Limited effects of micronutrient supplementation on strength and physical function after abdominal aortic aneurysmectomy.

Background: Tissue injury following ischemia-reperfusion is mediated in part by free oxygen radicals. We hypothesized that perioperative micronutrient supplementation would augment antioxidant defenses, minimize muscle injury, and minimize postoperative decreases in muscle strength and physical function following abdominal aortic aneurysmectomy.

Setting: A university-affiliated hospital and regional referral center.
