Case Reports
Cauda Equina Syndrome after Unilateral Medial Branch Block of the Lower Right Lumbar Zygapophyseal Joints.
Medial branch blockade of the lumbar facet joints is widely performed and generally accepted as a safe intervention. We present a case of neurological damage following a medial branch blockade with local anesthetic and steroid. A patient suffering from chronic low back pain radiating to the buttocks and thighs underwent nine medial branch blockades over a few years. ⋯ Although the patient received nine sets of injections uneventfully during the previous 36 months, this procedure took place 3 months following spinal surgery. This rare, but catastrophic case of cauda equina syndrome occurred following L3-4 , L4-5 , and L5 -S1 medial branch blockades 3 months after spinal surgery, which is believed to be caused by accidental intra-arterial injection of particulate methylprednisolone, with consequent aggregates causing blockage and ensuing ischemia. Therefore we suggest particulate steroid preparations should not be used in axial spinal injection.

Randomized Controlled Trial
Bilateral ultrasound-guided erector spinae plane block for postoperative persistent low back pain in lumbar disc surgery.
Persistent low back pain is an important disability after lumbar disc surgery. Erector spinae plane block (ESPB) is highly effective in providing post-surgical pain control, but its effectiveness in long-term persistent low back pain has not been investigated. The aim of this randomized controlled trial was to investigate the effect of ESPB on the reduction of persistent low back pain after surgery. ⋯ ESPB, which has a low risk of complications and is simple to perform, has been found useful in the treatment of persistent low back pain after disc surgery.

Randomized Controlled Trial
Ultrasound-guided Erector Spinae Muscle Block Versus Ultrasound-guided Caudal Block in Pediatric Patients Undergoing Lower Abdominal Surgeries.
The erector spinae plane block is a new regional anesthetic technique that is gaining popularity in pediatric medicine. ⋯ Ultrasound-guided erector spinae block was safe and effective in pediatric patients undergoing unilateral lower abdominal surgery as it provided a longer duration of analgesia and less analgesic requirement than caudal block and fewer side effects.
