  Purpose

This is a data base building project on the use of pre-procedure ultrasound for the performance of labor epidural pain relief and spinal anesthesia for cesarean deliveries. Data collection includes ultrasound measured depth, actual needle depth, angle of ultrasound probe, actual needle angle, success rates, patient height and weight, number of attempts needed to place the epidural needle or spinal needle. Currently we are looking at the agreement between ultrasound determined depth of the epidural space or intrathecal space with actual needle depth.

Primary Outcome Measures:
  • Correlation of Ultrasound vs Needle Depth [ Time Frame: Beginning of ultrasound exam to end of ultrasound exam: average 5 min ] [ Designated as safety issue: No ]
    The ultrasound measured depth taken via oblique sagittal views and transverse views of the epidural space for epidural analgesia or intrathecal space for spinal anesthesia will be correlated with actual needle depth


Secondary Outcome Measures:
  • Attempt Number [ Time Frame: Beginning of placement of epidural or spinal needle to end of placement: average 10 min ] [ Designated as safety issue: No ]
    The number of needle placement attemtps: an attempt is defined as a separate needle placement The number of needle redirects: a redirect is defined at the need for changing the angle of needle direction at each separate needle attempt


Estimated Enrollment: 400
Study Start Date: January 2010
Estimated Study Completion Date: January 2012
Estimated Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Pregnant Women
Pregnant women receiving labor epidural analgesia or spinal anesthesia for cesarean delivery
 Device: Ultrasound
Preprocedure ultrasound examination of the spine

Detailed Description:

All patients presenting in labor or are having a cesarean delivery are eligible except: patients who are under age 18, have contraindications to regional anesthesia, in advanced labor, having emergency conditions and/or unable to understand the consent process.

  • Data collected include:
  • Ultrasound depth in transverse and oblique sagittal views
  • Actual needle depth
  • Level of placement
  • Number of separate needle placements
  • Number of needle redirects
  • Angle of probe
  • Angle of needle
  • Total number of attempts
  • Pt height
  • Pt weight
  • Pt BMI
  • Pt age
  • Pt gravity/parity
  • Pt co-morbidities, e.g. pre-eclampsia
  • Procedure performed
  • Operator (Attending, CA-1, CA-2, CA-3, CRNA)

What is currently being examined is the correlation between ultrasound depth of the target area vs actual needle depth
