๐ Human Albumin Solution (HAS) is issued by the Trust blood bank. Like other plasma products, it is derived from fractionation of donated whole blood and is subject to the same traceability, consent, and reporting requirements.
Patients who decline blood products (e.g. for religious reasons) may also refuse albumin. โ
โน๏ธ About
Always check the BNF link here ๐ for prescribing advice.
- Colloidal fluid used selectively in specific clinical contexts, not routinely to โboost albumin levels.โ
โ๏ธ Mode of Action
- 4.5% HAS: iso-oncotic (โplasma oncotic pressure). Used as a volume expander in acute illness ๐ง.
- 20% HAS: hyperoncotic, draws interstitial fluid into intravascular space. Useful in paracentesis, SBP, hepatorenal syndrome.
๐ Indications & Dosing
- Volume expansion (4.5% HAS): burns, pancreatitis, trauma, perioperative complications (with crystalloids).
- Large-volume paracentesis (ascites drainage): 8 g albumin for each litre removed.
โ Give 100 mL of 20% HAS for every 3 L ascitic fluid drained (infuse over โฅ2 h).
- Spontaneous bacterial peritonitis (SBP):
โข Day 1: 1.5 g/kg 20% HAS
โข Day 3: 1 g/kg 20% HAS, continue until improvement.
- Hepatorenal syndrome (HRS):
โข Day 1: 1 g/kg 20% HAS
โข Day 2โ14: 0.5 g/kg/day until clinical improvement.
๐ซ Not Indicated
- Routine daily infusions in advanced liver cirrhosis offer no added benefit over standard care.
- Not recommended solely to correct hypoalbuminaemia in chronic liver disease.
โ ๏ธ Interactions
๐ Cautions
- Risk of fluid overload and precipitating heart failure or pulmonary oedema ๐ซ.
- 20% HAS is hyperoncotic โ expands plasma volume significantly.
- Always issued on a named patient basis via blood bank.
๐ซ Contraindications
โ Side Effects
- Circulatory overload (โ risk in elderly or cardiac dysfunction).
- Infusion reactions / hypersensitivity.
- Theoretical risk of transmission of nvCJD (prion disease).
