Ropivacaine Versus Bupivacaine as a Local Anesthetic for Skin Infiltration in Preparation for Epidural Anesthesia in Orthopaedic Procedures of Lower Limb

摘要

Ropivacaine may have advantages over bupivacaine in epidural analgesia for Orthopaedic procedures. Intravenous ropivacaine have been shown to yield less cardiac and central nervous system side effects than bupivacaine (1), and ropivacaine for epidural analgesia for Orthopaedic procedures is found to produce less motor block than bupivacaine (2, 3). Furthermore, the pain associated with intramuscular injection of ropivacaine was found to be significantly less painful than bupivacaine despite similar pH of the solutions (4). The aim of this study to compare ropivacaine with bupivacaine for local infiltration in preparation for Orthopaedic procedure of Lower limb.
