[Influence of thromboelastography-guided hemostatic algorithm on allogeneic transfusion requirements during pediatric...

Area of Science:

• Anesthesiology
• Hematology
• Pediatric Surgery

Context:

• Pediatric hemispherectomy is a complex neurosurgical procedure associated with significant blood loss and transfusion requirements.
• Optimizing hemostasis during such surgeries is crucial for patient safety and outcomes.
• Thromboelastography (TEG) offers real-time assessment of coagulation status, guiding hemostatic interventions.

Purpose:

• To investigate the efficacy of a thromboelastography-guided hemostatic algorithm in reducing allogeneic blood product transfusion during pediatric hemispherectomy.
• To compare transfusion rates (RBC, plasma, platelets), blood loss, and postoperative complications between patients managed with and without TEG guidance.

Summary:

• A retrospective study of 38 pediatric hemispherectomy patients compared a TEG-guided group (n=17) with a control group (n=21).
• The TEG group showed significantly lower intra- and perioperative allogeneic plasma transfusion rates (52.9% and 64.7% vs. 90.5% and 95.2%, respectively; P<0.05).
• Fibrinogen concentrate use was higher in the TEG group (58.8% vs. 4.8%; P=0.001), while RBC transfusion rates, blood loss, seizures, and hospital stay did not differ significantly.

Impact:

• Thromboelastography-guided hemostasis effectively reduces the need for allogeneic plasma transfusions in pediatric hemispherectomy.
• This approach may optimize the use of specific blood products, such as plasma and fibrinogen concentrates.
• Further research can explore cost-effectiveness and broader application in pediatric neurosurgery.
