Brief Summary
The shoulder, being an anatomical region innervated by different nerves, has a wide variety of analgesic approaches, which differ depending on the practitioner. New approaches are being developed based on the different innervation channels demonstrated in clinical and cadaver studies. Over time, the effectiveness of axillary block, suprascapular block, interscalene block, local infiltration, and various combinations, as well as non-regional methods, has been observed. The goal of these approaches is to achieve the highest possible level of patient comfort, high analgesic efficacy, and minimal complications. Studies have shown that the interscalene block has the highest analgesic efficacy and the most ideal postoperative results; therefore, it is frequently used as the gold standard in this field. Providing effective analgesia with a single intervention can also be cited as an aspect that increases patient comfort and simplifies the procedure. In interscalene block; unilateral transient diaphragmatic paralysis due to the spread of local anesthetics to the C7 nerve root, respiratory problems and potential spinal/epidural complications, new approaches are being followed and researched. Results from cervical/high thoracic erector spinae plane block (ESPB) and infraspinatus-teres minor interfascial plane block (ITMIPB) studies, which are the subject of new studies, strengthen the hypothesis that they provide effective analgesia. Neither of these blocks, performed with ultrasonography, carries the risks present in interscalene block. Although the usual risks of a peripheral nerve block are present for these procedures; the block sites are considered safer due to its distance from vascular structures and the reduced risk of additional complications. While small sample studies exist for each type of block, no studies comparing their effectiveness have been found. Besides reduced complications, another advantage of these two blocks is their ability to provide effective analgesia with a single-point injection. The aim of this study is to compare the analgesic efficacy of Cervical Erector Spine Plane Block (ESP) and Infraspinatus-Teres Minor Interfascial Plane Block (ITMIPB) applied for postoperative analgesia in ASA I-III patients undergoing shoulder surgery.

Study Arms (2)
Erector Spinae Plane Block Group
ACTIVE COMPARATORPatients receiving ultrasound-guided cervical erector spinae plane block for postoperative analgesia.
Infraspinatus Teres Minor Interfascial Plane Block Group
ACTIVE COMPARATORPatients receiving ultrasound-guided Infraspinatus Teres Minor Interfascial Plane Block for postoperative analgesia.
Interventions
Before shoulder surgery, Ultrasound-guided C8-T1 ESP block will be performed for postoperative analgesia
Before surgery, Ultrasound-guided Infraspinatus Teres Minor Interfascial Plane Block will be performed for postoperative analgesia
In the both groups, peripheral nerve blocks are performed by using Bupivacaine %0,25.
