Question: What is an appropriate IACUC response? Applaud the PI's entrepreneurial attitude and encourage other researchers to think about how they can use leftover animals to help fund their own work. Require that the animals be euthanized with an overdose of anesthetic after the trainees have completed their surgical task. The animals should not be allowed to regain consciousness or recover from the surgery. CASE STUDY: Recovery and Multiple Use* A nationally-known professor-surgeon affiliated with the University and a local Health Institute submitted an IACUC protocol proposal to use 10 pigs this year for a surgical training program. He would serve as PI on the project. After tranquilizing and anesthetizing the animal, each trainee would visualize and remove the gall bladder using an operating endoscope. They would do so after successfully completing computer and video visualizations and before attempting the technique in humans. They would perform the procedure under the direction of the professor, and would use aseptic technique. The pigs would recover from the procedure and the attending veterinarian would monitor the pigs' pain and prescribe post-operative analgesia if necessary. The protocol called for euthanasia approximately two weeks after the procedure when the pigs appeared fully recovered, but did not
