Effect of Subarachnoid Block and Femoropopliteal Block to Limb Perfusion in PAD Patients

Summary

This pilot study investigates the effects of femoropopliteal and subarachnoid nerve blocks on tissue oxygen saturation (StO2) in patients with Peripheral Arterial Disease (PAD) during lower limb surgeries. Using Near-Infrared Spectroscopy (NIRS), the study compares changes in StO2 post-block. Although no significant differences were found between the two block types at most time points, subarachnoid blocks generally led to higher StO2 increases compared to femoropopliteal blocks, with significant differences observed at 5 and 15 minutes post-block.
