Comparison of serum corrected and ionized calcium levels in patients with acute kidney injury

Abstract

Introduction: Acute kidney injury (AKI) is common in hospitalized patients (1.92%). The effect of serum corrected and ionized calcium levels in predicting emergency hemodialysis in patients with AKI is unknown. In this study, we aimed to compare serum corrected and ionized calcium levels in patients who were diagnosed with AKI in the emergency service. Methods : Our study was planned retrospectively. Group 1: Patients with AKI who underwent at least one session of emergency hemodialysis. Group 2: The patients with AKIN stage 1-3 who did not undergo hemodialysis. Serum corrected and ionized calcium, creatinine and albumin values of the patients at the time of admission were analyzed. All data of the study were recorded by SPSS 19.0. For statistical significance, p <0.050 was accepted. Results : The mean serum corrected calcium levels were lower in group 1 than in group 2, and the difference was statistically significant (p <0.001). The mean ionized calcium levels in blood gas were lower in group 1 than in group 2, and the difference was statistically significant (p = 0.002). Conclusions : Serum corrected, and ionized calcium levels can be useful in predicting emergency hemodialysis in patients with AKI. were lower than that of those who did not undergo hemodialysis [10]. This retrospective study showed similar results. It that serum corrected and ionized calcium levels of the patients with AKI who referred to the emergency unit and received hemodialysis based on clinical indications were lower than that of the patients who did not undergo hemodialysis. In our study, when patients with serum creatinine> 4mg/dL due to acute renal failure were divided into two subgroups as dialysis (group 1a) and non-dialysis (group 2a), serum creatinine levels were higher in group 1a and corrected calcium levels were higher in group 2a patients. The groups were found to be similar in terms of serum albumin and ionized calcium levels. The findings of our study are compatible with the literature. As an exception, ionized calcium levels were found to be similar in both subgroups, the lower ionized calcium levels of group 1a patients than group 2a patients, although reaching significance,
