Trial summary

In this study, 20 hypercapnic COPD patients will perform two constant workrate endurance cycle tests. One test will be while using non-invasive Ventilation (NIV) support, one without in a randomized cross-over design. The aim is to measure, whether NIV is able to change peripheral and respiratory muscle oxygenation. Read more about this study

About this study

Official title: The Effect of Non-invasive Ventilation on the Oxygenation of Peripheral Muscle Tissue, Cardiovascular System and Exercise Capacity in Hypercapnic COPD Patients

In this study, 20 hypercapnic COPD patients will perform two constant workrate endurance cycle tests. One test will be while using non-invasive Ventilation (NIV) support, one without in a randomized cross-over design. The aim is to measure, whether NIV is able to change peripheral and respiratory muscle oxygenation.

Read the detailed description

In this study patients will perform one incremental work rate test to obtain peak work rate. On the following days two constant work rate cycle endurance tests (CWRT) will be performed at 60% of Peak work rate using a randomised cross-over design. Between the two CWRTs there will be one hour of recovery time in between.

One of the CWRTs will be performed with the support of non-invasive Ventilation (NIV), the other one without. Respiratory and cardiovascular parameters will be observed through transcutaneous measurement of CO2 (Sentec device) and near-infrared spectroscopy devices.

The purpose of this study is, to examine whether the use of NIV not only decreases patients dyspnoea, but also has positive effects on the patients cardiovascular System, exercise capacity and muscle oxygenation. The investigators will examine the tissue oxygen saturation in the 7th intercostal space (reflecting a respiratory muscle) and on the M. vastus lateralis of the leg during both CWRTs. With the Support of NIV, it is expected to see a change in the oxygenation towards a better perfusion of the leg muscle, due to a facilitation of the work of breathing. This may result in a later onset of leg fatigue and an increased exercise capacity of the patients. To have an equivalent workload all parameters will be compared during isotime.

To conclude, aim of this study is to record the interplay of Oxygenation and Perfusion between the Intercostal muscles and the peripheral leg muscle during exercise. The investigators hypothesize, that the use of NIV may change the oxygenation in favour of the leg muscle through relieving the respiratory muscles.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. cycle endurance time

    time patient ist able to cycle at 60% of his peak work rate

    Measured: maximum 20 minutes

Secondary outcomes (8)
  1. Borg scale of dyspnoea

    In the beginning and in the end of the constant work rate tests patients will be asked to rate their current level of dyspnoea on the modified Borg scale from 0 to 10

    Measured: 30 minutes

  2. Borg scale of leg fatigue

    In the beginning and in the end of the constant work rate tests patients will be asked to rate their current Level of leg fatigue on the modified Borg scale from 0 to 10

    Measured: 30 minutes

  3. Oxygen saturation

    Measurement of the oxygen saturation during the constant work rate tests

    Measured: 30 minutes

  4. Heart rate

    Measurement of the heart rate during the constant work rate tests using a pulse oximeter

    Measured: 30 minutes

  5. Arterial blood pressure

    Riva-Rocci measurement of the arterial blood pressure before and in the end of the constant work rate tests

    Measured: 30 minutes

  6. arterial carbondioxide partial pressure

    recording of the transcutaneously measured arterial carbondioxide partial pressure using Sentec technology during the constant work rate tests

    Measured: 30 minutes

  7. Tissue Saturation Index

    the near infrared technology delivers the Tissue Saturation Index throughout the constant work rate test

    Measured: 30 minutes

  8. total hemoglobin

    the near infrared technology delivers the Tissue Saturation Index throughout the constant work rate test

    Measured: 30 minutes

Questions about this trial

What is this clinical trial studying?

A study testing non-invasive ventilation (NIV) in people with COPD and Hypercapnia, run by Schön Klinik Berchtesgadener Land at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

cycle endurance time (time frame: maximum 20 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02877290, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Nov 2017.
