Clinical outcomes of observational studies of autologous versus allogeneic blood transfusions
Table A Effects of different techniques of autologous transfusion
Positive | |||
Minimises transfusion transmitted disease | |||
Minimises red cell alloimmunisation | |||
Provides compatible blood for patients with alloantibodies or rare red cell phenotypes | |||
Reduces incidence of febrile or allergic reactions | |||
Reduces risk of ABO incompatibility | |||
Reduces risk of postoperative infection or cancer recurrence | |||
Reduces risk of bacterial contamination | |||
Reduces risk of volume overload | |||
Autologous donation process risk free | |||
Almost all patients eligible | |||
Lends itself to both elective and non-elective surgery | |||
Need for allogeneic blood eliminated | |||
Reduces allogeneic blood exposure | |||
Haemostatic potential of transfused blood remains intact | |||
Supplements allogeneic blood supply | |||
May be used in patients with systemic infection | |||
Less costly than allogeneic transfusion | |||
Negative | |||
Subjects patients to anaemia | |||
Inconvenient for patients | |||
