[Effect of halothane on the energy metabolism of isolated perfused rat kidney as analysed by 31P-NMR].

The effects of halothane on energy metabolism of isolated perfused rat kidney were studied by 31P-NMR spectroscopy. Rat kidney was perfused by physiological medium containing halothane. Perfusion was carried out continuously in addition to ischemic period of 30 or 10 minutes. In continuous perfusion study, halothane concentration below 4% did not affect renal ATP level but halothane above 6% decreased ATP level significantly. In ischemic study, changes of renal energy metabolism were not influenced by halothane below 4% throughout the experiment, but halothane above 6% decreased ATP levels significantly after reperfusion. From the viewpoint of energy metabolism, it can be said that a low concentration of halothane does not damage renal cells but a high concentration of halothane has possibility to damage them. During and after ischemic insult, halothane does not diminish renal damage, but on the contrary a high concentration of halothane reversely worsens it.
