SII Levels Following iPACK Block With Adductor Canal Block in Knee Arthroplasty

Summary

This randomized controlled trial evaluates the effect of ultrasound-guided iPACK block with Adductor Canal Block (ACB) on the Systemic Immune-Inflammation Index (SII) in elderly patients undergoing total hip arthroplasty under spinal anesthesia. SII, calculated as platelet × neutrophil / lymphocyte count, is used as a composite marker of perioperative inflammatory and immune response. The study investigates whether iPACK block with ACB attenuates the systemic inflammatory reaction to surgical trauma compared to sham block.
