Study Notes
Anesthesia & Analgesia in Laboratory Animals
- Familiarize with the SLA Anesthesia Formularies for appropriate guidelines and protocols.
- All laboratory procedures must have prior approval from the Institutional Animal Care and Use Committee (IACUC) to ensure ethical standards are met.
- Mice and rats have unique surgical and anesthesia requirements, necessitating specialized knowledge.
- Laboratory animal medicine is governed by specific regulations to ensure animal welfare.
- Pain management in lab animals is mandatory; they must receive treatment for pain relief.
Types of Anesthesia
- Understand the advantages and disadvantages of both inhalant and injectable anesthesia methods.
- Proper documentation is crucial; lack of documentation means the procedure is considered not to have occurred at all.
Surgical Classification in Laboratory Animals
- Surgery is classified as major or minor based on the degree of invasiveness and impact on animal physiology.
- Major surgery involves entering the body cavity or significantly impairs movement or physiological function.
- Minor surgery refers to procedures that do not enter body cavities and do not cause significant impairments.
- Surgical procedures may be categorized as either survival or non-survival:
- Survival surgery: the animal regains consciousness after the procedure.
- Non-survival surgery: the animal is euthanized while under anesthesia.
Implant Procedures
- Implants may involve the placement of intravenous access ports or other devices critical for study continuity and animal health.
