Peripheral Artery Occlusive Disease, Popliteal Sciatic Nerve Block
Conditions
Keywords
regional oxigen saturation
Brief summary
We conducted Single-center prospective observational study to evaluate the improvement of peripheral vascular perfusion monitored with near-infrared spectroscopy, in patients undergoing endovascular surgery after performing sciatic nervous block.
Detailed description
The aims of that study is to check regional oxigen saturation variability in patients suffering from Peripheral Artery Occlusive Disease (IIa to III Fontaine classification) undergoing popliteal sciatic nerve block as analgesic procedure before vascular surgery. We want to evaluate the increase in regional microcirculation after the popliteal nerve blocks due to vasoplegic response and vasodilatation after performing regional anaesthesia. We will place NIRS electrode on the instep of the foot to evaluate regional oxigen saturation in the interested leg before the performing of popliteal sciatic nerve block and then during the surgery (after 5 minuts, 15 minuts, 30 minuts), and after the end of the procedure.
