Are the perfusion & #304;ndex and pleth variability index title an early & #304;ndicator of brachial plexus block ?

Conclusion: In our study, we observed an increase in PI from the 1st minute compared to the non-blocked arm in successful block applications. We consider the early indicator of PI in the evaluation of block success. In our study, we did not observe a significant change in the arm that was blocked and the arm that was not treated with PVI.
