The James Blundell Award Lecture 2006: transfusion and the treatment of haemorrhage: past, present and future.
In the early years of the 19th century, James Blundell reported in the Lancet the first clinical application of blood transfusion for the treatment of haemorrhage. Although these initial experiments may appear to us to have burst upon the medical world, Blundell had in fact done a decade of pre clinical research using animal models to establish principles to be brought to the clinic. His pivotal pre clinical experiments and the insights he gained are described in detail. Today, blood transfusion remains the cornerstone of treatment for serious bleeding - not only to restore oxygen carrying capacity but also to improve haemostasis, arrest and prevent bleeding. However, the indications for the use of blood components to treat bleeding remain ill-defined. In particular, despite the enormous volumes of fresh frozen plasma (FFP) transfused worldwide, the evidence that commonly used coagulation tests are reliable guides to transfusion with FFP is scant. Recent laboratory and clinical studies provide insight into the weaknesses of current coagulation tests as a guide to blood management. In the future, the application of genomics to haemostasis will uncover genetic polymorphisms leading to improved diagnostics and more tailored medical therapeutics. Examples of the emerging use of clinical genomics are presented. Ultimately, the application of widescale genomics testing will refresh our understanding of human physiology and will reassert the importance of the individual in patient care.
