Posttraumatic massive bleeding: a challenging multidisciplinary task

Consequences of Transfusing Blood Components in Patients With Trauma: A Conceptual Model

Transfusion of blood components is often required in resuscitation of patients with major trauma. Packed red blood cells and platelets break down and undergo chemical changes during storage (known as the storage lesion) that lead to an inflammatory response once the blood components are transfused to patients. Although some evidence supports a detrimental association between transfusion and a patient's outcome, the mechanisms connecting transfusion of stored components to outcomes remain unclear. The purpose of this review is to provide critical care nurses with a conceptual model to facilitate understanding of the relationship between the storage lesion and patients' outcomes after trauma; outcomes related to trauma, hemorrhage, and blood component transfusion are grouped according to those occurring in the short-term (≤30 days) and the long-term (>30 days). Complete understanding of these clinical implications is critical for practitioners in evaluating and treating patients given transfusions after traumatic injury.

Massive bleeding: Are we doing our best?

Massive bleeding accounts for more than 50% of all trauma-related deaths within the first 48h following hospital admission and it can significantly raise the mortality rate of any kind of surgery. Despite this great clinical relevance, evidence on the management of massive bleeding is surprisingly scarce, and its treatment is often based on empirical grounds. Successful treatment of massive haemorrhage depends on better understanding of the associated physiological changes as well as on good team work among the different specialists involved in the management of such a complex condition.
