Guidelines for Prevention and Management of Paracentesis‑Related Complications

Prevention of Vulvar Edema and Other Adverse Events

Upper‑abdominal puncture (left upper quadrant) or placement of the needle ≥ 8 cm from the midline and ≥ 5 cm above the symphysis pubis markedly reduces the risk of fluid tracking to the vulva. (Gut, 2021) [1][2]
Real‑time ultrasound guidance during paracentesis lowers the overall adverse‑event rate by approximately 68 %. (Gut, 2021) [1][2]

Injury to the inferior epigastric artery can produce bleeding that tracks to the vulva after lower‑abdominal paracentesis. (Gut, 2021) [1][2]

Inspection of the puncture site for expanding hematoma, active bleeding, or persistent fluid leak should be performed promptly after the procedure. (Gut, 2021) 3

Position the patient on the side opposite the puncture site for about 2 hours to help seal a leaking tract. (Gut, 2021) [3][1]
Applying a purse‑string suture around the drainage entry point is one of the most effective techniques to stop ongoing ascitic fluid leakage. (Gut, 2021) 3

Hemorrhagic complications after paracentesis occur in fewer than 1 per 1,000 procedures and are more frequently associated with renal failure than with coagulopathy. (Gut, 2021) [3][2]

Do not discontinue spironolactone or furosemide unless the patient becomes hemodynamically unstable; continued diuretic use is essential to prevent rapid re‑accumulation of ascites. (Journal of Hepatology, 2010) 4

For a leaking paracentesis site, the most effective management includes having the patient lie on the opposite side for two hours and/or placing a purse-string suture around the drainage site 5, 6, 7
Position the patient properly by having them lie on the side opposite to the paracentesis site for at least two hours to minimize continued leakage by reducing pressure on the puncture site 5, 8
Apply a purse-string suture around the paracentesis site as one of the most effective methods to stop persistent leakage 5, 8
Apply a purse-string suture around the paracentesis site, which is one of the most effective methods to stop persistent leakage, with evidence suggesting its effectiveness 7, 9

Use proper technique during insertion by employing the "Z-track" technique to ensure the puncture sites on the skin and peritoneum don't directly overlie each other 5, 8
Select an appropriate insertion site, such as the left lower quadrant, to minimize the risk of leakage during the procedure 10
Complete drainage in a single session by draining all ascitic fluid to dryness in one session to avoid leaving drains in overnight 5, 8
Consider ultrasound guidance to reduce adverse events when available 8, 9

Watch for signs of infection at the puncture site, as monitoring for complications is crucial in managing leaking paracentesis sites 11
