Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to evaluate the role of stellate ganglion blockade (SGB) for preserving arteriovenous fistula in hemodialysis patients undergoing major lower limb orthopedic surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The best way for dialysis in chronic renal failure (CRF) patients with consideration of feasibility, rate of infection, and patency is hemodialysis by using native access by using arteriovenous fistula (AVF).

Altered calcium and phosphor metabolism in CRF patients would also increase vascular reactivity. Stellate ganglion blockade (SGB) has been used for several years for both diagnosis and treatment of circulatory problems in upper extremity. Recently preemptive SGB has been used in prevention of radial artery spasm in coronary artery patients.

SGB increases blood flow and decrease vascular resistance in the arm. SGB prevents or ameliorates the reactivity of the muscular layer of the RA in response to both surgical manipulation during harvesting the artery and to the potent vasoconstrictor mediators released during surgery
