 Informed consent will be obtained by one of the licensed physician investigators at the earliest opportunity when the subject arrives on the labor suite and following contact with their provider. While the timing between subject arrival and request for neuraxial analgesia can be variable, in subjects who present in early labor at less than 5 cm cervial dilation, there is often several hours available for a subject to consider 1 whether they desire a central neuraxial technique during labor, and 2 whether they would be willing to participate in this study.
