How To Do Paracentesis
Contraindications to Paracentesis
Absolute contraindications Severe, uncorrectable disorders of blood coagulation Intestinal obstruction with bowel distention (unless an area of peritoneal fluid that can be safely entered has been identified using imaging studies) An infected abdominal wall Relative contraindications Poor patient cooperation Surgical scarring at the puncture site: The paracentesis site should be moved away from any area of scarring. Surgical scars can cause adherence of the bowel to the abdominal wall, increasing the risk of bowel perforation during paracentesis. Large intra-abdominal mass, or second or third trimester pregnancy: In these patients, paracentesis should be done with ultrasound guidance. Severe portal hypertension with abdominal collateral circulation: This disorder increases the risk of needle injury to dilated veins in the abdominal wall.
