Mechanism of Nitric Oxide on Ventilator-induced Diaphragm Dysfunction with Extracorporeal Membrane Lung Assistance

China80 participantsStarted 2024-01-16

Plain-language summary

The goal of this clinical trial is to explore the effect of NO treatment on diaphragm function after mechanical ventilation with ECMO assistance. We expect to enroll a total of 80 patients who will receive mechanical ventilation and mechanical ventilation combined with ECMO treatment. Depending on the indication, they will be given NO treatment or not. In ECMO assisted mechanical ventilation + NO treatment group, the subjects will be randomly assigned to NO treatment via ventilator or membrane oxygenator. The main questions it aims to answer are: 1. Observing the influences and potential therapeutic effects of different NO insertion methods through ventilator or membrane oxygenator on the occurrence and development of ventilator-induced diaphragm (VIDD) dysfunction during ECMO assisted mechanical ventilation. 2. Exploring the potential key molecular mechanisms of NO treatment on the occurrence and development of VIDD after ECMO assisted mechanical ventilation.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Diaphragm function

Timeframe: We starts POCUS within 1 hour (1h) after mechanical ventilation, and continuously monitoring the diaphragm function at 6h, 12h, 24h, 48h, 72h, 96h, 120h, 144h and 168h respectively. POCUS will be terminated if the patient dies.
