An attempt is being made to see if by injecting a set volume of sterile saline into the epidural space during the treatment of labor pain with a combined spinal/epidural (CSE) increases the amount of pain relief obtained and makes the labor analgesia lasts longer. Subjects are in the study from the time their CSE is placed until they request additional pain medication from the spinal dose of numbing medicine wearing off.

Condition Intervention
Labor Pain
Other: Sterile normal saline 0 mls
Other: 15 mls sterile normal saline

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
Official Title: Effect of Epidural Saline on Duration and Spread of Subsequent Spinal Analgesia/Anesthesia Using a CSE Technique

Further study details as provided by Wake Forest University Health Sciences:

Primary Outcome Measures:
  • Highest sensory blockade level to pinprick and to cold [ Time Frame: <20 minutes ]
    onset of analgesia to recession of analgesia

Secondary Outcome Measures:
  • time to onset of analgesia [ Time Frame: <20 minutes ]
    CSE dose until pain is <3

  • Duration of analgesia (time to request additional analgesia) [ Time Frame: approximately 1-2 hours ]
    from pain relief <3 to time analgesia receding

Enrollment: 60
Study Start Date: August 2009
Study Completion Date: September 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: 0 mls saline injected
Other: Sterile normal saline 0 mls
at time of epidural needle placement there will not be any saline injected into the epidural space prior to placement of the spinal needle to administer the CSE dose of standard analgesic medications. Instead a pause will be done as by the investigator to maintain blind for the assessor.
Active Comparator: 15 mls saline
Other: 15 mls sterile normal saline
After the epidural needle is placed, 15 mls of sterile normal saline will be injected into the epidural space, then the spinal needle will be placed to administer the CSE dose of standard analgesic medications.
