An Inexpensive Adult Lumbar Puncture Task-Trainer with Simulated Cerebrospinal Fluid

Simulation is beneficial in achieving competence and success in the performance of procedures. Unfortunately, costs associated with purchasing simulation equipment is a significant barrier to implement this training. The objective was to create a model for lumbar puncture that allowed performance of the procedure using anatomic landmarks, ability to obtain cerebrospinal fluid, and measure opening pressure.

A model was built using several readily available and low-cost items and was iterated based on feedback. The task trainer was used as part of multiple educational sessions and simulations with different groups of learners, including residents and medical students.

A reusable task trainer was built to simulate the performance of a lumbar puncture that met our objective of using anatomic landmarks with the ability to collect simulated cerebrospinal fluid and measure opening pressure. The model had a low fixed cost for the initial investment (less than $75) and minimal variable costs.

An innovative and easy to make low-cost model is presented as an option to use for lumbar puncture training at institutions with limited resources. This do-it-yourself model is unique in providing learners the opportunity to obtain cerebrospinal fluid and measure opening pressure. The model is easy to transport and can be implemented as part of educational sessions and simulation scenarios.
