Abstract
The main aim of this study was to examine the association of glucose and sodium level with diagnosis and disease outcome of critically ill patients. Glucose and sodium concentrations of 283 patients admitted in critical condition to the Intensive Care Unit of the Department of Internal Medicine in a period from November 1, 2015 to February 28, 2017 were reviewed. The most common diagnoses in critically ill patients were acute kidney injury (26.1%) and sepsis (including septic shock, 22.3%). Significantly lower glucose concentration was observed in patients with acute kidney injury (p=0.02), whereas patients in sepsis and septic shock had a significantly higher sodium concentration (p=0.04). Higher glucose level was related to higher mortality rate (p=0.001). On the other hand, sodium level was not significantly associated with survival. Higher mortality, as well as higher glucose concentration were more common in patients older than 65 years (p<0.001). Study results showed significantly lower glucose concentrations in patients with acute kidney injury, whereas in patients older than 65, glucose concentration was significantly higher. Patients in sepsis and septic shock had significantly higher sodium concentrations. Higher concentration of glucose was connected with higher mortality in the elderly, whereas sodium concentration did not show connection with mortality.
