E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Check if oral hydration is at least as effective as intravenous hydration in reducing the appearance of contrast-induced nephropathy after performing a computed tomography with intravenous contrast in patients with renal insufficiency grade III. |
Comparar si la hidratación oral es al menos tan efectiva como la hidratación endovenosa en reducir la aparición de nefropatía inducida por contraste tras la realización de una tomografía computarizada con contraste endovenoso en pacientes con insuficiencia renal grado III. |
|
E.2.2 | Secondary objectives of the trial |
- Analyze the need for hemodialysis for one month after completion of computed tomography in patients who have undergone oral or intravenous hydration. - Analyze the reversibility of the contrast-induced nephropathy 15 days, in patients that have presented at 3 days post computed tomography, in both hydration groups - Assess safety in both groups hydration |
- Analizar la necesidad de hemodiálisis durante un mes tras la realización del TC, en pacientes que han seguido hidratación oral o endovenosa. - Analizar la reversibilidad de la NIC a los 15 días, en aquellos pacientes que la hayan presentado a los 3 días post TC, en ambos grupos de hidratación - Evaluar la seguridad en ambos grupos de hidratación |
