Randomized Controlled Trial
Effect of Adding Perineural Methylprednisolone to Peripheral Nerve Blocks Combined With Intravenous Dexamethasone for Prolonged Postdischarge Analgesia After Fast-track Total Knee Arthroplasty: A Randomized Controlled Trial.
Patients undergoing total knee arthroplasty (TKA) may experience moderate-to-severe subacute pain after hospital discharge that may be undermanaged. We aimed to evaluate the effect of methylprednisolone added to ultrasound-guided peripheral nerve blocks (PNBs) combined with multimodal analgesia including intravenous dexamethasone for prolonged analgesia after early discharge. ⋯ Adding perineural methylprednisolone to ultrasound-guided PNBs for multimodal analgesia with intravenous dexamethasone did not prolong analgesia and improved the functional ability after fast-track TKA within 12 postdischarge days. However, the incidence moderate-to-severe pain may increase between the 2-week and 3-month follow-up.

Randomized Controlled TrialComparison between ultrasound-guided multi-injection intertransverse process and thoracic paravertebral blocks for major breast cancer surgery: a randomized non-inferiority trial.
This study investigated whether a novel multi-injection intertransverse process block could provide non-inferior analgesia and recovery quality following major breast cancer surgery compared with the multi-injection thoracic paravertebral block. ⋯ Compared with a multi-injection thoracic paravertebral block, the multi-injection intertransverse process block provided non-inferior analgesia within 30 min in the recovery room and recovery quality at 24 hours following major breast cancer surgery in females.

Randomized Controlled Trial
A randomised controlled trial of the non-inferiority of erector spinae plane block vs. thoracic paravertebral block for laparoscopic nephro-ureterectomy.
Erector spinae plane block and paravertebral block can provide analgesia for abdominal surgery. It is unclear whether erector spinae block is inferior to paravertebral block. We aimed to determine whether sufentanil dose and pain intensity (11-point scale) to 24 h after erector spinae block exceeded those after paravertebral block by no more than 5 μg and 1 point, respectively. ⋯ Median (IQR [range]) pain were 1.5 (1.0-2.0 [0.0-5.3]) after erector spinae block vs. 2.0 (1.0-2.5 [0.0-6.0]) after paravertebral block, median (95% CI) difference 0.3 (0.0-0.5), erector spinae non-inferiority p < 0.001. Adverse events did not differ between groups. Erector spinae block analgesia was not inferior to paravertebral block analgesia after laparoscopic nephroureterectomy.

Randomized Controlled TrialModified thoracoabdominal nerve block through perichondrial approach (M-TAPA) vs local infiltration for pain management after laparoscopic cholecystectomy surgery: a randomized study.
Modified thoracoabdominal nerves block through perichondrial approach (M-TAPA) targets thoracoabdominal nerves. Our primary aim was to compare M-TAPA vs local infiltration on pain management in patients underwent laparoscopic cholecystectomy (LC) surgery. ⋯ M-TAPA provides superior analgesia compared to LI in patients undergoing LC.

This study aims to determine temperature effect on nerve conduction block induced by high-frequency (kHz) biphasic stimulation (HFBS). ⋯ Temperature has an important influence on HFBS-induced nerve block. The blocking mechanisms underlying acute and poststimulation nerve blocks are likely to be very different.
