The process of peritoneal drainage can be carried out effectively and safely by employing a specific ultrasound-guided technique for the following [23] :

  • Confirm the presence of ascites
  • Quantify and qualify the ascites
  • Determine trajectory and depth
  • Avoid superficial blood vessels
  • Perform an ultrasound-assisted paracentesis
  • Perform an ultrasound-guided paracentesis
  • Check the position of the wire prior to dilating
