Case ReportsContinuous brachial plexus block at the cervical level using a posterior approach in the management of neuropathic cancer pain.
Neuropathic cancer pain due to tumor growth near the brachial plexus is often treated with a combination of nonsteroidal anti-inflammatory drugs, tricyclic antidepressants, anticonvulsants, and oral or transdermal opioids. We propose placement of a catheter along the brachial plexus using a posterior approach for patients not responding to the above-mentioned treatment. ⋯ Continuous brachial plexus block should be considered in patients with severe neuropathic cancer pain in the arm and shoulder. To achieve sufficient pain relief for prolonged periods of time, a catheter was inserted to block the brachial plexus using a posterior approach. This technique may be a valuable alternative to the interscalene approach because of the improved fixation of the catheter in the muscle sheet of the trapezius, splenius cervicus, and levator scapulae muscles, and the decreased likelihood of catheter dislodgment during neck movements.

Randomized Controlled Trial Clinical TrialA paravenous approach for the saphenous nerve block.
This study assesses a paravenous approach for saphenous nerve block at approximately the level of the tibial tuberosity, and compares it with the conventional technique of blind subcutaneous infiltration between the tibial tuberosity and the gastrocnemius muscle. ⋯ The saphenous nerve can be blocked effectively by a paravenous approach using only 5 mL of local anesthetic solution. This approach is advantageous because of its easily identifiable landmark.
