Study Notes
Surgical Requirements in Laboratory Animals
- Sterilize: Eliminate harmful agents on equipment and supplies using methods like steam autoclaving, ethylene oxide gas, or cold sterilization.
- Disinfect/Sanitize: Physically clean and remove harmful agents to the greatest practical extent.
- Aseptic Technique: Procedures to limit microbial contamination of the surgical site before and during surgery.
- Dedicated Workspace: A designated area free of unnecessary equipment and materials, easily accessible, and with limited traffic during procedures.
- Hood Space: Protective space around the patient for optimal procedures.
- Species/Procedures: Survival surgery (e.g., mice, rats; non-survival surgery (any species); and minor procedures (any species).
- Postponement: Other laboratory work should be postponed during surgery.
Surgical Definitions
- Survival Surgery: The animal recovers from anesthesia and the procedure.
- Terminal/Non-Survival Surgery: The animal is humanely euthanized while still under anesthesia.
- Major Surgical Procedure: Penetrates a body cavity or permanently impairs physical/physiological functions (e.g., laparotomy, thoracotomy, etc.).
- Minor Surgical Procedure: Does not penetrate a body cavity or permanently impair physical/physiological functions (e.g., subcutaneous osmotic pump placement, skin biopsy).
Facilities Requirements
- Dedicated Surgical Room: Designed room maintaining environmental conditions, sanitation standards, and strict adherence to surgical procedures.
- Species/procedures allowed: Mammals larger than guinea pigs undergoing major survival procedures.
- Guidance: Regularly clean floors, walls, and immediate surgical area to prevent contamination. Limit non-surgical room use.
Preparation & Procedures
- Pre-Operative Preparation: Sanitize, sterilize and store instruments appropriately.
- Surgical Instruments: Sterilize instruments prior to starting procedures. Date and store packs for up to six months; after that, resterilize. Use pressurized steam autoclave as the common sterilization method.
- Surgical Space: Clean/Disinfect all surfaces used in the procedure with appropriate disinfectants. Limit traffic to only necessary personnel.
Animal
- Location: Prepare animals away from the designated surgical area.
- Hair Removal: Remove hair from the surgical site and surrounding area to prevent contamination using an electric clipper or depilatory cream.
- Hair Removal Timing: Preferably immediately prior to surgery.
Skin Preparation
- Scrubbing: Use appropriate disinfectant (e.g., iodine or chlorhexidine) and 70% alcohol solutions on the skin, working from clean to dirty. Avoid using chlorhexidine on or around eyes.
- Frequency of scrubbing: Repeat three alternating scrubbing with solution followed by 70% alcohol.
- Drapes/Coverings: Sterile drapes are placed over the animal before surgery, allowing visualization and to maintain a sterile field if possible.
- Contact Time: Scrub for at least 5 minutes from fingertips to elbows, and multiple scrubbing is permissible.
Post-Scrubbing
- Surgical Attire: Use appropriate attire (cap, facemask, shoe covers, sterile gown) for the surgical procedure. Surgical attire may not be fully necessary for rodents.
- Aseptic Technique During Attire Change: If aseptic technique is broken, change affected articles (e.g., gown or gloves) immediately.
Basics for a Successful Surgery
- Anesthetic Depth: Appropriately assess and ensure adequate anesthesia before beginning procedure.
- Aseptic Technique Procedure: Maintain sterility of hands within the sterile field. If a breach in sterility occurs, replace contaminated items immediately.
- Tissue Handling: Perform gentle tissue handling to prevent infection and delayed healing.
- Closure Procedures: Use appropriate suture size, type, and patterns to prevent dehiscence and promote healing.
Closure Procedures
- Appropriate Suture Label: Understand suture size and type based on tissue and species, choosing appropriate material, type, and strength.
- Appropriate Suture Patterns: Utilizing simple interrupted patterns in most cases is recommended. Employ alternative patterns in high-tension areas.
Anesthetic Recovery & Post-Operative Procedures
- Monitoring: Monitor animals post-surgery and maintain appropriate recovery conditions (e.g., temperature).
- Suture/Staple Removal: Remove sutures/clips within 7-14 days after surgery depending on species and site.
- Reporting: Report and record the date of suture removal in the animal's records.
