Moisture Absorbers (Sealing Compounds)

30
Q
  1. Powders

A

Two Kinds of Moisture Absorbing Sealing Agents

31
Q

Various types of dry powder gums that rapdily absorb all moisture in the area and then form a glue-like substance which inhibits leakage. These are dehydrated gums that are water soluble and turn to glue when they contact moisture. Put inside the incisions.

A

Powders (Moisture Absorbing Sealing Compounds)

32
Q

These are clay-like creams similar to putty or caulk that react with moisture to form a kind of cement.

A

Creams of Clays (Moisture Absorbing Sealing Compounds)

33
Q

Liquid adhesives that are used to paint over or mask incisions, cavities, or raw surfaces. Unlike moisture absorbents, these are applied to the surface. Put outside the incisions.

  2. Mold preventative agents or preservative jelly
  3. Any good bleaching cavity fluid used with absorbent cotton (Bleaching agents)
A

Three Types of Pack Applications

48
Q

(Must read the MSDS sheet, some cannot be used as surface packs).

  1. As a bleaching agent
  2. To deter further desquamation
  3. Treat wet and dry gangrene

  5. Surface or osmotic embalming
  6. To dry and harden lesions for restorative art work.
  7. As a reducing agent to reduce swelling puffed eyelids.
  8. To dry, harden and preserve excisions, skin flaps, cavity walls on autopsied cases.
A

Uses of Pack Applications

49
Q
  1. Thoroughly cover area to be treated with liquid, jelly, cream or mist depending upon the product.
  2. For surface embalming, saturate absorbent cotton; also saturate area to be treated.
  3. Cover the entire are with plastic to contain fumes- casket wrapper, dry cleaner’s bag, or saran wrap.
  4. Monitor pack application every three or four hours; noticeable firming will take place.
A

Application of Pack Application

50
Q

Especially watch the eyelids because this can cause sunken eyelids.

A

Pack Application

51
Q

To offset and lighten the tissues affected by postmortem stain and/or ecchymosis/bruising.

A

Purpose of Bleaching Agents

52
Q

This causes postmortem stain.

A

Hemolysis

53
Q

Surface packs, hypodermic injection or co-injection into the vascular system in arterial fluid solutions (rare).

A

Application of Bleaching Agents

54
Q
  • Phenol
  • Cresol
  • Oxidizing Agents
A

Components of Bleaching Agents

55
Q

Always check the lable of these to make sure they have bleaching capability (Check MSDS)

A

Cavity Fluid

56
Q

This is to hypodermically inject solicone or massage cream into the layers of the tissue, only after arterial injection, to build up and restore the natural contours of the face and hands. Used after the body is embalmed.

A

Tissue Builder

57
Q
  • Always keep the top on bottle
  • Keep needles clean with solvent (leave a little in needle)
  • Massage cream is easier to correct- requires a larger gague needle.
A

Notes on Tissue Builder

58
Q
  • Component: phenol, alcohol and formaldehyde
  • Is in disproportionate quantities because phenol and HCHO don’t mix well.
A

Triple Base Fluid

59
Q

Any combination of the two components:

  • Phenol and HCHO (disproportionate amounts, never 50/50)
  • Alcohol and HCHO
  • Again are in disproportionate quantities
A

Double Based Fluid

60
Q
  • Inactivate saprophytic bacteria
  • Render the medium for which bacteria survive undesirable.
  • Alter enzymes and lysins of the tissues to make them less suspectible to decompose.
A

Role Preservatives Play in Temporary Preservation

61
Q
  • The chemical acts directly on the protein of which the microbe lives.
  • The chemical acts directly on some bacteria but usually not spores.
A

Role Germicides Play in Temporary Preservation

62
Q

Some preservative chemicals may also act as _____.

A

Germicides

63
Q
  1. Active Dyes
  2. Passive Dyes
A

Two Types of Dyes

64
Q

Impart a stain into the tissue to create a more lifelike appearance in the deceased.

A

Active Dyes (Cosmetic Dyes)

65
Q

So that the embalmer can easily distinguish the difference of various chemicals. If the embalmer accidentally mistook a bottle of cavity fluid for a humectant, the results but be devastating.

A

Passive Dyes

66
Q
  1. Held keeps blood in a liquid state during arterial embalming.
  2. Reduces the minerals in the water.
  3. Active dyes are most effective when they are in a base environment.
  4. HCHO preserves better in an alkaline environment.
A

The 4 Purposes of Water Conditioners
