Background and Objectives: Saline adenine glucose mannitol (SAGM) with citrate phosphate dextrose (CPD) or CPD adenine (CPDA) are two common red cell preservatives used in our country. This study analyzed and compared serial biochemical changes on different days of storage in irradiated packed red blood cells stored in CPDA and SAGM solutions. The aim of this study was to see if these changes are influenced by or different, if any, in these two storage solutions. Patients and Methods: Ninety units of RBCs were randomly chosen, with 45 units each collected in CPDA and SAGM, respectively. Nine units each were irradiated by gamma irradiator using cobalt 60 (BI 2000) on days 1, 7, 14, and 21 of their storage, respectively. Nine units were not irradiated and used as controls. All the units were weekly assessed for their plasma levels of potassium, sodium, glucose, lactate dehydrogenase (LDH), and lactate by Clinical Chemistry Auto-analyzer, Beckman Coulter AU680. The values were documented and analyzed by SPSS. Results: Baseline values on day 1 for potassium, lactate, and LDH were similar between SAGM- and CPDA-stored blood bags. Glucose and sodium levels were slightly higher in SAGM bags compared to CPDA. Postirradiation, the changes (increase in K+, Lactate, LDH and decrease in Na+, glucose) were higher in CPDA bags than SAGM bags, and the difference in this trend was not significantly different from that seen in nonirradiated blood bags stored in these two preservative solutions. Conclusion: Storage lesions (biochemical parameters) after irradiation were severe, but paralleled that observed in nonirradiated bags. The storage solution, either SAGM or CPDA, made no difference to these changes.
