Review Meta AnalysisPeripheral nerve block anesthesia/analgesia for patients undergoing primary hip and knee arthroplasty: recommendations from the International Consensus on Anesthesia-Related Outcomes after Surgery (ICAROS) group based on a systematic review and meta-analysis of current literature.
Evidence-based international expert consensus regarding the impact of peripheral nerve block (PNB) use in total hip/knee arthroplasty surgery. ⋯ PNB use is recommended for patients undergoing THA and TKA except when contraindications preclude their use. Furthermore, the alignment of provider skills and practice location resources needs to be ensured. Evidence level: moderate; recommendation: strong.

Randomized Controlled TrialPerineural dexamethasone reduces rebound pain after ropivacaine single injection interscalene block for arthroscopic shoulder surgery: a randomized controlled trial.
A single injection interscalene block (ISB) is a common regional analgesic technique in patients undergoing arthroscopic shoulder surgery. However, rebound pain after ISB resolution may reduce its overall benefit. Our primary aim was to assess whether perineural dexamethasone reduces the intensity and incidence of rebound pain in patients undergoing arthroscopic shoulder surgery under general anesthesia combined with a preoperative single injection ISB. ⋯ Perineural dexamethasone added to ISB using ropivacaine led to a much smoother resolution of ISB, reflected in a significantly smaller increase in pain after block resolution, a lower incidence of rebound pain and a lower sleep disturbance during the first postoperative week.

Case ReportsPercutaneous radiofrequency treatment of the gasserian ganglion for trigeminal neuralgia complicated by trochlear nerve palsy: a case report.
Trigeminal neuralgia (TN) has the highest incidence of disorders causing facial pain. TN is provoked by benign stimuli, like shaving, leading to severe, short-lasting pain. Patients are initially treated using antiepileptic drugs; however, multiple invasive options are available when conservative treatment proves insufficient. Percutaneous radiofrequency treatment of the trigeminal, or gasserian, ganglion (RF-G) is a procedure regularly used in refractory patients with comorbidities. RF-G involves complex needle maneuvering to perform selective radiofrequency heat treatment of the affected divisions. We present a unique case of cranial nerve 4 (CN4) paralysis after RF-G. ⋯ Mention of postprocedural diplopia in guidelines is brief, and the exact incidence remains unknown. Different mechanisms for cranial nerve (CN) palsy have been postulated: incorrect technique, anatomical variations, and secondary heat injury. We observed postprocedural hemorrhage and hypothesized that bleeding might be a contributing factor in injury of CNs after RF-G.

Dural puncture during lumbar epidural access in the setting of degenerative spondylolisthesis: case series and risk mitigation strategies.
Degenerative spondylolisthesis is a common back pathology in the general adult population. Patients with this condition may present for epidural steroid injection, epidural blood patch, or epidural analgesia. ⋯ Patients with degenerative spondylolisthesis may be at higher risk for dural puncture due to stretching of the dura and contraction of the epidural space at the translated spinal level. In the following report, we summarize the cases and suggest risk mitigation strategies for both chronic and acute pain physicians.

Randomized Controlled TrialPostoperative pain reduction by pre-emptive N-acetylcysteine: an exploratory randomized controlled clinical trial.
A new potential target for multimodal pain management is the group-II metabotropic glutamate receptor subtypes, which can be activated by N-acetylcysteine. We investigated whether pre-emptive administration of N-acetylcysteine leads to a reduction in postoperative pain after laparoscopic inguinal hernia repair. ⋯ Without finding important differences between N-acetylcysteine and placebo group in pain scores postoperatively, but with a high percentage of bothersome side effects for the N-acetylcysteine group, we would not recommend the use of pre-emptive intravenous N-acetylcysteine to reduce postoperative pain in laparoscopic inguinal hernia repair patients based on this study.
