Anatomical assessments of injectate spread stratified by the volume of the intertransverse process block at the T2 level.
This cadaveric study aimed to analyze injectate spread to target nerves during a single-injection, ultrasound-guided intertransverse process block. ⋯ An injectate volume of 20 mL was required for consistent staining of the dorsal rami, spinal nerve, and dorsal root ganglion in an intertransverse process block. Although an augmented injectate volume was associated with an increased likelihood of target nerve staining, consistent staining of the sympathetic ganglion, rami communicans, and ventral ramus was not observed, even at a volume of 20 mL. The current study presents initial findings suggesting that as opposed to a sympathetic ganglion block, a 20 mL intertransverse process block may act as a feasible substitute for dorsal root ganglion, spinal nerve, and medial branch blocks within a clinical context.

Randomized Controlled Trial Comparative Study
Postoperative analgesic effectiveness of ultrasound-guided bilateral erector spinae plane block vs. rectus sheath block for midline abdominal surgery in a low- and middle-income country: a randomised controlled trial.
The use of erector spinae plane block and rectus sheath block for postoperative analgesia in midline abdominal procedures is becoming more common. However, the most effective and appropriate method remains unclear. We aimed to compare the postoperative analgesic effecacy of ultrasound-guided bilateral erector spinae plane blocks with rectus sheath blocks for midline abdominal surgery in a low- and middle-income country. ⋯ Erector spinae plane blocks are more effective than rectus sheath blocks for the management of postoperative pain following midline abdominal surgery. Integration of erector spinae plane blocks into multimodal opioid-sparing analgesic strategies after midline abdominal surgeries may promote enhanced patient recovery in low-and middle-income countries.

Erector Spinae Blocks for opioid-sparing multimodal pain management after Pediatric Cardiac Surgery.
Peripheral regional anesthesia is proposed to enhance recovery. We sought to evaluate the efficacy of bilateral continuous erector spinae plane blocks (B-ESpB) for postoperative analgesia and the impact on recovery in children undergoing cardiac surgery. ⋯ B-ESpBs are safe in children undergoing cardiac surgery. When performed as part of a multimodal pain strategy in an enhanced recovery after cardiac surgery program, pediatric patients with B-ESpB experience good pain control and require fewer opioids in the first 48 hours.

To simulate bupivacaine pharmacokinetics in scenarios of labor epidural analgesia (LEA) extended for intrapartum cesarean delivery (CD) with epidural or intrathecal boluses, followed by transversus abdominis plane (TAP) block with liposomal bupivacaine (LB) for postcesarean analgesia. ⋯ Across 6 different simulations of TAP blocks for intrapartum CD analgesia, LEA with bupivacaine (with or without boluses for extension and including a conservative modeling of lidocaine without epinephrine), followed by TAP block with LB and/or bupivacaine hydrochloride 0, 1, or 2 h after CD, is unlikely to result in bupivacaine plasma concentrations reaching local anesthetic systemic toxicity thresholds in healthy patients.
