['In burn patients, microvascular permeability is increased. It is difficult to decide the time to administer albumin because it may induce pulmonary edema in the re-filling period. One report shows that microalbuminuria is correlated with endothelial injury and systemic microvascular permeability.', 'We measured urinary albumin/creatinine ratio (ACR) in 4 burn patients for 48 hours after injury.', 'In all patients, ACR was elevated in the early period after injury. Moreover, ACR in 2 severe burn patients with burn total body area of over 30% was above the normal range.'] Do [ The clinical course of microalbumiuria in 4 burn patients ]?
