This 65-page report reveals the slipshod history of executions by lethal injection, using a protocol created three decades ago with no scientific research, nor modern adaptation, and still unchanged today. As the prisoner lies strapped to a gurney, a series of three drugs is injected into his vein by executioners hidden behind a wall. A massive dose of sodium thiopental, an anesthetic, is injected first, followed by pancuronium bromide, which paralyzes voluntary muscles, but leaves the prisoner fully conscious and able to experience pain. A third drug, potassium chloride, quickly causes cardiac arrest, but the drug is so painful that veterinarian guidelines prohibit its use unless a veterinarian first ensures that the pet to be put down is deeply unconscious. No such precaution is taken for prisoners being executed.
