Efficacy of red blood cell transfusion in the critically ill: A systematic review of the literature
Marik PE and Corwin HL.
Crit Care Med 2008; 36:2667–2674
COMMENTS: This systematic review shows that in at least 42 of the 45 reviewed clinical trials, involving 272.596 patients, the risk associated to
blood transfusion does not overcome the benefit proposed by the physicians. In two studies the result was neutral. The article has demonstrated that blood transfusions are associated with increased mortality and morbidity risk, and therefore, current transfusional practice should be reevaluated. Authors conclude that the risks and benefits of transfusion should be assessed in every patient before transfusion.
Effect of blood transfusion on long-term survival after cardiac operation
Engoren MC, Habib RH, Zacharias A et al.
Ann Thorac Surg. 2002;74:1180-6.
COMMENTS: This clinical trial has demonstrated that allogeneic blood transfusion (donated blood) is associated with an increase of up to 70%
on mortality, even after correction for comorbidities and other risk factors. According to authors, the blood transfusion by itself can cause death in patients.
Impact on early and late mortality after blood transfusion in coronary artery bypass graft surgery
Antonio Alceu dos Santos, Sousa AG, Thomé HOS, Machado RL and Piotto RF.
Rev Bras Cir Cardiovasc 2013;28(1):1-9.
COMMENTS: Authors demonstrated that red blood cells transfusion was an independent predictor factor of death after Coronary Artery Bypass
Grafting in a population of 1,888 patients. Even in a subgroup of low-risk patients (age <60 years and EuroSCORE ≤ 2%), there were significantly more deaths in the group that received allogeneic blood (someone else’s blood). Authors finalize the article saying that “new therapeutic options and autologous blood management and conservation strategies should be encouraged for reducing blood transfusions..
Transfusion of 1 and 2 Units of Red Blood Cells Is Associated With Increased Morbidity and Mortality
Paone G, Likosky DS, Brewer R, Theurer PF, Bell GF et all.
Ann Thorac Surg 2014;97:87–94.
COMMENTS: This article makes it clear that transfusion of as little as 1 or 2 units of RBCs, which is very common in surgeries, is significantly associated with increased patients mortality and morbidity (post-surgery complications). The authors conclude by suggesting aggressive practices of patient’s own blood conservation. They also state that even small amounts should be avoided in Coronary Artery Bypass Grafting.
Mortality risk is dose-dependent on the number of packed red blood cell transfused after coronary artery bypass graft
Antonio Alceu Santos, Sousa AG, Piotto RF, Pedroso JCM.
Rev Bras Cir Cardiovasc 2013;28(4):509-17.
COMMENTS: The authors investigated the effect of transfusion of 1, 2, 3, 4, 5 and ≥6 allogeneic blood bags (donated blood) in the risk of death in a population of nearly 2,000 patients. They demonstrated that increasing transfusions of packed red blood cell units result in increased risk of mortality, thereby showing a dose-response relationship. The conclusion was that the greater the amount of allogeneic blood transfused the greater the risk of mortality for the patients. They finalize the article by suggesting that the current transfusion practice needs to be reevaluated.

Oxygen carriers free of cells in transfusion medicine
Rev Bras Hematol Hemoterapia. 2007; 29(4):394 – 405.
COMMENTS: This article draws attention to demand for blood transfusion that is increasingly growing worldwide. It was found that in Brazil while blood demand grows at a rate of 1% per year, the expectations for growing of blood donations vary from 0.5 to 0.7% per year. Consequently, the estimate for the year 2030 will be a deficit of approximately 1,000,000 (one million) of collected blood units, has concluded the researching.

Senay S, Toraman F, Karabulut H, Alhan C.
Perfusion. 2009;24(6):373 – 80.
COMMENTS: This article shows that a hospital in California (USA), by simply remind the doctors the current guidelines regarding the use of allogeneic blood (donated) it reduced by 24% (about one quarter) blood transfusions and thereby saved US $ 1.6 million per year, it also reduced the average of patients’ length of stay in hospital from 10.1 to 6.2 days. But the main achievement of this attitude was to save lives, because mortality among people who received blood transfusions fell from 5.5% to Is it the patient or the physician who cannot tolerate anemia? A prospective analysis in 1854 non-transfused coronary artery surgery patients.

COMMENTS: The authors describe the fundamental role of the PRACTITIONER (cardiologist), the ANESTHESIOLOGIST, the SURGEON and the INTENSIVE CARE doctor for the success of two serious surgeries without using allogenic blood (donated). First case: ACUTE DISSECTION OF THE ASCENDENT THORACIC AORTA (69mm diameter) and important
AORTIC VALVAR INSUFICIENCY. Second case: CORONARIAN ARTHERY DISEASE, important AORTIC STENOSIS (average gradient of 55mmHg), important MITRAL STENOSIS (valvar area 1.0 cm²), besides anemia and THROMBOCYTOPENIA (61 thousand/mm³). They conclude by saying that it is possible to perform large surgeries with high risk of bleeding without using donated blood (homologous).

Reducing the Amount of Blood Transfused: A Systematic Review of Behavioral Interventions to Change Physicians’ Transfusion Practices
Tinmouth A, MacDougall L, Fergusson D, Amin M, Graham ID et al.
Arch Intern Med. 2005;165(8):845-852.
COMMENTS: Through this systematic review, authors have concluded that is possible to reduce the amount of blood and blood components transfusion in each patient, and thereby change the transfusional practice. The first step for this approach is the simple desire to change a transfusional behavior for a non-transfusional behavior.
Activity-based costs of blood transfusions in surgical patients at four hospitals
Shander A, Hofmann A, Ozawa S, Theusinger OM, Gombotz H, Spahn DR
COMMENTS: Authors have demonstrated that allogeneic blood (donated blood) to be transfused is expensive. It was found that the cost of a single bag of blood in the USA may reach US $ 1,200 (One Thousand and Two Hundred Dollars) when considered all the activities involved in the blood transfusion.
