Title: Optimal concentration of epidural fentanyl in bupivacaine 0.1% after thoracotomy. Author: Tan CN, Guha A, Scawn ND, Pennefather SH, Russell GN. Journal: Br J Anaesth; 2004 May; 92(5):670-4. PubMed ID: 15033892. Abstract: BACKGROUND: The aim of this prospective, double-blind, randomized controlled trial was to investigate the analgesic and adverse effects of three commonly used concentrations of thoracic epidural fentanyl with bupivacaine in patients undergoing thoracotomy for lung resection. METHODS: We studied 99 patients who were randomized to receive fentanyl 2 microg ml(-1) (group 2), fentanyl 5 microg ml(-1) (group 5) and fentanyl 10 microg ml(-1) (group 10) in bupivacaine 0.1% via a thoracic epidural. Postoperatively, pain on coughing was assessed using a visual analogue scale (VAS) and an observer verbal rating score (OVRS) at 2, 8, 16 and 24 h. At the same times, sedation, pruritus and nausea were assessed. RESULTS: Of 29, 28 and 32 patients who completed the study in groups 2, 5 and 10 respectively, there was no significant difference in baseline characteristics between the three groups. The number of patients with episodes of unsatisfactory pain, i.e. VAS scores >30 mm and OVRS >1, at each of the four assessments postoperatively was significantly (P<0.01) higher in group 2 than in groups 5 and 10. In group 10, 16 patients had sedation scores >1 compared with 10 each in groups 2 and 5. In addition, 19 patients in group 10 experienced pruritus compared with 12 each, in groups 2 and 5. These differences were not significant. Nausea was not significantly different between the three groups. CONCLUSION: We conclude that thoracic epidural fentanyl 5 microg ml(-1) with bupivacaine 0.1% provides the optimum balance between pain relief and side effects following thoracotomy.[Abstract] [Full Text] [Related] [New Search]
