Analgesic Effect of Supraclavicular Block and Interscalene Analgesia Versus an Intercostobrachial Nerve Block Versus PCA in Forearm Surgery

The etiology of tourniquet pain is complex, and the study team hypothesizes that blocking with Interscalene brachial plexus block (ISBPB) is more efficient in decreasing the incidence of tourniquet pain in comparison with other techniques. As there is a paucity of studies that evaluate the effect of intercostobrachial nerve (ICBN) block and ISBPB and Patient-Controlled Analgesia (PCA) with a supraclavicular brachial plexus block (SCBPB) on tourniquet pain in forearm surgery, Therefore, we established this randomized study to compare ISBPB and ICBN and PCA with fentanyl with SCBPB in terms of the incidence and severity of tourniquet pain in patients undergoing forearm surgery.
