Clinical Trial Summary

REDuCe is designed to evaluate the role of ROTEM™ in determining the need and the amount of pre-emptive blood products use in patients with cirrhosis undergoing elective procedures compared to the current standard of care. The secondary aim of this study is to evaluate ROTEM™ parameters in patients with acute decompensation, acute on chronic liver failure and acute liver failure and to co-relate it with the conventional coagulation tests.

Description:

Patients with cirrhosis who meets eligibility criteria will be divided into two groups 1. Those who are undergoing elective procedures will be randomized into 1:1 ratio into either standard of care (institutional transfusion protocol) or ROTEM guided protocol. Baseline ROTEM will be obtained before and after blood product transfusion. 2. Those who are not for elective procedures and does not meet criteria for randomization will be entered into data collection for secondary endpoints analysis. These patients will have baseline ROTEM before transfusion and post transfusion ROTEM in those who require blood prodducts transfusion.

Intervention

Diagnostic Test:
• ROTEM
ROTEM is a commercially available whole blood Viscoelastic-Haemostatic Assay(VHA) point-of-care, global and dynamic haemostasis assessment tests that measures the viscoelastic changes occurring during the haemostatic process. They provide real-time, comprehensive reflection of the interaction between plasma, blood cells and platelets. It display hypo or hyper-coagulable features in patients with cirrhosis. It is widely used prior to cardiac, obstetric, trauma and liver transplant surgery to assess and correct for coagulation defects.
