BACKGROUNDEpidural analgesia is considered by many as 'gold standard' of analgesic technique for postoperative analgesia after lower limb as well as abdominal surgeries. Epidural analgesia has the ability to maintain continuous analgesia after placement of an epidural catheter with the analgesic drug thus making it suitable for continuous postoperative pain relief and early ambulation. Epidural opiates in combination with local anaesthetics are commonly used for postoperative analgesia with several lines of evidence indicate that opiates administered through the epidural route are safe with proven benefits such as good pain relief, less pain during movement, better mental status, fewer complication. Even though bupivacaine, the ideal local anaesthetic and has similar pharmacological profile with ropivacaine, but which cardiac safety margin is lower than ropivacaine due to its Senantiomer.
