Gram-negative bacteremia is an increasingly important nosocomial infectious problem. Endotoxin, endorphins, leukocyte agglutination and deficient opsonization all appear to be major factors in the pathogenesis of Gram-negative septic shock. Outcome has previously correlated best to underlying disease state. With appropriate double antibiotic therapy and hemodynamic support, however, mortality has decreased even for neutropenic patients. Corticosteroids, naloxone, granulocyte transfusions and immunotherapy are experimental adjunctive modes of therapy that offer hope for even better survival in the future.
革兰阴性菌血症是一个日益重要的医院感染问题。内毒素、内啡肽、白细胞凝集和调理素缺乏似乎都是革兰阴性菌败血症休克发病机制中的主要因素。此前,预后与基础疾病状态的相关性最强。然而,通过适当的双联抗生素治疗和血流动力学支持,即使是中性粒细胞减少的患者死亡率也有所下降。皮质类固醇、纳洛酮、粒细胞输注和免疫疗法是实验性辅助治疗方式,为未来更好的生存率带来了希望。
