Hemorrhagic Ascites: Evaluation and Management
Hemorrhagic ascites in cirrhosis is a marker of advanced disease and poor prognosis, requiring immediate diagnostic paracentesis to exclude life-threatening causes, followed by supportive management and urgent transplant evaluation.
Definition and Clinical Significance
Hemorrhagic ascites is defined as ascitic fluid with a red blood cell (RBC) count ≥10,000 cells/μL. 1
- This finding occurs in approximately 19% of cirrhotic patients undergoing paracentesis and carries significantly worse outcomes than non-hemorrhagic ascites 1
- Patients with hemorrhagic ascites have higher mortality at 1 month (87% vs 72%), 1 year (72% vs 50%), and 3 years (61% vs 41%) compared to matched controls with non-hemorrhagic ascites 1
- Hemorrhagic ascites is an independent predictor of mortality (HR 1.34,95% CI 1.07-1.68) even after adjusting for MELD score, ICU care, and hepatocellular carcinoma 1
Immediate Diagnostic Evaluation
Mandatory Paracentesis
Perform diagnostic paracentesis immediately in all patients with hemorrhagic ascites, regardless of coagulopathy or thrombocytopenia. 2
- Coagulopathy should preclude paracentesis only when clinically evident fibrinolysis or disseminated intravascular coagulation is present—these conditions occur in less than 1 per 1,000 procedures 2
- There is no data-supported cutoff of INR or platelet count beyond which paracentesis should be avoided 2
- Fresh frozen plasma or platelet transfusion before paracentesis is not recommended 2
Essential Ascitic Fluid Analysis
Collect at least 10 mL of fluid and inoculate into aerobic and anaerobic blood culture bottles at bedside before any antibiotics. 2, 3
Send fluid for:
- Neutrophil count (absolute PMN >250 cells/mm³ diagnoses spontaneous bacterial peritonitis requiring immediate antibiotics) 2, 3
- Total protein and albumin with simultaneous serum albumin to calculate SAAG 2
- Cell count with differential to quantify RBC count and confirm hemorrhagic nature 1
- Bacterial cultures in blood culture bottles 2, 3
Calculate Serum-Ascites Albumin Gradient (SAAG)
SAAG ≥1.1 g/dL indicates portal hypertension with 97% accuracy and confirms cirrhotic ascites as the underlying cause. 2, 4
- SAAG <1.1 g/dL suggests non-portal hypertensive causes such as peritoneal carcinomatosis, tuberculosis, or pancreatic disease 2, 4
Differential Diagnosis of Hemorrhagic Ascites
Most Common Causes in Cirrhosis
The three most important causes to exclude immediately are:
Hepatocellular carcinoma (most common malignant cause in cirrhosis) 1
Traumatic tap (iatrogenic blood contamination)
- RBC count typically decreases between first and last tubes collected
- Fluid does not clot (unlike traumatic tap where fresh blood may clot) 5
Spontaneous bacterial peritonitis
Less Common but Critical Causes
- Peritoneal carcinomatosis (SAAG <1.1 g/dL) 4, 5
- Tuberculous peritonitis (SAAG <1.1 g/dL, high lymphocyte count) 4, 5
- Ruptured hepatocellular carcinoma (acute presentation with hemodynamic instability) 1
- Coagulopathy-related bleeding (rare, but consider if INR >8 or platelets <20,000/μL) 2
Immediate Management
Therapeutic Paracentesis
For tense or symptomatic hemorrhagic ascites, perform large-volume paracentesis removing all accessible fluid in a single session. 2, 3
- When removing >5 liters, administer albumin at 8 g per liter of ascites removed to prevent post-paracentesis circulatory dysfunction 2, 3, 6
- Complete drainage should occur over 1-4 hours 3, 6
- Albumin should be infused after paracentesis completion, not during the procedure 3, 6
Sodium Restriction and Diuretics
Initiate dietary sodium restriction to <2 g/day (88 mmol/day) immediately. 2, 3
- Start combination diuretic therapy with spironolactone 100 mg daily plus furosemide 40 mg daily 2, 3
- Fluid restriction is not indicated unless serum sodium <125 mmol/L 2, 3
- Never use furosemide as monotherapy—it is less effective than spironolactone in portal hypertension 3
Monitoring for Complications
Patients with hemorrhagic ascites require intensive monitoring because they have significantly higher rates of:
Acute kidney injury (p <0.001 compared to non-hemorrhagic ascites) 1
ICU-level care requirements (p=0.01 compared to non-hemorrhagic ascites) 1
- Monitor for hemodynamic instability, hepatic encephalopathy, and sepsis 1
Spontaneous bacterial peritonitis (p <0.001 compared to non-hemorrhagic ascites) 1
- Maintain low threshold for repeat paracentesis if fever, abdominal pain, or encephalopathy develops 2
Liver Transplantation Evaluation
All patients with hemorrhagic ascites should be referred urgently for liver transplantation evaluation, as this finding indicates advanced decompensated cirrhosis with 5-year survival reduced to 30%. 2, 3, 7
- Development of ascites (hemorrhagic or non-hemorrhagic) is an indication for transplant evaluation 2, 3, 7
- Hemorrhagic ascites is an independent predictor of mortality beyond MELD score 1
- Patients not eligible for transplant should receive palliative care consultation 2, 7
Critical Pitfalls to Avoid
- Never withhold paracentesis due to coagulopathy—serious bleeding complications occur in <1/1,000 procedures, and diagnostic information is life-saving 2
- Never assume hemorrhagic ascites is simply due to cirrhosis—always exclude HCC, peritoneal carcinomatosis, and tuberculosis with appropriate imaging and fluid analysis 4, 1, 5
- Never give fresh frozen plasma or platelets prophylactically before paracentesis—this practice lacks evidence and delays diagnosis 2
- Never restrict fluids unless serum sodium is <125 mmol/L—unnecessary restriction worsens quality of life without benefit 2, 3
- Never use NSAIDs in patients with ascites—they reduce diuretic efficacy and worsen renal function 6
