Rehydration therapy is critical for management of dehydration. The goal of replacement therapy is to replenish deficits in water and electrolytes lost, while maintance to maintain homeostasis.

●Phases of rehydration – Fluid management consists of two phases: replacement and maintenance.

Replacement – Treatment begins with the replacement phase, which continues until all signs and symptoms of volume depletion have resolved and the patient has urinated; ideally, this is achieved during the first four hours of treatment.

Maintenance – The maintenance phase counters ongoing losses of water and electrolytes; this phase continues until diarrhea and other signs and symptoms of illness have resolved.
