The aim is to evaluate the success of reduction procedures and pain palliation in patients with forearm fractures undergoing reduction under procedural sedation-analgesia (PSA) and ultrasound (US)-guided infraclavicular nerve block (ICB) in the emergency department.

Forearm fractures are among the most frequent reasons for adults to visit the emergency department. These fractures cause significant pain both due to the fracture itself and during the reduction process. Pain management in emergency departments (ED) is crucial. Therefore, multimodal approaches are available to reduce or eliminate pain during the reduction process. The aim of this study is to evaluate the success and pain palliation of the reduction process with procedural sedation-analgesia (PSA) and with reduction under ultrasound (US)-guided infraclavicular nerve block (ICB) in patients with forearm fractures. The secondary aim is to compare patient comfort, physician comfort, side effects, length of stay in the emergency department, and the need for painkillers after discharge between these two procedures, and to identify the most suitable method. This study aims to contribute to practical applications in order to provide optimal pain control in patients with forearm fractures in emergency departments.

Patients' pain levels at arrival, pre-reduction procedure, and post-reduction procedure will be recorded using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain).The success of the reduction procedure, whether further reduction attempts were necessary, and findings from post-reduction control X-rays (radial height, radial tilt, and volar tilt) will be noted and evaluated by orthopedic physicians.
