1 g/kg 1-2 hr before transfusion

Available forms:
Inj (5%) 50 mg/ml, (25%) 250 mg/ml

PHARMACOKINETICS

In hyponutrition states, metabolized as protein/energy source; terminal half-life 21 days

INTERACTIONS
Drug/Lab Test

Increase:
serum albumin

NURSING CONSIDERATIONS
Assess:

• 
Blood studies Hct, Hgb; if serum protein declines, dyspnea, hypoxemia can result

• 
Decreased B/P, erratic pulse, respiration

• 
I&O ratio: urinary output may decrease

 
Circulatory/pulmonary overload
:
CVP, pulmonary wedge pressure distended neck veins indicate circulatory overload; shortness of breath, anxiety, insomnia, expiratory crackles, frothy blood-tinged cough, cyanosis indicate pulmonary overload


 
Allergy: fever, rash, itching, chills, flushing, urticaria, nausea, vomiting, hypotension, requires discontinuation of inf, use of new lot if therapy reinstituted; premedicate with diphenhydrAMINE

Perform/provide:

• 
Adequate hydration before, during administration

• 
Check type of albumin; some stored at room temp, some need to be refrigerated, use within 4 hr of opening

Evaluate:

• 
Therapeutic response: increased B/P, decreased edema, increased serum albumin levels, increased plasma protein

Teach patient/family:

• 
Reason for product; to report hypersensitivity

Unlabeled uses:
Hyperkalemia in dialysis patients

CONTRAINDICATIONS:

Hypersensitivity to sympathomimetics, tachydysrhythmias, severe cardiac disease, heart block

Storage in light-resistant container; do not expose to temperatures of more than 86° F (30° C)

Evaluate:

• 
Therapeutic response: absence of dyspnea, wheezing after 1 hr, improved airway exchange, improved ABGs

Teach patient/family:

• 
To use exactly as prescribed; to take missed dose when remembered, alter dosing schedule; not to use OTC medications; that excess stimulation may occur

• 
About use of inhaler: review package insert with patient; use demonstration; return demonstration; shake, prime before 1st use and when not used for >2 wk; release 4 test sprays into air, away from the face

• 
To avoid getting aerosol in eyes (blurring of vision may result) or using near flames or sources of heat

• 
To wash inhaler in warm water daily and dry; to track number of inhalations used and to discard product when labeled inhalations have been used

• 
To avoid smoking, smoke-filled rooms, persons with respiratory infections

 
That
paradoxical bronchospasm
may occur; to stop product immediately, call prescriber
