In sepsis patients, prolonged prothrombin time (PT) with normal thromboelastometry did not lead to severe bleeding during invasive procedures. This finding may help reduce unnecessary fresh frozen plasma transfusions.
Area of Science:
- Coagulation Medicine
- Critical Care
Background:
- Sepsis frequently causes prolonged prothrombin time (PT).
- Thromboelastometry, a global coagulation test, may show normal results in sepsis.
- The clinical significance of prolonged PT with normal thromboelastometry in sepsis is unclear.
Purpose of the Study:
- To investigate if prolonged PT and normal thromboelastometry correlate with severe bleeding in sepsis patients undergoing invasive procedures.
Main Methods:
- Retrospective analysis of 76 sepsis patients undergoing low or high-risk bleeding invasive procedures between 2013-2016.
- Coagulation assessed using thromboelastometry (EXTEM test) and PT (INR/PR).
- Severe bleeding occurrence monitored during procedures and 24 hours post-procedure.
Main Results:
- Patients with prolonged PT (median INR 1.59, PR 1.5) and normal thromboelastometry showed no severe bleeding during procedures.
- Sepsis can present with prolonged PT despite normal global coagulation tests.
Conclusions:
- Prolonged PT with normal thromboelastometry in sepsis patients undergoing invasive procedures is not associated with severe bleeding.
- This coagulation assessment strategy may help avoid unnecessary fresh frozen plasma administration.
