Low dose ketamin

Abstract

Ketamine binds non-competitive against a phencyclidine receptors bound N-methyl-D-aspartate (NMDA), a receptor that is involved in the pathophysiology of acute pain. Ketamine has been used as an intravenous anesthesia, analgesia for acute and chronic pain at a dose of subanaesthetic. Ketamine is a dissociative anesthetic produces a state with a characteristic strong analgesia, amnesia, and catalepsy. Dissociative components resulting from the effect on the limbic system and talamoneokortikal. Lowdose ketamine as known as analgesia dose ketamine or subanestesia dose is 0.2 to 0.75 mg / kg IV. At low doses, ketamine does not increase the effect psychomimetic like dissociation or deep sedation. The combination with midazolam provides satisfactory sedation, amnesia and analgesia without significant cardiovascular depression.
