Human albumin: benefits
resuscitation by intravenous administration of crystalloids and albumin, combined with vasoactive amines and early surgical and/or antibiotic therapy of infection, are crucial in the treatment of severe sepsis and septic shock. Artificial colloids are harmful in these situations. Updated guidelines14 suggest the use of albumin in the presence of at least one the following conditions: ● evidence of increased capillary permeability (pulmonary oedema and/ or oedema peripheral);
● failure to respond to the initial administration of at least 2 litres of crystalloid.
In surgical patients, according to guidelines used by some hospitals, the use of albumin may be indicated in patients undergoing major surgery (resection liver> 40%, large bowel resection) if, after normalisation blood volume, serum albumin is <2 g/dL.9,15

in cardiac surgery is recommended in various guidelines for both filling of the heart-lung machine and perioperatively to reduce oedema.16
have been shown in several clinical studies and meta-analysis to increase postoperative bleeding and number of reoperations.17
In burns, albumin is not the therapy of first choice in the first 24 hours, when crystalloids are to be used. In accordance with guidelines, albumin solutions are associated with crystalloids when burns cover more than 30% body surface area and with albumin levels less than 20g/l or when crystalloid therapy was not effective in the correction of hypovolemia.18 For plasmapheresis, human albumin is primarily recommended as compared to crystalloids or synthetic colloids, when the plasma exchange procedure concerns large plasma volumes (> 20 ml/kg in one sitting, or > 20ml/kg per week in case of repeated procedures). Crystalloid and albumin/crystalloid combinations are cost-effectiveness alternatives for plasmapheresis at smaller volumes.10 In ovarian hyperstimulation syndrome, use of albumin solutions has been investigated in several clinical studies that showed effectiveness of colloid administration in the prevention of this syndrome.19
Appropriate use of albumin solutions in hospitals is subject to guideline recommendations and control. Considering the latest publications on the tolerability of the synthetic colloids and

their risk of adverse reactions, recommendations for colloids’ use will increasingly differentiate between natural and artificial, in particular when volume resuscitation in intensive care and surgery is concerned. Current guidelines strongly recommend the inclusion of albumin solutions in the circulatory support in certain critically ill patients and in complications of cirrhosis of the liver. ●
