The Effect of Spinal and General Anesthesia on Serum Lipid Peroxides and Total Antioxidant Capacity in Diabetic Patients with Lower Limb Amputation Surgery.

Background: Anesthesia is performed in two major methods including regional and general.The aim of this study was to compare the effect of anesthesia method (spinal and general) on oxidative stress in diabetic patients underwent diabetic amputation surgery.

Methods: In this randomized control trial, 40 patients with diabetic foot who were candidate for foot amputation surgery at our academic hospital in 2013, were selected and divided into two groups based on anesthesia method.

Effect of low dose aspirin and dipyridamole on primary patency of arteriovenous grafts in hemodialysis patients: a randomized double-blind placebo-controlled trial.

Background: There is some evidence for the efficacy of antiplatelet therapies in increasing the vascular access patency duration or decreasing the thrombosis of arteriovenous grafts.

Objective: To determine the effect of low dose aspirin and dipyridamole on primary patency of arteriovenous grafts in hemodialysis patients.

Methods: This randomized, double-blind, placebo-controlled trial was done at Imam Reza Hospital in Mashhad, Iran from September 10, 2015 to July 05, 2016.
