Abstract

Background: The use of ultrasound for supported brachial plexus block reduces the required volume of local anesthetic, minimizing undesirable complications while maintaining effective anesthesia. Objectives:1. To evaluate the anesthetic effectiveness during and after surgery from the distal third of the arm to the hand using 0.375% levobupivacaine versus 1.5% lidocaine under ultrasound guidance for supraclavicular brachial plexus block. 2. To assess the adverse effects encountered in both groups. Materials and methods: In a comparative prospective descriptive study, 100 patients at Hue University of Medicine and Pharmacy Hospital indicated for surgery from the distal third of the arm to the hand were randomly divided into two groups from May 2021 to May 2023. Results: The success rate of anesthesia was 96% in the levobupivacaine group and 98% in the lidocaine group. The total sensory and motor block durations in the levobupivacaine group were 7.53 ± 1.66 and 6.45 ± 1.34 hours, respectively, significantly longer than those in the lidocaine group, which were 3.57 ± 1.20 and 3.03 ± 1.26 hours (p < 0.05). The duration of analgesia in the levobupivacaine group (9.36 ± 1.90 hours) was significantly longer than in the lidocaine group (4.62 ± 1.77 hours) (p < 0.05). No complications occurred in either group. Conclusion: With the use of ultrasound, both groups achieved effective analgesia during and after surgery, reducing complication rates with low volumes and doses of local anesthetics. However, the levobupivacaine group had a superior advantage over the lidocaine group.
