The infraclavicular nerve block, which is frequently preferred in upper extremity surgeries, provides additional advantages such as reduction in opioid consumption by providing analgesic effect in the postoperative period as welll. The success of peripheral nerve blocks is usually assessed by subjective feedback from the patient, and patient cooperation is needed. The aim of this study is to assess whether the perfusion index level, which can be measured noninvasively, can be a predictor of the infraclavicular block success.
