A State-Wide Retrospective Cohort Study Examining Effects of Transfusing Old Blood Products in Vascular Surgical Patients.
Introduction: We investigated the effects of transfusing blood products close to the expiration date (i.e., ≥35 days packed red blood cells [PRBCs] and >3 days platelets [PLTs]) on vascular patients.
Methods: We retrospectively examined all PRBC and PLT transfusions in patients who underwent vascular procedures without cardiopulmonary bypass in Queensland from 2007 to 2013. Mortality, length of stay (LOS), and blood product quantities were compared in patients transfused exclusively with PRBCs <21 days vs. PRBCs ≥35 days and PLTs ≤3 days vs. PLTs >3 days.
Results: No significant mortality difference was found between patients transfused fresh vs. old PRBCs (26/493 [5.3%] vs. 6/152 [3.9%]; OR 0.75; 95% CI: 0.3-1.9). Patients transfused fresh PRBCs experienced a longer LOS (11 days [IQR: 7-20] vs. 10 days [IQR: 7-15]; 95% CI: -4.8 to -0.24) and more PRBC units (3.9 ± 4.5 units vs. 2.1 ± 1.3 units; 95% CI: -2.3 to -0.9). Among patients transfused PLTs, there were no significant differences in mortality (24/124 [19.4%] vs. 14/78 [17.9%]; OR 1.0; 95% CI: 0.5-2.3) between patients transfused fresh vs. old PLTs.
Conclusion: Within the limitations of the retrospective study design, transfusion of older PRBCs or PLTs was associated with fewer transfused units, shorter hospital stays, but no difference in mortality.
期刊介绍：
The ''Journal of Vascular Research'' publishes original articles and reviews of scientific excellence in vascular and microvascular biology, physiology and pathophysiology. The scope of the journal covers a broad spectrum of vascular and lymphatic research, including vascular structure, vascular function, haemodynamics, mechanics, cell signalling, intercellular communication, growth and differentiation. JVR''s ''Vascular Update'' series regularly presents state-of-the-art reviews on hot topics in vascular biology. Manuscript processing times are, consistent with stringent review, kept as short as possible due to electronic submission. All articles are published online first, ensuring rapid publication. The ''Journal of Vascular Research'' is the official journal of the European Society for Microcirculation. A biennial prize is awarded to the authors of the best paper published in the journal over the previous two years, thus encouraging young scientists working in the exciting field of vascular biology to publish their findings.
