Primary Outcome Measures:
  • The congruity between palpatory technique and ultrasound lumbar evaluation [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 days ] [ Designated as safety issue: No ]
    The congruity between palpatory technique and ultrasound lumbar evaluation to identify the correct spinal space performing epidural analgesia


Secondary Outcome Measures:
  • Longitudinal and transverse ultrasound epidural space depth in obese and normal parturients [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 days ] [ Designated as safety issue: No ]
    Longitudinal and transverse ultrasound epidural space depth in obese and normal parturients will be measured and compared to the needle depth


Enrollment: 300
Study Start Date: October 2011
Study Completion Date: July 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts
normal subjects
parturients admitted to the labor ward who request epidural analgesia with BMI < 30
obese subjects
parturients admitted to the labor ward who request epidural analgesia with BMI > 30

Detailed Description:

This study has four specific aims:

  1. to evaluate congruity between palpatory technique and ultrasound lumbar evaluation to identify the correct spinal space;
  2. to compare between ultrasound evaluation and needle measure of skin-epidural space depth;
  3. to compare between longitudinal and transverse ultrasound epidural space depth in obese and normal parturients;
  4. to check the reduction of complications and failure rates of epidural analgesia with ultrasound assistance.
