Background. In this study, we describe a custom-made new epidural simulator, created by modifying the inner structure of a commercially available one, in the attempt to make it adequately realistic. To validate and evaluate the realism of our device, we used the Computerized Epidural Instrument CompuFlo. Method. The Compuflo CompuFlo curves obtained from 64 experiments on the epidural simulator were compared to 64 curves obtained from a previous human study, from consecutive laboring parturients requesting epidural analgesia. Results. Epidural simulator and human pressure curves were very similar. There was a significant difference between the drop of pressure due to false and true loss of resistance (LOR) in both the groups. Discussion. Our simulator can realistically reproduce the anatomical layers the needle must pass as demonstrated by the similarity between the simulator and human pressure curves and the small differences of pressure values recorded. CompuFlo may be used as an objective tool to create and assess and compare objectively the epidural task trainers.
