Is biolectrical impedance analysis a tool at bedside, during heat waves to assist geriatricians with discriminative diagnosis of hypertonic dehydration?

Objectives: To assess BIA data given by Analycor 3 and some bio-impedance equations to assist geriatricians with discriminative diagnosis of hypertonic dehydration, during heat waves.

Design: Prospective study: a dehydrated patients group has been compared with a randomised control group.

Setting: The study was carried out in a French geriatric department, in the Emile Roux geriatric hospital.
