    The study assessed the peripheral perfusion index (PI) as a predictor for the effectiveness of femoral nerve block in knee surgery.

  • 2

    A total of 78 patients with knee meniscus injuries were included, all classified as ASA physical status I or II.

  • 3

    The area under the ROC curve for PI at T6 on the blocked side was 0.993, indicating high sensitivity and specificity.

  • 4

    Significant differences in PI values were observed between the blocked and non-blocked sides, with a cut-off value of 1.755.

  • 5

    The findings suggest that PI is a reliable method for assessing FNB success, aiding anesthesiologists in optimizing patient care.
