Welcome to the PLoS BlogBlogrollWho Links to Us?Lethal Injection: Current Controversies Resolved There is a concern that some inmates may be conscious, but paralyzed, during execution, because one of the three drugs used may have worn off, prior to death. Thirdly, no one has explained how the first drug could have worn off, within the time frame of execution. Or, how is it that the first drug was, somehow, improperly administered, but the second and third were not, when using the same lines and procedures? An Associated Press reporter correctly stated that "there is little to support those claims except a few anecdotes of inmates gasping and convulsing and an article in the British medical journal Lancet." (AP, "Death penalty foes attack lethal-injection drug", 7/5/05) The articles did not/could not identify one case where evidence existed than an inmate was conscious during execution. The Lancet article identified 21 cases of execution where the level of "post mortem" (after death) sodium thiopental was below that used in surgery and, therefore, may suggest consciousness was possible. A more accurate description would be all but impossible. Dr. Lydia Conlay, chair of the department of anesthesiology, Baylor College of Medicine (Texas Medical Center, Houston) said the extrapolation of postmortem sodium thiopental levels in the blood to those at the time of execution is by no means a proven method. "I just don't think we can draw any conclusions from (the Lancet study) , one way or the other." Unconsciousness occurs within the first 30 seconds of the injection/execution process. The injection of the three drugs takes from 4-5 minutes. Death usually occurs within 6-7 minutes and is pronounced within 8-10 minutes. The researchers also failed to note the much lower probability (impossibility?) that the murderer could be conscious, while all three drugs are coursing through the veins, concurrently. Does anyone not know this? The chemicals used in lethal injection, as well as their individual and collective results, at the dosages used, are also well known by medical and pharmacology professionals. And this? Further, lethal injection is not a medical procedure, but the culmination of a judicial sentence carried out by criminal justice professionals, the result of which is intended as death, the outcome of every case. The question mark from the title says it all. Skip the speculation: Some Reality From Hartford Courant, "Ross Autopsy Stirs Execution Debate----Results Cited To Counter Talk Of Pre-Death Pain", August 11, 2005 The below is a paraphrase of parts of that article, including some exact quotes. Results of the autopsy done on serial killer Michael Ross are being cited by several prominent doctors to refute a highly publicized article that appeared in The Lancet, the British medical journal, in April, 2005. Critics of the Lancet article say it does not account for postmortem redistribution of the anesthetic - thiopental. The redistribution, the critics say, accounts for the lower levels of thiopental on which Dr. Koniaris based his Lancet article conclusions that the levels of anesthetic were inadequate. The Ross autopsy results document this redistribution, bolstering the critics' assertions. Dr. H. Wayne Carver II, Connecticut's chief medical examiner, was aware of the controversial Lancet article before performing the Ross autopsy. As a result, he took the additional step of drawing a sample of Ross's blood 20 minutes after he was pronounced dead at 2:25 a.m. May 13. Carver took a subsequent sample during the autopsy, which began about 7 hours later, at 9:40 a.m. The 1st sample showed a concentration of 29.6 milligrams per liter of thiopental; the second sample showed a concentration of 9.4 milligrams per liter. The 1st sample was drawn from Ross' right femoral artery, and the second from his heart, which can account for some of the discrepancy. But Dr. Mark Heath, a New York anesthesiologist and one of the numerous doctors who have signed letters to The Lancet challenging the Koniaris article, said it clearly substantiates the postmortem redistribution of the thiopental. Dr. Jonathan Groner, a pediatric surgeon from Ohio said he interviewed a number of forensic toxicologists before adopting the view that thiopental in a corpse leaves the blood and is absorbed by the fat, causing blood samples taken hours after death to be an unreliable marker of the levels of thiopental in the body at the time of death. Groner described the Ross autopsy results as "a powerful refutation" of the Lancet-Koniaris study. Dr. Ashraf Mozayani, a forensic toxicologist with the Harris County Medical Examiner's Office in Texas, said the level of thiopental "drops quite a bit" after death. Even in the living, Mozayani said, thiopental levels decline rapidly after administration of the drug. She cited one study in which a patient was administered 400 milligrams of thiopental intravenously. After two minutes the concentration in the blood was measured at 28 milligrams, but dropped to 3 milligrams concentration 19 minutes after the anesthetic was injected. Mozayani said the declining concentration of thiopental cited in the Ross autopsy report "make sense." On The Lancet article, she said, "I don't think they have the whole story - the postmortem redistribution and all the other things they have to consider for postmortem testing." NOTE: I think that had and knew the whole story. They just didn't include it in their report(s). Medical groups cite that there is an ethical conflict for participation in the lethal injection process, because medical professionals have a requirement to "do no harm". "Execution by lethal injection, even if it uses tools of intensive care such as intravenous tubing and beeping heart monitors, has the same relationship to medicine that an executioner's axe has to surgery." ("Lethal Injection Is Not Humane", PLoS, 4/24/07) The PLoS Medicine editors have made the same point many of us have been making - similar acts and similar equipment do not establish any equivalence or connection. Obviously, execution is not a medical treatment, but a criminal justice sanction. The basis for medical treatment is to improve the plight of the patient, for which the medical profession provides obvious and daily exceptions. The basis for execution is to carry out a criminal justice sentence where death is the sanction. Justice, deterrence, retribution, just punishments, upholding the social contract, saving innocent life, etc., are all recognized as aspects of the death penalty, all dealing with the greater good. Lethal injection is not a medical procedure. It is a criminal justice sanction authorized by law. Therefore, there is no ethical conflict with medical codes of conduct and medical personal participating in executions. 40,000 to 100,000 innocents die, every year, in the US because of medical misadventure or improper medical treatment.

PROPER TRAINING I am unaware of evidence that shows criminal justice professionals are more likely to commit some error in the lethal injection process than are medical professionals in IV application. 1) see "Deaths from Medical Misadventure"at originally written May, 2005.
