Clinical Trial Summary

Regional anaesthesia is the performance of spinal, epidural or peripheral nerve blocks to allow patients to undergo surgery awake and to provide post-operative pain relief. Anaesthetists inject local anaesthetic using specialist needles close to nerves to prevent transmission of pain. Hand-held ultrasound is often used by anaesthetists to direct these needles to the correct position i.e. close to, but not in the nerve itself. If the needle is not adequately seen using the hand-held ultrasound it may pierce the nerve causing permanent nerve damage and significant patient harm.

Within the time and resource constraints of postgraduate medical training, it would be advantageous to optimise expertise acquisition of practical skills with a cheap, self-directed educational intervention. Therefore, the aim of this study is to determine whether gaze training is associated with improved performance of an ultrasound-guided needle task. The investigators hypothesise that improved gaze control will translate to better technical performance of an ultrasound-guided regional anaesthesia task.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in Task completion time	Time taken to finish needling task	Undertaken during ultrasound assessment 1 (before training intervention) and during ultrasound assessment 2 (which will occur 10 minutes after the training intervention was undertaken). Each assessment will be 15 minutes in duration.
Other	Change in Fixation durations	The total duration in seconds during the task that the participant spends engaging fixation visual behaviour in pre-defined areas of interest during the needling task	Undertaken during ultrasound assessment 1 (before training intervention) and during ultrasound assessment 2 (which will occur 10 minutes after the training intervention was undertaken). Each assessment will be 15 minutes in duration.
Primary	Change in Composite Error Score	Objective error scoring of performance at needling task	Undertaken during ultrasound assessment 1 (before training intervention) and during ultrasound assessment 2 (which will occur 10 minutes after the training intervention was undertaken). Each assessment will be 15 minutes in duration.
Secondary	Change in Global Rating Scale	Objective performance scoring of needling task, scored from 0-35, higher scores indicating better task performance.	Undertaken during ultrasound assessment 1 (before training intervention) and during ultrasound assessment 2 (which will occur 10 minutes after the training intervention). Each assessment will be 15 minutes in duration.
