Study Notes
Lab Work
- CBC & Chemistry should be performed on all anesthetic patients.
- FECAL tests should be performed on all anesthetic patients.
- HW or FeLV/FIV tests should be performed on all anesthetic patients.
Autoclave
- Chemical sterilization indicators are used when using autoclave bags
- Autoclave tape, culture test indicators, and chemical sterilization indicators are forms of autoclave effectiveness testing.
- Gravity displacement and prevacuum sterilizers are the two main types of autoclaves.
- Gravity displacement introduces steam from the top of the chamber, forcing air to the bottom.
- Prevacuum sterilizers evacuate air via vacuum pump prior to steam introduction, leading to faster and more even steam penetration.
- Complete sterilization is achieved when all materials are exposed to steam at the correct temperature and duration.
- 9-15 minutes of exposure at 121 degrees C (250 degrees F) are necessary to destroy all microorganisms.
Cross Matching
- Red blood cells (RBCs) are "washed" multiple times to remove extraneous elements like WBCs, microfilaria, platelets, and factor VII for accurate testing.
- Coverslips help distinguish rouleaux from auto-agglutination by applying weight on the sample, potentially breaking apart rouleaux.
- Auto-agglutination occurs when a recipient's RBCs clump together due to their own antibodies.
- Schistocytes are fragmented RBCs, indicating that the patient's body is attacking its own cells.
- Blood transfusions are contraindicated when the recipient's blood displays auto-agglutination or schistocytes.
- The major cross-match involves mixing 1 drop of donor RBCs with 2 drops of recipient plasma.
- The minor cross-match involves mixing 1 drop of recipient RBCs with 2 drops of donor plasma.
- Agglutination during cross-matching indicates incompatibility.
- Domestic shorthair cats are most commonly Type A blood.
- Auto-controls in blood crossmatching help rule out recipient auto-agglutination.
- Intravenous administration is the preferred route for blood transfusion therapy.
- Blood product filtration traps cellular debris, minimizing adverse reactions.
- Cryoprecipitate is used to treat hemophilia A.
- Steam under pressure is the agent used for autoclave sterilization.
