Albumin (Human) 25%, USP

Category:

Plasma expander

Description:

Plasma volume expander made from pooled human venous plasma

Indications:

Emergency treatment of hypovolemic shock, burn therapy, cardiopulmonary bypass
Hypoproteinemia with or without edema, adult respiratory distress syndrome (ARDS)
Acute liver failure, neonatal hemolytic disease
Erythrocyte resuspension, sequestration of protein rich foods
Acute neophrosis

Contraindications:

Chronic nephrosis
History of CHF, renal insufficiency, or stabilized chronic anemia

Precautions:

Pregnancy category C
Monitor against signs of circulatory overload. Albumin 25% is hyperoncotic, therefore, in the presence of dehydration, albumin must be followed by addition of fluids.
In presence of hemorrhage, albumin should be supplemented by the transfusion of whole blood to treat the relative anemia associated with hemodilution. When circulating blood volume has been reduced, hemodilution following the administration of albumin persists for many hours. In patients with normal blood volume, hemodilution lasts for a much shorter time.
The rapid rise in blood pressure may follow the administration of a colloid with positive oncotic activity necessitates careful observation to detect and treat severed blood vessels which may not have bled at the lower blood pressure.

Adverse Reactions (Side Effects):

Rare: Such reactions may be allergic in nature or due to high plasma protein levels from excessive albumin administration. Allergic manifestations include urticaria, chills, fever, and changes in pulse, respiration and blood pressure.

Dosage:

Always administered by intravenous infusion; albumin 25% may be administered undiluted or diluted in 0.9% Sodium Chloride or 5% Dextrose in Water.

Hypovolemic shock:
The volume administered and the speed of infusion should be adapted to the response of the patient
Burns:
After a burn injury (usually 24 hours) there is a close correlation between the amount of albumin infused and the resultant increase in plasma colloid osmotic pressure. The aim should be to maintain the plasma albumin concentration in the region of 2.5 , plus or minus 0.5g, per 100ml with a plasma oncotic pressure of 22 mm Hg. This is best achieved by IV administration of albumin 25%. The duration of therapy is decided by the loss of protein from the burned areas and in the urine, In addition, oral or parenteral feeding with amino acids should be initiated, as the long-term administration of albumin should not be considered as a source of nutrition.
Hypoproteinemia with or without edema:
Unless the underlying pathology for hypoproteinemia can be corrected, the IV administration of albumin 25% must be considered purely symptomatic or supportive. The usual daily dose of albumin for adults is 50 to 75g and for children 25g. Patients with severe hypoproteinemia who continue to lose albumin may require larger quantities. Since hypoproteinemic patients usually have normal blood volumes, the rate of administration should not exceed 2 ml/min as more rapid injection may precipitate circulatory embarrassment and pulmonary edema.

Store at room temperature not exceeding 30 degrees C (86 degrees F).
