Introduction: The Fragile Hemodynamic Equilibrium
Patients living with decompensated liver cirrhosis represent some of the most complex, high-risk presentations arriving at the Acute Medical Unit (AMU) and Same Day Emergency Care (SDEC) unit. Cirrhosis alters baseline physiology, inducing splanchnic vasodilation, relative intravascular depletion, hyperdynamic circulation, and profound immune dysfunction.
When a patient with stable cirrhosis experiences acute decompensation—manifesting as new or worsening ascites, hepatic encephalopathy, acute gastrointestinal bleeding, or acute kidney injury—the window for targeted intervention is narrow. Small delays in antibiotic administration, inappropriate fluid resuscitation, or missed subclinical infection rapidly precipitate multi-organ failure and death.
Building on our acute resuscitation and shock management protocols in Massive PE vs. Cardiac Tamponade: Bedside Management of Obstructive Shock, navigating acute liver failure requires systematically triaging the three major life-threatening complications of portal hypertension.
1. Spontaneous Bacterial Peritonitis (SBP): Diagnostic Paracentesis First
Spontaneous Bacterial Peritonitis (SBP) is an infection of ascitic fluid without an intra-abdominal, surgically treatable source. It is notoriously subtle—often presenting without fever, severe abdominal pain, or peritoneal signs.

[CONFIRMED DIAGNOSIS OF SBP]
(Immediate IV Ceftriaxone + IV Human Albumin)
Key Management Imperatives:
Mandatory Bedside Diagnostic Tap: Every cirrhotic patient admitted with acute deterioration, confusion, gastrointestinal bleeding, or new/worsening ascites must undergo diagnostic paracentesis within 2 hours of arrival.
Empiric Antibiotic Therapy: Initiate IV Ceftriaxone $2\text{ g}$ daily immediately upon identifying an ascitic Polymorphonuclear (PMN) count $\ge 250\text{ cells/mm}^3$ ($0.25 \times 10^9/\text{L}$).
Albumin Infusion for Renal Protection: SBP frequently precipitates acute kidney injury. Administer 20% Human Albumin Solution (HAS) at $1.5\text{ g/kg}$ body weight on Day 1, followed by $1.0\text{ g/kg}$ on Day 3. This significantly reduces the incidence of Hepatorenal Syndrome and mortality.
2. Hepatorenal Syndrome (HRS-AKI): Unmasking Functional Renal Failure
Hepatorenal Syndrome-Acute Kidney Injury (HRS-AKI) is a functional renal failure resulting from severe splanchnic vasodilation and compensatory renal vasoconstriction.
+-------------------------------------------------------------------------------+
| DIAGNOSTIC CRITERIA FOR HRS-AKI |
+-------------------------------------------------------------------------------+
| 1. CIRRHOSIS & ASCITES| Confirmed diagnosis of advanced liver cirrhosis. |
| 2. AKI DIAGNOSIS | Meets KDIGO criteria (e.g., serum creatinine increase |
| | ≥ 26.5 µmol/L within 48 hrs or ≥ 50% from baseline). |
| 3. NO RESPONSE | No improvement in serum creatinine after 48 hrs of |
| | diuretic withdrawal AND volume expansion with HAS. |
| 4. EXCLUDE SHOCK | Absence of septic shock, structural kidney disease |
| | (no proteinuria/hematuria), and nephrotoxic drugs. |
+-------------------------------------------------------------------------------+
Therapeutic Strategy:
Stop Offending Agents: Immediately discontinue all diuretics (Spironolactone, Furosemide), antihypertensives, and nephrotoxic drugs (NSAIDs, aminoglycosides).
Volume Expansion: Administer 20% Human Albumin Solution ($1\text{ g/kg/day}$ for 48 hours).
Vasoactive Therapy: If AKI persists despite volume expansion, commence Terlipressin (continuous IV infusion starting at $2\text{ mg/day}$, titrating up to $12\text{ mg/day}$) combined with HAS to restore effective arterial blood volume and renal perfusion.
For patients presenting with acute metabolic shifts or electrolyte derangements alongside renal dysfunction, integrate the emergency stabilization steps from Hyperkalemia Emergencies in the AMU.
3. Acute Variceal Bleeding: The Vasoactive-Antibiotic-Endoscopy Triad
Upper gastrointestinal bleeding in a cirrhotic patient is a catastrophic medical emergency requiring rapid, protocolized resuscitation.
+-------------------------------------------------------------------------------+
| ACUTE VARICEAL BLEED RESUSCITATION TRIAD |
+-------------------------------------------------------------------------------+
| 1. VASOACTIVE DRUGS | Start Terlipressin (2 mg IV bolus) or Octreotide |
| | immediately on suspected presentation—BEFORE endoscopy. |
| 2. ANTIBIOTICS | Administer IV Ceftriaxone (1 g/day). Reduces re-bleeding|
| | and mortality significantly in variceal hemorrhage. |
| 3. RESTRICTIVE TRANS| Target Hb 70–80 g/L. Over-transfusion elevates portal |
| | pressures and worsens active variceal hemorrhage. |
+-------------------------------------------------------------------------------+
Procedural & Airway Principles:
Emergency Endoscopy: Perform therapeutic OGD within 12 hours of presentation once the patient is hemodynamically stabilized.
Airway Protection: Patients with severe active hematemesis and high-grade Hepatic Encephalopathy require elective endotracheal intubation prior to endoscopy to prevent massive aspiration.
When acute hepatic encephalopathy presents as subtle confusion or lethargy, rule out co-existing neurocognitive conditions or delirium using the screening frameworks in Acute Delirium vs. Dementia on the Intake.
4. Summary Checklist for the Acute Intake
+-------------------------------------------------------------------------------+
| DECOMPENSATED CIRRHOSIS INTAKE CHECKLIST |
+-------------------------------------------------------------------------------+
| • Diagnostic Tap | Perform ascitic tap < 2 hrs; check PMN count & culture. |
| • Infection Screen | Send bloods, urine, sputum, and chest X-ray for sepsis.|
| • Medication Stop | Pause diuretics, ACEi/ARBs, NSAIDs, and sedatives. |
| • Early Drugs | Administer early antibiotics and Terlipressin if bleeding.|
| • Encephalopathy | Start Lactulose and Rifaximin for acute encephalopathy. |
+-------------------------------------------------------------------------------+
Safety Escalation: Cirrhotic patients with refractory SBP, worsening HRS-AKI, or uncontained variceal bleeding carry a extremely high risk of rapid decompensation. Early escalation to Gastroenterology/Hepatology and the Critical Care Outreach Team (CCOT) is essential, following the escalation principles detailed in Beyond NEWS2: Martha’s Rule, the PIER Framework, and Escalating the Deteriorating Inpatient.
Furthermore, when evaluating cirrhotic patients presenting with atypical shortness of breath or fluid overload, utilize the bedside ultrasound protocols in Point-of-Care Ultrasound (POCUS) on the Acute Take and cross-reference diagnostic features with ADHF vs. Severe COPD Exacerbation: AMU Diagnostic Overlap.
