NCT01062776

Brief Summary

  1. 1.The distribution and elimination of infusion fluids can be studied by volume kinetics, a mathematical method based on serial analysis of the blood hemoglobin concentration.
  2. 2.The hypothesis of the present study is that the elimination of infused fluid is retarded in the presence of dehydration, and that volume kinetics would therefore be capable of detecting dehydration in human subjects.
  3. 3.We induce dehydration by injection graded doses of furosemide (a diuretic drug) in healthy volunteers and the kinetics of an infusion of crystalloid fluid is compared to when the same volunteer receives the same fluid without being in a dehydrated state.

Outcome Measures

Primary Outcomes (1)

  • As determined by volume kinetics, a healthy human male eliminates infused crystalloid fluid more slowly when being in the dehydrated state as compared to when being normohydrated.

    December 2010

Secondary Outcomes (1)

  • The volume kinetics of an infusion fluid can/can not be measured as accurately by non-invasive monitoring as by invasive monitoring of the blood hemoglobin concentration

    May 2010 (preliminary analysis)

Study Arms (4)

5 ml/kg of fluid, no dehydration

PLACEBO COMPARATOR

Volunteers receive an intravenous infusion of acetated Ringers solution over 15 min without preceding deliberate dehydration with furosemide.

Biological: Placebo

10 ml/kg of fluid, no dehydration
