The primary objective of this study is to compare the effectiveness of epidural waveform analysis (EWA) with fluoroscopic guidance for confirmation of successful epidural placement. In this study, participants will undergo both EWA and fluoroscopy. EWA involves measuring the pressure in the epidural space once accessed and determining whether or not a waveform that corresponds with the participant's heart rate is present. The pressure measuring apparatus is the same that is used for direct pressure monitoring elsewhere in the body (i.e. invasive arterial catheters or intracranial pressure monitoring).

Positive Predictive Value and Negative Predictive Value of epidural waveform analysis to predict epidural access compared with fluoroscopic guidance
Timeframe: Time of enrollment through completion of epidural placement. Epidural placement occurs on study day 1 and is generally completed within 2 hours of study enrollment.
