NCT06660784

Brief 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. 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. 2.Exploring the potential key molecular mechanisms of NO treatment on the occurrence and development of VIDD after ECMO assisted mechanical ventilation.

Outcome Measures

Primary Outcomes (1)

  • Diaphragm function

    Continuous POCUS monitoring of diaphragm function during mechanical ventilation, including diaphragm thickness, diaphragm thickening fraction, diaphragm excursion, etc

    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.

Secondary Outcomes (2)

  • Inflammatory cytokines

    The fixed time point on the 1st, 2nd, 3rd, 4th, 5th, 6th and 7th day.

  • Oxidative stress markers

    The fixed time point on the 1st, 2nd, 3rd, 4th, 5th, 6th and 7th day.

Interventions

Depending on the indication, the subjects 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.
