Clinical indications for human serum albumin
Developments in Biological Standardization
|January 1, 1980
Summary
Human serum albumin is inappropriate for nutrition and its transport functions are inconclusive. However, albumin effectively manages blood volume and hypoproteinemia in patients with intact capillaries.
Area of Science:
- Biochemistry
- Clinical Medicine
- Pharmacology
Background:
- Human serum albumin (HSA) has three primary clinical indications: nutrition, binding/transport, and volume expansion.
- Its use as an intravenous nutrient is inappropriate.
- Clinical evidence for HSA's binding and transport roles is inconclusive.
Purpose of the Study:
- To evaluate the established and debated clinical applications of human serum albumin.
- To determine appropriate clinical use based on current evidence.
Main Methods:
- Literature review of studies on human serum albumin's clinical applications.
- Analysis of data regarding HSA's effects on blood volume, hypoproteinemia, and capillary permeability.
Main Results:
- HSA is effective for managing blood volume and hypoproteinemia in patients with intact capillaries.
- The role of HSA in capillary permeability lesions, seen in severe injuries and septic pulmonary failure, is debated.
- Contradictory data exist regarding capillary permeability, but consensus suggests maintaining serum albumin above 30 g/L or total protein above 50 g/L.
Conclusions:
- HSA's efficacy is firmly established for volume expansion and treating hypoproteinemia in patients with intact capillaries.
- Further research is needed to clarify HSA's role in capillary permeability disorders.
- Clinical guidelines recommend maintaining specific serum protein levels in critical care settings.
