Effect of Immersion, Performed Under the Conditions of Obstetrical Dilatation Bath, on Diuresis and Hemodynamic Variables in Young Women (IMMERSION)

October 5, 2017 updated by: University Hospital, Strasbourg, France

Like in the full immersion, studied in the context of diving, immersion in water causes a cascade of events with hemodynamic and hormonal consequences.

First, immersion leads to a relative hypervolemia by venous redistribution and then 40-60 minutes later, hypovolemia by stimulating diuresis.

Dilatation bath is helpful in relieving moderate pain the first stage of obstetrical labor.

However, when the labor progresses, the dilatation bath is no longer sufficient and epidural analgesia remains the only effective method to control pain.

Used before the realization of an epidural analgesia, dilatation bath could affect blood volume and thus worsen the hemodynamic consequences of the sympathetic block that is linked to the installation of sensory block of the epidural analgesia in the parturient (severe prolonged maternal hypotension that can cause a decrease of the placental perfusion and fetal distress).

Before beginning a study in pregnant women, it seems essential to study the hemodynamic consequences of the dilatation bath in a comparable population of volunteers healthy young women and out of the obstetrical context.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Enrollment (Actual)

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

18 years to 45 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

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.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 15, 2015

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
