Abstract

Background: Ultrasound (US) guided supraclavicular block (SCB) has the benefit of the widest sensory blocking of all of the brachial plexus techniques, including the single puncture method, due to the concentration of the plexus components at this site. Objectives: to assess the use of pulse oximeter perfusion index (PI) changes in assessment of success SCB in upper extremity surgery and to evaluate impact of adrenaline on pulse oximeter perfusion index changes. Patients and methods: A prospective, randomized, double-blind, comparative research was done on 90 cases between June 2022 to January 2023, at Al- Faculty of Medicine , Al-Al-Azhar University.

Results: there was a substantial distinction among the groups in Diagnostic accuracy of PI and PI ratio for the prediction of potent obstruct, change in HR in the time interval, Change in MAP in the time interval and Time to need analgesics in the time interval.

Conclusion: Pulse oximeter perfusion index changes and PI ratio can be used as reliable predictors of success of SCB in upper extremity operation. However, epinephrine produces no difference in perfusion index compared to local anesthetic alone.
