Study on the Measurement Method of the Left Diaphragm (LD)

23 april 2026 uppdaterad av: Shanghai Zhongshan Hospital

To Study the Consistency of Multiple Measurement Methods of Left Diaphragm Mobility in Critically Ill Patients

This study intends to use ultrasound to measure the bilateral diaphragmatic ultrasound indicators in critically ill patients, focusing on the left diaphragm, and to explore the consistency and reliability among various ultrasound indicators to evaluate the diaphragmatic mobility

Beskrivning

Inclusion Criteria:

①Adult patients (≥18 years old) of both sexes;
- In invasive group, intubation or tracheotomy was changed to 5L/min T-tube or tracheotomy mask oxygen inhalation;
  - Patients in non-invasive group were treated with mask oxygen 5L/min;
    - agree to participate in the trial and sign the informed consent;

Exclusion Criteria:

①The diaphragm ultrasound operation site was too large to obtain images.
- Diaphragmatic ultrasound images could not be obtained in any section;
  - The ultrasound image quality of any section was poor;
    - the presence of phrenic nerve injury/paralysis ⑤ pregnant women; ⑥ Neuromuscular diseases such as ALS and myasthenia gravis affect the evaluation of spontaneous breathing ⑦ Patients deemed by the investigator to be ineligible.

Vad mäter studien?

Primära resultatmått

Resultatmått	Åtgärdsbeskrivning	Tidsram
Consistency of diaphragmatic mobility measurements between the standard and modified positions on the left side. Tidsram: Measurements were performed 5 minutes after all patients were switched to conventional oxygen therapy at 5 L/min for the first time, once breathing had stabilized.	The main purpose is to verify the consistency of the two methods, Measurements were performed after switching patients in the invasive group (intubated patients to T-piece oxygen at 5 L/min and tracheostomized patients to face mask oxygen at 5 L/min following weaning), and patients in the non-invasive group (those receiving non-invasive ventilation or high-flow oxygen therapy) to conventional face mask oxygen at 5 L/min.	Measurements were performed 5 minutes after all patients were switched to conventional oxygen therapy at 5 L/min for the first time, once breathing had stabilized.

Consistency of diaphragmatic excursion measurements between the standard position and the other four positions on the left side. Tidsram: Measurements were performed 5 minutes after all patients were switched to conventional oxygen therapy at 5 L/min for the first time, once breathing had stabilized.
