Thiopenta

Barbiturates Thiopental shall be used to produce anesthesia prior to the administration of additional general anesthetics, as well as to induce anesthesia by the application of a small amount of careful stimulation for brief operations, diagnosis, or therapy. Thiopental is an ultrashort-acting central nervous system depressant that induces hypnosis and anesthesia but not analgesia. In 30-40 seconds, it induces intravenous injection hypnosis. After a modest dosage, there is some somnolence and retrograde amnesia. Extended anesthesia as a reservoir for fatty tissues is aided by repeated intravenous dosages.

• Thiobarbiturate (thiopental sodium for injection) is the sodium counterpart of sodium pentobarbital.
