Massive hemorrhage and transfusion in the operating room

Area of Science:

• Anesthesiology
• Hematology
• Critical Care Medicine

Background:

• Massive hemorrhage presents significant clinical challenges, often with unpredictable onset.
• Factors like acidosis, hypothermia, and hypotension critically impact patient prognosis.
• Understanding the unique pathophysiology of obstetric hemorrhage is crucial.

Purpose of the Study:

• To review the pathophysiology and clinical features of massive hemorrhage.
• To discuss laboratory diagnostics and therapeutic interventions, including blood products and adjunct therapies.
• To examine the anesthesiologist's role in massive transfusion protocols.

Main Methods:

• Review of pathophysiology and clinical manifestations.
• Analysis of laboratory investigations and therapeutic measures.
• Exploration of blood/plasma products, adjunct therapies, and transfusion protocols.

Main Results:

• Timely laboratory results and point-of-care testing aid clinical decisions, but transfusion is ultimately a clinical judgment.
• Red blood cells are vital for oxygen transport and hemostasis.
• Adjunct therapies improve outcomes, and massive transfusion protocols enhance treatment delivery.

Conclusions:

• Effective massive hemorrhage management is a multidisciplinary effort requiring seamless communication.
• Inconsistent knowledge of available treatments necessitates standardized protocols.
• Massive transfusion protocols streamline response, ensuring timely and appropriate interventions.
