| Summary: | <p>Pelvic fracture is the second most common cause of death in trauma patients after head trauma; and the major reason for death in these patients is hemorrhage and its resulting hypovolemic shock. Rapid and proper diagnosis and treatment can improve the outcome of these patients. The main treatment consists of fixation of the pelvis and resuscitation of patient’s hemodynamic using isotonic liquids and blood products until the condition is favorable for surgery or angiography. New findings show that fibrinogen plays a vital role in reaching and maintaining homeostasis, especially in patients that have lost a significant amount of blood. It seems that concentration of plasma fibrinogen, which is a key glycoprotein in the coagulation cascade, is independently related to hemorrhage and prophylaxis infusion of fibrinogen concentrate can decrease bleeding. Fibrinogen level has been introduced as a determining factor in prediction of 28-day mortality of patients with heavy traumatic bleeding. Compared to fresh frozen plasma (FFP), injection of fibrinogen concentrate has had better results in improvement of outcome and has decreased need for other blood components and has led to an increased probability of survival without increasing the risk of venous thromboembolism. A study in 2015 showed that 19.2% of the patients with severe hemorrhage due to trauma had a fibrinogen level less than 2gr/L.</p>Writers of the current letter evaluated 60 patients with traumatic pelvic fracture with the mean age of 51.12 ± 20.30 years (11-85) (58.30% male). 42 (70.0%) cases had presented with 1-sided or double sided ramus fracture, 17 (28.3%) cases with iliac wing fracture and 1 (1.7%) case with acetabulum fracture. 16.7% of the patients had a hemoglobin level less than 10 mg/dL and 21.7% had systolic blood pressure less than 90 mmHg on admission to emergency department. Mean blood level of fibrinogen in this group of patients was 261.85 ± 40.24 mg/dL (200-368). In other words, considering the normal range described for the kit used for this study (Mahsa Yaran Company, Iran) none of the patients were in the hypofibrinogenemia zone (< 200 mg/dL). It seems that variables such as trauma severity, racial characteristics, underlying illnesses, hemorrhage severity, type of fracture, and … might also affect the level of plasma fibrinogen and its decrease following hemorrhage. Overall, a final decision regarding the effect of fibrinogen injection instead of products such as FFP requires further studies with higher accuracy and considering other factors affecting the outcome of such patients. However, considering the studies that affirm the role of fibrinogen in improving the outcome of patients with severe hemorrhage, it seems that measuring plasma fibrinogen level and injecting it for patients with hypofibrinogenemia is a wise solution in management of this type of patients.
