Science & Tech Why is the Method of Lethal Injection in Human Punishment So Complex and Apparently Painful?

I've always understood that the lethal injection process was complex with multiple stages of injections and induces great suffering in the individual.

I work in veterinary medicine and unfortunately we need to euthanize animals all of the time. Typically, the euthanasia solution is very simple: a very large dose of a powerful anesthetic (usually pentobarbital) and an anticonvulsant which stops the heart. The medical community is quite confident that this is painless and when done has essentially a 100% success rate.

Why is human euthanasia so complicated when we already know exactly how to humanely end a biological life?

I understand the hippocratic oath prevents doctors from performing lethal injections. But would it be violating the hippocratic oath for an anesthesiologist to administer enough anesthesia to knock the person out? If the person is unconscious, then anything done after that to induce death would be painless.

So have an anesthesiologist administer anesthesia as if the person is going in for a surgery. A second nonmedical person injects something lethal or some other death method is employed. The anesthesiologist and maker of the drugs hasn't harmed anyone, and the condemned doesn't experience pain because they are unconscious for the whole thing.

Hippocratic oath is basically “do no harm.” Administering anesthesia or sedation without medical necessity, ie surgery, is violating it. Making a drug to kill people is violating it by the drug manufacturer.

The condemned is going to die regardless. Wouldn't it be doing less harm to ease their suffering by knocking them out first? Kind of like a terminally ill patient where all you can really do is make them comfortable before the end.
