Serum potassium changes following packed red cell transfusions in newborn infants. 1983

D G Batton, and M J Maisels, and G Shulman

We studied the effect of packed red cell transfusions on serum potassium levels in sick newborn infants. In 11 transfusions the infants' serum potassium levels fell from a mean of 5.1 +/- 1.2 mEq per 1 (SD) to 4.9 +/- 1.2 mEq per 1 within 1 hour of the transfusion. Plasma potassium in stored packed red cells rose markedly within 48 hours of drawing. In spite of this, the transfusion of 10 ml per kg of packed red cells did not affect the serum potassium concentration in the newborn infant.

D007232	Infant, Newborn, Diseases	Diseases of newborn infants present at birth (congenital) or developing within the first month of birth. It does not include hereditary diseases not manifesting at birth or within the first 30 days of life nor does it include inborn errors of metabolism.

D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D001793	Blood Preservation	The process by which blood or its components are kept viable outside of the organism from which they are derived (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).

D001803	Blood Transfusion	The introduction of whole blood or blood component directly into the blood stream. (Dorland, 27th ed)	Blood Transfusions,Transfusion, Blood,Transfusions, Blood
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D006947	Hyperkalemia	Abnormally high potassium concentration in the blood, most often due to defective renal excretion. It is characterized clinically by electrocardiographic abnormalities (elevated T waves and depressed P waves, and eventually by atrial asystole). In severe cases, weakness and flaccid paralysis may occur. (Dorland, 27th ed)	Hyperpotassemia,Hyperkalemias,Hyperpotassemias
D017707	Erythrocyte Transfusion	The transfer of erythrocytes from a donor to a recipient or reinfusion to the donor.
