How Many Patients Suffering Major Trauma Would be Eligible for a Pre-hospital Transfusion

Официальное название

How Many Patients Suffering Major Trauma Would be Eligible for a Pre-hospital Transfusion: A Multicentre Retrospective Study.

Обзор

The aim of the study is to measure the number of patients being cared for by a medical team for major trauma who could benefit from a transfusion labile blood products and thus provide a scientific argument in favour of supplying labile blood products to pre-hospital

Подробное описание

In France, pre-hospital resuscitation of major trauma patients does not use labile blood products, except in exceptional circumstances. The physician staffed Mobile Intensive Care Unit (MICU) are not equipped with this type of product. The first cause of death compatible with survival in the event of pre-hospital treatment identified in major trauma in war medicine is exsanguination. Mortality in haemorrhagic shock occurs rapidly and appears to be significantly reduced if transfusions are performed early. Early transfusion has proved its worth in the military context, leading the armed forces health service to recommend transfusion as a first-line treatment as quickly as possible, from the moment the patient is taken into care on the battlefield. More recently, in the North American civilian pre-hospital setting, the PAMPer study included 501 patients, 230 of whom were transfused with fresh frozen plasma (FFP - 2 units). The authors reported a significant reduction in mortality at D+30 in the FFP group (23.2% vs 33%; p=0.03). It therefore seems that transfusion as early as possible is associated with a reduction in mortality in the context of major trauma.

The aim of the study is to measure the number of patients being cared for by a medical team for major trauma who could benefit from a transfusion labile blood products and thus provide a scientific argument in favour of supplying labile blood products to pre-hospital.
