Sparing Diaphragm; ISO Block Versus Low Volume Scalene Block

Not Applicable
Conditions
Shoulder Arthropathy Associated With Other Conditions
Interventions
Procedure: ISO block
Procedure: scalene block
Registration Number
NCT03331237
Lead Sponsor
Healthpoint Hospital
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
hemi-diaphragmatic pariesis2-4 hours

diaphragmatic caudal displacement will be measured (in cm) with real time ultrasound before the block performance and after the procedure

Secondary Outcome Measures
NameTimeMethod
duration of analgesia24 hours

duration between the block performance and the first requesting of pain killer (morphine)

total morphine dose24 hours

the total morphine consumption within 24 hrs after the block performance

patient satisfaction24 hours

if the patient is satisfied with the analgesia technique or not

analgesic efficacy (block success)2-4 hours

successful block = pain free (VAS 0) in recovery unit. VAS will be used to evaluate the pain (0 = pain free, 10= most sever pain)
