New Onset Ascites
- Establish etiology with the serum-ascites albumin gradient (SAAG)
Rule Out Spontaneous Bacterial Peritonitis (SBP)
- Have a very low threshold to perform a diagnostic paracentesis in cirrhotics
- Paracentesis should always be performed in a cirrhotic with new1
- Acute kidney injury
- Abdominal pain
- Guidelines suggest performing a diagnostic paracentesis on ALL cirrhotics admitted to the hospital to rule out SBP because2
- 12% of hospitalized cirrhotics have SBP
- 50% of patients with SBP are asymptomatic
- 50% of patients with SBP had another concurrent infection
- If a septic cirrhotic has a “dirty” UA, still should perform a para as apart of the “full-fever work up”
- Timely paracentesis can save lives
- Hospitalized cirrhotics had a 25% relative risk reduction in mortality if they received a diagnostic paracentesis3
Symptomatic Volume Removal
- Paracentesis is far superior to high dose diuretics to control large volume ascites4
- Paracentesis was 95% effective, whereas diuretics were only effective 75% of the time
- Paracentesis was associated with less AKI, encephalopathy, and a shorter length of stay compared to diuretics
- Large volume therapeutic paracentesis is the preferred management strategy followed by maintenance diuretics5
There are no absolute contraindications to paracentesis6, 7
- Weigh the risks and benefits for each patient
- Diagnostic paracentesis with a smaller gauge needle may be safer than the large bore needle used in therapeutic paracentesis
Hemodynamic instability and acute kidney injury
- Large volume paracentesis should be avoided in these situations as large volume shifts can worsen hypotension and decrease renal perfusion
Proceed with caution and ultrasound guidance if suspecting intra-abdominal obstacles like:
- Bowel obstruction
- Intra-abdominal adhesions
- Avoid surgical scars
- Distended bladder
