Randomized Controlled Trial
Comparison of ultrasound-guided quadratus lumborum block-2 and quadratus lumborum block-3 for postoperative pain in cesarean section: A randomized clinical trial.
The aim of this study was to compare the postoperative analgesic effects of ultrasound-guided quadratus lumborum block-2 (QLB-2) and quadratus lumborum block-3 (QLB-3) after cesarean section (C/S) under general anesthesia. ⋯ This study demonstrated that, although both QLBs were safe and reliable, QLB-3 provides more effective analgesia and patient satisfaction than QLB-2 in C/S.

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 TrialComparison Among Ultrasound-Guided Thoracic Paravertebral Block, Erector Spinae Plane Block and Serratus Anterior Plane Block for Analgesia in Thoracotomy for Lung Surgery.
To compare the analgesic efficacy and safety of preoperative, single-shot ultrasound-guided thoracic paravertebral block (TPVB), erector spinae plane block (ESB), and serratus anterior plane block (SAPB) in thoracotomy pain. ⋯ The nerve blocks in decreasing order of analgesic efficacy in relieving post-thoracotomy pain would be ESB, TPVB, and SAPB.

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.
