Overview
Brief Summary
Sufentanil-ropivacaine combination is commonly used for epidural labor anesthesia, but is associated with some adverse events. Dexmedetomidine is a high selective alpha2-adrenoceptor agonist. Mounting evidences show that dexmedetomidine-ropivacaine combination can also be used effectively for epidural labor analgesia. This pilot trial is designed to compare the effect of dexmedetomidine-ropivacaine combination versus sufentanil-ropivacaine combination on neonatal outcomes when used for epidural labor analgesia, and to test the feasibility of a future large randomized trial.
Detailed Description
Sufentanil combined with ropivacaine is commonly used for epidural labor anesthesia. However, this combination is associated with some adverse events including increased risk of neonatal depression. Dexmedetomidine is a high selective alpha2-adrenoceptor agonist and possesses opioid-sparing and analgesic effects when used in combination with local anesthetics. Recently published data suggest that dexmedetomidine-ropivacaine combination can effectively relieve labor pain. We suppose that, when compared with traditional sufentanil-ropivacaine combination, the dexmedetomidine-ropivacaine combination used for epidural labor analgesia may reduce sufentanil-related adverse neonatal outcomes. The purpose of this pilot trial is to compare the effect of dexmedetomidine-ropivacaine combination versus sufentanil-ropivacaine combination used for epidural labor analgesia on neonatal outcomes, and also to test the feasibility of a future large randomized trial.
