The suprascapular nerve, originating from the C5 trunk, provides innervation to the acromioclavicular and glenohumeral joints. The supraclavicular nerve, a branch of the cervical plexus, contributes to the sensory innervation of the upper deltoid region. Cervical and brachial plexus blocks can cause diaphragm paralysis. This study examined the effects of low-volume combined anterior suprascapular nerve block and superficial cervical plexus block on pain and phrenic nerve in participants underwent reverse shoulder arthroplasty surgery.
A retrospective analysis was performed on data obtained from eight participants who underwent reverse shoulder arthroplasty surgery. Anterior suprascapular nerve block and superficial cervical plexus block were applied to these participants. Anterior suprascapular nerve block was performed using 5 ml and superficial cervical plexus block was performed using 3 ml of %0,5 bupivacaine. Ultrasound was used to measure the diaphragm thickness at the end of inspiration and expiration, and to calculate the diaphragm thickness fraction. Postoperative pain management included patient-controlled analgesia with morphine, opioid consumption and VAS score recorded by pain observation forms.
Data will be collected by examining these pain observation forms and diaphragm thickness measurements.
