common used in the clinic
not commonly used
important characteristics
disinfectant only
must rinse cages and runs thoroughly before reintroducing animals
precautions
highly toxic to cats
highly irritating to tissue: causes irritation on contact.
class of disinfectant:
ALCOHOLS
members of this group
70% isopropyl alcohol
most commonly used.
40% ethyl alcohol
booze= 80 proof = 40%
Methyl alcohol = wood alcohol
common uses in the clinic
70% isopropyl alcohol
70% isopropyl alcohol:
common antiseptic on intact skin
A disinfectant used in thermometer holders.
Used to "swipe" skin before an injection
Used as a rinse when performing a surgical scrub on a patient.
Used to wet down the hair of animals to better visulize veins.
Sometimes applied over large areas to help cool an overheated patient down.
common used in the clinic
Wood alcohol
fixing blood smears onto microscope slides
Important Characteristics:
70% isopropyl alcohol
inactived by organic debrea.
Compatible with soaps and detergants
Must have 1-2 mins. contact time to be effective.
denatures, cooks 'proteins'
Contraindicated for use on broken skin
Evaporates leaving no residue.
Evaporation cools the body
Removes skin oil, helps clean the skin, helps tape stick.
Activity enhanced by Iodine and Quaternary ammonium compounds.
Percautions
70% isopropyl alcohol
highly irritating to open wounds.
Can be drying to the skin
Flammible.
Percautions
wood alcohol
Highly toxic
Can cause blindness if ingested.
Class of dininfectant:
Quaternary Ammonium compounds (quats)
n-alkyl Dimethyl Benzyl Ammonium Chloride
members of this group
Roccal-Plus
Benzalkonium Chloride (Benz-All
Parvosol
HDQ
common uses in the clinic
Benz-All
Benz-All is a popular cold pack disinfectant solution that contains a rust inhibitor.
important characteristics
Benz-All
supplied highly concerntrated.
Must use proper dilution or can be irritating, toxic and expensive.
important characteristics
Quats in general
must use proper dilution or can be irritation, toxic and expensive.
Inactiviated by organic debris (sanitize prior to application)
toxic to cats (rinse well and caution not to leave any puddles of solution in cages)
Activity enhanced by alcohol.
Precautions
Quats in general
toxic to cats (rinse well and caution not to leave any puddles of solution in cages
Class of disinfectant:
HALOGENS
one of two
Members of this group
Chlorine compound
5% sodium Hypochlorite=household bleach(Chlorox)
Also called a stock solution
common used in the clinic
primarily used as a disinfectant
as an antiseptic on intact skin
important characteristics
viruses it can kill
Requires several minutes of contact to be effective.
Kills a large number of organisms:
notably - PARVOVIRUS, FELINE LEUKEMIA VIRUS, HUMAN PATHOGENS LIKE HIV AND HEP B.
important characteristics
how it is used
1:32 dilution
1:32=1 oz bleach:32oz H2O
= 1oz:1 qt = 30 cc
1qt = 120 cc: 1 gal = 4oz:1 gal
common conversion factors
1 oz = 30 cc
8 oz = 1 cup
2 cups = 1 pt
2 pts = 1 qt
4 qt = 1 gal
1 qt = 32oz
1 gal = 128 oz
precautions
bleaches fabric and full strength solution will destroy fabric
will corrode metal
vapors are irritation and the solution can irritate skin
(good ventilation and rinse well)
Is inhibited by organic matter.
Class of Disinfectant
HALOGENS
two of two
member of this group
Iodine (I2) and
Iodophor (organic Iodine - an anion) compounds (iodide 4
The most common iodophor is Povidone-Iodine = Betadyne
common used in the clinic
Amoung the best and widely used topical and internal antiseptics
Used at a 10% dilution for irrigation of tissue
used at a 10% dilution on intact tissue as a scrub
Used full strenth but w/soap present as a surgical scrub soap.
important characteristics
Iodide ion (I-) is the active component of both Iodine and Iodophor.
Iodine alone is usually combined with Isopropyl alcohol to produce Tincture of Iodine.
Iodide combined with an organic molecule is called an Iodophor which releases I- when applied
important characteristics
how is it enhanced
enhanced by alcohol (tincture of iodine/surgical scrub = a povidon-iodine scrub followed by an isopropyl alcohol rinse and finally a povidone-iodine spray.
Important characteristics:
Iodine(i2) and Iodophor (organic Iodide) compounds
`Compatible with soaps and detergents.
In solution used as a 10% povidone-iodine solution.
Full strenth usually with soap, used as a surgical scrub.
Potenciated by alcohol.
important characteristic
excellent residual activity - inactiviated by organic material
Corrosive to metal (don't use in cold packs)
Concentrated solution are damaging to tissue.
10% is a common dilution for irrigation of tissue.
precautions
Cats are especially sensitive to povidone-iodine compounds.
Class of disinfectant
