The Effect of Different Regional Blocks: Combined Femoral-Sciatic, Spinal and Epidural Blocks on the Different Side Effects of Arterial Tourniquet in Patients Undergoing Lower Limb Orthopedic Surgeries —A Randomized Controlled Trail

Abstract: Background: Pneumatic arterial tourniquet is a very commonly used technique in limb surgeries to provide bloodless field to facilitate dissection and decrease blood loss. However, arterial tourniquet has many deleterious effects including hemodynamic changes, serum lactate and potassium level changes and tourniquet-induced pain which sometimes can be severe and intolerable. Aim of the study: To evaluate the effect of different regional blocks: femoralsciatic, spinal and epidural blocks on serum lactate and pot… Show more

“…One of the mechanisms involved is a progressive decrease in super oxide dismutase with mitochondrial dysfunction. In humans, according to Omar [16], Oragui [15], and Van der Spuy and et al [51], tourniquet exposure times exceeding 2 hours are responsible for systemic ischemic phenomena. In the opinion of the same authors, the plasma marker levels of IR.…”
