The benefit of albumin administration in the critically ill patient is unpr
oven. Epidemiological evidence suggests that there is an increase in death
among patients with burns, hypoalbuminaemia, and hypotension treated with h
uman albumin solution (HAS). In critical illness, hypoalbuminaemia is a res
ult of transcapillary leak, decreased synthesis, large volume body fluid lo
sses and dilution caused by fluid resuscitation. When treating patients wit
h hypoalbuminaemia, efforts must be centred around correction of the underl
ying disorder rather than reversal of hypoalbuminaemia. Problems with using
albumin arise because it is an expensive blood product, and can result in
systemic changes that include cardiovascular, haematological, renal, pulmon
ary, and immunological effects.
