Comparison of ultrasound-guided versus landmark-based techniques for peripheral nerve blocks in upper limb surgeries

The optimal technique for performing peripheral nerve blocks in upper-limb surgeries remains debated, particularly between ultrasound- guided and landmark-based approaches. Therefore, it is of interest to compare nerve blocks guided by ultrasound or landmarks in surgeries of the upper limb. Hence, 72 patients were randomly allocated into the US-guided group and landmark-based group. The ultrasound guided group had better success rate, a more rapid onset of block and fewer number of needle redirections as compared to the landmark based group. Both methods demonstrated comparable rates of complications and amount of operation time. The use of ultrasound guidance in the performance of peripheral nerve blocks in upper limb surgeries was found to be faster and more effective. This study advances knowledge by demonstrating that ultrasound-guided peripheral nerve blocks are more effective and efficient than landmark-based techniques in upper-limb surgeries, offering faster, more precise and safer outcomes.
