The objective of this study was to evaluate the antioxidative properties of the multivitamin cocktail Omnibionta (alpha-tocopherol, ascorbic acid, retinol, vitamin B complex) in terms of diminishing lipid peroxidation with improvement of leg edema performance after limb revascularization operations in humans. Fifty-one subjects were selected; the control group contained 27 patients and the treatment group 24 patients, who received the vitamin cocktail intravenously before the start of reperfusion. All patients suffered from acute or chronic arterial occlusive disease, except two subjects with arterial trauma. MDA-TBARS in plasma, quantified by HPLC, taken as a measure of lipid peroxidation was significantly increased (p < 0.001) in the control group 1 hour after reperfusion onset and decreased to its baseline value within the following 2 hours (0.73 +/- 0.26, 1.21 +/- 0.48, 0.99 +/- 0.48, 0.73 +/- 0.33 nmol/ml). In contrast, in the treatment group MDA-TBARS did not exceed the baseline value during the reperfusion period (0.93 +/- 0.30, 0.70 +/- 0.29, 0.65 +/- 0.23, 0.70 +/- 0.37 nmol/ml). Leg edema, expressed by extremity circumference, was significantly (p < 0.008) elevated in the control group (30.7 +/- 4.04 cm versus 35.35 +/- 4.12 cm) compared to a lack of increase in the treatment group (29.25 +/- 5.13 cm versus 29.76 +/- 5.70 cm). These results suggest that antioxidative vitamin treatment might be valuable in preventing lipid peroxidation and decreasing extremity edema.
