Abstract: Objective To study the clinical application value of hydration therapy based on the collapse rate of Inferior vena cava to prevent contrast nephropathy after interventional surgery. Methods A total of 460 patients undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI) in our hospital from November 2021 to November 2023 were selected and divided into control group (n=232) and observation group (n=228) according to random number table method. The control group received hydration therapy guided by traditional methods. The observation group was guided by the measurement of inferior vena cava collapse rate (CI-IVC). The serum creatinine (SCr), endogenous creatinine clearance (eGFR), serum homocysteine (CysC), urea nitrogen (BUN), hypersensitive C-reactive protein (hs-CRP) and serum N-terminal B-type natriuretic peptide precursor (NT-proBNP) of the two groups were compared before and after surgery. Total contrast agent, total hydration; Left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD). Contrast agent nephropathy. Results Before surgery, there was no statistically significant difference in the levels of SCr, eGFR, CysC, BUN, hs CRP, and NT proBNP between the two groups of patients (P>0.05). There was no statistically significant difference in LVEF and LVEDD between the two groups of patients (P>0.05). After surgery, the SCr, eGFR, CysC, BUN, hs CRP, NT proBNP water levels in the observation group were significantly higher than those in the control group (P<0.05). There was no statistically significant difference in the total amount of contrast agent between the two groups of patients (P>0.05). The total amount of hydration in the observation group was significantly higher than that in the control group, with statistical significance (P<0.05). The incidence of contrast-enhanced nephropathy in the observation group was significantly reduced compared to the control group, with a significant difference (P<0.05). Conclusion Guiding patients to do hydration therapy by measuring the collapse rate of inferior vena cava can effectively reduce the incidence of contrast agent nephropathy, which is of high application value and worth popularizing.

Key words: collapse rate of inferior vena cava, hydration therapy, contrast agent nephropathy
