Abstract
Background: There are several dangers and adverse effects associated with red blood cell transfusions, which are often administered after surgery due to anemia. Our thesis is to assess the significance of hemoglobin level and subclinical iron insufficiency on perioperative morbidity and mortality in patients having heart surgery. Patients and Methods: This study conducted on 30 patients undergoing different cardiac surgeries during the period from May 1, 2021, and April 30, 2022. Results: Negative correlation between hospital length of stay and both hemoglobin and serum iron levels (r = -0.807, p 0.001). Patients who required a blood transfusion, developed an infection, had problems, were admitted to ICU, or died had substantially lower iron levels than the rest of the patients (p 0.001). Statistically significant association between Hb and the occurrence of problems (AUC = 0.994, p 0.001). The sensitivity is 100% and the specificity is 91.3%. Complications are strongly predicted by serum iron levels (AUC = 0.988, p 0.001). ICU admission may be predicted with high accuracy by Hb (AUC = 1.000, p 0.001). The sensitivity and specificity are both one hundred percent at a cut off value of 9. ICU admission can be predicted with a high degree of accuracy by serum iron levels (AUC=1.000, p0.001). The sensitivity and specificity are both one hundred percent at a cutoff value of 80. Conclusion: The results of cardiac surgery were worse for patients who had anemia prior to surgery.
