Policy on Surgery Location Requirements for Rodent, Aquatic, and Avian Species

The purpose of this policy is to outline location requirements for performing surgeries on avian, aquatic and rodent species at U-M.  

  • Background

    The Guide (Eighth Edition), states that aseptic surgery should be conducted in dedicated facilities or spaces, unless specific justifications are approved by the IACUC. The purpose of this policy is to outline location requirements for performing surgeries on avian, aquatic and rodent species at U-M.  

  • Glossary Definitions

    Survival Surgery

    A survival surgery is one in which the animal awakes from anesthetic following a surgical procedure, even if for a short period of time.

  • Policy

    Surgical procedures on non-mammalian aquatic species may be performed in animal rooms as long as the anesthesia and recovery tanks do not share or recirculate water to the housing tanks.

    For most survival surgery performed on rodents and birds, an animal procedure laboratory is recommended; the space should be dedicated to surgery and related activities when used for this purpose and managed to minimize contamination from other activities conducted in the room at other times.

    In general, rodent and bird surgeries should be performed outside of housing facilities; however, there are select situations in which it may be appropriate to conduct surgery in an area where animals are housed:

    • Procedures performed on animals that have been exposed to hazards and are being maintained in safety containment areas (e.g. ABSL-2 housing areas and higher) in order to ensure containment of the hazard;
    • Procedures performed on animals that have specific health statuses that require maintenance in dedicated facilities (e.g. nude mice);
    • And certain locations that have incomplete enclosures but still provide proper separation of the animal housing area and the surgical activity (e.g. NCRC B26 363C); animals are additionally housed in ventilated rack systems to prevent exposure to pheromones.

    Other situations may be reviewed and approved by the Attending Veterinarian or their designee and the IACUC on a case-by-case basis.
