Epidural Ropivacaine 0.75% vs Bupivacaine 0.5% for Surgical Anaesthesia, in Patients Undergoing Inguinal Hernioplasty

Opening of the article

Bupivacaine first synthesized in 1957 has acceptance in virtually every area of local anesthetic practice like intrathecal, epidural, nerve blocks as well as post-op pain relief. Ropivacaine is a long-acting regional anaesthetic that is structurally related to Bupivacaine. It is a pure S (-) enantiomer, unlike Bupivacaine, which is a racemate, developed for the purpose of reducing its potential toxicity and improving relative sensory and motor block profiles. Both drugs are being used for epidural anesthesia. The aim of this study is to compare the efficacy of epidural ropivacaine 0.75% versus bupivacaine 0.5% for surgical anaesthesia.
