Clinical Trial Summary

Controlled mechanical ventilation may lead to the development of diaphragm muscle atrophy, which is associated with weakness and adverse clinical outcome. Therefore, it seems reasonable to switch to partially supported ventilator modes as soon as possible. However, in patients with high respiratory drive, the application of partially supported modes may result in high lung distending pressures and diaphragm injury.

Recently, the investigators published a study that demonstrated that a low dose of neuromuscular blocking agents (NMBA) facilitates lung-protective ventilation and maintains diaphragm activity in intensive care unit (ICU) patients. That study was conducted in a small (N=10), selected group of patients and partial neuromuscular blockade was applied for only 2 hours (proof-of-concept study). Therefore, further research has to be done before this strategy can be applied in clinical practice.

The primary goal is to investigate the feasibility and safety of prolonged (24 hours) partial neuromuscular blockade in patients with high respiratory drive in partially supported mode. The secondary goals are to evaluate the effect of this strategy diaphragm function, lung injury, hemodynamics and systemic inflammation.
