Intervention model description: There are two models for this study. The first group is erector spinae plane block group. The second one is sham block group
Primary purpose: TREATMENT

Brief summary: Postoperative pain is important following upper extremity surgery. Postoperative effective pain treatment provides early mobilization and shorter hospital stay.Ultrasound (US)-guided brachial plexus blocks such as interscalen, axillary, infraclavicular and supraclavicular block are usually performed.

The US-guided erector spina plane block (ESPB) is a novel interfacial plan block defined by Forero et al. Local anesthetic injection is administrated into the deep fascia of erector spinae. ESPB provides thoracic analgesia at T5 level, abdominal analgesia at T7-9 level, and lumbar analgesia at T10-12, L3 levels. There are a few case reports about the efficacy of ESPB for acute and chronic shoulder pain. However, there are no randomized clinical studies. The aim of this study is to evaluate the efficacy of the US-guided ESPB for postoperative analgesia management after upper extremity surgery.

Detailed description: Postoperative pain is an important issue in patients underwent upper extremity surgery. Pain causes a few problems; discomfortable patients, negative outcomes and longer rehabilitation. Postoperative effective pain treatment provides early mobilization and shorter hospital stay, thus complications due to hospitalization such as infection and thromboembolism may be reduced. Various techniques may be used for postoperative pain treatment. Opioids are one of the most preferred drugs among the analgesic agents. Parenteral opioids are generally performed for patients after surgery. However opioids have undesirable adverse events such as nausea, vomiting, itching, sedation and respiratory depression (opioid-related adverse events).

Various methods may be performed to reduce the use of systemic opioids and for effective pain treatment following arthroscopic shoulder surgery. Ultrasound (US)-guided brachial plexus blocks such as interscalen, axillary, infraclavicular and supraclavicular block are commonly used.

US-guided interfascial plane blocks have been used increasily due to the advantages of ultrasound in anesthesia practice. The US-guided erector spina plane block (ESPB) is a novel interfacial plan block defined by Forero et al. at 2016. The ESPB contains a local anesthetic injection into the deep fascia of erector spinae. This area is away from the pleural and neurological structures and thus minimizes the risk of complications due to injury. Visualization of sonoanatomy with US is easy, and the spread of local anesthesic agents can be easily seen under the erector spinae muscle. Thus, analgesia occurs in several dermatomes with cephalad-caudad way. Cadaveric studies have shown that the injection spreads to the ventral and dorsal roots of the spinal nerves. ESPB provides thoracic analgesia at T5 level, abdominal analgesia at T7-9 level, and lumbar analgesia at T10-12, L3 levels. To the best of our knowledge, there have been a few case reports about the efficacy of ESPB for acute and chronic shoulder pain. There are no randomized clinical studies, yet.

The aim of this study is to evaluate the efficacy of the US-guided ESPB for postoperative analgesia management after underwent upper extremity surgery. The primary aim is to compare perioperative and postoperative opioid consumption and the secondary aim is to evaluate postoperative pain scores (VAS), adverse effects related with opioids (allergic reaction, nausea, vomiting).
