AIM: To investigate the effects of sevoflurane inhalation anesthesia only and propofol total intravenous anesthesia on perioperative cytokine balance in lung cancer patients. METHODS: ASA I or II patients undergoing lobectomy for lung cancer were randomly divided into two groups with 45 cases each. In group A, patients received g sevoflurane inhalation anesthesia only and patients in group B received propofol total intravenous anesthesia. The cervical venous blood samples were obtained at the following time points: before induetion of anesthesia(T0), before the start of one-lung ventilation(T1), before the end of one-lung ventilation(T2), after closed chest surgery(T3), after 24 h (T4) . The serum concentrations of IL-6, IL-8 and IL-10 were measured by ELISA. RESULTS: (1) In both groups the concentration of IL-6 increased at T1 and kept raising to a high level at T4 which showed significant differences with that of pre-operation(P < 0.05).Compared between the groups, the concentration of IL-6 at T1 and T2 in group B was lower than that of group A(P < 0.05). (2) In both groups the concentration of IL-8 kept at T1 and T3 which were significant with that of pre-operation(P < 0.01). The concentration of IL-8 decreased apparantly at T4 in both groups, it was significant with that of pre-operation though(P < 0.01).Compared between the groups, the concentration of IL-8 at T1, T2 and T3 in group B were all lower than that of group A (P < 0.05). (3) In both groups the concentration of IL-10 increased at T1 which was significant with that of pre-operation(P < 0.05)and kept at T2 and T3. It dropped somehow at T4 but still maintained at a high level.Compared between the groups, the concentration of IL-10 in group B at T1, T2, T3 and T4 was singicantly higher than that of group A(P < 0.05). CONCLUSION: Propofol causes less inflammatory mediator release and can also modulate the balance of cytokines. It is a better anesthetic for lung cancer than sevoflurane.
