From The Wrong Thing by Barry Graham:
They had given Jesus a mild sedative before they’d strapped him to the gurney. When they tried to put the catheters in his arm, they couldn’t find a vein. So they dissected his arm. This procedure, which is called “cutting down,” took about a half-hour. When it was done, the arm wasn’t recognizable as an arm, but there were veins, and catheters stuck in them. They bound what remained so he wouldn’t bleed to death. Then they wheeled the gurney, with Jesus strapped to it, into the execution room and left him there for twenty minutes.
