Meta Analysis
Serratus anterior plane block for video-assisted thoracoscopic surgery: A meta-analysis of randomised controlled trials.
The serratus anterior plane block (SAPb) is a promising interfascial plane technique able to provide profound thoracic analgesia. As only a few studies with quite small patient samples are presently available, the analgesic efficacy of adding SAPb to general anaesthesia in video-assisted thoracoscopic surgery (VATS), compared with general anaesthesia only, remains unclear. ⋯ Compared with general anaesthesia only and if no other locoregional techniques are used, SAPb significantly reduces postoperative pain and nausea and vomiting in patients undergoing VATS. Grading of Recommendations Assessment, Development and Evaluation rating are, nonetheless, quite low, due to high heterogeneity. Well designed and properly powered RCTs are necessary to confirm these preliminary findings.

Suprazygomatic maxillary nerve block: an ultrasound and cadaveric study to identify correct sonoanatomical landmarks.
PURPOSE: Suprazygomatic maxillary nerve blocks (SMB) are used in adult and pediatric patients to provide analgesia for midface surgery and chronic maxillofacial pain syndromes. The ultrasound-guided SMB technique ensures visualisation of the needle tip, avoidance of the maxillary artery and confirmation of local anesthetic spread. The goal of this study was to correctly identify SMB sonoanatomical landmarks to ensure the nerve block is performed safely and effectively. ⋯ An improved understanding of the sonoanatomy will aid clinicians who are learning, performing and teaching the ultrasound-guided suprazygomatic approach to the maxillary nerve block.
