For shoulder analgesia, both ISO block and low volume scalene (LVS) block (using 5 ml of local anesthetics) are suggested to have a low incidence of hemi-diaphragmatic pariesis (HDP).
The aim of this study was to compare the incidence of HDP and the analgesic efficacy of the LVS block versus ISO block.

| ISO block |
| Procedure |
ISO block is a combined block of suprascapular nerve and brachial plexus cords using a single puncture |
