Justifications: Perioperative allogeneic blood transfusion can be reduced or even completely avoided by using a set of different strategies: meticulous hemostasis, the use of pharmaceutical agents that assist in the process of coagulation/ fibrinolysis, the use of blood substitutes, induced hypotension, preoperative autologous blood donation, collection and reinfusion of autologous blood during...
Despite advances in this field, allogeneic blood transfusion still carries a lot of risk; the availability of heterologous blood is also constantly decreasing. We describe the most popular methods for reducing the allogeneic blood requirement. Basic information is presented about the physiological mechanisms of compensation for intraoperative blood loss, which can be compromised by respiratory ...
Objective: To provide broad guidelines and principles to help physicians, other health care workers and patients make decisions about the appropriateness of red blood cell and plasma transfusion. Options: These guidelines are limited to red blood cell and plasma transfusion in adults and children over 4 months of age. Indications for specific clinical conditions and specialized blood components...
BACKGROUND Major blood loss usually occurs in both hip and knee arthroplasty, frequently leading to the need for blood transfusion. This study was performed to determine blood transfusion rates and analyze the factors which affected the need for blood transfusion in patients who underwent primary unilateral total knee and hip arthroplasties at the University Hospital of the West Indies, Jamaica...
RATIONALE Transfusion of erythrocytes stored for prolonged periods is associated with increased mortality. Erythrocytes undergo hemolysis during storage and after transfusion. Plasma hemoglobin scavenges endogenous nitric oxide leading to systemic and pulmonary vasoconstriction. OBJECTIVES We hypothesized that transfusion of autologous blood stored for 40 days would increase the pulmonary art...
Autologous transfusion has been used to overcome adverse effects of homologous transfusion. Clinical studies evaluating general orthopaedic postoperative results have been designed to compare these transfusion methods. However, few studies have evaluated postoperative results in spinal fusion surgeries, which have larger blood loss volumes. The purpose of this study is to determine if there are...
