Management of RT Suction Bleed with Thrombocytopenia and Elevated INR
For a patient with respiratory tract suction bleeding, platelet count of 40,000/μL and INR of 4.3, immediate transfusion of both platelets and fresh frozen plasma (FFP) is required to correct the coagulopathy and stop the bleeding.
Initial Assessment and Management
- Perform visual assessment of the bleeding site to determine severity and extent of blood loss 1
- Check suction canisters and respiratory equipment to quantify blood loss 1
- Monitor vital signs for signs of hemodynamic compromise 1
Platelet Transfusion
- Platelet transfusion is clearly indicated with a count of 40,000/μL in the presence of active bleeding 1
- Target a minimum platelet count of 75,000/μL as this is appropriate in the clinical situation of active bleeding 1
- Administer platelets even before laboratory confirmation in cases of ongoing bleeding 1
- Consider potential causes of thrombocytopenia (drug-induced, consumptive, dilutional) while initiating treatment 1
Fresh Frozen Plasma Administration
- FFP transfusion is strongly indicated with an INR of 4.3 (>2.0) in the presence of active bleeding 1
- Administer FFP at a dose of 10-15 mL/kg to achieve a minimum of 30% plasma factor concentration 1
- For INR >4.0, consider higher doses of FFP as standard regimens may be inadequate 1
- Monitor INR after transfusion to assess response and need for additional FFP 1
Alternative or Additional Interventions
- For warfarin-associated coagulopathy (if applicable), consider prothrombin complex concentrate (PCC) at 35 units/kg based on the INR of 4.3 1
- Administer vitamin K 5-10 mg intravenously if warfarin is the cause of elevated INR 1
- Consider fibrinogen level measurement and cryoprecipitate if fibrinogen is <100 mg/dL 1
- For refractory bleeding despite conventional therapy, recombinant Factor VIIa may be considered as rescue therapy 1, 2
Monitoring and Follow-up
- Repeat coagulation studies (platelet count, INR, aPTT) after initial transfusion to assess response 1
- Monitor for signs of continued bleeding from respiratory tract 1
- Assess for potential complications of transfusion (volume overload, transfusion reactions) 1
- Consider thromboelastography (TEG) or rotational thromboelastometry (ROTEM) if available for more targeted therapy 1
Special Considerations
- If patient has liver disease, anticipate more profound coagulopathy requiring more aggressive correction 1
- For patients with mechanical heart valves on warfarin, balance the risk of thrombosis against the risk of continued bleeding 1
- In cases of heparin-induced thrombocytopenia, avoid platelet transfusions as they may worsen thrombosis 1, 3
- Be aware that FFP transfusion alone may not fully correct complex coagulopathies in critically ill patients 4
Pitfalls to Avoid
- Do not delay transfusion of blood products while waiting for laboratory confirmation in cases of significant active bleeding 1
- Avoid using intravenous vitamin K alone for urgent reversal as it takes hours to correct INR 1
- Do not administer FFP for INR correction without addressing platelet count simultaneously in this scenario 1
- Be aware that early and aggressive correction of coagulopathy is associated with improved outcomes compared to delayed intervention 5
