Dexamethasone as a perineural adjuvant to a ropivacaine popliteal sciatic nerve block for pediatric foot surgery: a randomized, double-blind, placebo-controlled trial.
This study assessed the effect of perineural dexamethasone on block duration, opioid requirement, blood glucose levels, and stress response to surgery as measured by the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), following pediatric foot and ankle surgery. ⋯ Perineural dexamethasone significantly prolonged postoperative motor block duration and did not influence blood glucose, NLR, or PLR levels.

Fascicular injury is rare following needle transfixion: a study on median and ulnar isolated human nerves.
Needle trauma has been associated with peripheral nerve injury and neurological dysfunction. However, inadvertent needle puncture is frequent while postblock dysfunction is rare. We conducted a cadaveric study to evaluate the association between needle puncture and fascicular injury. ⋯ Fascicular injury is rare following needle transfixion. Needle injury alone is unlikely to explain postblock neurological dysfunction.

Anatomical evaluation of the superficial parasternal intercostal plane block.
Few cadaveric studies have evaluated the dye spread with superficial parasternal intercostal plane (SPIP) blocks. In this study, we examined the dye spread of an ultrasound-guided SPIP block in a human cadaveric model with single and double injection techniques. ⋯ The SPIP block demonstrated limited spread in this cadaver study. A single injection of this block may be of limited value and multiple SPIP injections may be needed to have adequate spread for anterior thoracic procedures.

Analgesic effectiveness of methoxyflurane inhaler during genicular nerve block in knee osteoarthritis: a randomized controlled trial.
Up to 30% of patients with knee osteoarthritis (KOA) have evidence of sensitization, with a similar proportion experiencing severe pain during procedures. Most patients with KOA are elderly and often develop side effects from intravenous sedation. Our study investigated the effectiveness of a methoxyflurane inhaler combined with local anesthesia in reducing procedural pain from genicular nerve block compared with local anesthesia alone. ⋯ A methoxyflurane inhaler combined with local anesthesia provided better procedural pain control than local anesthesia alone with no observable differences in adverse effects. Future studies evaluating the impact of a methoxyflurane inhaler on different types of painful procedures are warranted.
