This study will review chart data collected from our obstetrical clinic, OSU Obstetrics and Gynecology, as well as OSU Medical Center records. We will first search the hospital's records for patients admitted with the diagnosis of active labor. These charts will be examined for inclusion/exclusion criteria and entered into the study if they are eligible (as later defined). Once these charts have been obtained, we will then search their corresponding clinic chart for the defined parameters of our study.
