Detailed data will be continuously collected in "real time" during fluid resuscitation over the 1st 48 hours following a burn injury. Data collection during this phase will be done prospectively, hour-by-hour, by the bedside nurse caring for the patient. Primarily this data collection will involve recording of resuscitation fluid volumes, urinary output, vital signs (heart rate and blood pressure), and use of vasopressors and inotropes. Outcome data (organ function, need for mechanical ventilation, hospital length of stay, and survival) will be collected at various time points during the subjects' acute care stay.
