In pelvis fracture, the amount of blood loss is around

D i.e. 4 - 8 units In pelvis fracture intrapelvic haemorrhage is by far, the most serious complication. Haemorrhage frequently results from fracture surfaces and small vessels in the retro peritoneum. Amount of blood loss is around 4 - 8 unitsQ. It must be emphasised, however, that these cases may need transfusion of very large quantities of blood. It is not uncommon for the amount of blood transfused to be in excess of the patients's total blood volume. In cases of hemodynamic instability, an external fixator should be applied immediately to decrease motion at fracture sites as well as to decrease pelvic volume and generate temponade of the pelvic venous plexus.
