Primary purpose: TREATMENT

Brief summary: Suprascapular nerve is a mixed motor and sensory peripheral nerve arising from the superior trunk of brachial plexus.The suprascapular nerve runs through the posterior triangle of the neck, anterior of the trapezius muscle and dorsal of the omohyoid muscle, in direction of the scapula. Suprascapular nerve block is performed by anterior and posterior approach. Posterior approach of the suprascapular nerve block has been shown for many years to provide effective analgesia in the shoulder region for the chronic and acute pain. There are studies showing that suprascapular block with anterior approach provides effective analgesia in shoulder arthroscopy.

The aim of our study was to compare anterior and posterior approaches of suprascapular nerve block in terms of analgesic efficacy and patient safety.

Detailed description: This study is a prospective randomized clinical trial will be conducted between March 2022 and March 2023.Participant will divide into two groups as participant who underwent suprascapular nerve block with the anterior approach and participant who underwent suprascapular nerve block with the posterior approach. Bupivacaine 5 ml %0.5 will be injected both group. Diaphragmatic thickness fraction will be evaluated with ultrasound left and right 7.-8. subcostal anterior axillary border with the participant with the semi-sitting position. Diaphragmatic thickness fraction will measure before the block and after 30 minutes the surgery. Participants will administered intravenous morphine patient controlled analgesia for 24 hours stay. The amount of opioid analgesics given in both groups will be determined (in mg). Postoperative 4th, 6th, 12th, 24th hour Visual Analogue Scale scores of the participants and opioid consumptions until that hours will be evaluated. An addition participant will be determined according to the surgery.
