Randomized Controlled Trial
Combined Infraclavicular-Suprascapular Nerve Blocks Compared With Interscalene Block for Arthroscopic Rotator Cuff Repair: A Prospective, Randomized, Double-blind, and Comparative Clinical Trial.
The gold standard postoperative analgesia protocol for arthroscopic rotator cuff repair procedures is the interscalene block (ISB), which prevents the significant consequences of phrenic nerve block associated with hemidiaphragmatic paralysis (HDP). The infraclavicular brachial plexus block (BPB) combined with the suprascapular nerve block (SSNB) had the same analgesic efficacy as the infraclavicular BPB alone, with no effect on respiration. ⋯ The employment of the costoclavicular block in combination with the suprascapular block may provide a comparable analgesic potency to the sole use of the standard ISB with no HDP.

Output Current and Efficacy of Pulsed Radiofrequency of the Lumbar Dorsal Root Ganglion in Patients With Lumbar Radiculopathy: A Prospective, Double-blind, Randomized Pilot Study.
Lumbar radicular pain (LRP) is a common but challenging clinical symptom. Pulsed radiofrequency (PRF), a neuromodulation technique that uses short pulses of radiofrequency current, is effective in treating various pain disorders. However, few studies have been conducted on the effects of PRF and its modifying parameters. ⋯ Lower output currents during PRF application to the lumbar DRG were associated with greater analgesic effects in patients who did not respond to therapeutic TFESI.

Randomized Controlled Trial
Comparison of the Low Back Pain Relief and Spread Level After Upper and Lower Lumbar Erector Spinae Plane Block.
The erector spinae plane block (ESPB), which was introduced to manage the thoracic pain, is an ultrasound-guided technique that is relatively easy, less invasive, and safer. In spite of its technical ease and safety of ESPB, few studies have explored the analgesic efficacy and the exact spread level of injected local anesthetics. ⋯ Both the L2 and L4 ESPB groups demonstrated a significant reduction in low back pain and improvement in disability. The L2 ESPB group demonstrated a significantly increased spread level compared to the L4 ESPB group.

Effect of Radiofrequency on Dorsal Root Ganglion Versus Transforaminal Steroids Injection on Tumor Necrosis Factor-Alpha Level in Lumbar Radicular Pain.
The mechanism of pain control with pulsed radiofrequency (PRF) is unclear. ⋯ Combined PRF on DRG with TFESI showed similar outcomes to TFESI-alone in relieving pain in patients with lumbar disc prolapse. However, PRF on DRG caused a significant decrease in TNF-a serum levels at 3 months.
