ATLANTA - A failed execution in Tennessee is raising new questions about lethal injection protocols - including in Georgia, where lethal injection remains the state's only currently used method of execution. Christa Pike remains in critical condition after Tennessee officials administered two doses of pentobarbital during an attempted execution that did not result in her death. An Atlanta anesthesiology professor says he warned Tennessee officials before the execution that Pike's medical history could create complications with the lethal injection process. Dr. Joel Zivot says Pike's blood-clotting disorder and history of difficult IV access raised concerns about whether the execution drugs could be properly administered. I was not shocked, Zivot said of what happened. Zivot believes the pentobarbital may have entered the tissue surrounding Pike's vein instead of going directly into her bloodstream. So when the chemical was injected, instead of going into the circulation, it ended up as a quantity directly into the tissue in her arm. And this caused a significant burn, Zivot said. Media witnesses at the execution reported hearing Pike say that an area was burning and hurting and ask whether that was normal. Zivot also believes Pike may have suffered a brain injury caused by a lack of oxygen during the attempted execution. What does this mean for Georgia? Georgia uses the lethal injection method like Tennessee. The Georgia Department of Corrections tells Channel 2 Action News it continuously reviews its lethal injection process and is confident in its protocols and medical teams. Georgia's execution protocol allows for additional doses of the execution drug if a person does not die after the first dose. However, the protocol does not specify a procedure for resuscitating someone after failed execution attempts. That is raising questions about what would happen if a lethal injection in Georgia did not go as planned.
