Efficacy of bupivacaine and ropivacaine for postoperative analgesia in continuous epidural infusion in lower limb surgeries under combined spinal-epidural analgesia

ABSTRACT

Background: Bupivacaine has been traditionally used as a local anesthetic of choice for regional anesthesia and analgesia. Ropivacaine has been marketed in our country with a claim of better motor profile, better safety profile and an equivalent analgesic profile when used in epidurals for postoperative pain. This study aims to compare both drugs as an epidural infusion in terms of safety, analgesic efficacy by NRS score and patient satisfaction score and motor blockade by modified bromage score in postoperative period
