Abstract:
Objective To clarify the effects of sedation with propofol on pro/anti-inflammatory cytokines balance in severe sepsis patients resulted from intra-abdominal infection.Methods Fifteen patients with severe sepsis were randomly divided into two groups,propofol group received intravenous propofol sedation more than 48 hours,and no sedation drug were used in control group,3 volunteers as healthy group.Plasma TNF-?,IL-10 concentrations were measured at admission and 48 hours later,the ratio of TNF-?/IL-10 (T/I) were also calculated.Results Levels of both TNF-?,IL- 10 were significantly elevated in patients compared with healthy group,but no difference between prepofol and control group.The mean load doses of propofol was 0.063 mg/kg and maintained at 0.054 mg/(kg?h).After 48 hours infusion of prepofol,TNF-?,IL-10 decreased significantly compared with admission in propofol group,while no changed in control group.Compared with control group,IL-10 was lower and ratio of T/I was higher in propofol group.Conclusion Sedation with prepofol in severe sepsis patients attenuated the pro-and anti-inflammatory cytokine responses.Moreover, propofol accelerate the shift to Th1.These findings suggest that the influence of sedation drug on immune function must be considered in sepsis patients.
