Nociceptive afferent signaling evoked by inflammation and nerve injury is mediated by the opening of ligand-gated and voltage-gated receptors or channels localized to cholesterol-rich lipid raft membrane domains. Dorsal root ganglion (DRG) nociceptors express high levels of toll-like receptor 4 (TLR4), which also localize to lipid rafts. Genetic deletion or pharmacologic blocking of TLR4 diminishes pain associated with chemotherapy-induced peripheral neuropathy (CIPN). ⋯ Regulation of TRPV1-TLR4 interactions and their associated lipid rafts by AIBP covaried with the enduring reversal of mechanical allodynia otherwise observed in CIPN. In addition, AIBP reduced intracellular calcium in response to the TRPV1 agonist capsaicin, which was increased in DRG neurons from paclitaxel-treated mice and in the naïve mouse DRG neurons incubated in vitro with paclitaxel. Together, these results suggest that the assembly of nociceptive and inflammatory receptors in the environment of lipid rafts regulates nociceptive signaling in DRG neurons and that AIBP can control lipid raft-associated nociceptive processing.

ReviewRegional anesthesia as part of enhanced recovery strategies in pediatric cardiac surgery.
The purpose of this review article was to highlight the enhanced recovery protocols in pediatric cardiac surgery, including early extubation, rapid mobilization and recovery, reduction of opioid-related side effects, and length of pediatric ICU and hospital stay, resulting in decreased costs and perioperative morbidity, by introducing recent trends in perioperative anesthesia management combined with peripheral nerve blocks. ⋯ Recent remarkable advances in combined ultrasound techniques have made it possible to perform various peripheral nerve blocks. The major strategy underlying fast-track anesthesia management is to achieve good analgesia while reducing perioperative opioid use. Furthermore, it is important to consider early extubation not only as a competition for time to extubation but also as the culmination of a qualitative improvement in the outcome of treatment for each patient.

Randomized Controlled TrialComparison of ultrasound-guided erector spinae plane block and thoracic paravertebral block for postoperative analgesia after laparoscopic nephrectomy: a randomized controlled non-inferiority clinical trial.
Thoracic paravertebral block offers effective analgesia after laparoscopic nephrectomy but has potential severe complication risks. Erector spinae plane block has been described for analgesia after abdominal surgery. However, there are no prospective randomized trials determining if ultrasound-guided erector spinae plane block is non-inferior to thoracic paravertebral block in terms of analgesia after abdominal surgeries including laparoscopic nephrectomy. ⋯ This study demonstrates that erector spinae plane block provides non-inferior analgesia for pain at rest within 24 postoperative hours in comparison to thoracic paravertebral block for laparoscopic nephrectomy.

Our meta-analysis aimed to compare the analgesic effectiveness of ultrasound-guided preoperative erector spinae plane block (ESPB) versus paravertebral nerve block (PVB) in breast surgery. ⋯ Both ultrasound-guided preoperative ESPB and PVB showed comparable analgesic effects in patients undergoing breast surgery. However, with a significantly shorter procedure time and higher block success rate, our findings suggest that ESPB may be a simple alternative to PVB in breast surgery.
