Primary objective: To compare the decrease in systolic blood pressure between hydration and venous contention when switching to a standing position. Hypothesis in that hydration is better than venous contention.
Secondary objective: To evaluate the effect of hydration on lowering systolic blood pressure during the passage standing in elderly patients with orthostatic hypotension.
Inclusion criteria: Patient aged over 75 years old with orthostatic hypotension proved to 1 and / or 3 min

- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Crossover Assignment
- Primary Purpose: Prevention
- Masking: None (Open Label)
- Study Primary Completion Date: May 2016
Day 0: confirmation of the orthostatic hypotension, without prevented measures
Two groups randomized :
- Group 1: First day (day 1), Orthostatic Hypotension test after hydration by three large glasses of clear liquid (33cl). Second day (day 2), Orthostatic Hypotension test with venous contention in the morning.
- Group 2: First day (day 1), Orthostatic Hypotension test after implementation of venous contention in the morning. Second day (day 2), Orthostatic Hypotension after hydration by three large glasses of clear liquid (33cl).
- Other: Hydration
- Hydratation the first day in the arm 1 Hydration the second day in the arm 2
- Other: Venous contention
- Venous contention the second day in the arm 1 Venous contention the first day in the arm 2
Arms, Groups and Cohorts
- Active Comparator: Hydration
- •Group 1: First day, Orthostatic Hypotension test after hydration by three large glasses of clear liquid (33cl). Second day, Orthostatic Hypotension test with venous contention in the morning.
- Active Comparator: Venous contention
- •Group 2: First day, Orthostatic Hypotension test after implementation of venous contention in the morning. Second day, Orthostatic Hypotension test after hydration by three large glasses of clear liquid (33cl).
Clinical Trial Outcome Measures
- difference in systolic blood pressure between sitting and standing at 1 and 3 minutes between hypotension test with hydration and hypotension test with venous contention
- Time Frame: during 3 days: day 0, day 1, day 2
- difference in systolic blood pressure between sitting and standing at 1 and 3 minutes between hypotension test with hydration and hypotension test without prevention
- Time Frame: during 3 days: at day 0, day 1, day 2
