Abstract

Objective: To evaluate the effectiveness of initial implementation of untrasound-guided brachial plexus blockage. Subjects and methods: In 30 patients undergoing upper limb surgery from arm to hand with ASA I, II, aged from 16 to 70 at Phu Tho Provincial General hospital from 2/2020 to 9/2020. The untrasound-guided interscalene brachial plexus was performed with 30 ml of 1% lidocaine mixed with adrenaline 150mcg. The sensory and motor evaluated by Hollmen score, including paresthesia, the onset and duration of sesorry, motor blockage, the success rate and and complications were noted. Result: The mean onset of sensory and motor blockage were  5.00±1,23mins, 16,55±2,58mins. Mean duration of sensory and motor blockage were 135.46±12.54mins, 146,33±14,41mins. The success rate was 90% good, 10% quite good, no failures and major complication occurred in the study group. One cas has broken nerve sheath because of too strong pump. Conclusion: The untrasound-guided interscalene brachial plexus blockage lead to a high success rate (90% good, 10 % qiute good), a short onset and a long duration of sensory and motor blockage with the use of low volume of local anesthetic.
