Abstract

Intravenously administered iodine-containing contrast medium (CM) is associated with the development of contrast-induced nephropathy (CIN). Data on the effectiveness of sodium bicarbonate therapy in the prevention of CIN are controversial. Furthermore, the incidence of and risk factors for CIN in intensive care unit (ICU) patients are poorly defined. We investigated the effectiveness of sodium bicarbonate prophylaxis and the incidence of and risk factors for CIN in a heterogeneous ICU population.This retrospective cohort study included patients admitted to the ICU in 2009-2011 who received CM for computed tomography (CT).Two hundred eleven CT scans with CM, performed in 170 patients, were included in the study. Contrast prophylaxis with sodium bicarbonate was administered in 48 of the 211 cases. CIN developed in 19 of the 48 cases receiving prophylaxis and in 39 of 163 cases not receiving prophylaxis (p?=?0.03). In 115 CTs performed in patients with a glomerular filtration rate (GFR) >60?mL/min, prophylaxis was administered 15 times (13?%) and no prophylaxis was administered 100 times (87?%). CIN developed in 12 and 13?% of these cases, respectively (NS). In 96 CTs in patients with a GFR
