Summary
The research is designed as a single-center, prospective, randomized double-blind study. The
patients undergoing shoulder arthroscopy surgery in Istanbul University, Istanbul Faculty of
Medicine, Department of Orthopedics and Traumatology will be included. Patients who are
legally authorized to make decisions on their behalf will be informed about the research and
their written consent will be obtained. Patients who do not give consent will be excluded.
Ultrasonography (USG) guided combined suprascapular and axillary block will be performed
routinely for postoperative analgesia. After the block is performed, general anesthesia will
be applied. The patients will be divided into 4 groups. Three different doses of local
anesthetic will be given to patients (30 cc vs 20 cc vs 10 cc). Local anesthetic dose will be
the same for suprascapular and axillary blocks. The fourth group will be sham control. Pain
score will be determined by visual pain scoring (VAS) and analgesic consumption will be
provided by the use of a patient controlled analgesia (PCA) device with intravenous morphine
applied in routine practice to all four groups at the postoperative 1, 4, 8,12 and 24 hours.
Patient will be observed for postoperative nausea and vomiting, first time to mobilization,
length of hospital stay, analgesic consumption and satisfaction of surgeon and patient.
