storage lesion

Transfusion medicine The constellation of changes occurring in a unit of packed red cells during storage. See Red cell preservatives. Storage lesions ↑ Ammonium to 470 µmol/L–US: 800 µg/dL ↑ Free Hb in plasma from 82 to 6580 mg/L–US: 8.2 to 658 mg/dL ↑ K⁺ from 4.2 to 78.5 mmol/L–US: 4.2 to 78.5 mEq/L ↓ ATP from 100% to 45% ↓ 2,3 DPG to < 10% of original levels–replenished within 24 hours of transfusion ↓ Labile proteins, eg complement, fibronectin and coagulation factors ↓ to negligible ↓ Na⁺ from 169 to 111 mmol/L–US: 169 to 111 mEq/L ↓ pH from 7.6 to 6.7 Adverse physiologic effects of stored blood is negligible in the absence of a previous compromise of the Pt's–recipient's status
