Clinical Trial Summary

Ventilator-induced diaphragmatic dysfunction is a common issue in critically ill patients. Muscle stimulation has shown to have beneficial effects in muscle groups on the extremities. A non-invasive way to stimulate the diaphragm would be the electromagnetic stimulation but it is currently unclear if that is feasible. In this proof-of-concept trial the primary aim is to show that it is possible to induce a diaphragmatic contraction in critically ill ICU patients via an external electromagnetic stimulation of the phrenic nerve, leading to an inspiration (i) with a sufficient tidal volume (3-6 ml/kg ideal body weight) and (ii) with verifiable muscular diaphragmatic contraction through ultrasound imaging.


Clinical Trial Description

During the time of first spontaneous breathing trial 60% of mechanically ventilated patients present with diaphragmatic weakness or also know as ventilator-induced diaphragmatic dysfunction (VIDD). The damage to the diaphragm in terms of muscle atrophy has been shown as early as 12 hours after initiation of mechanical ventilation. Recently, a correlation between diaphragmatic atrophy and mortality could be established. Induction of diaphragmatic contractions via stimulation of the phrenic nerve would be a possible method to prevent or treat VIDD. A possible modality would be the non-invasive electromagnetic stimulation but feasibility has not been established. In this proof-of-concept trial the primary aim is to show that it is possible to induce a diaphragmatic contraction in critically ill ICU patients via an external electromagnetic stimulation of the phrenic nerve, leading to an inspiration (i) with a sufficient tidal volume (3-6 ml/kg ideal body weight) and (ii) with verifiable muscular diaphragmatic contraction through ultrasound imaging. ;
