Review Meta Analysis
The serratus anterior plane block for analgesia after thoracic surgery: A meta-analysis of randomized controlled trails.
The serratus anterior plane (SAP) block is a newer method that can be used in patients undergoing thoracic surgeries. The postoperative analgesia efficacy of SAP blocks for thoracic surgery remains controversial. We conduct a meta-analysis to evaluate the analgesia of SAP blocks after thoracic surgery. ⋯ The SAP block can play an important role in the management of pain after thoracic surgery by reducing both pain scores and 24-h postoperative opioids consumption. In addition, there is fewer incidence of PONV in the SAP block group.

Meta Analysis Comparative StudyIs Supraclavicular Block as Good as Interscalene Block for Acute Pain Control Following Shoulder Surgery? A Systematic Review and Meta-analysis.
Interscalene block (ISB) is the acute pain management technique of choice for shoulder surgery, but its undesirable respiratory side effects have prompted seeking alternatives. Supraclavicular block (SCB) is proposed as an ISB alternative, but evidence of comparative analgesic and respiratory-sparing effects is inconsistent. We compared the analgesic and respiratory effects of SCB and ISB for shoulder surgery. ⋯ For acute pain control following shoulder surgery, high-quality evidence indicates that SCB can be used as an effective ISB alternative. SCB is noninferior for postoperative opioid consumption and acute pain, and it reduces the odds of postblock respiratory dysfunction.

For decades local anesthetics have proven to be safe and effective drugs in the clinical practice, crucially promoting the enormous achievements in regional anesthesia. Meanwhile, it is a well-known fact that local anesthetics are much more than just "simple" sodium channel blockers. They also interact with numerous other ion channels and subcellular structures, enhancing nerve blockade and resulting in systemic "alternative" effects, which can sometimes even be clinically used. ⋯ Local anesthetic-induced systemic toxicity is meanwhile rare but still a potentially life-threatening event, frequently resulting from accidental intravascular injection or extensive systemic resorption. Consequently, slow and fractional application of these agents with intermittent aspiration helps to prevent toxic sequelae. If toxic symptoms occur, however, the intravenous infusion of 20% lipid solutions in addition to basic treatment measures can enhance the success of treatment.
