Background and Aims Ultrasonography has paved the way for development and precision in needle placement, not only with a range of nerve blocks but to aid neuraxial procedures in regional anaesthesia. A survey of anaesthetic practices in Wessex illustrated more than 90% respondents had never used ultrasound for neuraxial blockade(1) with more than 90% unaware of any courses that taught ultrasound techniques to identify the epidural space(1). We organised a regional course on the use of ultrasound to aid neuraxial procedures.
Methods The programme consisted of initial lectures covering the foundations of ultrasonography and current evidence-based practice with a live demonstration on scanning the lumbar spine. Following which, the candidates were split into smaller groups with hands-on scanning on live models of varying body mass index (BMI). Pre- and post-course questionnaires were completed.
Results The pre-course questionnaire highlighted that over 50% of candidates did not routinely use ultrasound for neuraxial procedures and more than 80% reported ‘amateur’ or ‘no level of experience’ with using ultrasound. In contrast, the post-course questionnaire highlighted their experience of hands-on scanning during the course with over 65% increase in confidence in using ultrasound in their future practice.
Conclusions Pre-procedural ultrasound imaging provides information about the accurate intervertebral level for puncture, optimal needle insertion point, and depth of needle advancement for a successful neuraxial block(2). The questionnaires emphasise a need for more frequent courses on ultrasonography for neuraxial procedures to improve confidence in scanning especially challenging scenarios such as the high BMI obstetric patient; perhaps even recommending to medical specialties too.
