Randomized Controlled Trial
Efficacy and safety of remimazolam for procedural sedation during ultrasound-guided transversus abdominis plane block and rectus sheath block in patients undergoing abdominal tumor surgery: a single-center randomized controlled trial.
To explore the efficacy and safety of remimazolam for procedural sedation during ultrasound-guided nerve block administration in patients undergoing abdominal tumor surgery, in order to improve and optimize remimazolam use in procedural sedation and clinical anesthesia. ⋯ Remimazolam can be used safely for procedural sedation during ultrasound-guided nerve block administration in patients undergoing abdominal tumor surgery. The sedation effect is better than that with either midazolam or dexmedetomidine, and sedation can be achieved quickly without obvious hemodynamic fluctuations. Remimazolam is associated with better heart rate stability, and slightly higher incidences of hypoxemia and injection pain than are midazolam and dexmedetomidine (no statistically significant difference). The higher incidence of hypoxemia with remimazolam may be related to enhanced sufentanil opioid analgesia, and the mechanism of injection pain with remimazolam must be studied further and clarified.

Randomized Controlled TrialParavertebral block versus erector spinae plane block for analgesia in modified radical mastectomy: a randomized, prospective, double-blind study.
Pain control after breast surgery is crucial and supported with regional techniques. Paravertebral block (TPVB) is shown to be effective in postoperative pain management. Erector spinae plane block (ESPB) is assumed to have a similar analgesic effect as an easier and safer block. Our aim was to compare TPVB and ESPB for modified radical mastectomy (MRM) in terms of analgesic efficiency and dermatomal spread. ⋯ Thoracal paravertebral block reduced morphine consumption compared to ESPB after MRM, albeit a small difference. A through coverage of TPVB may be preferred with experienced operators in MRM due to lower pain scores.

Bilateral Ultrasound-Guided Erector Spinae Plane Block for Pectus Excavatum Surgery: A Retrospective Propensity-Score Study.
Pectus excavatum (PE) repair is burdened by severe postoperative pain. This retrospective study aimed to determine whether the analgesic effect of ultrasound-guided erector spinae plane block (ESPB) plus standard intravenous analgesia (SIVA) might be superior to SIVA alone in pain control after PE surgical repair via Ravitch or Nuss technique. ⋯ Erector spinae plane block may be an effective option for pain management after surgical repair of PE as part of a multimodal approach. This study showed good perioperative analgesia, opioid sparing, and reduced opioid-related adverse effects.

Forearm fractures in children often require closed reduction in the emergency setting. The choice of anaesthesia influences the degree of pain relief, which determines the success of reduction. Main methods of anaesthesia include procedural sedation and analgesia, haematoma block, intravenous regional anaesthesia (IVRA) and regional nerve blocks. However, their comparative effectiveness is unclear. This study aims to synthesise peer-reviewed evidence and identify the most effective, in terms of pain reduction, and safest anaesthetic method. ⋯ Few randomised controlled trials compared anaesthetic methods in the closed reduction of paediatric forearm fractures. High heterogeneity precluded meta-analysis. Overall, current data are insufficient to guide the choice of anaesthetic method in emergency settings. More adequately powered trials, conducted using standardised methods, are required.
