About this study

Official title: Percutaneous Electrical Phrenic Nerve Stimulation (PEPNS) System Feasibility Study

The purpose of this feasibility study is to evaluate the safety and performance of the PEPNS System in patients that need to be mechanically ventilated for at least 48 hours and up to 7 days in the Intensive Care Unit (ICU).

Read the detailed description

Mechanical ventilation is a life saving technology but can also cause damage to the lungs and diaphragm such as ventilator induced diaphragmatic dysfunction (VIDD). Research has shown that after being on mandatory mechanical ventilation and sedation the diaphragm begins to atrophy within as little as 18 hours. The PEPNS System consists of a console and disposable lead and will be used to stimulate the patient's diaphragm to contract in synchrony with the inspiratory cycle of the ventilator. The proprietary phrenic nerve to diaphragm stimulation (pdSTIM) Lead incorporates multipolar electrodes that align with the left and right phrenic nerves in order to stimulate the nerves to the diaphragm. This feasibility trial will investigate the safety and performance of the PEPNS System as a therapy by stimulating the diaphragm over a 48 hour period to facilitate weaning from the mechanical ventilator. The patient population includes those need to be mechanically ventilated for at least 48 hours and up to 7 days in the ICU.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PEPNS SystemDevice

    Also called pdSTIM

    PEPNS System therapy will be delivered periodically up to 48 hours or less if patient is no longer being mechanically ventilated.

Study groups in NCT03559933
Study groupRoleWhat they receive
PEPNS SystemExperimentalThe pdSTIM lead will be temporarily inserted near the right and left phrenic nerves and connected to the PEPNS system console in order to stimulate the phrenic nerves and activate the diaphragm on the patients until extubated/removed from mechanical ventilation or until 48 hours has elapsed, whichever comes first.
Receives: Device: PEPNS System

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Capture of Left and/or Right Phrenic Nerve

    Capture of the Left and/or Right Phrenic Nerve > 80% with an output parameter of < 10.5 volts. Capture was defined as diaphragmatic movement as a direct consequence of electrical phrenic nerve stimulation. Capture for this analysis was defined as synchrony of the stimulated breath with the output parameter <10.5 volts and Work of Breath between 0.2 and 2.0 Joules/L. Synchrony was achieved if the lag time between start of inspiration and start of stimulation was less than 88 ms. The proportion of successful capture was analyzed using a generalized linear mixed model accounting for subject and stimulation within subject as random effects, and the outcome of capture was yes/no based on whether the stimulation captures the diaphragm with multiple observations per subject.

    Measured: Up to 48 hours

  2. Percent of Breaths Within Work of Breathing Range

    Work of Breathing (WOB) kept between 0.2 and 2.0 joules/L for 80% of stimulated breaths. Outcome is measured as a percentage of stimulated breaths that had a WOB between 0.2 joules/L and 2 joules/L and the performance goal was 80%.

    Measured: Up to 48 hours

Secondary outcomes (3)
  1. Safe and Successful Lead Placement

    The percentage of patients who receive safe and successful placement of the multipolar lead in the left and right phrenic nerve utilizing ultrasound guidance will be determined.

    Measured: Up to 48 hours

  2. Phrenic Nerve Stimulation Effectiveness

    Phrenic nerve stimulation in synchrony with Mechanical Ventilation breaths will be measured to verify that is occurs with inspiration.

    Measured: Up to 48 hours

  3. Serious Device/Procedure Related Adverse Events

    The percentage of patients who experience one or more serious device/procedure-related adverse events during the study will be reported.

    Measured: Up to 48 hours

What does the primary outcome measure?

Percent Capture of Left and/or Right Phrenic Nerve (time frame: Up to 48 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03559933, which also lists 2 linked publications.
