Changes of caprine (Capra hircus) blood during prolong storage for transfusion

Abstract

Background: This experiment was performed to investigate the effects of acid citrate dextrose (ACD) and citrate phosphate dextrose adenine-1 (CPDA-1) on the keeping qualities of various haematological and biochemical parameters of caprine blood during long time preservation and storage for transfusion. Methods: Sixteen healthy goats were selected and divided into 2 equal groups (A, n=8 and B, n=8). Fifty ml of blood was collected from each goat and preserved with ACD for group A (n=8) and CPDA-1 for group B (n=8). All the samples were stored at 40C in refrigerator for 28 days. The recorded blood parameters include total erythrocyte count (TEC), total leucocyte count (TLC), haemoglobin (Hb), packed cell volume (PCV), total protein (TP) and pH. The blood parameters were analyzed immediately after collection and thereafter on day-1, day-3, day-7, day-14, day-21 and day-28 for both the groups. Results: In both groups, the TEC, TLC, Hb and PCV values were decreased gradually from day-1 onward. In ACD preserved blood, the control values of TEC (11.27±0.26 million/cumm), TLC (8.85±0.22 thousand/cumm), Hb (8.61±0.13 g/dl) and PCV (30.75±0.59%) were decreased to TEC (9.21±0.38 million/cumm), TLC (7.58±0.10 thousand/cumm), Hb (7.03±0.06 g/dl) and PCV (22.25±0.53%) respectively on day-7 which was statistically significant (p‹0.05). However, the gradual decrease in the parameters was also noticed from day-7 onward. On the other hand, in case of CPDA-1 preserved blood, the control values of TEC (11.88±0.28 million/cumm), TLC (8.91±0.26 thousand/cumm), Hb (8.91±0.42 g/dl) and PCV (32.13±0.79%) were found decreasing slightly with the progression of the preservation period, but the changes were statistically significant (p‹0.05) on day-21 [TEC (8.06±0.22 million/cumm), TLC (6.28±0.34 thousand/cumm), Hb (6.28±0.16 g/dl) and PCV (25.02±0.46%) respectively] and onward. Changes in the TP and pH values were also noticed in both the groups during the experiment but CPDA-1 group showed less alteration than ACD group as compared to the control values. Conclusion: The results of this study revealed that CPDA-1 can be used for storing caprine blood longer period for transfusion in comparison to ACD with greater RBC viability.
