A 40-year-old man taken to a local hospital after he fell and hit his head Wednesday night had a blood alcohol content of 0.57, police said.
"They keep surprising us how far they can go" with alcohol consumption, said Christopher Tompkins, executive assistant at the DUI Victim Center of Kansas.
His alcohol content was more than seven times the legal limit of 0.08.
The man's girlfriend reported that she was in the bathroom when she heard "a loud thump" at his home in the 3000 block of East Longview at about 9:30 p.m. Wednesday, police said.
When she came out of the bathroom, she found her boyfriend lying on the floor. He accused her of hitting him from behind, but police said there was no evidence to support his claims.
He was taken to a local hospital, where he needed eight staples to close the wound on the back of his head. He was held for observation because he was so heavily intoxicated.
"I doubt that even he knows how much he drank," Tompkins said of the man.
Blood alcohol levels of 0.40 or higher are generally toxic, Police Capt. Darrell Atteberry said.
For someone to have such a high blood alcohol content without passing out or dying takes "years of conditioning," Tompkins said.
"This is surely a rare thing," he said. "Thankfully, we don't see that many high ones."
A woman in Oregon had a blood alcohol level of 0.72 last year, he said.
