Optimal techniques of ultrasound-guided superficial and deep parasternal intercostal plane blocks: a cadaveric study.
The optimal techniques of a parasternal intercostal plane (PIP) block to cover the T2-T6 intercostal nerves have not been elucidated. This pilot cadaveric study aims to determine the optimal injection techniques that achieve a consistent dye spread over the second to sixth intercostal spaces after both ultrasound-guided superficial and deep PIP blocks. We also investigated the presence of the transversus thoracis muscle at the first to sixth intercostal spaces and its sonographic identification agreement, as well as the location of the internal thoracic artery in relation to the lateral border of the sternum. ⋯ Triple injections at the second, fourth, and fifth intercostal spaces for the superficial approach and double injections at the third and fifth intercostal spaces for the deep approach were optimal techniques of the PIP blocks.

The clavipectoral fascia plane block (CPB) is a novel anesthetic management strategy proposed by Valdes-Vilches for clavicle fractures. This study aimed to investigate the distribution of the injected solution around the clavicle and the surrounding tissues. ⋯ The CPB effectively distributes the administered solution in the anterosuperior region of the clavicular periosteum, superficial muscular plane, and supraclavicular nerves. However, it does not affect the posteroinferior region of the clavicular periosteum or the deep muscular plane, including the CPF.

ReviewAnalgesic benefits of regional anesthesia in the perioperative management of transition-related surgery: a systematic review.
Transition-related surgery is an effective treatment for gender dysphoria, but the perioperative analgesic management of transgender patients is nuanced and potentially complicated by higher rates of mood and substance use disorders. Regional anesthetic techniques are known to reduce pain severity and opioid requirements; however, little is known regarding the relative analgesic effectiveness of regional anesthesia for transgender patients undergoing transition-related surgery. ⋯ Despite the ever-growing demand for transition-related surgery, the relative analgesic effectiveness of regional anesthesia for transgender patients undergoing transition-related surgery is very understudied and insufficient to guide clinical practice. Our systematic review of the literature serves to underscore regional anesthesia for transition-related surgery as a priority area for future research.

Meta Analysis Comparative Study
Ultrasound-guided subcostal approach of transversus abdominis plane block compared with wound infiltration for postoperative analgesia following laparoscopic cholecystectomy: A systematic review and meta-analysis.
Despite laparoscopic cholecystectomy (LC) is a commonly performed operation under ambulatory setting, significant postoperative pain is still a major concern. The ultrasound-guided subcostal approach of transversus abdominis plane (sTAP) blocks and wound infiltration (WI) are both widely practiced techniques to reduce postoperative pain in patients undergoing LC. Although these methods have been shown to relieve postoperative pain effectively, the relative analgesic efficacy between ultrasound-guided sTAP blocks and WI is not well known. ⋯ We conclude that there is low to moderate evidence to advocate that ultrasound-guided sTAP block has better analgesic effects than WI in patients undergoing LC. Further trials are needed with robust methodology and clearly defined outcomes.
