dc.description.abstract | Introduction: We present a case of an arterial blood gas sample analysis from a 33-year old woman where no oximetry results could be obtained using the Radiometer ABL800 FLEX device. Clinical history of this patient learned that she was carrier of a methemoglobin forming hemoglobin variant type Hyde Park (HbM Hyde Park) and raised the question whether or not this variant could be the cause of the errors obtained during analysis. Materials and methods: A literature search was performed, focusing on methemoglobin forming hemoglobin variants and their influence on oxygenation measurements. An overview of the currently described methemoglobin forming hemoglobin variants is also included. Results and discussion: In the presence of dyshemoglobins such as methemoglobin, techniques used to obtain parameters that reflect the patient oxygenation status, such as pulse oximetry and CO-oximetry can be influenced. In these cases, CO-oximetry is the preferred technique because it can compensate for this, in contrast to pulse oximetry. In case of the presence of methemoglobin originating from a hemoglobin variant, it is possible that COoximetry data cannot be calculated because the absorbance spectrum of this methemoglobin can differ from regular methemoglobin. Moreover, pulse oximetry devices are actually prone to erroneous results since pulse oximetry data will be calculated in these cases, but unreliable and should be avoided. Conclusion: Methemoglobin forming hemoglobin variants are rare genetic mutations. However, they can possibly interfere with the calculation of CO-oximetry values. In these cases, pulse oximetry data should be avoided because they could lead to incorrect medical decisions. | - |
