True about epidural opioids are all except?
Epidural opiate administration is routinely used by many anaesthesiologists involved in obstetric anaesthesia. Epiduralinjection of a local anaesthetic combined with an opioid generates a more rapid onset of more profound analgesia with little motor blockade. Thus pain relief lasts longer than after either drug alone. Ref: KD Tripathi 8th ed.
