Primary outcomePrimary: Time for Epidural Placement — 9.0; 6.2 minutes
Summary
This study will address the utility of ultrasound in the placement of an epidural catheter in severely obese parturients. Identification of midline can often be difficult using the standard method of palpation in obese patients. The Investigator will determine if the use of ultrasound decreases the amount of time and number of attempts required to place the epidural.
