Liquid Chromatography-Tandem Mass Spectrometry for Quantitation of Serum Pentobarbital.

Pentobarbital is a short-acting barbiturate with anticonvulsant and sedative-hypnotic properties. Pentobarbital may be used to induce sedation, control seizures, induce coma, and to manage patients with traumatic brain injury. In traumatic brain injury, use of pentobarbital is known to reduce both cerebral blood flow and oxygen consumption, which reduces intracranial pressure and cerebral ischemia.
