Objective Evaluation of a New Epidural Simulator by the CompuFlo^® Epidural Instrument

Figure 1

After having removed the inner length of plastic of a commercially available epidural simulator (P61, 3B Scientific), we inserted in its place a modified solid rigid polyurethane foam spinal column model. This way the vertebral arch and the other possible bony parts which may be encountered during needle insertion were present into the model in a life-like dimension and structure.
