Methods: 42 non-smoking male and female turkish patients of ASA-risk I and II were included. The patients received an anaesthesia induction with 8% sevoflurane in 100% oxygen ("tidal volume methode") and 0,1 mg/kg BW vecuronium for neuromuscular block and endotracheal intubation. Anaesthesia was maintained with 2.0-2.5 sevoflurane in 60% N2O and 40% O2. Four 5 ml venous blood samples werde taken: before induction (control), 60 minutes, 24 hours and 5 days after sevoflurane anesthesia. Samples were prepared according to the periferic blood culture assay, modified by Morhead and co-workers, and levels of MI and SCE were examined. Results: 60 minutes after sevoflurane-anaesthesia a significant decrease of MI was found compared to controls (p < 0.01). This depression was lower after 24 hours (p < 0.05) and reversible after 5 days. SCE increased significantly during 60 minutes of anaesthesia (p < 0.001), was also lower after 24 hours (5.6 ± 2.4 vs. 4.4 ± 1.7) and returned to normal levels after 5 days (p > 0.05). Conclusion: The application of sevoflurane for anaesthesia may influence the cell division in humans and may have a mutagenic effect on DNA at the cell level, which is reversible.GermanAdolescentAdultAgedAnesthetics, InhalationCell DivisionChromosomesDNAFemaleHumansLymphocytesMaleMethyl EthersMiddle AgedMitosisMutagenicity TestsSister Chromatid Exchangeinhalation anesthetic agentneuromuscular blocking agentsevofluranevecuroniumanesthesia inductionarticlecell divisionchromosome aberrationclinical articlecontrolled studydrug effectfemalehumanhuman cellinhalation anesthesiamalemitosismutagenicitysister chromatid exchangeArticle10.1055/s-2005-861138
