1 gm
How much increase of hematocrit level per 1 unit pf prbc?
A good rule of thumb is 1 Unit of PRBCs will raise an adult's Hgb by 1 g/dl or their Hct by 2~3%. For pediatrics, a 10 ml/kg transfusion will increase Hgb by 3 g/dl and Hct by 10% These are approximations, of course, and depend on the size of the patient, the exact Hct of the transfused blood, and red blood cell survival after transfusion. In general, a unit of PRBCs is ~300 ml and has a Hct of 70% Ref: "Clinical Anesthesiology," E. Morgan, M. Mikhail, M. Murray. 4th ed.

What is a normal hematocrit for a 1 year old?
Hematocrit blood test shows the percentage of red blood cells (RBC's) in the blood. The test results vary from lab to lab (as all blood tests do). Hematocrit test results can also be 7% between different testing methods.The general range of normal by age:Newborns: 55%-68%One (1) week of age: 47%-65%One (1) month of age: 37%-49%Three (3) months of age: 30%-36%One (1) year of age: 29%-41%Ten (10) years of age: 36%-40%Adult males: 42%-54%Adult women: 38%-46%Adult pregnant women: about 30% - 34% lower limits and 46% upper limitsHigh Altitude residents: about 45% - 61% in males; 41% - 56% in females
