(a) When sentence of death is imposed by the court in any
criminal case, the punishment of death shall be executed by the
administration of a continuous intravenous injection of a lethal
quantity of an ultra-short-acting barbiturate, alone or in
combination with a chemical paralytic agent and potassium
chloride, or other equally effective substance or substances
sufficient to cause death, until death is pronounced by a
licensed physician according to accepted standards of medical
practice. The sentence of death shall be executed within the
time prescribed by law, unless, for cause shown, the court or
governor extends the time. Administration of the injection does
not constitute the practice of medicine.

     (b) If the execution of the sentence of death as provided
in subsection (a) of this section is held unconstitutional, the
sentence of death shall be executed by the administration of
lethal gas within the time prescribed by law unless for cause
shown, the court or the governor extends the time.
