Enrolled subjects will be randomly assigned to either the Colloid Group or the Crystalloid Group. Randomization will be based on an intent-to-treat basis. In order to ensure that the two groups have comparable injury severity at baseline, randomization will be block- stratified based on age (18-50 and \> 50 years), burn size (25-50% and \> 50% TBSA), and presence of inhalation injury confirmed by bronchoscopy (present or absent). In the Colloid Group resuscitation starts with LR and then 5% albumin will be introduced between 8 and 12 hours post burn in a ratio of 1/3 albumin to 2/3 LR. In the Crystalloid Group resuscitation is with LR only. Each group will have their study fluid maintained for the 1st 48 hours post burn and study fluids in each group will be identically titrated to the urinary output.
