The Impact of Vitamin C on Postoperative Acute Kidney Injury in Risk Patients Undergoing Valvular Heart Surgery

In cases of cardiac surgery or sepsis which cause inflammation, oxidative stress, endothelial injury and vasoplegia, serum vitamin C concentration is sharply decreased. The anti-inflammatory and anti-oxidant effects of vitamin C and the effects of reducing vasoconstrictor use have been demonstrated in patients with sepsis and septic shock, however, the foregoing effects have not been validated in patients undergoing cardiac surgery. In this study, investigators investigate the effect of intravenous vitamin C on the incidence of acute renal injury after valvular heart surgery.
