The several factors which precipitate blood transfusion in hospitals are called “transfusion trigger”. The goal of perioperative blood replacement is to maintain satisfactory levels of haemoglobin and blood volume in order to have a better tissue oxygenation. The coagulation factors are used in the coagulations dysfunctions. The ideal is to avoid or to carry out a better blood transfusion in small quantities at a lower risk. Recent reports question the standards previously considered acceptable for blood transfusion. Blood substitute products for the treatment of haemorrhagic shock, blood bioproducts, and the indications for transfusions based on laboratory and clinical parameters, are analysed and discussed in this review.
