About this study

Official title: Clinical Study of Diaphragmatic Ultrasound to Predict the Therapeutic Effect of High Flow Oxygen Therapy in Mild and Moderate Acute Hypoxic Respiratory Failure

Follow-up was conducted for every patient requiring high-flow nasal cannula oxygen therapy in district 1 of the Intensive Care Department of Chenzhou NO.1 People's Hospital. Patients who met the inclusion criteria but did not meet the exclusion criteria were included for observation. Respiratory parameters, diaphragmatic activity, and variation rate of diaphragmatic thickness were recorded at the beginning of high-flow nasal cannula oxygen therapy, 1 hour after treatment, 3 hours after treatment, 6 hours after treatment, 9 hours after treatment, and 12 hours after treatment. Throughout the procedure, a panel of experts assessed whether the patient needed endotracheal intubation; If yes, the study was terminated; if no, high-flow nasal cannula oxygen therapy was continued, and observation and evaluation were continued until the end point of the study (12 hours after treatment). If patients or their family members do not want to continue to participate in the study during the study, they will be considered as withdrawal. If patients suffer from sudden malignant arrhythmia or cardiac arrest during the study, resulting in death or transfer to other hospitals or other departments during the study, patients will be excluded. Data from dropped and excluded patients were not included in the final statistical analysis. After the data of 269 patients were collected, the study was concluded, and the results and conclusions were derived by statistical analysis.

Diaphragm ultrasound

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Diaphragm ultrasoundDiagnostic test

    Respiratory parameters, diaphragmatic activity, and variation rate of diaphragmatic thickness were recorded at the beginning of high-flow nasal cannula oxygen therapy, 1 hour after treatment, 3 hours after treatment, 6 hours after treatment, 9 hours after treatment, and 12 hours after treatment.

What is being measured

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

  1. Thickness and thickening fraction of Diaphragm

    Diaphragm thickness and thickening fraction (TFdi) were measured using a high-frequency linear array probe at the midaxillary line. TFdi = (diaphragm thickness at the end of inspirations - diaphragm thickness at the end of expirations)/diaphragm thickness at the end of expirations × 100%

    Measured: 0-12 hours

  2. Diaphragmatic excursion

    Diaphragmatic excursion was measured using a low-frequency curved array (" abdomen ") probe located directly below the costal arch on the midline of the clavicle.

    Measured: 0-12 hours

  3. Respiratory rate

    Respiratory rate of the patient after high-flow nasal oxygen therapy

    Measured: 0-12 hours

  4. Incidence of tracheal intubation

    After the patient uses high-flow nasal oxygen therapy, the panel determine whether the patient needs to undergo tracheal intubation according to the indicators such as symptoms and signs of the patient.

    Measured: 0-12 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Hypoxic Respiratory Failure, run by Xingui Dai.

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 6 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 28 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact Feng Yang, Master (15886524007, 17546639@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Thickness and thickening fraction of Diaphragm (time frame: 0-12 hours). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Mar 2024.
