Abstract/OtherAbstract:
The potential toxicity of halogenated anaesthetics on cellular immunity has been investigated on guineapig macrophages in gas phase by measuring the adenosine 5' triphosphate (ATP) concentration in the macrophages. A toxicity index (TI) was obtained by comparing the ATP concentration in vapour or gas-exposed macrophages with that of control cells. The TI for 5% halothane in air after 24 h was 31.2 +/- 8.3%. The TI for 5% enflurane in air was 12.7 +/- 6.6% (P less than 0.01). In an oxygen-enriched gas mixture (60%), the halothane TI increased to 65 +/- 6.6%, whereas that for enflurane remained at 15.4 +/- 16.9% (P less than 0.01). In macrophages exposed to 1% halothane, or 2% enflurane, in 50% nitrous oxide in oxygen, for 3 and 6 h, the halothane TI (0.4 +/- 3.3%) and the enflurane TI (2.5 +/- 4.1%) did not differ significant from the control group after 3 h. However, after 6 h exposure the halothane TI (31.3 +/- 9.6%) and the enflurane TI (17 +/- 20%) were different (P = 0.05) from control. It is concluded that the prolonged administration of high concentrations of halothane and enflurane alone decreased macrophages ATP concentration. A high concentration of oxygen in the gas mixture increased significantly the halothane TI.
