Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to verify the effect of suprascapular nerve block and axillary nerve block in relieving postoperative pain after arthroscopic rotator cuff repair.

Are there differences in visual analog pain scale and patient's satisfaction? Are there differences in mean plasma pain related cytokines? The participants will undergo preemptive ultrasound guided suprascapular nerve block and axillary nerve block using each 0.75% ropivacaine 10mL or each 0.9% saline 10mL.

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors

An independent nurse uses a random number generator and allocates paticipants into the two group. Participant, investigator, and outcome assessor are blinded of the allocation information.
