26 fully unconscious and incapable of experiencing pain within 20 to 30 seconds. Id., at 299–301, 432–433. Dr. Zivot disagreed; but when he was asked how long he thought the twilight stage would last with pentobarbital, his testimony was evasive. Eventually, he said his “number would be longer than” 20 to 30 seconds, but he declined to say how much longer. Id., at 195. Instead, he referenced a 2015 study on euthanasia in horses. He said the study found that when horses were given a large dose of pentobarbital (along with other drugs), they exhibited “isoelectric EEG”—a complete absence of detectable brain activity—after 52 to 240 seconds. Id., at 194–196. The district court assumed Dr. Zivot meant that “pain might be felt until measurable brain activity ceases” and that, extrapolating from the horse study, it might take up to four minutes for pentobarbital to “induc[e] a state in which [Mr. Bucklew] could no longer sense that he is choking or unable to breathe.” The district court acknowledged, however, that this might be “a generous interpretation of Dr. Zivot’s testimony.” Id., at 822, and n. 5.

In fact, there’s nothing in the record to suggest that Mr. Bucklew will be capable of experiencing pain for significantly more than 20 to 30 seconds after being injected with pentobarbital. For one thing, Mr. Bucklew’s lawyer now admits that Dr. Zivot “crossed up the numbers” from the horse study. Tr. of Oral Arg. 7–8, 11–12. The study actually reported that the horses displayed isoelectric EEG between 2 and 52 seconds after infusion of pentobarbital was completed, with an average time of less than 24 seconds. App. 267. So if anything, the horse study appears to bolster Dr. Antognini’s time estimate. For another thing, everyone now also seems to acknowledge that isoelectric EEG is the wrong measure. Dr. Zivot never claimed the horses were capable of experiencing pain until they reached isoelectric EEG. And Mr. Bucklew’s lawyer now concedes that doctors perform major surgery on
