rrectly place or maintain IV lines,  they said in the filing.

Pike's attorneys said that hospital staff are working to save her life and clear the pentobarbital from her system.

 We are working closely with those closest to Christa to respect her wishes, safeguard her privacy and protect her rights as a patient during this extraordinarily difficult time,  said Luke Ihnen, one of Pike's attorneys.

Pike's lawyers previously called the botched execution  cruel,   torturous  and  predictable. 

 The state of Tennessee has shown us again that they are not capable of carrying out an execution consistent with basic human dignity,  attorney Randy Spivey told reporters Thursday.

Spivey has called on Tennessee Gov. Bill Lee to commute Pike's sentence. Her execution is currently on hold after Lee called off the remaining executions scheduled in the state for the rest of the year. He has ordered a  comprehensive, third-party review to determine exactly what happened. 

Pike was set to become the first woman executed in Tennessee since the 1800s after the Supreme Court ruled that her execution could proceed. She was sentenced to death for the 1995 murder of her former classmate, Colleen Slemmer.

According to court records, Pike and Slemmer were students at the Job Corps Center in Knoxville when Pike, then 18, tortured and killed her, allegedly over comments Slemmer, 19, had made about her relationship. Pike is now 50.
