Transcutaneous Partial Oxygen and Carbon Dioxide Pressures Compared With Blood Gas Values (OxiVenT)

February 4, 2019 updated by: Vera Bernet, MD

Agreement of Transcutaneous Partial Oxygen and Carbon Dioxide Pressure With Arterial and Capillary Blood Gas Values. A Single Centre Prospective Non-randomized Trial in Critically Ill Neonates.

Partial blood oxygen and carbon dioxide pressures obtained in critical ill neonates by transcutaneous sensors will be compared to respective values obtained by medically indicated arterial and capillary blood gas analyses. The influence of blood withdrawal method, sensor operational temperature and application time, presence of cyanotic heart malformations and/or intra or extra cardiac right to left shunt, vasoactive drugs, elevated non-conjugated bilirubin, and skin and soft tissue oedema, skin colour and perfusion conditions will be elucidated as well as sensor's safety. Study duration will be 48 hours with sensors applied and additional 4 hours of further surveillance for thermal injury.

Study Overview

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

No older than 2 months (CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
EXPERIMENTAL: All included patients
All included patients will undergo the intervention of transcutaneous sensor placement
Device: Sentec (SenTec) Digital Monitoring System with OxiVenT Sensor
The sensor will be attached to four anatomical positions (thoracic left and right; abdominal left and right), starting with the left thoracic position followed by 4-hourly clockwise position rotation. In case of severe oedema, the ear lobes will be used as anatomical measurement sites and changes to the contralateral ear lobe are made every 4 hours.

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
Bias and precision of the transcutaneous oxygen and carbon dioxide measurements
Time Frame: 52 hours
Agreement of transcutaneous measurements with capillary and arterial blood gas values at two operational sensor temperatures (42 and 43°C).
52 hours

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.
