How To Use Continuous Wall Suction for Paracentesis

 

Recommended limits for total fluid removal vary depending on the source, but the consensus among guidelines is 5–6 liters without the need for volume expanders to lessen chances of major complications.

 

Paracentesis (ascitic tap)…

Paracentesis is usually done in a lateral decubitus position (or supine, for large volumes). The level of the ascites fluid is percussed and a needle is inserted in either in the midline(2-3 cm below umbilicus) or lateral lower quadrant (lateral to rectus abdominus muscle, 2-4 cm superomedial to anterior superior iliac spine). This positioning prevents puncture of the inferior epigastric arteries; visible superficial veins and surgical scars should be avoided too. To reduce risk of ascites fluid leak, the needle is inserted either with a z-tracking technique, or at a 45-degree angle.
