简要总结
Regional anesthesia is a cornerstone in modern surgical practices due to its ability to provide effective pain management and reduce reliance on general anesthesia. Traditional landmark-based techniques, widely used due to their simplicity and cost-effectiveness, rely on surface anatomy and palpation to guide needle placement. However, these techniques are associated with a higher risk of complications, including failed blocks and nerve injuries.
Ultrasound-guided techniques have emerged as a safer, more precise alternative, offering real-time visualization of anatomical structures. Studies suggest that ultrasound guidance improves the success rate, reduces procedural time, and minimizes complications. Despite global advancements in ultrasound-guided regional anesthesia, limited research addresses its efficacy and safety specifically in Egyptian patients, whose unique anatomical and physiological characteristics may influence outcomes.
This study seeks to fill this knowledge gap and provide evidence-based guidance tailored to this population, focusing on brachial plexus blocks.
