脑损伤后组织渗透压或脑脊液渗透压的变化在文献中很少受到关注，但渗透作用可能是早期脑水肿的重要原因。本文综述了渗透作用的相关概念和术语，并对文献中少数几篇研究脑损伤后渗透作用的文献进行了综述。在创伤性脑损伤和脑缺血的研究中，组织渗透压升高。脑脊液的渗透压也随着损伤的增加而增加。目前还没有检测脑损伤后组织或脑脊液渗透压的人体研究。讨论了渗透梯度的理论含义。
Changes in tissue osmolarity or cerebrospinal fluid osmolarity after cerebral injury have received little attention in the literature, but osmosis may be an important cause of early cerebral edema. This paper reviews concepts and terms relating to osmosis, and reviews the few papers in the literature which have studied osmolarity after cerebral injury. In studies of both traumatic brain injury and ischemia, tissue osmolarity is elevated. Osmolarity of cerebrospinal fluid has also been shown to increase with injury. There have been no human studies examining osmolarity of tissue or cerebrospinal fluid after cerebral injury. Theoretical implications of the osmotic gradient are discussed.
