Introduction: The specific impact on calcium dynamics after non-massive blood transfusions remains relatively unexplored. This study aimed to compare pre- and post-transfusion calcium levels in patients receiving blood and blood product in the emergency department. Methods: This is a single-center, prospective, cross-sectional study conducted at the Emergency Department of Gazi University Health Research and Application Center Hospital in Ankara, Turkey, from January 1, 2020, to August 31, 2020. The study included adult patients who underwent blood and blood product transfusions, and serum calcium levels were measured and compared from samples taken before and after transfusion. Results: A total of 292 participants were enrolled in the study, with 242 participants included in the final analysis. The mean total calcium level was 8.41 ± 0.76 mg/dL before transfusion and 8.34 ± 0.71 mg/dL after transfusion (p=0.012). When examining the corrected calcium values after receiving blood products based on the type of blood products, participants who received apheresis platelets had a post-transfusion corrected calcium value of 8.26 ±0.41 mg/dL, with a pre-transfusion value of 9.09 ±0.49 mg/dL (p |
