Primary outcomePrimary: Epidural Pressure Sensitivity at Level of Epidural Insertion — 26.8; 26.8; 47.6 force (newtons/cm^2)
Summary
Historically, women who have chronic back pain after pregnancy have attributed the cause to the epidural procedure. While many studies have shown no greater incidence of generalized post-partum back pain in those who received an epidural, no studies have measured localized pressure sensitivity at the epidural insertion site. Short-term pressure sensitivity might limit patient's mobility and activities in the post-partum period. Understanding the factors that increase insertion site pressure sensitivity will allow the investigators to modify epidural placement technique in order to minimize this effect.
