The efficiency of pulsed radiofrequency application on L5 and l6 dorsal roots in rabbits developing neuropathic pain.
Injury of a peripheral nerve may lead to neuropathic pain, a form of chronic pain that does not respond to traditional pain therapies. The aim of this study was to investigate the effect of pulsed radiofrequency (PRF) applied to the L5 and L6 dorsal roots on the neuropathic pain that develops after sciatic nerve injury in rabbits. ⋯ The hyperalgesia that develops as a result of neuropathic pain in rabbits was observed to be reduced by PRF application.

Randomized Controlled Trial Comparative StudyA prospective, randomized comparison between single- and double-injection ultrasound-guided infraclavicular brachial plexus block.
This prospective, randomized, observer-blinded study compared single- and double-injection ultrasound-guided infraclavicular brachial plexus block for upper extremity surgery. ⋯ The double-injection ultrasound-guided infraclavicular block provides no significant advantages compared with its single-injection counterpart.

Randomized Controlled TrialLong-lasting analgesic effects of intraoperative thoracic epidural with bupivacaine for liver resection.
Continuous epidural analgesia may be considered in liver resection but is often avoided because of possible coagulopathies and the risk of epidural hematoma in the postoperative period. On the other hand, there is no coagulation defect during the surgery. Effective prevention of postoperative pain may require continuous sensory ablation throughout the surgery event. ⋯ Intraoperative thoracic epidural infusion of bupivacaine, added to intrathecal morphine, decreased postoperative morphine consumption with better pain relief compared with the placebo.
