ReviewThe European Society of Regional Anaesthesia and Pain Therapy and the American Society of Regional Anesthesia and Pain Medicine Joint Committee Practice Advisory on Controversial Topics in Pediatric Regional Anesthesia.
Some topics in the clinical management of regional anesthesia in children remain controversial. To evaluate and come to a consensus regarding some of these topics, The European Society of Regional Anaesthesia and Pain Therapy (ESRA) and the American Society of Regional Anesthesia and Pain Medicine (ASRA) developed a joint committee practice advisory on pediatric regional anesthesia (PRA). ⋯ High-level evidence is not yet available for the topics evaluated, and most recommendations are based on Evidence B studies. The ESRA/ASRA recommendations intend to provide guidance for the safe practice of regional anesthesia in children.

ReviewPercutaneous Balloon Compression for Trigeminal Neuralgia: Imaging and Technical Aspects.
Trigeminal neuralgia attacks are among the most painful conditions known. Trigeminal neuralgias are hypothesized to be caused by neurovascular conflict at the trigeminal root entry zone in the prepontine cistern. A range of therapeutic options is available including open surgical microvascular decompression and several percutaneous ablative techniques (eg, radiofrequency rhizotomy and glycerol gangliolysis). ⋯ This operative approach has proven popular with neurosurgeons as it is considered to be technically easier to perform than other methods. Nevertheless, pain physicians might regard this technique as challenging, relatively risky, and requiring special expertise. Accordingly, in this imaging article, we describe our percutaneous balloon compression procedure, paying particular attention to the technical and radiological details.

Randomized Controlled TrialChronological Changes in Ropivacaine Concentration and Analgesic Effects Between Transversus Abdominis Plane Block and Rectus Sheath Block.
Transversus abdominis plane block (TAPB) and rectus sheath block (RSB) are popular methods of controlling postoperative pain. Chronological changes in blood concentrations of local anesthetics have not been described, although a large amount of local anesthetic is required to block these compartments. We postulated that blood concentrations of anesthetics would peak earlier during TAPB than RSB (primary end point). Secondary end points were elapsed time from block until first postoperative rescue analgesia and affected dermatomes. ⋯ Peak ropivacaine concentrations were comparable during TAPB and RSB, but peaked earlier during TAPB. Although 150 mg of ropivacaine remained effective significantly longer during TAPB than RSB during laparoscopic surgery, this dose could cause local anesthetic systemic toxicity. The analgesic effects of blocks with less ropivacaine should be assessed.

Case ReportsWorsening of Neurologic Symptoms After Spinal Anesthesia in Two Patients With Spinal Stenosis.
Spinal stenosis has been proposed as a previously unrecognized risk factor for neurologic complications after neuraxial techniques. ⋯ We conclude that, until the relative contribution of patient and surgical (eg, positioning, retractors, hypotension) factors is known, the decision to perform neuraxial blockade in patients with severe symptoms of neuroclaudication or recently progressive symptomatic spinal stenosis should be made cautiously. Avoidance of spinal anesthesia is suggested for any procedure with prolonged lordotic positioning or any position that might cause a compromise of the spinal canal because subarachnoid block may contribute to any deterioration suffered by the patient.

Case ReportsA Novel Modified Retrocrural Approach for Celiac Plexus Block: The Single-Needle Retroaortic Technique.
For patients with pain from upper abdominal malignancies, celiac plexus neurolysis can provide an effective means of pain control. However, there are instances when traditionally described percutaneous approaches may not be technically feasible. ⋯ We present 4 cases of patients with pain from upper abdominal malignancies in whom we performed celiac plexus neurolysis using a novel single-needle retroaortic approach. All 4 patients had significant pain relief and no significant adverse effects from the retroaortic approach.
