Age: 58 • Gender: Male • Setting: Emergency Triage
Clinical Presentation & History
Day-3 inpatient with cirrhosis and ascites now oliguric with doubling of serum creatinine despite apparent neutral fluid balance. Requires rapid recognition of acute kidney injury progression from prerenal azotemia to hepatorenal syndrome. 58-year-old male with known cirrhosis admitted 3 days ago for tense ascites requiring large-volume paracentesis. Now on spironolactone 200 mg/day and furosemide 80 mg/day. Has been on nadolol 40 mg/day for esophageal variceal prophylaxis. Reports decreasing urine output over the past 36 hours.
Acute Resuscitation Milestones & Priorities
Clinical phases and key interventions encountered in this emergency module:
In any cirrhotic with ascites and AKI, always hold diuretics and rule out SBP before labeling HRS.
HRS-AKI is a diagnosis of exclusion: no shock, no nephrotoxins, no improvement after 48h of volume expansion, and intrinsic renal disease excluded.
Terlipressin + albumin is the first-line vasoconstrictor therapy; cardiac ischemia mandates dose reduction, not discontinuation, when renal response is evident.
NSBBs should be reduced or held when MAP < 65-70 mmHg or in refractory ascites.
Diagnostic paracentesis precedes empiric antibiotics to preserve microbiological yield.
