ABSTRACT
BACKGROUND:
With ultrasound guidance, the success rate of brachial plexus block (BPB) is 95-100% and the anesthetic time has become a more important factor than before. Many investigators have compared ultrasound guidance with the nerve stimulation technique, but there are few studies comparing different approaches via the same ultrasound guidance. We compared the axillary BPB with the infraclavicular BPB under ultrasound guidance.METHODS:
Twenty-two ASA physical status I-II patients presenting with elective forearm surgery were prospectively randomized to receive an axillary BPB (group AX) or an infraclavicular BPB (group IC) with ultrasound guidance. Both groups received a total of 20 ml of 1.5% lidocaine with 5 microg/ml epinephrine and 0.1 mEq/ml sodium bicarbonate. Patients were then evaluated for block onset and block performance time was also recorded.RESULTS:
Group IC demonstrated a reduction in performance time vs. group AX (622 +/- 139 sec vs. 789 +/- 131 sec, P < 0.05). But, the onset time was longer in group IC than in group AX (7.7 +/- 8.8 min vs. 1.4 +/- 2.3 min, P < 0.05). All blocks were successful in both groups.CONCLUSIONS:
Under ultrasound guidance, infraclavicular BPB was faster to perform than the axillary approach. But the block onset was slower with the infraclavicular approach.
