Trial summary

There are two cases in which the cross-sectional area of the tracheal catheter balloon does not match the cross-sectional area of the patient's airway. If the area of the tracheal catheter balloon is smaller than the cross-sectional area of the patient's airway, the pressure in the balloon reaches 30 cmH2O, and the… Read more about this study

About this study

There are two cases in which the cross-sectional area of the tracheal catheter balloon does not match the cross-sectional area of the patient's airway. If the area of the tracheal catheter balloon is smaller than the cross-sectional area of the patient's airway, the pressure in the balloon reaches 30 cmH2O, and the airway cannot be completely sealed; This will increase the risk of VAP. If the area of the tracheal catheter balloon is significantly larger than the cross-sectional area of the patient's airway, and the pressure in the balloon reaches 30 cmH2O, the airway cannot be effectively sealed; The formation of wrinkles around the airbag also increases the risk of VAP in patients. Therefore, the purpose of this study is to build a risk model of airway leakage of patients' endotracheal tubes, which provides an accurate and objective assessment tool for medical staff, so that medical staff can select the endotracheal tubes purposefully and with emphasis from the beginning of the patients' endotracheal tubes, and reduce the airway leakage or airway mucosal damage of the endotracheal tubes.

Read the detailed description

Admission number, department, name, gender, height, and weight are obtained through the hospital's electronic medical record management system。 Tidal volume (set Tidal volume), airway peak pressure (real-time data on the ventilator screen), data collection is synchronized with the minimum cuff pressure measurement when the airway is closed.

Being tested
Construction and evaluation of airway leakage risk model of patients with endotracheal tube

What participants receive

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

  • Construction and evaluation of airway leakage risk model of patients with endotracheal tubeOther

    1. Conduct statistical analysis on general information, respiratory data, tracheal catheter data, and cross-sectional area of the patient's airway to clarify the current status of airway leakage and related influencing factors.
    2. Based on multivariate logistic regression, a line chart prediction model for predicting the risk of airway leakage in patients with tracheal catheters is constructed. The clinical efficacy of the prediction model is evaluated by using the area under the ROC curve, the Calibration scatter plot, and the DCA decision line, respectively, to assess its discrimination, calibration, and clinical practicality.

What is being measured

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

  1. Patient airway area

    Firstly, confirm the front position of the tracheal catheter through chest X-ray, and then manually sketch the area of interest along the outer wall of the airway using Computed Tomography to calculate the area.

    Measured: Within 1 year

Secondary outcomes (1)
  1. Measure the minimum cuff pressure

    The specific method is as follows: the patient takes a 30 ° semi recumbent position, puts a Stethoscope on the throat of the patient's trachea, inflates air into the trachea tube cuff until the air leakage sound just disappears, at this time, the value displayed by the cuff pressure gauge is the minimum cuff pressure when the airway is closed

    Measured: 1min

Questions about this trial

What is this clinical trial studying?

An observational study of Mechanical Ventilation, run by Affiliated Hospital of Nantong University at 1 site in China.

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 1 inclusion and 1 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 27 Jun 2023. 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 China. 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?

Patient airway area (time frame: Within 1 year). 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 NCT05921656, 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 27 Jun 2023.
