Efficacy of Nalbuphine as a Local Anesthetic Adjuvant for Brachial Plexus Block: A Systematic Review and Meta-analysis.
Nalbuphine has been increasingly used as a local anesthetic adjuvant to extend the duration of analgesia in brachial plexus block (BPB). ⋯ Perineural use of nalbuphine in BPB is an effective strategy for analgesia in adult patients undergoing upper extremity surgery.

Also in ambulatory surgery, there will usually be a need for analgesic medication to deal with postoperative pain. Even so, a significant proportion of ambulatory surgery patients have unacceptable postoperative pain, and there is a need for better education in how to provide proper prophylaxis and treatment. ⋯ Multimodal analgesia should start pre or per-operatively and include paracetamol, nonsteroidal anti-inflammatory drug (NSAID), dexamethasone (or alternative glucocorticoid) and local anaesthetic wound infiltration, unless contraindicated in the individual case. Paracetamol and NSAID should be continued postoperatively, supplemented with opioid on top as needed. Extra analgesia may be considered when appropriate and needed. First-line options include nerve blocks or interfascial plane blocks and i.v. lidocaine infusion. In addition, gabapentinnoids, dexmedetomidine, ketamine infusion and clonidine may be used, but adverse effects of sedation, dizziness and hypotension must be carefully considered in the ambulatory setting.

A magnetic resonance imaging study of the sciatic nerve variation in the pediatric gluteal region: implications for the posterior approach of the sciatic nerve blockade.
In pediatric patients, the sciatic nerve is one of the most commonly blocked peripheral nerves during orthopedic procedures of the lower limb. Ultrasound guidance is the current standard for a successful localization of the sciatic nerve in the gluteal region. Relevant anatomical landmarks are also used to determine the nerve location when ultrasound is not available or inadequate. However, reports have demonstrated paucity of information regarding the sciatic nerve location and variation in the hip throughout pediatric development. This imaging study aimed to document and analyze the relative morphometric relationship of the sciatic nerve in the pediatric gluteal region throughout development. ⋯ Despite the small sample size of younger age group, this study is the first to document the morphometric changes of the sciatic nerve in the gluteal region across pediatric development and may be useful for providing confirmatory guidelines for nerve location when ultrasound is not accessible or cannot be utilized for practice.
