👉 The fist fluid, also known as the pre-fluid or pre-hemorrhagic fluid, is a type of blood that accumulates in the interstitial spaces before significant blood loss occurs. It is characterized by its low protein content and high cellularity, primarily consisting of red blood cells, platelets, and some white blood cells. This fluid results from the disruption of the vascular endothelium due to trauma, leading to increased capillary permeability and the leakage of plasma components into the surrounding tissues. The presence of this fluid is an early indicator of severe blood loss and can help clinicians assess the severity of hemorrhage and guide immediate medical interventions.
