Multiple Major Survival Surgeries – The Guide And USDA AWA Regulations And Standards, Section 2.31
From the Guide,
“Regardless of classification, multiple surgical procedures on a single animal should be evaluated to determine their impact on the animal’s wellbeing. Multiple major surgical procedures on a single animal are acceptable only if they are (1) included in and essential components of a single research project or protocol, (2) scientifically justified by the investigator, or (3) necessary for clinical reasons. Conservation of scarce animal resources may justify the conduct of multiple major surgeries on a single animal, but the application of such a practice on a single animal used in separate protocols is discouraged and should be reviewed critically by the IACUC.”
