Randomized Controlled Trial Multicenter StudyHydration with sodium bicarbonate does not prevent contrast nephropathy: a multicenter clinical trial.
Radiographic contrast media exposition can cause acute renal function impairment. There is limited and conflicting evidence that hydration with sodium bicarbonate prevents contrast-induced nephropathy (CIN) in patients undergoing cardiac catheterization. ⋯ Hydration with sodium bicarbonate was not superior to saline to prevent contrast media induced nephropathy in patients at risk undergoing cardiac catheterization.

Comparative StudyTransthoracic impedance compared to magnetic resonance imaging in the assessment of cardiac output.
Cardiac magnetic resonance imaging is considered the gold-standard method for the calculation of cardiac volumes. Transthoracic impedance cardiography assesses the cardiac output. No studies validating this measurement, in comparison to that obtained by magnetic resonance imaging, are available. ⋯ Transthoracic impedance cardiography proved accurate in the calculation of the cardiac output in comparison to cardiac magnetic resonance imaging.
