Widespread use of neuraxial ultrasound may be limited by technical expertise, as blocks are usually performed using body surface landmarks to guide the epidural needle insertion point. A wireless handheld ultrasound (US) device with pattern recognition software programmed to calculate depth to the epidural space and identify bony landmarks has been developed (Accuro, Rivanna Medical, Charlottesville, VA) (AU). In the present study, the authors evaluated the accuracy of this device for neuraxial depth and landmark assessment.
