Does Isoflurane Have Analgesic Properties?

Similar to many general anesthetics, the exact mechanism of the action has not been clearly delineated. Isoflurane reduces pain sensitivity (analgesia) and relaxes muscles. Isoflurane likely binds to GABA, glutamate and glycine receptors, but has different effects on each receptor.

Which anesthetic agent has analgesic effect?

Subhypnotic doses of thiopentone and propofol cause analgesia to experimentally induced acute pain. Cardiovascular responses to noxious stimuli during isoflurane anesthesia are minimally affected by anesthetic action in the brain.

Does isoflurane prevent pain?

Isoflurane reduces pain and inhibits apoptosis of myocardial cells through the phosphoinositide 3-kinase/protein kinase B signaling pathway in mice during cardiac surgery. Authors: Zhibing Pi.
