Massive hemorrhage significantly alters coagulation, decreasing fibrinogen (FIB), hemoglobin (HGB), hematocrit (HCT), and platelets (PLT) while increasing prothrombin time (PT) and activated partial thromboplastin time (APTT). FIB showed the strongest correlation with blood loss.
Area of Science:
- Hematology
- Trauma Surgery
- Critical Care Medicine
Background:
- Massive hemorrhage presents significant challenges in managing coagulation function.
- Understanding dynamic changes in hemostatic parameters is crucial for timely intervention.
Purpose of the Study:
- To investigate the alterations in coagulation function and component transfusion parameters during massive hemorrhage.
- To establish correlations between blood loss volume and specific hemostatic markers.
Main Methods:
- Sixty-two patients with massive hemorrhage were enrolled.
- Blood samples were collected at 1000, 1500, 1700, and 2000 ml blood loss.
- Measured parameters included Fibrinogen (FIB), Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT), Hemoglobin (HGB), Hematocrit (HCT), Platelets (PLT), and Mean Arterial Pressure (MAP).
Main Results:
- Significant decreases in FIB, MAP, HGB, HCT, and PLT were observed with increasing blood loss, falling below baseline values.
- PT and APTT significantly increased progressively with greater blood loss.
- FIB, HCT, and HGB dropped below normal ranges at 1500 ml blood loss, with PT and MAP exceeding normal ranges at 2000 ml.
- FIB demonstrated the strongest correlation with intraoperative blood loss.
Conclusions:
- Intraoperative massive blood loss leads to significant and progressive derangements in coagulation function.
- Fibrinogen levels show the most pronounced correlation with the extent of blood loss, highlighting its importance in monitoring and management.

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
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 forms a...
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, and...
Blood Transfusion and Agglutination
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...
