Study Notes
Serum Albumin Overview
- Serum Albumin is classified as a fluid replacement agent, primarily used to manage blood volume and maintain oncotic pressure.
- Acts as a blood product and is classified as a colloid, which helps to retain fluid in the intravascular space.
Composition and Characteristics
- Normal serum albumin is a protein sourced from whole blood or plasma, essential for various physiological functions.
- Plasma protein fraction, known as Plasmanate, is an albumin product comprising 83% albumin and 17% plasma globulins.
Mechanism of Action
- Albumin increases blood oncotic pressure, facilitating fluid movement from tissues into the bloodstream.
- It is effective in treating conditions such as hypovolemic shock and hypoproteinemia, particularly in patients with hepatic cirrhosis.
Administration Details
- Available in two concentrations:
- 5% (isotonic)
- 25% (hypertonic)
- Has an immediate onset of action, providing rapid therapeutic benefits.
Nursing Considerations
- When administering albumin, especially the 25% hypertonic solution, it is crucial to infuse it slowly while monitoring the percentage prescribed.
- For 5% albumin (50 grams), it is typically packaged in 250 ml and can be infused at a rate of 1-2 mL/min, depending on patient condition and therapeutic goals.
- The 25% albumin preparation contains 12.5 grams in a 50 ml volume, with specific infusion rates determined by the patient's response.
