Ultrasound-guided abdominal paracentesis rarely causes bleeding complications, even with low platelet counts or prolonged prothrombin times. Routine correction of these conditions before the procedure may not be necessary.

Area of Science:

  • Emergency Medicine
  • Gastroenterology
  • Interventional Radiology

Background:

  • Abdominal paracentesis is a common procedure in emergency departments.
  • Coagulopathy, including thrombocytopenia and prolonged prothrombin time, can increase bleeding risk.
  • The necessity of correcting these abnormalities before ultrasound-guided paracentesis is debated.

Purpose of the Study:

  • To evaluate bleeding complications and other adverse events associated with ultrasound-guided abdominal paracentesis.
  • To assess the impact of thrombocytopenia and prolonged prothrombin time on these complications.

Main Methods:

  • Prospective enrollment of patients undergoing ultrasound-guided abdominal paracentesis in a tertiary emergency department.
  • Collection of patient demographics, pre-procedure international normalized ratio (INR), and platelet counts.

  • Analysis of procedure-related complications, specifically bleeding events.

    • Main Results:

    • 410 paracentesis procedures in 163 patients were analyzed over 2 years.
    • Minor cutaneous bleeding occurred in 0.5% of procedures (0.6% of patients).
    • No significant bleeding or complications were observed, even in patients with marked thrombocytopenia or prolonged INR.

    Conclusions:

    • Bleeding complications from ultrasound-guided abdominal paracentesis are infrequent and typically mild.
    • Pre-procedure international normalized ratio or platelet count did not significantly correlate with bleeding risk.
    • Routine correction of coagulopathy before this procedure may be unnecessary.
