This is a prospective, non-interventional, observational study of consecutive burn patients admitted to 20 selected burn centers in North America. Primarily, data collection will be continuous "real-time" documentation of fluid infusion rates, vital signs and laboratory values of patients receiving fluid resuscitation during the first 48 hours following burn injury. All aspects of the resuscitation and all investigations performed will be according to the participating center's regular protocol, as this is purely an observational and non-interventional study. Further data collection on outcomes (organ function, ventilation duration, length of stay, and survival) will be collected at 72h, 96 h, and at hospital discharge.
