Purpose: The purpose of this study is to compare the result of combined sono-guided suprascapular nerve block (SSNB) and axillary nerve block (ANB) with isolated SSNB in postoperative pain following arthroscopic rotator cuff repair. Our hypothesis was that SSNB combined ANB would show a more effective anesthesia for arthroscopic rotator cuff repair as compared with SSNB only.
Methods: Forty-two patients with rotator cuff tear who had undergone arthroscopic rotator cuff repair were enrolled in this study. Among them, 21 patients were randomly allocated into group I, and received SSNB and ANB with each 10mL ropivacaine. The other 21 patients were allocated into group II, and received SSNB with 10mL ropivacaine and ANB with 10mL normal saline. Visual Analogue Scale (VAS) pain score, patient's satisfaction (SAT), and Lateral Pain Index (LPI), etc was checked at postoperative 1, 3, 6, 12, 18, 24, 36, and 48 hours.

Experimental: Group I, SSNB & ANB
21 patients were randomly allocated into group I, and received suprascapular nerve block (SSNB) and axillary nerve block (ANB) both with 10mL ropivacaine.
Procedure: Group I, SSNB & ANB
Suprascapular nerve block (SSNB) and axillary nerve block(ANB) were performed by one anesthesiologist under sono-guidance. 23 gauge spinal needle was used. SSNB was done at first and the entry site was the mid point between an anterolateral angle of acromion and medial end of scapular spine. With the linear probe, the suprascapular notch was identified and the block was performed penetrating the transverse scapular ligament because the scapular nerve and artery were located at the suprascapular notch. Just after the SSNB, ANB was performed and the entry site was the point 1.5 cm medial and 2cm inferior to posterolateral angle of acromion. With the linear probe, posterior circumflex artery was identified and the block was done at just above the artery.
Placebo Comparator: Group II, SSNB alone
The other 21 patients were allocated into group II, and received suprascapular nerve block (SSNB) with 10mL ropivacaine and axillary nerve block (ANB) with placebo (10mL normal saline).
Procedure: Group II, SSNB alone
This is same as the Group I, SSNB & ANB, but ANB was performed with placebo(10mL normal saline).
- Visual analogue pain scale [ Time Frame: postoperative 48 hours ]VAS pain score was selected from 0 to 10. 0 was no pain and 10 was severe pain that the patient had ever experienced.
- Patient satisfaction (SAT) [ Time Frame: postoperative 48 hours ]SAT was also selected from 0 to 10. 0 was unsatisfactory and 10 was very satisfactory.
- lateral pain index (LPI) [ Time Frame: postoperative 48 hours ]The percentage of lateral pain was determined as a value between 0 and 100. LPI was determined as VAS pain score × the percentage of lateral pain of shoulder ÷ 100.
