Epidural analgesia can be a valuable method of pain control in a variety of situations. It can facilitate early mobilisation and enhance recovery from surgery. This article describes the physiology of epidural pain relief and the nurse's role in monitoring patients effectively, recognising complications and minimising risk

An injection of local anaesthetic and/or opioids into the epidural space is an effective method of providing pain relief during the postoperative period. Epidural block allows analgesic solution to be delivered to a specific area within the epidural space. The solution affects the appropriate nerve roots (1) and dermatomal nerves supplying the area of the wound, giving a segmental band of analgesia.
