Neuraxial Ultrasound Device Study (NCT06281249)
๐ฉบ Plain-English Summary (8th-Grade Level)
The aim of the study is to develop a device that can eliminate failed neuraxial placements in challenging patients.The study will attempt to improve safety and efficacy of neuraxial anesthesia with high precision real-time needle visualization through automated real-time needle guidance at the bedside with an experimental device (Accuro 3S). Investigators will verify the clinical workflow for utilizing the Accuro 3S during epidural and spinal procedures and validation of needle visualization while using the device as well as anatomical guidance provided by the device during spinal imaging.The underlying bone imaging enhancement algorithms were introduced in the commercially available FDA approved Accuro. The Accuro 3S will be used to establish needle insertion point and trajectory, after which the clinician will use standard of care methods to advance the needle such as the loss of resistance method.
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (3 items) and avoid the listed exclusions (8 items).
