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.

scalene block using 5ml of ropivacaine
ISO block is a combined block of suprascapular nerve and brachial plexus cords using a single puncture
Healthpoint Hospital

RECRUITINGhemi-diaphragmatic pariesis
diaphragmatic caudal displacement will be measured (in cm) with real time ultrasound before the block performance and after the procedure
Time frame: 2-4 hours
analgesic efficacy (block success)
successful block = pain free (VAS 0) in recovery unit. VAS will be used to evaluate the pain (0 = pain free, 10= most sever pain)
Time frame: 2-4 hours
patient satisfaction
if the patient is satisfied with the analgesia technique or not
Time frame: 24 hours
duration of analgesia
duration between the block performance and the first requesting of pain killer (morphine)
Time frame: 24 hours
total morphine dose
the total morphine consumption within 24 hrs after the block performance
Time frame: 24 hours
