Condition labor pain
Treatments tetracaine, bupivacaine
Sponsor Wake Forest University
Start date August 2009
End date December 2011
Trial size 46 participants
Trial identifier NCT01005459, IRB 9824


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.
