Uncruel and Usual Capital Punishment, Part Three

From the Clark County (Indiana) prosecutor:

LETHAL INJECTION

Procedure: State statutes typically provide: "The punishment of death must be inflicted by continuous, intravenous administration of a lethal quantity of an ultrashort-acting barbiturate in combination with a chemical paralytic agent until death is pronounced by a licensed physician according to accepted standards of medical practice."

The execution protocol for most jurisdictions authorizes the use of a combination of three drugs. The first, sodium thiopental or sodium pentothal, is a barbiturate that renders the prisoner unconscious. The second, pancuronium bromide, is a muscle relaxant that paralyzes the diaphragm and lungs. The third, potassium chloride, causes cardiac arrest. Each chemical is lethal in the amounts administered.

The inmate is escorted into the execution chamber and is strapped onto a gurney with ankle and wrist restraints. The inmate is connected to a cardiac monitor which is connected to a printer outside the execution chamber. An IV is started in two usable veins, one in each arm, and a flow of normal saline solution is administered at a slow rate. One line is held in reserve in case of a blockage or malfunction in the other. At the warden’s signal, 5.0 grams of sodium pentothal (in 20 cc of diluent) is administered, then the line is flushed with sterile normal saline solution. This is followed by 50 cc of pancuronium bromide, a saline flush, and finally, 50 cc of potassium chloride. (See California Execution Procedures).

The most common problem encountered is collapsing veins and the inability to properly insert the IV. Some states allow for a Thorazine or sedative injection to facilitate IV insertion.

History: Lethal injection had first been proposed as a means of execution in 1888 when New York considered it but ultimately opted for electrocution. In 1977, Oklahoma became the first state to adopt lethal injection. Texas performed the first execution by lethal injection in 1982 with the execution of Charlie Brooks.

Current Application: 17 states and the federal government authorize lethal injection as the sole method of execution. 20 other states provide for lethal injection as the primary method of execution, but provide alternative methods depending upon the choice of the inmate, the date of the execution or sentence, or the possibility of the method being held unconstitutional. As of July 1, 2006, 861 of 1,029 (81%) executions performed since 1976 have been by lethal injection, including 375 of the last 378 executions.
