New Insights Challenge Traditional Approaches to INR and Thrombocytopenia Correction
In the evolving landscape of cirrhosis management, healthcare professionals are reevaluating the necessity of correcting elevated INR and thrombocytopenia before low-risk procedures like paracentesis. Recent studies and guidelines suggest that traditional coagulation markers may not be reliable indicators of bleeding risk in this patient population, calling for a more nuanced approach.

The findings here underscore the need for a more individualized approach to coagulation management before low-risk procedures. Traditional markers like INR and platelet count may not be the reliable indicators we once thought they were. Instead, a comprehensive clinical assessment, possibly supplemented by emerging technologies like VET, may offer a more accurate picture of bleeding risk.
- Elevated INR in cirrhosis patients does not predict postprocedural bleeding risk, and correcting it with fresh frozen plasma is not recommended.
- Thrombocytopenia, commonly seen in cirrhosis due to hypersplenism and decreased hepatic thrombopoietin production, does not consistently correlate with bleeding risk in low-risk procedures.
- Current guidelines advocate a conservative approach to prolonged INR, thrombocytopenia, and fibrinogen deficiency.
- Anemia, renal failure, and sepsis are known clinical predictors of bleeding in cirrhosis patients, unrelated to coagulation testing.
- Viscoelastic testing (VET), although promising, is not yet recommended for routine use in nonsurgical settings due to limited availability and specialized training requirements.
A meta-analysis of 29 studies found no significant association between preprocedural INR and periprocedural bleeding events in cirrhosis patients.
- Severe thrombocytopenia (platelet count less than 50 × 10^9/L) may warrant case-by-case consideration for platelet transfusion in high-risk procedures.
- Fibrinogen deficiency does not require routine correction; cryoprecipitate transfusion has not shown a reduction in bleeding.
- Ultrasonographic guidance can reduce bleeding complications in certain procedures.
