Measurements of plasma creatinine - equivalent to serum creatinine - were utilized to classify sufferers as either AKI or non-AKI according for the serum creatinine criteria within the AKIN classification [3,10]. We didn't involve the urine output criteria. The phrase AKI incorporated all AKIN phases, and was even more subdivided in accordance to your individual AKIN phases. For every patient, a pre-operative blood sample was collected 10 days just before surgical treatment. Accordingly, the baseline creatinine was readily available for all study participants. The peak post-operative measurement of creatinine from surgical treatment commence till day 5 was in contrast to baseline creatinine to assign AKI status.Review endpointsInformation on all-cause death was obtained by linkage to the Danish Civil Registration Method .
