USG-Guided Supraclavicular Brachial Plexus Block: Single-Point vs. Multiple-Point Injection
Recently published research paper compares the success rates and differences in nerve sparing, procedure time, and onset of block between single-point injection and multiple-point injection techniques of the supraclavicular brachial plexus block. A total of 204 patients were given USG-guided supraclavicular brachial plexus block and were randomly divided into two groups. The study found that...
Recently published research paper compares the success rates and differences in nerve sparing, procedure time, and onset of block between single-point injection and multiple-point injection techniques of the supraclavicular brachial plexus block. A total of 204 patients were given USG-guided supraclavicular brachial plexus block and were randomly divided into two groups. The study found that the success rate for the multiple-point injection technique was 98%, compared to 60.8% for the single-point injection technique. The onset of sensory and motor block was similar in both groups, but the procedure time was longer in the multiple-point group. The study confirmed that nerve sparing is much lower in the multiple-point injection technique, with the intercostobrachial nerve being most commonly spared. The supraclavicular brachial plexus block was found to be a popular and effective regional anesthesia technique for upper limb surgeries. Ultrasonography (USG) guidance was highlighted as essential for reducing the incidence of phrenic nerve palsy. Overall, the paper concluded that the multiple-point injection technique of the supraclavicular block had a better success rate compared to the single-point injection technique. However, it noted that nerve sparing was more frequent in the single-point injection technique, but the onset of sensory and motor block was similar to the multiple-point injection group.
Conclusion
The study concluded that both techniques have their advantages and areas of improvement, emphasizing the importance of USG guidance for optimal outcomes in the supraclavicular brachial plexus block. The paper provides detailed insights into the differences between the two techniques and their respective impact on nerve sparing, procedure time, and onset of block. Additionally, the study sought to address a significant research gap in the comparison of these techniques, providing valuable evidence for anesthesiologists and researchers in the field.
