Global Blood Transfusion Practices for Abdominal Injuries Mapped, Revealing Significant Variations
A new international study, published in The Lancet eClinicalMedicine and led by the University of Cambridge, has mapped global blood transfusion practices for life-threatening abdominal injuries. The research identifies significant variations in care worldwide. Part of the GOAL-Trauma study, it analyzed data from 1,768 patients across 187 hospitals in 51 countries. This marks the first multicentre international study to report on blood transfusion strategies for emergency abdominal surgery following trauma (trauma laparotomy).
Uncontrolled bleeding is a primary cause of death after abdominal trauma, making optimal blood transfusion essential. The study observed notable differences in how blood is administered across various resource settings.
Divergent Transfusion Strategies
Hospitals in higher-resource settings frequently utilized component therapy, which involves separating donated blood into packed red blood cells, plasma, and platelets. In contrast:
Whole blood transfusion, where blood is used without separation, was more than twice as prevalent in lower-resource settings.
Researchers suggested that the practical experience accumulated by clinicians in lower-resource settings regarding organizing donations and delivering whole blood transfusions in emergencies could inform practices in high-income trauma systems.
Dr. Joachim Amoako from the University of Ghana stated that whole blood has long been a routine part of trauma resuscitation due to its simpler storage and quicker delivery.
The Underutilized Lifesaver: Tranexamic Acid
The study also identified a low global adoption rate for tranexamic acid (TXA). This inexpensive medication is proven to reduce fatalities from traumatic bleeding when administered early.
Despite its recommendation as an essential medicine by the World Health Organization, TXA was used in less than 30% of cases globally.
Professor Timothy Hardcastle of the University of KwaZulu-Natal, South Africa, highlighted its benefits:
"TXA is affordable, widely available, and has strong evidence supporting its effectiveness in reducing trauma-related deaths."
He noted its routine use in obstetric hemorrhage and its availability even in lower-resource settings.
Crucial for Future Care
The researchers concluded that understanding these global variations is crucial for developing context-appropriate transfusion guidelines and designing future international studies. Further investigation into the role of whole blood is considered essential to ensure effective early care for trauma patients, irrespective of their location.
