【 摘 要 】

Acute opioid withdrawal has been described after interruption of prolonged intrathecal opioids but hasnot been reported after discontinuation of epidural fentanyl. A 60 year old male underwent a Whippleprocedure and T7 thoracic epidural was placed for postoperative pain management using bupivacaine0.1% with fentanyl 2 μg/ml started at a rate of 6 ml/hr. On the third postoperative day the epidural wasdiscontinued. The patient developed acute opioid withdrawal after four hours of discontinuation, to berelieved by intravenous tramadol and fentanyl. The epidural infusion was resumed and tapered downgradually over a period of 12 hrs with no recurrence of withdrawal symptoms.
