Abstract text

A metabolite monitoring system comprising a microdialysis probe including a semi-permeable membrane and a probe flow path passing from an inlet through a sensing volume adjacent to said semi-permeable membrane to an outlet, a fluid delivery device for delivering dialysate to said inlet; and a metabolite monitoring system associated with said outlet for monitoring a concentration of at least one metabolite in said dialysate from said microdialysis probe, wherein said fluid delivery device is configured to deliver a pulsed flow of said dialysate to said inlet.
