Rational approach to transfusion in liver transplantation

Area of Science:

• Hepatology
• Hematology
• Anesthesiology

Background:

• Liver cirrhosis was long associated with high bleeding risk, based on standard lab tests (SLTs).
• Recent evidence shows SLTs are poor predictors; stable cirrhosis patients have rebalanced hemostasis.
• Viscoelastic tests (VETs) dynamically assess coagulation, unlike static SLTs.

Purpose of the Study:

• To re-evaluate bleeding risk assessment in liver cirrhosis.
• To highlight the benefits of viscoelastic tests (VETs) in managing these patients.
• To discuss the paradigm shift in perioperative care for liver cirrhosis.

Main Methods:

• Review of recent publications challenging traditional views on cirrhosis-associated coagulopathy.
• Comparison of standard laboratory tests (SLTs) with viscoelastic tests (VETs) for bleeding prediction.
• Analysis of perioperative management strategies, including VET-guided hemostasis.

Main Results:

• Standard lab tests (SLTs) are unreliable for predicting bleeding in liver cirrhosis.
• Viscoelastic tests (VETs) provide a more accurate dynamic assessment of hemostasis.
• VETs have a proven track record in liver transplantation, reducing transfusion needs.

Conclusions:

• Bleeding in cirrhosis is often linked to mechanical factors like portal hypertension, not just coagulopathy.
• Perioperative management is shifting from SLT-based interventions to VET-guided strategies.
• Refined hemostatic management with VETs and reduced portal pressure improves outcomes.
