Abstract
Abstract
Introduction: Interscalene nerve blockade (ISB) main hindrance is the high risk of
ipsilateral phrenic nerve block with sequential hemi-diaphragmatic paralysis. The
employment of costoclavicular block as an alternative technique of infraclavicular block
in combination with suprascapular block (SSB) may provide comparable analgesic
potency to the sole use of standard ISB with negligible hemi-diaphragmatic affection
Aim of the study: This trial aims to compare the analgesic efficiency and hemi-
diaphragmatic paralysis of the standard ultrasound-guided interscalene brachial plexus
block with the combined use of costoclavicular approach of infraclavicular brachial
plexus block and suprascapular nerve block for patients undergoing arthroscopic rotator
cuff repair.
Method and Results: The study was a prospective, randomized, duble-blinded, and
controlled clinical trial.
The patients were allocated into two groups; each of 33 patients:
(ISB) group received ISB followed by general anesthesia
(CSB) group received ICB using costoclavicular approach and SSB followed by
general anesthesia.
The Primary outcome was the cumulative morphine consumption at the first 24 hours
postoperatively.
Conclusion: This prospective randomized study demonstrates that analgesia
provided by combination of costoclavicular & suprascapular blocks is non-inferior to an
interscalene nerve block and best preserves pulmonary function.
