EpiFaith Resident Learning Curve Trial

This study aims to evaluate the impact of the EpiFaith® syringe on the learning curve of anesthesia residents for the labor epidural technique. Anesthesia residents with prior experience placing \< 5 labor epidurals will be enrolled. Their performance of 20 sequential labor epidural placements with either standard technique with a beveled glass syringe or the EpiFaith® syringe will be observed. Successful epidural placement over time with sequential epidural placement attempts will be measured between groups. The primary outcome will be rate of successful epidural placement. Success will be defined as a composite of 4 criteria: maximum 3 attempts for placement; no need to re-site at a different level; no required intervention by the supervising attending anesthesiologist; and adequate analgesia with a visual analog score (VAS) \<3 at 30 minutes. We hypothesize that use of the EpiFa
