1. Weaning and De‐escalation of Vasoconstrictors and Albumin

Systematic tapering of terlipressin and albumin is critical to minimize the risks of rebound hypotension and detrimental fluid shifts as renal parameters normalize and the patient stabilizes.

Clinical Criteria to Initiate Wean

• Mean Arterial Pressure (MAP) sustained at or above 65 mm Hg for at least 24 hours without escalating support.
• Serum creatinine (SCr) has decreased and is sustained at or below 1.5 mg/dL.
• Urine output has improved to greater than 0.5 mL/kg/h over a 24-hour period.

Agent Selection & Taper Strategy

• Terlipressin: Reduce the dose by 25% every 24–48 hours. Maintain the infusion until the rate is low (e.g., ≤0.5 mg IV q6h), then consider initiating an enteral midodrine bridge before complete discontinuation.
• Albumin: Decrease the daily dose by approximately 25% per day. This taper should be guided by clinical assessment of fluid balance, central venous pressure (CVP) trends, or point-of-care ultrasound (POCUS) assessment of volume status.

Monitoring During Taper

• Closely monitor MAP, SCr, lactate, and clinical signs of perfusion (e.g., capillary refill, mentation) every 6–12 hours.
• Utilize CVP or POCUS to frequently reassess intravascular volume and guide fluid management.

Contraindications & Pitfalls

• Avoid abrupt discontinuation of vasoconstrictors, as this carries a high risk of rebound hypotension and acute kidney re-injury.
• Exercise extreme caution in patients with known ischemic heart disease, peripheral vascular disease (PVD), or a history of mesenteric ischemia, as vasoconstrictors can exacerbate these conditions.

2. Conversion from IV to Enteral Medications

A successful transition from intravenous to enteral vasoconstrictors and diuretics is a key milestone that facilitates ICU discharge, reduces costs, and improves continuity of care.

Candidate Agents for Enteral Conversion

• Midodrine: An oral alpha-1 agonist that serves as the primary enteral vasoconstrictor.
• Diuretics: Spironolactone and furosemide can be resumed to manage ascites and fluid overload once hemodynamically stable.
• Non-selective Beta-Blockers (NSBBs): Should be cautiously re-introduced if indicated for primary or secondary prophylaxis of variceal bleeding.

Dosing and Administration

• Dosing Equivalence: While not exact, a norepinephrine infusion of approximately 8 µg/min is roughly equivalent to midodrine 7.5 mg three times daily. Midodrine has a bioavailability of about 50% with a peak effect around 1 hour post-dose.
• Enteral Access: Confirm that tablets can be crushed or if a liquid formulation is available. It is crucial to flush the feeding tube thoroughly before and after administration. Hold tube feeds for 30 minutes before and after midodrine administration to maximize absorption.

Monitoring Post-Conversion

• Check MAP response within 4 hours of the first enteral dose.
• Monitor daily serum creatinine and electrolytes for the first 48 hours.
• Routinely inspect tube patency and monitor for signs of malabsorption, such as diarrhea or high gastric residuals.

3. Post-ICU Syndrome Identification and Mitigation

Patients recovering from HRS are at high risk for Post-ICU Syndrome (PICS), a constellation of long-term cognitive, psychological, and physical deficits. Early recognition and implementation of the ABCDEF bundle are essential to improve long-term outcomes.

High-Risk Patient Profile

• Vasoconstrictor therapy lasting more than 3 days
• Episodes of delirium or use of deep sedation
• Prolonged immobility or mechanical ventilation

The ABCDEF Bundle for PICS Prevention

• A: Assess, Prevent, and Manage Pain. Use validated tools like the Critical-Care Pain Observation Tool (CPOT).
• B: Both Spontaneous Awakening Trials (SATs) and Spontaneous Breathing Trials (SBTs). Daily interruption of sedation to assess neurologic function.
• C: Choice of Analgesia and Sedation. Prefer lighter sedation and agents like dexmedetomidine over benzodiazepines.
• D: Delirium: Assess, Prevent, and Manage. Monitor with the Confusion Assessment Method for the ICU (CAM-ICU) and use nonpharmacologic management strategies.
• E: Early Mobility and Exercise. Initiate passive range of motion, progressing to active mobility, ideally within 48 hours of stabilization.
• F: Family Engagement and Empowerment. Involve family in daily rounds, care planning, and education.

4. Medication Reconciliation and Discharge Counseling

A structured, multidisciplinary handoff process combined with clear patient education is paramount to preventing medication errors, ensuring adherence, and reducing the risk of early hospital readmission.

Comprehensive Medication Review

• Systematically compare pre-admission, ICU, and planned discharge medication lists.
• Explicitly discontinue all potential nephrotoxins (e.g., NSAIDs, aminoglycosides) and unnecessary vasodilators.
• Avoid angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs) unless absolutely necessary and with a plan for close outpatient monitoring.

Patient and Caregiver Education

• Signs of HRS Recurrence: Educate on recognizing decreased urine output, rapid weight gain, and increasing abdominal girth.
• Dietary Restrictions: Reinforce the importance of fluid restriction (typically 1.5–2 L/day) and sodium restriction (≤2 g/day).
• Monitoring Schedule: Provide a clear schedule for outpatient lab monitoring, including SCr and electrolytes at days 3 and 7 post-discharge.

Structured Handoff (SBAR Format)

• Situation: Patient’s course of HRS, current clinical status, and reason for transfer/discharge.
• Background: Details of the vasoconstrictor/albumin taper, final enteral regimen, and key events during hospitalization.
• Assessment: Final MAP, SCr, urine output, and fluid balance data.
• Recommendation: Specific plan for outpatient follow-up, pending labs, and contact information for the hepatology/nephrology team.
