A Prospective Cohort Study to Evaluate the Safety, Efficacy, and Usability of the EpiZact Device

The purpose of the study is to learn if use of the EpiZact device decreases the number of wet taps that occur when epidurals are placed. The EpiZact device has a technology that automatically stops the epidural needle when it enters the epidural space. In theory, this should decrease the likelihood of a wet tap. The standard epidural to treat labor pain does not have this capability. The study device may cause fewer wet taps than the standard epidural. All study participants will receive an epidural to treat labor pain with the EpiZact device. Results will be compared with patients receiving epidurals around the same time without the EpiZact device. If a participant's screening questions show that they can take part in the study, and the participant chooses to be a part of the study, medical records from OHSU or other facilities may be reviewed. Information reviewed may include treatment history, medications, surgeries, allergies, scans, and lab results. The participant will then receive an epidural with the EpiZact device. After the epidural is placed, the participant will be asked a few questions to determine how well the epidural is working and if a complication occurred. The questions are expected to take less than 5 minutes to answer. Participants will also be called 1 week after receiving an epidural to determine if a complication occurred. This call is expected to last less than 5 minutes.
