Using Ultrasound to Study Respiratory Muscle Function in Critically Ill Patients
NCT03139695 · View on ClinicalTrials.gov ↗
Study Summary
Mechanical ventilation can be life saving strategy for patients with respiratory failure due to a variety of reasons. Once the underlying illness has resolved, intensive care doctors have to take a decision on when the patient is safe to get off the ventilator or be extubated. They use clinical assessment of the patient's ability to breathe spontaneously and make use of some breathing parameters to make the judgment. Most of the time, a patient can come off the ventilator and do well, but sometimes muscle weakness from sickness can affect the patient's ability to breathe adequately once ventilator support is discontinued. If that occurs, the patient may have to be put back on the ventilator and the physician will suggest some changes to help muscles get stronger. A simple, non-invasive test that can assess respiratory muscle state before taking patients off the ventilator to see if their muscles look healthy can help distinguish which patients may not be ready to be extubated. There are currently several tests available to assess muscle strength, in particular muscles that help in breathing like the intercostal muscles and diaphragm. The study will test the use of Ultrasonography (Ultrasound) as a non-invasive test to assess the muscles of respiration. This test will also help the investigators test physical therapies and interventions of mechanical ventilation that can help patients strengthen the muscles while waiting for extubation.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03139695
The ClinicalTrials.gov registry entry for NCT03139695 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 75 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Wake Forest University Health Sciences, which has 1,061 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Critical Illness appearing as the primary indexed condition, and to 1 intervention — of which Ultrasound is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03139695 reports 1 study location spanning 1 distinct geographic area — top geographies include North Carolina. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
