Major Recovery Surgery

A surgical intervention that penetrates a body cavity (i.e. cranial, thoracic, abdominal, synovial, pelvic, ocular or orbital, skeletal, joint or bone marrow), involves extensive tissue dissection or transection, or has the potential for producing a substantial impairment of a physical or physiological function.

Examples of major survival surgeries include:

  • Tendon/ligament repair or injury
  • Ovariohysterectomy
  • All --otomies (e.g., lararotomy, tracheotomy) and --ectomies
  • -Oscopies that involve incision (e.g., laparascopy)
  • Implantation of central devices
  • Amputation
  • Enucleation
  • Eye surgery involving corneal incision
  • Central cannulation (central approach)
  • Musculoskeletal system repair, injury, or biopsy
  • Extensive tissue dissection/transection (e.g., nerve or muscle cut-down)

Some surgeries may be classified as major or minor depending on various factors, and may be evaluated on a case-by-case basis.

  • Factors that can influence the classification may include the duration of anesthesia, size and location of the incisions, amount of tissue dissection and characteristics of the animal to undergo surgery.

Manipulation

A change in the composition of the normally offered food or water. This can include addition or deletion of a nutrient in an animal diet and/or addition of a compound, medication or other substance to the food or drinking water provided to the animal.

All personnel must be enrolled in the Animal Handler Medical Surveillance Program if they will perform the following tasks:

  1. Handles, restrains, collects specimens from, or administers substances to, live vertebrate animals.
  2. Does not conduct procedures on live animals, but handles animal waste, "unfixed" animal tissues, non-sanitized animal caging/enclosures, or body fluids.
  3. Observes animals or enters animal facility only. No direct contact with animals: inspector, maintenance personnel, etc.

Departments with personnel that meet the requirements of the program will be notified by the eRAM system to complete the Medical Surveillance Questionnaire.

Minor Recovery Surgery

A surgical intervention that does not expose a body cavity or that does not ordinarily have the potential to result in impairment of a vital physical or physiological function.

Examples of minor survival surgeries include:

  • Cranial burr holes that do not expose dura or brain
  • Subcutaneous implants
  • Peripheral vessel cannulation (peripheral approach)
  • Castration (scrotal or prescrotal approach)
