(2020-02-03)

Patients given less blood during transfusions do well
It's a simple premise -- now backed up by more evidence than ever: 'Why give more blood to anyone if you can't show it benefits them?' Jeffrey Carson of Rutgers Robert Wood Johnson Medical School has found that for many patients, smaller blood transfusions after surgery are at least as beneficial as larger ones, both in the short term and the long term. His study is published in The Lancet. (2014-12-10)

Antifibrinolytic drugs reduce blood loss during cardiac surgery
The amount of blood loss that occurs during major complex surgery is limited by the body's ability to form blood clots. This Cochrane Review concludes that drugs that slow down the rate at which these blood clots are dissolved, called antifibrinolytics, can significantly reduce blood loss, particularly during cardiac surgery, and reduce the need for reoperation because of continued bleeding. One of the effective drugs, tranexamic acid, is quite cheap and is likely to be cost effective, particularly in cardiac surgery. (2007-10-16)

Blood transfusions linked to increased mortality in patients suffering from cardiac episodes
The controversial practice of blood transfusions for patients suffering from cardiac episodes may lead to an increased risk of mortality, and may be correlated to transfusion blood type and blood age, according to research presented today at the American College of Cardiology Annual Scientific Session. ACC.06 is the premier cardiovascular medical meeting, bringing together more than 30,000 cardiologists to further breakthroughs in cardiovascular medicine. (2006-03-14)

Big transfusions add risk for heart attack patients with anemia
A new study published in the Archives of Internal Medicine finds that while blood transfusions for heart attack patients with anemia are commonly performed in emergency rooms, the practice can increase the risk of death when the transfusions are too extensive. The authors, led by Saurav Chatterjee, a cardiology fellow at Brown University, compared evidence from 10 prior studies of more than 203,000 patients. (2012-12-24)
