Lethal Injection
When using lethal injection, the prisoner is bound to a gurney and a member of the execution team positions several heart monitors on his skin. Two needles are then inserted into usable veins, usually in the inmates arms. Long tubes connect the needle through a hole in a cement block wall to several intravenous drips. The first is a harmless saline solution that is started immediately. Then, at the warden's signal, a curtain is raised exposing the inmate to the witnesses in an adjoining room.
The prisoner is then injected with sodium thiopental, an anesthetic, which puts the inmate to sleep. Next flows pavulon or pancuronium bromide, which paralyzes the entire muscle system and stops the inmate's breathing. Finally, the flow of potassium chloride stops the heart. Death results from anesthetic overdose and respiratory and cardiac arrest while the prisoner is unconscious.
