Management of Fluid Overload and Hypotension

Albumin Administration

The American College of Cardiology recommends albumin infusions to support intravascular volume while reducing extravascular fluid retention in patients with symptomatic hypovolemia 1
Dosage should be based on clinical indicators of hypovolemia, such as prolonged capillary refill time, tachycardia, hypotension, and oliguria, rather than serum albumin levels 1
In severe cases, daily albumin infusions of 1-4 g/kg may be necessary to improve intravascular volume 1
Consider administering an intravenous bolus of furosemide (0.5-2 mg/kg) at the end of each albumin infusion to prevent fluid accumulation 1

The American College of Cardiology suggests that loop diuretics remain the cornerstone therapy for volume overload, but must be used cautiously in hypotensive patients 2
Only use diuretics in the case of intravascular fluid overload with good peripheral perfusion 1
For diuretic resistance, consider higher doses of intravenous loop diuretics 2

The American College of Cardiology recommends considering ultrafiltration for patients with obvious volume overload to alleviate congestive symptoms when diuretic strategies are unsuccessful 3
Ultrafiltration may be particularly beneficial for patients with refractory congestion not responding to medical therapy 3
This approach moves water and small to medium-weight solutes across a semipermeable membrane, allowing for more sodium removal than diuretics alone 3

The World Journal of Emergency Surgery suggests that the aim of fluid therapy is to maintain intravascular volume, cardiac output, and tissue perfusion while avoiding salt and water overload 4
In high-risk patients, consider goal-directed fluid therapy using minimally invasive cardiac output monitoring to optimize stroke volume 4
Arterial hypotension should be treated with vasopressors when administering intravenous fluid boluses fails to improve stroke volume significantly 4

The American College of Cardiology recommends carefully monitoring fluid status through daily weight measurements, vital signs, fluid input/output, and clinical signs of systemic perfusion and congestion 2
Assess daily electrolytes and renal function while administering intravenous diuretics 2

The American College of Cardiology suggests avoiding excessive diuresis leading to intravascular volume depletion, which can worsen hypotension 5
Do not use diuretics in patients with marked hypovolemia or hyponatremia 1
Be cautious with high doses of furosemide (>6 mg/kg/day) for periods longer than 1 week due to risk of hearing loss 1
