Background:
The benefit of a balanced resuscitation in low volume transfusions remains unclear This study is aimed at characterizing blood product ratios in this cohort.
Methods:
A retrospective analysis (2017-2019) of the ACS TQIP was performed to identify adult trauma patients who received ≥1 unit of packed red blood cells (pRBCs) 4 and 24 h after admission. Blood products received were used to calculate plasma and platelet ratios.
Results:
Plasma and platelet ratios were closer to the target 1:1 ratio for ≤4 units pRBCs. Plasma and platelet ratios increased for those receiving ≤10 units pRBCs, demonstrating increasingly unbalanced resuscitation. Transfusion ratios were unbalanced for those receiving ≥5 units pRBC.
Conclusion:
Transfusion ratios were closer to the desired transfusion ratio for low volume blood product resuscitation. In those receiving ≥5 units pRBC, plasma and platelet ratios were not balanced. The optimal transfusion ratio in low volume trauma resuscitation is unknown.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
Blood Transfusion
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...
Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
