations require use of multiple sites for long term preservation
one point injection
uses the same site for both arterial injection and blood drainage
one point injection
suitable when embalmer anticipates uncomplicated distribution of embalming solution and favorable blood drainage
disadvantages of one point injection
short circuiting of arterial solution - takes path of least resistance
disadvantages of one point injection
can lead to shell embalming - embalming of the surface and not deeper tissues
restricted cervical injection
effectively controls volume fo arterial solution entering head and face
restricted cervical injection
prevents facial distension and dehydration when large volumes of strong solution are required to meet the preservative demands in trunk of body
restricted cervical injection
good for bodies with facial trauma, eye enucleation, etc
six point injection
anticipating embalming challenges (poor distribution, incomplete blood drainage, increased probability of tissue distension)
drainage contents
composed of blood, blood clots, interstitial and lymphatic fluid, and embalming solution
- estimated 50% or more of drainage during embalming is embalming solution
- initial drainage most dangerous
