title: The evidence for small-volume resuscitation with hyperoncotic albumin in critical illness.
abstract: Small-volume resuscitation of critically ill patients with hyperoncotic albumin offers a number of theoretical advantages, such as increasing intravascular volume in excess of the volume of fluid administered and reducing interstitial edema. Whilst iso-oncotic albumin has been shown to be equi-effective to isotonic saline for the resuscitation of critically ill patients without associated traumatic brain injury, the efficacy of hyperoncotic albumin for resuscitation has not been evaluated in large-scale randomized-controlled trials. Overall, the evidence for resuscitation with hyper-oncotic albumin is limited by studies of poor methodological quality with heterogenous study populations and control regimens. There is marginal qualitative evidence of improvements in surrogate outcomes in disparate patient populations, but no evidence of any survival benefit associated with resuscitation with hyperoncotic albumin. Given the lack of evidence and clinical uncertainty about the efficacy of hyperoncotic albumin, a large-scale randomized-controlled trial is required to determine its role in the acute resuscitation of hypovolemic or hypoalbuminemic critically ill patients.
