I don't know how much of a solution it is, but I think there could be some bureaucratic/authoritarian pushback against this kind of thing if the American Medical Association more stringently enforced its ethics rules relating to the Hippocratic Oath. As a baseline, medical procedures should be for the benefit of a patient and performed with their consent, otherwise they are inappropriate and a breach of professional ethics. This is already enforced stringently in one very narrow domain: licensed doctors cannot assist states in either conducting, or even planning the preparations for, their processes of death penalty by lethal injection. This has caused them some practical problems, because they basically have to get amateur doctors to give advice. The AMA's rationale is that executing someone is not a legitimate medical treatment, and definitely doesn't have consent. But this principle seems like it should apply more broadly than the fairly extreme case of actually executing someone.
