CommentCurrent versus revised anatomical targets for genicular nerve blockade and radiofrequency ablation: evidence from a cadaveric model.
Recent studies have proposed revised anatomical targets to improve accuracy of genicular nerve (GN) radiofrequency ablation (RFA). This study aims to compare the accuracy of classical and revised techniques for fluoroscopic-guided GN-RFA in cadaveric models. ⋯ This study demonstrates that the revised targets are more accurate than the current targets for GN-RFA.

Liposomal bupivacaine (Exparel®) is a sustained-release formulation of bupivacaine for use in surgical infiltration anaesthesia. We analysed the histological nerve toxicity and clinical effectiveness of perineural Exparel® alone or with added dexamethasone in a mouse model. ⋯ Perineural or systemic dexamethasone had a protective effect against the neural inflammation induced by bupivacaine, and perineural dexamethasone attenuated delayed inflammation induced by perineural Exparel®.

Randomized Controlled TrialComparison between the ultrasound-guided erector spinae block and the subcostal approach to the transversus abdominis plane block in obese patients undergoing sleeve gastrectomy; a randomized controlled trial.
Pain control in the morbidly obese has presented as an anesthetic challenge. The aim of this study is to assess the analgesic efficacy of ultrasound guided bilateral erector spinae block compared to bilateral subcostal transversus abdominis plane block. ⋯ Ultrasound-guided single-shot T9 erector spinae plane block lowers postoperative pain scores, and reduces intraoperative and postoperative opioid consumption compared with both the subcostal approach transversus abdominis plane block and the control group in obese patients that had undergone sleeve gastrectomy.
