Summary

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.

Conditions

• Regional Anesthesia

Interventions

Type	Name	Description
PROCEDURE	Patients receiving landmark-based brachial plexus blocks	The operator will visualize anatomical structures in real time, identify the brachial plexus (supraclavicular approach), and guide the needle to the injection site under direct ultrasound visualization
PROCEDURE	Landmark-Based Brachial Plexus Block	The operator will identify anatomical landmarks (e.g., interscalene groove, supraclavicular fossa) using palpation and surface anatomy. The needle will be inserted based on these landmarks, with no direct visualization of internal structures.
DRUG	Bupivacaine	injected in both group as local anesthetic agent ( at a standardized concentration and volume) to ensure comparability.
