Part Description

LP15729-4 Methemoglobin
Methemoglobin is a form of the oxygen-carrying protein hemoglobin, in which the iron in the heme group is in the Fe3+ state, not the Fe2+ of normal hemoglobin. Metheomglobin appears blue and is unable to carry oxygen. The NADH-dependent enzyme methemoglobin reductase (AKA diaphorase I) is responsible for converting methemoglobin back to hemoglobin. Normally 1-2% of people's hemoglobin is methemoglobin, a higher percentage than this can be genetic or caused by exposure to various chemicals and depending on the level can cause health problems. A higher level of methemoglobin will tend to cause a pulse oximeter to read closer to 85% regardless of the true level of oxygen saturation. Methemoglobinemia can be caused by genetic abnormalities such as diaphorase I deficiency, or abnormal hemoglobin variants. It can also be caused by certain oxidizing drugs (benzocaine), antibiotics (trimethoprim or sulfanamides), analine dyes, metoclopramide, chlorates, bromates, and nitrates. Infants under 6 months are particularly susceptible when exposed to nitrates, benzocaine, or even dehydration. Methemoglobinemia can be treated with supplemental oxygen and methylene blue.
