| Abstract: | The use of high thoracic epidurals for post-thoracotomy pain relief in 156 patients is reviewed. Analgesia was maintained with a continuous infusion of a local anaesthetic, bupivaca?ne 0.5% 40 ml, mixed with a narcotic, fentanyl 10 ml (perfusion rate between 3 and 7 ml/h). There was successful analgesia in 92%, with efficient ventilation, effective cough, no respiratory distress and only 8 cases of fibroaspiration. Only two significant respiratory complications occurred, due to incorrect management of the peridural route: the analgesic mixture was too concentrated and was injected by bolus instead of by continuous infusion. Other complications occurred, 8 cases of nausea or pruritus, 4 hallucinations, 10 cases of urinary retention lasting more than 24 h, 14 superior limb palsies and 22 Horner's oculopapillary syndrome. All of these complications were minor, easy to manage, and resolved after stopping peridural infusion. In conclusion, peridural analgesia is highly effective and improves the atmosphere in post-thoracotomy wards. |
