Lipid peroxidation in rat lung induced by neuroleptanalgesia and its components.

The aim of the present work was to determine the likelihood of lipid peroxidation in the lungs of rats subjected to neuroleptanalgesia and its components. In particular, the effect of fentanyl, droperidol, a nitrous oxide/oxygen mixture when used separately or in combination, on the lung level of lipid peroxidation was investigated. The in vitro antioxidant properties of fentanyl and droperidol were also tested.

Nitrous oxide with fentanyl and droperidol minimizes lipid peroxidation in the liver.

We have studied the level of lipid peroxidation in the liver of rats exposed to nitrous oxide plus oxygen or injected with droperidol of fentanyl. The effect of nitrous oxide used in combination with droperidol and fentanyl was also investigated. All the tested anaesthetics caused lipid peroxidation in the rat liver.
