Abstract
Background and objectives:  Intraoperative blood transfusion is a common medical intervention worldwide. Although mostly lifesaving when indicated, inappropriate administration of intraoperative can be potentially life-threatening. The aim of this study was to analyze the most common surgery/invasive procedures requiring intraoperative transfusion and to determine indications for intraoperative transfusion as well as the outcome of the patients after intraoperative transfusion.
Methods: A retrospective review of the electronic database of medical records was done for surgical patients who received intraoperative transfusion from June 2019 to December 2019. Preoperative hemoglobin values, associated comorbidities, and physiological triggers including hypotension and tachycardia were recorded. Descriptive statistics were used to summarize the data.
Results: A total of 36 patients (age range: 9-80 years) were studied. Orthopedic surgeries (53%) were the most common surgeries that required intraoperative transfusion. Preoperative anemia (hemoglobin <10 g/dl) was the predominant reason for intraoperative transfusion. Type 2 diabetes mellitus (36.3%) was the most frequent comorbidity among the cases of intraoperative transfusion. Half the cases received two units of packed red blood cell (pRBC), while 39% of the cases received one unit of pRBC. The remaining 11.1% received more than two units of pRBC. Furthermore, 77.7% of the patients were discharged to home within a week, while 16.6% of the patients were discharged after a prolonged hospital stay (> one week). The remaining 5.5% died in the hospital within a week of the procedure/surgery.
Conclusion: Transfusion practices vary among physicians, hospitals, and countries. The findings highlight that the hospital might be the most important determinant of the number of administered transfusions, with some adopting programs to reduce transfusions for elective surgery.

Abstract
Background: Bivalent minerals function as crucial cofactors that participate in a multitude of metabolic pathways within the organism. Specifically, zinc (Zn) assumes catalytic, structural, and regulatory roles in numerous biological processes. A severe deficiency in Zn can lead to disruptions in nucleic acid and protein synthesis, impaired cellular proliferation, increased apoptosis, and heightened lipid peroxidation of cellular membranes, a phenomenon associated with a reduced lifespan of red blood cells (RBCs). The objective of this study was to investigate the correlations between Zn status and various erythrocyte indices in a cohort of anemic patients, in comparison to a control group.
Methods: A cohort of 563 participants was enrolled in this investigation. Serum Zn concentration was quantified using a BT-3500 autoanalyzer, while hematological indices were determined via a Sysmex KX21N cell counter. Following confirmation of data normality, Spearman's rank correlation coefficient was employed to analyze the relationship between serum Zn levels and RBC indices.
Results: The mean serum Zn concentration was 102.8 ± 17.6 mg/dL. Serum Zn levels exhibited a weak correlation with RBC and hemoglobin (Hb) concentrations in healthy women, as well as a weak correlation with mean corpuscular hemoglobin concentration (MCHC) in anemic men (p < 0.05). Furthermore, the results indicated significantly higher serum Zn levels, RBC, Hb, hematocrite (HCT), and MCHC in men (p < 0.01), while mean corpuscular volume (MCV) was significantly higher in women (p < 0.01). Notably, in individuals with serum Zn levels < 30 mg/dL, MCHC (p < 0.01) and RBC (p < 0.05) were elevated, whereas Hb (p < 0.05), HCT, MCV, and MCH (p < 0.01) were higher than 30.
Conclusion: Considering the potential impact of varying Zn concentrations on erythrocyte indices, including Hb and MCHC, in both healthy and anemic individuals, careful regulation of its dosage is warranted.
