Abstract

Anemia is a common clinical problem in ICU. Almost universal by the end of first week after admission (1).How ever these result can be misleading because it is based on Hemoglobin concentration in blood as marker of Anemia. In ICU in critical illness it is a distinct entity although it is similar in many aspect to the anemia of chronic diseases, inflammation appears to be a measure factor. There are 3 major categories of anemia 1- Hypoproleferative anemia secondary to marrow production defects.2- In effective erythropoiesis caused by red cells maturation defects.3-Decreased servival of red blood cells. Secondary to blood loss, Hemolysis. Majority of anemia cases in ICU(75%) are hypoproliferative type. This article presents the current knowledge on defining various parameters of   anemia in ICU, etiopathogenesis its relation to tissue oxygenation and overall highlights the common practice of transfusing red blood cells to correct anaemia which is an arbitrary intervension in critical care medicine
