Evaluation of the Effect of Hydration About Orthostatic Hypotension in the Elderly. Difference With Venous Compression (CHHO)

October 1, 2015 updated by: Central Hospital, Nancy, France

Evaluation of the Effect of Hydration About Orthostatic Hypotension in the Elderly. Difference With Venous Compression. A Randomized Controlled Crossover Trial.

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 Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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).

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

75 years and older (OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Exclusion Criteria:

  • bedridden patient or without possibility of verticalization

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
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
during 3 days: day 0, day 1, day 2

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
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
during 3 days: at day 0, day 1, day 2
