A comparison of ultrasound‐guided interscalene and supraclavicular blocks for post‐operative analgesia after shoulder surgery

Abstract

This study showed no statistically significant difference in the duration of post-operative analgesia between the supraclavicular and interscalene blocks. However, the supraclavicular block was associated with a lower incidence of diaphragmatic paresis compared with that of the interscalene block after shoulder surgery.
