A retrospective case-control study was conducted. Patients who admitted to the burn ward and needed fluid resuscitation during the period of January 2011 to December 2018 in our unit were identified. Patients were divided into two groups according to the severity of burns, the patients with a 20%<TBSA≤50% constituted the moderate and severe burn group, the patients with a TBSA>50% constituted the severest burn group, and then the patients who used albumin for resuscitation constituted the albumin group, the patients who did not use albumin constituted the control group. The primary outcome was mortality, and the secondary outcomes included hospital stay, ventilator supporting, fluid use, and complications.
