This study was conducted in patients with acute myocardial infarction who undergo emergency PCI in Chinese PLA General Hospital. The patients were randomly divided into two groups: the adequate hydration group guided by Vigileo and control group. For the adequate hydration group guided by Vigileo, Vigileo equipment is used to perform hemodynamic monitoring through the femoral or radial arteries to obtain relevant hemodynamic parameters (CO, SV, SVV), and the fluid-rehydration velocity of normal saline is adjusted according to the hemodynamic parameters, and the hydration also lasts 24 hours after operation. For the control group, the routine hydration regimen is adopted, perioperative saline ≤500 ml hydration. The changes of renal function (serum creatinine, serum cystatin), symptoms and signs of cardiac insufficiency during perioperative period and cardiac objective indexes are observed. The incidence of postoperative acute pulmonary edema is recorded, and the major cardiovascular events and hemodialysis events are followed up for 6 months. By comparing the perioperative indexes of heart and kidney function between the intervention group and the control group, the preventive effect of adequate hydration guided by Vigileo on contrast induced nephropathy after PCI was clarified.
In this study, Vigileo is used to guide hydration adjustment, and SCr is used to estimate renal function. The aim of the study is to investigate the preventive effect of adequate hydration guided by Vigileo on contrast induced nephropathy in patients with acute myocardial infarction who undergo PCI.
