A microcomputer-based fluid infusion system for the resuscitation of burn patients.

Abstract

Fluid replacement therapy, essential in the treatment of burn patients, continues to be a difficult clinical responsibility. Inherent variability of individual patient response to conventional burn fluid formulas and the practical limitations involved in manually adjusting fluid infusion rates on a continuous basis combine to hamper proper fluid administration. A microcomputer-based fluid infusion, data acquisition, and control (FIDAC) system has been developed to optimize fluid volume restoration and maintenance in the clinical treatment of burn and trauma patients. The FIDAC system provides real-time measurement of infused fluid and urine output, the display and routine recording of fluid balance parameters, and closed-loop control of fluid resuscitation. The system has been evaluated through a series of animal tests and is currently in clinical use at the University of Utah Medical Center Intermountain Burn Unit.
