DESCRIPTION (provided by applicant): This project will evaluate the clinical efficacy and cost savings benefits from use of an endotracheal tube (ETT) position and patency monitoring system through a prospective, randomized, controlled trial conducted at m ultiple clinical centers. The two years, two phase study will enroll up to 270 subjects that include neonates, children, and adults who require intubation for extended ventilatory assistance. The system operation is based on an acoustic pulse-echo techniqu e that non-invasively probes ETTs with sound and uses the returning echoes to determine the tube's position within the patient and provide quantitative information regarding tube patency. Phase I will verify safety and feasibility in approximately 50 subje cts by programming the device to continuously collect ETT position and function data while the subject is mechanically ventilated, but blinding the research team to these data. Normal standard of care procedures will be used to maintain proper ETT functi on (e.g. routine chest x-rays to confirm ETT position, suctioning). Measurable results from these procedures will be compared to the data recorded on the device to determine consistency. Adverse events will be analyzed to determine if any were device relat ed. If the results meet the safety and feasibility endpoints, Phase II will be initiated. Phase II will consist of a prospective, 1:1 randomized study of approximately 220 subjects in which the device will be used as a primary means to monitoring ETT locat ion and function. Device data will be collected in addition to the standard of care measures performed on each subject. The primary hypothesis being investigated in this study is that use of this device will decrease the overall respiratory adverse event r ate associated with mechanical ventilation. Secondarily, the data will be analyzed to determine if this device reduces adverse events associated with ETT position or function and predicts ETT-related adverse events prior to their occurrence. SonarMed's int elligent endotracheal tube (ETT) monitoring system has the potential to establish a new paradigm in the standard of care for airway management. It will enable clinicians to move from the current reactive approach that provides corrective action only in res ponse to indirect indications of ETT complications (patient in respiratory distress), towards a more proactive methodology where immediate notification of high risk ETT conditions (ETT on verge of extubation) can be used to anticipate and thereby prevent a dverse events.
