Background and Aims Regional anaesthesia is the future of sustainability and forms a mandatory part of the new 2021 anaesthetic trainee curriculum. Simulation provides vital training, and gelatine phantom models enhance needling skills to minimise complications in clinical practice. A meta-analysis of the effectiveness of the loci method as a mnemonic device has proved to aid memory recall. We aimed to determine if there was subjective improvement of needling technique among trainees with the use of part-task gelatine-based models along with the use of the acronym ”PSV PRO” as an aid-memoire to facilitate a systematised approach for needling.
Methods We created gelatine phantom models with target artefacts including grapes and cotton threads. Candidates practiced needling techniques on phantom models with the laminate acronym beside. We used anonymous questionnaire to be filled by the trainees and collected data. We then run 2 teaching sessions which were attended by the trainees of broad range of grades to broaden the power of this study.
Results There was >30% improvement in probe handling and needling technique confidence. 28% of trainees became extremely confident after the course. Pre course candidates percentage who said they were confident or very confident combined was 64% of the total number of candidates. However, post course the percentage of trainees who were confident or more increased to >90%.
Conclusions PSV PRO resulted in the subjective improvement of needling technique among trainees during this simulation-based exercise. The homemade jelly phantom models were excellent for purpose. PSV PRO should be used in real life teaching and high-definition simulation.
