Peng Block or Suprascapular Nerve Block for Postoperative Analgesia in Shoulder Artroscopy ?

Study Overview
=================
Brief Summary
-----------------
Arthroscopic shoulder surgery, which has been frequently applied in recent years, provides long-term positive clinical results and increases the quality of life after surgery, while it can cause severe pain in the early postoperative period. Postoperative pain management is very important in shoulder arthroplasty. Adequate pain control; mental state, nutrition, cost of care, rehabilitation, and patient satisfaction, are of great importance for the patients' recovery and contribute to a successful surgical outcome. In this study, the investigators aimed to compare the effects of suprascapular nerve block and shoulder pericapsular nerve block, which will be performed preoperatively with ultrasound, on the level of postoperative pain in patients who will undergo shoulder arthroscopy surgery under general anesthesia.

Detailed Description
-----------------
As a result of the power analysis the investigators conducted for this study, the minimum sample size was calculated as 32 people for each group, 64 people in total, at the 90% confidence interval. 64 patients who meet the inclusion criteria will be included in our study. The participants will be randomized and divided into 2 groups. Accordingly, the PENG block will be applied to 32 patients, and the suprascapular block will be applied to 32 patients.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The primary outcome measure of the study is the patients' postoperative pain scores (NRS) | Numerical rating scale (NRS) at 1, 6, 12, 18, 24, 30, and 36th hours. A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. For example, 0-10 where 0 is no pain and 10 is the worst pain imaginable. | 36 hours postoperatively | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Postoperative 36-hour total tramadol hydrochloride consumption | This will be measured by the PCA device in the 36 hours after | 36 hours postoperatively |
