Ascites
• 85% of ascites is secondary to cirrhosis with portal hypertension
• Most common decompensation in cirrhosis
• 15% mortality at 1 year
• Paracentesis helps determine the cause of ascites: • Serum-ascites albumin gradient (SAAG) >11 is consistent with portal
hypertension
• Presence of ascites is an important consideration in any patient presenting to hospital

Long-term Management of Ascites
• Initiate a sodium-restricted diet to <2g/day
• Usual starting dose of diuretics • Spironolactone 100mg daily
• Lasix 40mg daily
![Page 35: Management of Decompensated Liver Disease · in cirrhosis with portal HTN •Infection is a common cause of morbidity and mortality in this setting •20% of patients have an infection](https://reader030.vdocument.in/reader030/viewer/2022040608/5ec8823637185c26cf048d65/html5/thumbnails/35.jpg)
HRS dx only made after IV fluids and r/o other causes • AKI in portal hypertension often IS NOT HRS
• Diagnosis: • Cirrhosis with ascites
• Serum Cr >133
• No improvement in Cr after 48hrs fluid resuscitation and discontinuation of diuretics
• No evidence of shock
• Absence of current or recent nephrotoxic agents
• Absence of parenchymal kidney disease
• Manage as AKI and rule out SBP
![Page 36: Management of Decompensated Liver Disease · in cirrhosis with portal HTN •Infection is a common cause of morbidity and mortality in this setting •20% of patients have an infection](https://reader030.vdocument.in/reader030/viewer/2022040608/5ec8823637185c26cf048d65/html5/thumbnails/36.jpg)
Medication considerations in decompensated cirrhosis
• ACEi and ARB • Adversely effects renal blood flow in portal HTN (particularly with ascites)
• Beta blockers • Can be detrimental in refractory ascites
• Metformin • Safe
• Statins • Safe
• NSAIDs • Avoid
• Acetaminophen • Safe in lower doses (up to 2g/day)
• Opioids/Benzodiazepines/Sleep aids • Be cautious
![Page 37: Management of Decompensated Liver Disease · in cirrhosis with portal HTN •Infection is a common cause of morbidity and mortality in this setting •20% of patients have an infection](https://reader030.vdocument.in/reader030/viewer/2022040608/5ec8823637185c26cf048d65/html5/thumbnails/37.jpg)
Summary
• Patients with cirrhosis presenting with GI bleeding require prophylactic antibiotics
• If hepatic encephalopathy is suspected, it will largely be determined by history and physical examination
• Spontaneous bacterial peritonitis is common in hospitalized patients and these patients should all have a diagnostic paracentesis
• AKI in the setting of cirrhosis is often not related to hepatorenal syndrome and this diagnosis should be reserved for patients where other causes have been ruled out and have been adequately fluid resuscitated
• A diagnosis of cirrhosis should prompt a review of the patient’s medications
