Abstract:
Transfusion of Packed RBC units (PRBC) in multi-transfused patients often results in a progressive rise in transfusion requirements. To evaluate the procoagulant potential of PRBC in multi-transfused patients. We conducted this prospective cohort study (2020-2022) on multi-transfused patients (n = 31) having a lifetime transfusion of ≧ 4 units PRBCs. Biochemical parameters pre-, post-transfusion (≤ 24 hours) samples included, highly sensitive C reactive protein (HsCRP) for inflammation, LDH for hemolysis, tissue plasminogen activator (tPA), Antithrombin 3 (ATIII) levels as coagulopathy, anti-hemostatic marker and blood microparticle (MPs) (flowcytometry) as Annexin 5+ (AV+) events for TF. We performed Wilcoxon signed rank test (P≤ 0.05), pre-, posttransfusion (P≤ 0.05) and association pre- and posttransfusion by Spearman's rho correlation coefficient (CC), Linear regression (r2). Median (95% CI; P≤ 0.05) biochemical parameters pre-, posttransfusion, tPA {7.88 (2.63-20.44); 14.40 (5.29-27.08)} (P = 0.012) and ATIII {1299.66 (1078.5-1362.5); 1358.92 (1216 -1384.3)} (P = 0.011) respectively. A pre-, posttransfusion comparison of HsCRP (P = 0.45); LDH (P = 0.87) and MPs (number of events) (P = 0.54) pre-, posttransfusion were not significantly different. We observed a significant CC pre-posttransfusion HsCRP (0.61, P < 0.01); ATIII (0.480, P = 0.006); tPA (0.807, P < 0.01); MPs (0.625, P < 0.004) and r2 tPA (posttransfusion) (dependent variable) tPA (pre-transfusion), ATIII (pre-transfusion) (predictor variables) r2 = 0.85 (P < 0.01); ATIII (posttransfusion) (dependent variable) and ATIII (pre-transfusion); LDH (pre-transfusion) (predictor variable) r2 = 0.45 (P = 0.026). A significant differences tPA, ATIII (pre-posttransfusion) and an association 'pre-posttransfusion' may be attributed to PRBC transfusions. tPA levels with corresponding changes in ATIII indicate coagulopathic response, following PRBC transfusions.

The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
