Transfusing blood after prolonged storage could lead to:: (A) Citrate intoxication, (B) Potassium toxicity, (C) Circulatory overload, (D) Haemorrhagic diathesis
Answer is B. Prolonged storage of blood can lead to hyperkalemia due to lysis of RBC. Citrate intoxication, circulatory overload & haemorrhagic diathesis results from massive blood trasfusion. Citrate intoxication - Hypocalcemia, manifested by circumoral numbness and/or tingling sensation of the fingers and toes. Circulatory overload - Transfusion-associated circulatory overload (TACO). Dyspnea, bilateral infiltrates on CXR with systolic hypeension and elevated levels of Brain natriuretic peptide (BNP). Haemorrhagic diathesis - Dilutional thrombocytopenia
