the concentrated preservative that will be diluted
with water to for the arterial solution for injection (IN THE
BOTTLE)
Arterial fluid
the in use solution composed of the
concentrated fluid diluted with water and other supplemental chemicals for injection (IN THE TANK)
arterial solution
chemicals injected into the body cavities following
aspiration
cavity fluid
fluid injected for purposes other than
preservation and disinfection; can be injected before the arterial solution or with the arterial solution
supplemental fluid
chemicals used in addition to vascular and cavity fluids; applied to the body surface
accessory chemical
fluids designed for with special body conditions
special purpose fluid
A saturated aqueous solution of formaldehyde which
contains 40% by volume and 37% by weight of formaldehyde by mass in water or methyl alcohol (wood alcohol)
formalin
-Formaldehyde that drops to the bottom of the container and is not available for chemical reaction
-White and powdery
-Prepared from water solutions of formaldehyde through
evaporation
paraformaldehyde
the amount of formaldehyde gas (in grams) present in 100 mL of concentrated fluid •High Index 26 36% •Medium Index 16 25% •Low Index 5 15%
index
- Compounds that are combined with certain aldehydes
- With certain catalysts give off formaldehyde at a slower rate
- By requiring certain catalysts, formaldehyde can be better distributed
donor compounds
particularly effective in an alkaline pH
glutaraldehyde
•Crystalline solid at room temperature
•Soluble in water
•Weakly acidic
•Preserves by penetrating cellular phospholipid bi layer
•Dissociates cytoplasm of the cell
•Mainly used in cavity fluid and surface applications for
bleaching
phenol
•Chiefly used for germicidal and deodorizing properties
•Not compatible with wetting agents or coloring agents in
fluids
•Mainly used in cavity fluids and cold sterilization formulas
•Examples are roccal and zephrin chloride
quats
- Used to dilute and dissolve chemicals
- Must keep embalming chemicals in a stable state
- Water
- Methyl and Ethyl Alcohols
vehicles
- Cosmetic
* Non cosmetic
dye
chemicals added to the embalming solution to deal with
varying demands predicated upon the type of embalming, the environment, and the embalming fluid to be used
modifying agents
substances in a solution that are capable of
neutralizing, within limits, both acids and bases and thereby
maintaining the original, or constant pH of the solution
•Balance pH in embalming fluids
•Balance pH in decomposing tissues
buffers
chemicals that increase the capability of
embalmed tissue to retain moisture
•Protects formaldehyde from reacting too soon
•Brings about cellular hydration
•Make tissue flexible and rubbery
humectants
chemicals that retard the tendency of blood to become more viscous through natural post mortem processes and prevent any other adverse reactions between blood and embalming chemicals
anti-coagulants
Surfactants (wetting agents)
•Lowering the surface tension of embalming solution allows
for better delivery
•Lowering capillary attraction allows for the removal of blood
•Uniformity in filtering through the capillary walls
surfactants
- Supplemental fluid injection before the preservative solution
- Promotes drainage
- Prepares the tissues for the arterial solution
pre-injection fluids
Supplemental fluid that is mixed and injected along with the arterial solution
co-injection fluids
separate fluids or ones that enhance arterial fluids by the addition of special chemicals such
as humectants
•More viscous and heavy
•Used in dehydration cases
•Used to maintain hydration levels
•Colloidal humectants draw fluid out of the tissues depending on drainage technique
restorative fluids
- Helps reduce swelling
- Draws edema from tissues into venous drainage
- Can dehydrate
edema fluid
