Abstract
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. Lipid peroxide level and serum total antioxidant capacity (TAC) were measured before anesthesia induction and one hour after surgery. As the normal range, the findings obtained from 23 healthy volunteers were utilized. RESULTS: ean age was 54.9±11.21 and 52.4±11.23 years in the spinal anesthesia (SA) and the general anesthesia (GA) group, respectively (P=0.49). Serum TAC in GA group increased from 1.03±0.04 mM to 2.98±0.7 mM. In SA group, the increase of serum TAC from 1.22±0.11 mM to 3.42±0.5 mM was observed that indicated the increase of serum TAC in both groups was not significantly different (P=0.21). Serum Malondialdehyde (MDA) in GA and SA groups did not show a significant difference before surgery (31.14±3.9 mM vs. 29.06±2.49 mM in GA and SA groups, respectively) (P=0.31), while it was significantly different after surgery (23.14±2.6 mM and 19.24±2.7 mM in GA and SA groups, respectively) (P=0.03). CONCLUSION: lower limb amputation can help to control oxidative stress in diabetic patients; and considering serum MDA as a marker of oxidative stress, SA seems to be more effective to control this problem.
