Brief Summary

The use of Ultrasound Guided Regional Anaesthesia (USRA) has increased over the last decade. Theoretically, ultrasound imaging may increase efficacy and safety by allowing visualization of the needle pathway and local anaesthetic spread around the nerve. In addition to knowledge of anatomy and general principles of ultrasonography, USRA requires learning new skills such as image interpretation, needle-beam alignment, and needle trajectory tracking. The hand-eye coordination required during needle advancement requires practice to master because the needle must be properly aligned with the ultrasound probe in order to maintain the needle path in the beam at all times. Adding to the difficulty, hand and needle movements can occur in three axes, but an ultrasound image is seen in only two dimensions. Since the ability to acquire the necessary skills to perform USRA is subjective and not yet validated, it is difficult to recommend a single, effective training pathway. Currently, the only method of supervised training before performing an USRA procedure on an actual patient involves practicing needle insertion in a phantom or cadaver. Studies assessing the impact of learning using these methods are lacking. It is possible that some practitioners may choose alternative one-off learning methods. Such methods are not standardized and are thus difficult to evaluate.

Outcome Measures

Primary Outcomes (1)

• Needle image accuracy score difference

  The experimental group was allowed to practice the same pre-test task using the same ultrasound machine and phantom model. On a single computer screen, they were able to visualise their hand and needle movements along with the position of the ultrasound probe. The control group was allowed to practice the same pre-test task using the same ultrasound machine and phantom model but without the added visual aid. Both groups were allowed to practice their pre-test tasks for a maximum of 30 minutes

  30 minutes
