使用外源性糖类固醇,尤其是地塞美松治疗外伤性脑水肿被认为是有益的。许多实验研究证实了此点,但其他研究则否。一个问题是糖类固醇对脑功能的改善很难与其对脑水肿的良好作用相区别,似乎是糖类固醇改善脑功能,却未减低脑水肿的程度。另一个问题,在研究中糖类固醇几乎对于任何生化的,或生物学的系统都有效应。根据实验设计,这些糖类固醇既可产生有益的,亦可产生有害的作用。 The use of exogenous steroids, especially dexamethasone, for treating traumatic brain edema is considered beneficial. Many experimental studies confirm this point, but none of the other studies. One problem is that the improvement of brain function by steroids is difficult to distinguish from their good effect on brain edema. It seems that steroid improves brain function without decreasing the degree of cerebral edema. In another question, sugar steroids are almost effective in any biochemical, or biological, system in the study. According to the experimental design, these sugar steroids can produce beneficial and harmful effects.
