What is the best course of treatment for a patient with End-Stage Renal Disease (ESRD) and Congestive Heart Failure (CHF) who has missed dialysis for two weeks and is now fluid overloaded?

From the Guidelines

The best course of treatment for a patient with ESRD and CHF who has missed dialysis for two weeks and is now fluid overloaded is immediate hospitalization for urgent hemodialysis with careful fluid removal, alongside the administration of intravenous loop diuretics to relieve symptoms and reduce volume excess. When managing such a patient, it is crucial to balance the need for rapid fluid removal with the risk of hemodynamic instability, as evidenced by the 2013 ACCF/AHA guideline for the management of heart failure 1. Key considerations include:

• Initial ultrafiltration goal of 1-2 liters per session during hemodialysis to avoid excessive fluid removal and potential hypotension.
• Administration of intravenous loop diuretics, such as furosemide 80-160mg, to help reduce fluid overload, although their effectiveness may be limited in patients with ESRD.
• Continuous monitoring of the patient's condition, including urine output and signs of congestion, to adjust diuretic doses accordingly, as recommended for hospitalized patients with significant fluid overload 1.
• Daily measurement of serum electrolytes, urea nitrogen, and creatinine concentrations to guide the management of fluid and electrolyte balance during the use of intravenous diuretics or active titration of heart failure medications 1.
• Provision of oxygen supplementation to maintain saturation above 92% and placement in an upright position to ease breathing.
• Implementation of dietary restrictions, including less than 2g of sodium daily and fluid restriction to 1-1.5 liters daily, to manage fluid overload.
• Continuous cardiac monitoring due to the high risk of arrhythmias from electrolyte imbalances, particularly hyperkalemia.
• Immediate laboratory tests, including electrolytes, BUN, creatinine, and arterial blood gases, to assess the patient's condition and guide further management. This approach prioritizes the reduction of morbidity and mortality while improving the quality of life for the patient by addressing the immediate concerns of fluid overload and electrolyte imbalance, and by establishing a plan for sustainable dialysis to prevent future complications.

From the FDA Drug Label

The principal signs and symptoms of overdose with Furosemide are dehydration, blood volume reduction, hypotension, electrolyte imbalance, hypokalemia and hypochloremic alkalosis, and are extensions of its diuretic action. Treatment of overdosage is supportive and consists of replacement of excessive fluid and electrolyte losses. Hemodialysis does not accelerate furosemide elimination.

The best course of treatment for a patient with End-Stage Renal Disease (ESRD) and Congestive Heart Failure (CHF) who has missed dialysis for two weeks and is now fluid overloaded is to:

• Replace excessive fluid and electrolyte losses
• Monitor serum electrolytes, carbon dioxide level, and blood pressure frequently
• Ensure adequate drainage
• Resume dialysis as soon as possible to address the fluid overload and electrolyte imbalances associated with missed dialysis sessions 2

From the Research

Concerns and Complications

• A patient with End-Stage Renal Disease (ESRD) and Congestive Heart Failure (CHF) who has missed dialysis for two weeks and is now fluid overloaded is at risk for several complications, including worsening renal function and cardiac decompensation 3.
• The patient's fluid overload may be exacerbated by the missed dialysis sessions, and aggressive fluid removal may be necessary to alleviate symptoms 3.
• Electrolyte imbalances, such as hyperkalemia or hypokalemia, may also occur due to the missed dialysis sessions and require careful management 4, 5.

Treatment Options

• Tolvaptan, an oral arginine vasopressin type 2 receptor antagonist, may be a potential adjunct therapy for patients with ESRD and CHF who are refractory to diuretics and have excessive fluid retention 6, 7.
• Hemodialysis may be necessary to remove excess fluid and electrolytes, and the choice of dialysate can help balance electrolyte disorders and prevent complications 4, 5.
• Furosemide, a loop diuretic, may also be used to treat fluid retention, but its use may be limited by the patient's renal function and the risk of worsening renal function 3, 7.

Management Strategies

• Close monitoring of the patient's fluid status, electrolyte levels, and cardiac function is necessary to guide treatment and prevent complications 3, 4.
• The patient's dialysis regimen may need to be adjusted to accommodate their fluid and electrolyte needs, and the use of ultrafiltration may be necessary to remove excess fluid 4.
• Medications, such as tolvaptan or furosemide, may be used in conjunction with dialysis to manage fluid retention and electrolyte imbalances 6, 7.
