Orthopedic Surgeon Safety Lower CV and CNS toxicity Overall better side effect profile Safety is where ropivacaine has a clear advantage. It is widely known in our institution that bupivacaine has more cardiovascular toxicity. Anesthesiologist MOA Ropivacaine has been shown to have shorter depth and duration of motor block compared to bupivacaine Clinical Flexibility Considered more clinically versatile by physicians Approved for use in children For all these reasons, a long acting bupivacaine is a hit but a long acting ropivacaine would be a home run .
