Background:
Medical simulation for the teaching of procedural skills to health-care providers is an effective method of instruction to improve safety, quality, and procedural efficiency. There are several commercially available simulators for lumbar puncture training; however, there is currently no model available for lumbar drain intrathecal catheter placement.
Methods:
A modular lumbar drain simulator was assembled with the use of a spine model, ballstical gel, and Penrose drain tubing to recreate the procedural steps and tactile feedback of a live lumbar drain insertion.
Results:
The assembled simulator demonstrated the ability to provide users with manual feeback of a "pop" sensation when intrathecal puncture was achieved with a 14 gauge Touhy needle, as well as spontaneous CSF flow. A silastic catheter was able to be inserted into the simulated subarachnoid space in the same manner as a live procedure.
Conclusions:
A high-fidelity lumbar drain simulator can be constructed in a cost-effective manner. We have detailed the materials and assembly of our successful design in order to provide a novel educational tool for procedural instruction and practice.

The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
