Material and Methods: Sixty patients were scheduled for elective surgery. The patients were divided into three groups (Group D=desflurane, Group S= sevoflurane, Group P= propofol). The same induction agents were used for all groups. The anesthesia was maintained with an inhalation agent (1-1,5 MAC) or propofol (the starting dose 12 mg.kg(-1) of propofol infusion was reduced to 9, 6 and then 3-6 mg.kg(-1)). BAL was performed immediately after induction of anesthesia and surgical procedure with a fiberoptic bronchoscop. Blood pressures, oxygen saturation, end-tidal CO(2) values and minimum alveolar concentration of agents were recorded. The percentages of the lymphocytes and their activation molecules were determined by flow cytometry in BAL samples. Results: The percentages of active cytotoxic T-cells (CD8(+)CD25(+).) and active B cells (CD19(+) HLA-D12(+)) decreased after desflurane anesthesia. The percentage of cytotoxic T-cells decreased after propofol anesthesia. The anesthesia with sevoflurane had no effect on the percentages and the activation molecules of the lymphocytes in the BAL fluid. Conclusion: This study showed that desflurane and propofol decreased either the percentages of the cell surface markers or the activation molecules of the lymphocytes during perioperative period in a tissue sample whereas the sevoflurane had no effect on these parameters. We conclude that sevoflurane has no effect on the lymphocytes in the BAL sample.en10.5336/medsci.2008-9364info:eu-repo/semantics/openAccessBronchoalveolar lavage fluiddesfluranesevofluranepropofolflow cytometryArticle312443449Q4WOS:000291330700025Q4
