Abstract :Objective: To investigate the potential relation between dynamic thiol homeostasis and blood transfusion in the pediatric intensive care unit. Methods: Blood samples were collected from pediatric intensive care patients before and after erythrocyte suspension transfusion and from donor blood additionally to measure thiol levels. The study involved 30 patients, including nine females, and a total of 90 blood samples from patients and donors were analyzed. Results: Prior to transfusion, Total Thiol (TT) and Native Thiol (NT) were 414.77 ± 156.14 (μmol/L) and 272.63 ± 115.75 (μmol/L), respectively, and post-transfusion, they were found to decrease to 398.07 ± 187.38 (μmol/L) and 258.97 ± 136.2 (μmol/L), respectively. However, no statistically significant difference was observed between pre- and post-transfusion values. In post-transfusion blood samples, there was a significant increase in Disulfide/TT and Disulfide/NT ratios, indicating an increase in oxidation (34.79 ± 92.34 and 51.89 ± 68.51, respectively), yet no statistical difference was noted. Conclusion: Transfusions administered in the Pediatric Intensive Care Unit were associated with a decrease in total and native thiol levels, indicative of increased oxidative stress, despite the lack of statistically significant differences. To mitigate the potential negative impact on patients with high oxidative properties after transfusions, strengthening the antioxidant defense system is recommended. Research should be planned to develop suitable strategies for enhancing the antioxidant defense system and ensuring patients\' resilience to this condition.Keywords : çocuk, eritrosit süspansiyonu transfüzyonu, pediatrik yoğun bakım, dinamik tiyol homeostazisi
