Brief summary

The aim of the study is to assess if there is a difference in ability to thread the epidural catheter from two different epidural pain management kits vendors

Detailed description

The aim of the study is to assess if there is a difference in ability to thread the epidural catheter from two different pain management kits. In order to improve patient care, if there is a difference in the time to thread epidurals with one kit over the other, we would like to use the kit with decreased time to thread in the future.
