The investigators hypothesis is that spinal tetracaine with fentanyl and epinephrine used for CSE labor analgesia volume will last a significantly longer period of time that that of spinal bupivacaine with fentanyl. After informed consent is obtained for the study, subjects meeting criteria when analgesia is requested will be randomized to receive a combined spinal-epidural containing either tetracaine 2 mg with fentanyl and epinephrine or bupivacaine 2 mg with fentanyl and epinephrine.

Condition Intervention Phase
Labor Pain Drug: Tetracaine Drug: Bupivacaine Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Comparison of Spinal Tetracaine With Fentanyl and Epinephrine Versus Bupivacaine With Fentanyl and Epinephrine for Combined Spinal Epidural Labor Analgesia

Primary Outcome Measures:
  • Spinal Analgesic Duration [ Time Frame: 1-2 hrs ]
    duration of time in minutes from the time the combined spinal epidural is placed until the participant requests additional analgesia; at that time the epidural was dosed and study participation was complete

Enrollment: 46
Study Start Date: August 2009
Study Completion Date: December 12, 2011
Primary Completion Date: December 12, 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: tetracaine 2mg Drug: Tetracaine
Tetracaine 2mg will be combined with Fentanyl 20 mcg and Epinephrine 50 mcg to treat labor pain.
Active Comparator: Bupivacaine 2 mg Drug: Bupivacaine
Bupivacaine 2 mg combined with fentanyl 20 mcg and Epinephrine 50 mcg will be used to treat labor pain.
