So sánh hiệu quả gây tê đám rối thần kinh cánh tay đường trên đòn dưới hướng dẫn siêu âm với máy kích thích thần kinh cơ cho phẫu thuật chi trên tại Bệnh viện Quân y 7A

Abstract

Objective: To compare the onset and duration of sensory and motor blocking effects, success and complications rates of two techniques. Subject and method: 60 patients indicated for upper limb surgeries at 7A Military Hospital from May 2020 to September 2020 were randomly divided into two groups. Group I underwent ultrasound-guided supraclavicular brachial plexus blocks, group I received 20ml levobupivacaine 0.5% combined lidocaine 2% and 1/200.000 adrenaline. Group II with nerve stimulator received 20ml levobupivacaine 0.5% combined lidocain 2% and adrenalin 1/200000. Result: The procedure time (5.5 ± 2.68 vs 4.6 ± 1.72 min), time of onset of sensory suppression (5.03 ± 1.09 vs 9.6 ± 1.58 min) and time of onset of motor block (8.0 ± 1.98 vs 12.26 ± 2.27 min) in group I were significant shorter those in Group II (p<0.05). The duration of sensory and motor block (335.15 ± 115.30 vs 312.30 ± 312.30 minutes and 285.13 ± 103.20 vs 225.40 ± 98.35 minutes, respectively) were significant longer in group I than in Group II (p<0.05). Good numbness rate (96.66% vs 90%) and complications (3.3% vs 9.9%) were comparable between two groups. Conclusion: Supraclavicular brachial plexus blocks under ultrasound guidance provided faster onset, longer duration of sensory and motor block, higher success rates with fewer complications in comparison with nerve stimulator technique.
