摘　　要：目的:探讨星状神经节阻滞(SGB)对内毒素血症小鼠血清炎性细胞因子及死亡率的影响,明确SGB可否成为系统性炎性反应综合征(SIRS)简单有效的辅助治疗手段。方法:内毒素血症小鼠分为SGB治疗组(颈部注射利多卡因)及对照组(颈部注射生理盐水),观察两组动物腹腔注射脂多糖(LPS)后2、7、14d血清TNF-α、IL-1β、IL-6的变化及2、4、7、10、15、20d累积死亡率的变化。结果:SGB治疗使内毒素血症小鼠2、7、14d的血清炎性细胞因子TNF-α、IL-1β、IL-6水平显著下降;注射LPS后2、4、7、10、15、20d的死亡率显著降低。结论:SGB可抑制内毒素血症小鼠过度的炎性反应,降低内毒素血症小鼠的死亡率,从而成为有益于SIRS治疗的简单有效的新手段。Objective To determine the feasibility of stellate ganglian block （SGB） therapy for the treatment of mice with endotoxemia. Methods Kun ming mice injected with 2 mg/kg Lipopolysaccharide （LPS） intraperitonealy were divided into control group （untreated by SGB） and SGB group （treated daily by SGB）. The roles of SGB were evaluated by comparing mortality and serum TNF-α,IL-1β,IL-6 levels in each group. Results Compared with control group, Mortality in SGB group decreased significantly at 2, 4, 7, 10, 15, 20 d after injecting LPS intraperitonealy. SerumTNF-α,IL-1β,IL-6levels decresed obviously in SGB group than that in control group. Conclusions These results indicate that SGB is a effective central therapeutic approach for treatment of endotoxemia. SGB can regulate systemic infammatory responses, which maybe mechanisms for effectiveness of SGB on mortality in mice with endotoxemia.
