Abstract
|
|
|
Background: To evaluate the accuracy of a portable hemoglobin photometer, the HemoCue, during surgery, hemoglobin concentrations (Hb) of HemoCue were compared with those of the SYSMEX XE-2100, in the situation of bleeding.
Methods: Hemoglobin concentrations were measured with HemoCue and by the SYSMEX XE-2100 at the same time, on 100 blood samples obtained from patients who were bleeding more than 500 ml, during surgery. The limits of agreement between the two methods were calculated from the results according to the method of Bland & Altman. The results of HemoCue were adjusted by adding the mean bias, defining the corrected values, and reevaluated the agreement with the results of the SYSMEX XE-2100.
Results: The differences in results between the two methods were 1.12 ± 0.37 g/dl. The limits of agreement were 0.38?1.86 g/dl, which means disagreement between the two methods. However, the corrected values represented agreement with the values of the SYSMEX XE-2100. The limits of agreement were ?0.74?0.74 g/dl.
Conclusions: The corrected Hb values of HemoCue were comparable to the values of SYSMEX XE-2100. It is useful to evaluate the hemoglobin concentration using HemoCue intraoperatively.
