ABSTRACT
BACKGROUND:
Patients with thalassemia need regular blood transfusions to maintain normal growth and suppression of ineffective erythropoiesis. Packed red blood cell (RBC) units can be delivered by infusion pumps (IPs); however, IPs may cause mechanical stress-induced RBC lysis. This study aimed to investigate the biomarkers of hemolysis related to transfusion techniques in patients with thalassemia. MATERIAL ANDMETHODS:
Eighty-one thalassemia patients compared to those 42 healthy controls in terms of hemolysis markers (hemoglobin, plasma free hemoglobin (Hb), haptoglobin, potassium (K), lactate dehydrogenase (LDH)) before transfusion. Considering the age and peripheral venous diameter of the patient, the physician decided on the caliber of vascular access device (22 G or 24 G) for transfusion and the method to be used (gravitational method [GM] or IP). Hemolysis markers were repeated after transfusion in thalassemia patients.RESULTS:
Packed RBC units were transfused to 24 (30 %) patients by IP and 57 (70 %) patients by GM. Plasma free Hb was significantly increased from 4.76 ± 7.92 mg/dL to 9.01 ± 7.66 mg/dL following transfusion (p < 0.001). There was no significant difference between IP and GM in terms of plasma free Hb increase. Post-transfusion plasma free Hb, LDH, and K levels significantly increased in patients who were transfused with 24 G catheters compared to those transfused with 22 G.CONCLUSION:
An elevation in LDH levels was detected after transfusion with volumetric IPs; however, plasma free Hb or K levels were not affected by the transfusion method. Studies are needed to determine the factors associated with hemolysis after transfusion.Palavras-chave
