文摘1 第三间隙效应——正平衡输液: 生理状态下,毛细血管和细胞膜上Na^+—K^+泵维持血浆、间质浓和细胞内液之间的动态平衡。而当机体受到感染性或非感染性损伤后,引发全身性炎症反应(Systemic inflammatory response,SIR),导致毛细血管内皮细胞损害、毛细血管通透性通知,结果不但在局部出现炎性渗出反应,而且在重症时全身毛细血管床都有渗出;透过6300m^2的毛细血管,大量血浆漏入间质液。如同时有组织低血流灌注和缺氧发生,Na^+—K^+泵活性下降,使间质液中钠水进入细胞内。此外,肝脏、肌肉和占体重6％的胶元组织等也摄取钠和水。这种细胞外液的大量移位就是所谓第三间隙效应(the third space effect)或液体扣押(Sequestration)。
