(a) All persons who have been convicted of a capital offense and have had imposed upon them a sentence of death shall suffer such punishment by lethal injection. Lethal injection is the continuous intravenous injection of a substance or substances sufficient to cause death into the body of the person sentenced to death until such person is dead.

(b) In all cases in which the defendant is sentenced to death, it shall be the duty of the trial judge in passing sentence to direct that the defendant be delivered to the Department of Corrections for execution of the death sentence at a state correctional institution designated by the department.

(c) Notwithstanding any other provision of law, prescription, preparation, compounding, dispensing, or administration of a lethal injection authorized by a sentence of death by a court of competent jurisdiction shall not constitute the practice of medicine or any other profession relating to health care which is subject by law to regulation, licensure, or certification.

(d) No state agency, department, or official may, through regulation or otherwise, require or compel a physician to participate in the execution of a death sentence. "To participate in the execution of a death sentence" means any of the following actions: selecting injection sites; starting an intravenous line or lines as a port for a lethal injection device; prescribing, preparing, administering, or supervising injection drugs or their doses or types; inspecting, testing, or maintaining lethal injection devices; or consulting with or supervising lethal injection personnel.
