Review Meta AnalysisEffects of Ultrasound-Guided Transversus Thoracic Muscle Plane Block on Postoperative Pain and Side Effects: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
The effects of the transversus thoracic muscle plane (TTP) block on postoperative pain have become increasingly controversial. This meta-analysis compared the effects of the TTP block versus no block on postoperative analgesia and side effects to determine whether this new technique is a reliable alternative for pain management. PubMed, Cochrane Library, Embase, Web of Science, ClinicalTrials.gov, China National Knowledge Infrastructure, Chongqing VIP information, and Wanfang Data were searched for clinical studies investigating the analgesic effect of the TTP block compared to controls. ⋯ Furthermore, the trial sequence analysis confirmed the result of less 24-hour postoperative analgesic consumption in the TTP block group. As a novel technique, the TTP block exhibited a superior postoperative analgesic effect during the early postoperative period. Nevertheless, additional well-designed RCTs are needed.

The role of neuromodulation in fascial plane blocks is unknown. This case report presents a complex patient who underwent shoulder arthroplasty with a high thoracic-erector spinae plane (HT-ESP) catheter that provided electrical and chemical neuromodulation, highlighting the potential of electrical stimulation in the identification of and therapy at the fascial plane level.

The bladder wall is innervated by a complex network of afferent nerves that detect bladder stretch during filling. Sensory signals, generated in response to distension, are relayed to the spinal cord and brain to evoke physiological and painful sensations and regulate urine storage and voiding. Hyperexcitability of these sensory pathways is a key component in the development of chronic bladder hypersensitivity disorders including interstitial cystitis/bladder pain syndrome and overactive bladder syndrome. ⋯ Further evaluation revealed that Ca V 3.2 blockers significantly inhibited both low- and high-threshold afferents, decreasing peak responses to distension, and delayed activation thresholds, thereby attenuating bladder afferent responses to both physiological and noxious distension. Nocifensive visceromotor responses to noxious bladder distension in vivo were also significantly reduced by inhibition of Ca V 3 with TTA-A2. Together, these data provide evidence of a major role for Ca V 3.2 in regulating bladder afferent responses to bladder distension and nociceptive signalling to the spinal cord.

Case ReportsNovel use of continuous pericapsular nerve group (PENG) block technique for traumatic superior and inferior pubic rami fractures: a case report.
Pubic rami fractures are painful injuries more commonly seen in the elderly with osteoporosis after high velocity trauma. In the most cases, management is conservative and non-operative with the goal to provide optimal pain relief to facilitate early mobilization and hospital discharge. Unfortunately, opioids remain the mainstay analgesic option and regional anesthesia techniques are limited but may include lumbar epidural anesthesia. ⋯ Analgesia options are limited in pubic rami fractures. We present the first published case of a novel use of the PENG block with a continuous catheter technique for the analgesic management of a traumatic superior and inferior pubic rami fracture. The clinical utility of this technique in pubic ramus fractures warrants further clinical investigation.
