“…In the first article, they described a logistic regression model of the occurrence of postoperative pneumonia in a series of 416 consecutive CABG patients [43]. In their model, they observed an association between the length of storage of non-leucoreduced red blood cell units administered and the occurrence of pneumonia.…”

Current issues relating to the transfusion of stored red blood cells

The development of blood storage systems allowed donation and transfusion to be separated in time and space. This separation has permitted the regionalization of donor services with subsequent economies of scale and improvements in the quality and availability of blood products. However, the availability of storage raises the question of how long blood products can and should be stored and how long they are safe and effective. The efficacy of red blood cells was originally measured as the increment in haematocrit and safety began with typing and the effort to reduce the risk of bacterial contamination. Appreciation of a growing list of storage lesions of red blood cells has developed with our increasing understanding of red blood cell physiology and our experience with red blood cell transfusion. However, other than frank haemolysis, rare episodes of bacterial contamination and overgrowth, the reduction of oxygen-carrying capacity associated with the failure of some transfused cells to circulate, and the toxicity of lysophospholipids released from membrane breakdown, storage-induced lesions have not had obvious correlations with safety or efficacy. The safety of red blood cell storage has also been approached in retrospective epidemiologic studies of transfused patients, but the results are frequently biased by the fact that sicker patients are transfused more often and blood banks do not issue blood products in a random order. Several large prospective studies of the safety of stored red blood cells are planned.

“…In adults, transfusion is an independent predictor of death and is associated with an increased incidence of multiorgan system failure, length of hospital stay, infection risk, and modulation of the immune system (1,2). Although the mechanisms underlying these associations are yet to be comprehensively characterized, a two-hit model of posttransfusion injury has been proposed (3).…”

Plasma cytokines and markers of endothelial activation increase after packed red blood cell transfusion in the preterm infant

et al. 2012

Background: Transfusion of packed red blood cells (PRBcs) saves lives in the neonatal critical care setting and is one of the most common interventions in the preterm infant. The number and volume of PRBc transfusions are associated with several major neonatal morbidities, although a direct causal link between transfusion and major neonatal morbidity is still to be proven. Transfusion-related immunomodulation (TRIM) may underlie these adverse outcomes, yet it has received little attention in the high-risk preterm infant. Methods: One transfusion event was studied in infants ≤28 wk gestation between 2 and 6 wk postnatal age (n = 28). Plasma inflammatory cytokines and markers of endothelial activation were measured in the infants before and 2-4 h after transfusion, as well as in the donor pack. results: Median (range) age at transfusion was 18 (14-39) days with the pretransfusion hemoglobin level at 9.8 (7.4-10.2) g/dl. Interleukin (IL)-1β (P = 0.01), IL-8 (P = <0.001), tumor necrosis factor-α (P = 0.008), and monocyte chemoattractant protein (P = 0.01) were increased after transfusion. a similar elevation in markers of endothelial activation was seen after transfusion with increased plasma macrophage inhibitory factor (P = 0.005) and soluble intracellular adhesion molecule-1 (P = <0.001). conclusion: Production of inflammatory cytokines and immunoactivation of the endothelium observed after the transfusion of PRBcs in the preterm infant may be a manifestation of TRIM. The implications of this emerging phenomenon within the preterm neonatal population warrant further investigation. t ransfusion of blood products is not benign. In adults, transfusion is an independent predictor of death and is associated with an increased incidence of multiorgan system failure, length of hospital stay, infection risk, and modulation of the immune system (1,2). Although the mechanisms underlying these associations are yet to be comprehensively characterized, a two-hit model of posttransfusion injury has been proposed (3). In the clinical setting of an underlying inflammatory state priming the recipient's immune system, transfusion of packed red blood cells (PRBCs) may trigger immune cell activation and related immunomodulation, resulting in frank inflammation (4). This transfusion-related immunomodulation (TRIM), encompassing not only adverse proinflammatory and immunosuppressive responses but also the whole spectrum of posttransfusion effects on organs and tissues, has been proposed to underlie much of the increased transfusionassociated morbidity and mortality seen in adults (4).In the neonatal population, there is an increasing awareness of the excess morbidity and mortality associated with PRBC transfusions (5,6). PRBC transfusions have been implicated in the development of problems not encountered in the adult population, including chronic lung disease (7), retinopathy of prematurity (8), and necrotizing enterocolitis (9,10), with the incidence and severity of these conditions correlating with the number and volume of PRBC tran...

Is Allogeneic Blood Transfusion a Risk Factor for Sternal Dehiscence Following Cardiac Surgery? A Prospective Observational Study

et al. 2009

SummarySternal dehiscence following cardiac surgery has a multifactorial etiology. Significant risk factors contributing to sternal dehiscence include chronic obstructive pulmonary disease (COPD), obesity, or re-exploration due to bleeding or pericardial tamponade. We have focused on the role of allogeneic blood transfusion as a factor leading to the poor healing of surgical wounds.A prospective observational study of 1553 elective and emergency cardiac surgery patients was performed between January 2003 and June 2007. All of the patients enrolled in this study underwent median sternotomy. We studied the relationship between sternal dehiscence following cardiac surgery and the total number of packed red blood cells transfused.The incidence of sternal dehiscence in the study group was 3.4%. Diabetic patients did not have a higher incidence of wound dehiscence. Although COPD, 2) obesity, 2) and re-exploration 4) contributed to sternal dehiscence, the number of allogeneic blood transfusions during the perioperative period was an important independent risk factor for sternal dehiscence. Patients with sternal dehiscence received an average of 7.6 transfusion units (TU) of allogeneic blood versus 1.6 TU of allogeneic blood in the group without sternal dehiscence (P < 0.00005). The dehiscence affected patients without any other significant risk factor who received 6 or more TU, or patients with at least one significant risk factor who received 4 or more TU of allogeneic blood. According to our results, the total amount of allogeneic blood transfused is an important risk factor contributing to sternal dehiscence. Regardless of other risk preconditions, the transfusion of 6 or more TU could result in sternal dehiscence following cardiac surgery. (Int Heart J 2009; 50: 601-608)
