Incidence of contrast-associated acute kidney injury among stage 3-5 CKD patients after the risk assessment form used before contrast enhanced computed tomography in the Medical Department of Somdejphrajaotaksin Maharaj Hospital

Abstract

The objective of this study is to study the incidence of Contrast-Associated Acute Kidney Injury (CA-AKI) after the use of a CT scan, MRI risk assessments in patients with Stage 3-5 CKD who underwent computed tomography by injecting an opaque substance with an initial eGFR level of less than 60 ml/min/1.73 m2 between June 1, 2020 and June 30, 2021, at the Internal Medicine Department of King Taksin Maharaj Hospital A total of 46 patients analyzed the data with a statistical package, using descriptive and inferential statistics, the Wilcoxon Signed-rank test set a statistical significance level of 0.05, with the study finding a 10.9% incidence of CA-AKI, with the CA-AKI group having an average age of 66 years, and caused by congestive heart failure and chronic kidney disease. The average creatinine serum baseline is 2.21 mg/dl. The average eGFR baseline was 37.85 ml/min/1.73 m2, and 4 out of 5 patients with CA-AKI died in hospital, and when comparing the serum creatinine median of the sample, it was found that the group that obtained only normal saline had a median post-exposure of opaque substances equal to 1.65 mg/dl. Before exposure to opaque substances equal to 3.55 mg/dl. The median decrease was different at a statistically significant level (p-value < 0.05). There were 18 cases and an average percentage increase of 28.2%.
