研究概览
简要总结
The study is a prospective, multi-center, randomized, controlled study using adaptive design to assess the evidence of safety and performance of the STIMIT Activator 1 System in the treatment of patients who have been mechanically ventilated for up to 7 days and are predicted to require additional minimum 48 hours of mechanical ventilation or longer.
详细描述
The objective of this clinical investigation is to evaluate the safety and effectiness of the STIMIT Activator 1 System in patients who are on invasive mechanical ventilation (MV) and thus are at risk of diaphragmatic dysfunction/atrophy.
The study is expected to enroll 40 participants at up to 8 centers focusing on North American sites (main focus USA, > 50% of study enrollment from US site). An interim analysis will be conducted after 30 participants have been enrolled and compelted their study follow-up to reconfirm sample size (adaptive design). Participants will be followed for up to 10 days or until they are successfully extubated (weaned) from mechanical ventilation, expire prior to extubation, or withdraw consent.

入选标准
- •Are 21 years or older, and,
- •Have recently been placed on invasive MV (enroll and randomized as soon as possible after intubation), and have received no more than 7 days of MV
- •Are predicted to remain on mechanical ventilation for an additional 48 hours or longer post randomization
排除标准
- •Patients that are actively treated with continuous infusion of neuromuscular blocking agents beyond the enrollment period.
- •Medical condition known to affect the phrenic nerve or respiratory muscles (examples of possible medical conditions that could affect the phrenic nerve provided in Annex 1 below).
- •Any patients with ICP probe.
- •Patients with metallic device implants or body penetrating metallic devices in the upper body area within 30cm (12inches) from the coils; known anatomy or devices in the neck area (e.g., ECMO cannulas in the neck area, collars or cranial appliances) that would interfere with headset placement or stimulation.
- •Any non-removable electrical / electronic device (device internal or external) that may be prone to interaction with, or interference from the STIMIT Activator, such as pacemakers, implantable defibrillators, implanted medication pumps, bio-stimulators, deep brain stimulators, implanted nerve stimulator, deep brain stimulators or cochlear device implants.
- •Cardiogenic or septic shock with ongoing severe hemodynamic instability that cannot be stabilized within the enrollment period.
- •Physician thinks that the patient will not tolerate initial installation of the STIMIT respiratory sensor.
- •Anticipating withdrawal of life support and/or shift to palliation as the goal of care.
- •Known to be pregnant.
- •Participating in another clinical trial studying an experimental Intervention that could affect the study primary outcome.
- •Patients whose ultrasonographic assessment of right-sided diaphragmatic thickness would be too difficult (e.g. local subcutaneous emphysema surrounding the zone of apposition, large dressings in the zone of apposition that cannot be removed).
- •Patients with neck condition that would not allow placing the coils on the neck (e.g. open wounds that cannot be covered, skin at risk for burns).
- •Patients with significant spontaneous efforts (P0.1 < - 2) that would not be at risk for diaphragmatic atrophy/ dysfunction.
结局指标
主要结局
