Background and objectives: Preoperative anxiety is an enormous feeling of fear that is seen in all patients undergoing surgery. The severity of anxiety may vary depending on the type of surgery and anesthesia to be performed. The aim of this study is to compare the effects of brachial plexus blocks and general anesthesia methods on preoperative anxiety levels in patients who will undergo orthopedic upper-extremity surgery and to determine the factors affecting anxiety. Materials and Methods: After randomization, the Amsterdam Preoperative Anxiety and Knowledge Scale (APAIS) questionnaire was applied to the patients to determine the preoperative anxiety level, and then anesthesia was applied according to the anesthesia type determined. Pain scores (1, 8, 16, and 24 h) and total opioid consumption of the patients were recorded postoperatively. Results: The APAIS score of the patients in the general anesthesia (GA) group was significantly higher (p = 0.021). VAS score medians at 1, 4, and 8 h postoperatively were found to be significantly higher in the GA group (p < 0.001, p < 0.001 and p = 0.044, respectively). Conclusions: USG-guided BPB may cause less anxiety than GA in patients who will undergo elective upper-extremity surgery. However, these patients have moderate anxiety, although it is more associated with advanced age, female gender, and education level.
