Comparison of Interscalene Block and Suprascapular With Axillary Block

Study Overview
=================
Brief Summary
-----------------
In this study, the investigators are going to compare the analgesia effectiveness of interscalane block and suprascapular with axillary block in shoulder arthroplasties

Detailed Description
-----------------
In the preoperative period, the participants will be taken to the block room. The participants will be monitored, standard sedation will be applied. The first group will be get interscalene block. The second group will be get suprascapular and axillary block. The third group patient will be get no block. Afterwards, the participants will be operated under general anesthesia. A patient-controlled analgesia device will be attached to each group of participants and their postoperative follow-up will be made.
