A Comparison of Continuous Thoracic Epidural Analgesia with Bupivacaine Versus Bupivacaine and Dexmedetomidine for Pain Control in Patients with Multiple Rib Fractures.
چکیده
The control of pain in traumatic patients with chest injury leading to rib fracture is one of the primary goals in traumatic patients. The efficacy of the thoracic epidural approach in comparison with other approaches for relieving post-thoracotomy pain is unknown. The goal of the present study was to compare thoracic epidural analgesia with bupivacaine alone and in combination with dexmedetomidine in patients with multiple rib fractures.64 traumatic patients with multiple rib fractures were selected and randomly assigned to two similar groups. For pain relief, a thoracic epidural catheter was inserted to infuse bupivacaine alone or the combination of bupivacaine and dexmedetomidine. Then, we recorded and analyzed pain scores and ABG changes.Based on the results, the two approaches could result in proper analgesia, but analgesia with the combination of bupivacaine and dexmedetomidine was significantly improved compared to bupivacaine alone (P < 0.05). In addition, ABG of patients significantly changed when the combination of bupivacaine and dexmedetomidine was used within 2 to 4 days (P < 0.05).The results of the present study showed that epidural infusion of a combination of bupivacaine and dexmedetomidine could provide better control of rib fracture pain in traumatic patients, and is a proper alternative for bupivacaine alone.
