The Role of Lung and Diaphragm Ultrasonography in Predicting Clinical Progression in Hypoxemic Respiratory Failure

November 22, 2024 updated by: Simge Evren

The Role of Lung and Diaphragm Ultrasonography in Predicting Clinical Progression in Patients Receiving High-Flow Nasal Oxygen and Non-Invasive Mechanical Ventilation Support for Hypoxemic Respiratory Failure

The goal of this observational study is to evaluate whether the risk of intubation in patients with hypoxemic respiratory failure who were monitored in the intensive care unit and received non-invasive mechanical ventilation and high-flow nasal oxygen treatment could be predicted using lung and diaphragm ultrasound.

The main question it aims to answer is:

Can lung and diaphragm ultrasound predict the risk of intubation in patients with hypoxemic respiratory failure?

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.

Detailed Description

Between January 1, 2024, and May 1, 2024, the diaphragm thickness fraction, excursion, LUS score, ROX index, and the LUSS/ROX index ratio were evaluated using lung and diaphragm ultrasound in 91 patients admitted to the intensive care unit with a diagnosis of hypoxemic respiratory failure. These evaluations were performed at the 6th, 12th, 24th, and 48th hours of their ICU stay, and during intubation if the decision for intubation was made

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

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
Lung and diaphragm ultrasound evaluation for risk of intubation
Time Frame: 48 hours
Lung and diaphragm ultrasound can predict risk of intubation
48 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.
Outcome Measure
Measure Description
Time Frame
ROX index evaluation for risk of intubation
Time Frame: 48 hours
The Respiratory Rate-Oxygenation Index can predict the risk of intubation Higher score means lower risk

Study Major Dates

Study Start (Actual)

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.
January 1, 2024

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.
