Lethal Injection Under Scrutiny As Justices Agree to Hear Case

The Associated Press

JACKSONVILLE | Lethal injection was supposed to be the humane, enlightened way to execute inmates and avoid the pain and the gruesome spectacle of firing squads, the electric chair and the noose.

But now it, too, is under legal attack as cruel and unusual, with the U.S. Supreme Court agreeing this week to hear arguments that lethal injection can cause excruciating pain.

Some supporters of the procedure say the notion that inmates suffer is unproven. And they argue that there is nothing wrong with lethal injection itself; instead, they say, the problem is inadequately trained executioners.

In fact, the man who developed the procedure 30 years ago said it is similar to the simple injections given every day in hospitals.

"What causes it to go wrong is that the protocols aren't carried out properly," said Dr. A. Jay Chapman, former Oklahoma medical examiner.

If an execution is about as simple as an ordinary injection, what, then, can go wrong?

the process

In the three-drug process used by most of the 38 states that practice lethal injection, sodium pentothal is given first as an anesthetic and is supposed to leave the inmate unconscious and unable to feel pain. It is followed by pancuronium bromide, which paralyzes the inmate's muscles, and then potassium chloride, which stops the heart.

Foes of capital punishment argue that if inmates are not properly anesthetized, they could suffer extreme pain without being able to cry out.

That could happen in a number of ways: The executioner could inaccurately calculate the dosage needed for an inmate of a given body weight. Or the executioner could fail to administer the full amount, mix the drug improperly, or wait too long between giving the anesthesia and the lethal substance.

In Missouri, a doctor who participated in dozens of executions was quoted recently as saying he was dyslexic and occasionally altered the amounts of anesthetic given.

A botched execution in Florida last year illustrated another way lethal injection could go awry: Angel Nieves Diaz needed a rare second dose of chemicals - and the execution took twice as long as normal - after the needles were mistakenly pushed clear through his veins and into the flesh of his arm.

That left chemical burns in his arm that opponents say probably caused him pain.

During the process, Diaz appeared to grimace. But he did not specifically say he was suffering. And a state panel was unable to determine whether Diaz had been properly sedated or whether he felt pain.

There is no direct proof that inmates have suffered while undergoing lethal injection.

But opponents of lethal injection often cite a 2005 study in the British medical journal The Lancet indicating that the anesthetic can wear off before an inmate dies. The study involved 49 U.S. executions. In 21 of the deaths, the study found, inmates were probably conscious when they received the final drug that stops the heart.

what can states do?

One major issue is how to measure the inmate's level of consciousness after the anesthetic is given.

Execution opponents say they think North Carolina is the only state using a device common in operating rooms to measure brain activity.

The state Corrections Department anesthetizes the inmates and waits for their brain activity to dip to a level indicating they are sedated before pushing in the lethal drug.

Fordham Law School professor Deborah Denno said the problems she sees with executions cannot be easily fixed with technology.

"You need to get better people, get better drugs and have more scrutiny of the process," said Denno.

Similarly, Richard Dieter, executive director of the Washington-based Death Penalty Information Center, which opposes executions, said lethal injection is essentially "a medical procedure being performed by nonmedical persons. These are drugs and procedures borrowed from operating rooms."

But many states find it hard to get doctors to take part because the American Medical Association's code of ethics bars members from participating in executions.

Chapman scoffed at the idea that executioners need to go to medical school to do the job right, saying people could easily be trained.
