Study summary

This study will be conducted as a pilot trial of the TransAeris system for the prevention and treatment of ventilator-induced diaphragm dysfunction (VIDD) in patients identified prior to surgery to be at greater risk of prolonged mechanical ventilation (PMV).

Read the detailed description

This pilot study is an open label observational study in adult open cardiac surgery patients. Eligible patients from whom informed consent is obtained and electrodes are successfully implanted are enrolled in the study. All subjects will be implanted with the TransLoc electrodes during their primary surgery. Following admission to the ICU, diaphragm EMG recording will begin and continue until TransAeris use begins or until discharge from the ICU. TransAeris stimulation therapy adjunctive to continued MV will begin 24 hours after leaving the operating room. TransAeris stimulator settings (stimulus intensity, stimulus frequency, and burst on/off) will be programmed to optimize diaphragm recruitment without compromising patient comfort.

When deemed ready by the physician, the subject will perform a spontaneous breathing trial (SBT). Diaphragm EMG will be recorded for the first 15 minutes of an SBT, when performed with study staff available, then TransAeris therapy will continue. If an SBT is not performed on a day or performed when study staff is not available, a diaphragm EMG will be recorded for 15 minutes and then TransAeris therapy will be resumed. If the subject fails the SBT or the physician determines the subject is inappropriate for extubation, TransAeris stimulation therapy will continue. Prior to leaving the ICU, diaphragm EMG will be recorded for 15 minutes and the TransLoc electrodes will be removed. Subjects that reach Day 30 after implantation will stop TransAeris therapy. Diaphragm EMG will be recorded for 15 minutes and the TransLoc electrodes will be removed prior to the end of Day 30.

Study arms

  • Experimental
    Treatment

    TransAeris stimulation therapy adjunctive to continued mechanical ventilation will begin 24 hours after leaving the operating room, if subject remains on mechanical ventilation. TransAeris stimulator settings (stimulus intensity, stimulus frequency, and burst on/off) will be programmed to optimize diaphragm recruitment without compromising patient comfort.

    Device: TransAeris System

Interventions

  • DeviceTransAeris System

    The TransAeris System is a temporary percutaneous intramuscular diaphragm stimulator intended for patients at risk of or on prolonged positive pressure mechanical ventilation. TransAeris is indicated for use in the prevention and treatment of ventilator-induced diaphragm dysfunction (VIDD).
