"Vibwife One" a New Medical Device to Support Delivering Women in Their Mobilization

November 13, 2018 updated by: University Hospital, Basel, Switzerland

A Single - Centre Safety Study About the Safety, Practicability and Acceptance of "Vibwife One", a New Medical Device to Support Delivering Women in Their Mobilization

"Vibwife One" was developed to support the mobilization of the delivering women during the labor process. It consists of a mattress that fits on existing delivery beds. Different movements, adjustable in pace and intensity can be chosen to mobilize women in labor.

Although existing evidence is rare, some literature and historical reports have shown a positive impact of active mobilization during labor.

At time of rising epidural anesthesia rate, "Vibwife One" could be an interesting way to active mobilize those women to support the physiological birth process.

So far, the device has not yet been applied in delivering women. The investigators carry out a first safety study to assess the safety, to evaluate the comfort and the practicability for delivering women and medical staff of this new medical device.

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.

Detailed Description

The medical device will be used according to its market authorization. Because it will be used for the first time in pregnant women, the following three step application procedure has been determined:

  • First five pregnant women use the device for 10 minutes. Each of them in a position and module proposed by the midwife with the agreement of the woman.
  • Next 10 pregnant women use the device for 20 minutes. Again, position and module according to the decision of the midwife with the agreement of the woman.
  • All the remaining pregnant women (35) use the device for 30 minutes. Position and module according to the decision of the midwife with the agreement of the woman.

During the intervention period, position and module might be changed once if required.

After the inclusion of all the 50 participants, each position and module has to be tested.

There will be a safety review board consisting of one physician, one midwife and a clinical expert midwife meeting after each group of pregnant women having used the device, evaluating the safety criteria according to predefined Adverse Device Effects and Adverse Events.

The medical device will be used according to its market authorization.

Because it will be used for the first time in pregnant women, the following three step application procedure has been determined:

  • First five pregnant women use the device for 10 minutes. Each of them in a position and module proposed by the midwife with the agreement of the woman.

Device: Vibwife One

Vibwife One is a powered rotation bed intended to be used to assist in active mobilization of delivering women. "Vibwife One" imitates manual mobilization and position techniques. It is integrated in the mattress and fixed to the pelvis area of the birthing bed. "Vibwife One" can be used, when manual mobilization and position techniques are deemed appropriate.

The device with all its functions is controlled over a remote control.

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
Measure Description
Time Frame
Safety measured by number of Adverse Events and Adverse Device Effects
Time Frame: During intervention and until 30min. after end of intervention
The Primary outcome is safety of the pregnant woman and the child using "Vibwife One" in the first stage of Labor. It will be evaluated according to predefined Adverse Events and Adverse Device Effects.
During intervention and until 30min. after end of intervention

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
Measure Description
Time Frame
Pain intensity
Time Frame: VAS before, during and after end of the intervention, intervention lasting up to 30 min.
Pain intensity is measured by a discrete Visual Analogue Scale (VAS) from 0-10, 0 indicating no pain until 10 indicating greatest pain
VAS before, during and after end of the intervention, intervention lasting up to 30 min.
Preferences measured by questionnaire
Time Frame: within 30 minutes after end of the intervention, intervention lasting up to 30 min.
Women's preferences regarding the medical device will be measured by a questionnaire with a 4-issue Likert scale; Likert scaling is a bipolar scaling method, measuring either positive or negative response to a statement. The responses in this study might be 1.Strongly disagree, 2.Disagree, 3.Agree 4. Strongly agree, answers ranging from 1 point (strongly disagree) to 4 points (strongly agree). Low amount of points represent a better outcome.
within 30 minutes after end of the intervention, intervention lasting up to 30 min.
