Methemoglobinemia, Methaemoglobin, Pregnancy, Methylene blue


Methemoglobinemia is a rare form of functional anaemia which disrupts the ability to transport oxygen effectively by the haemoglobin leading to obstetrical as well as non-obstetrical complications. Our objective was to observe the antenatal, perinatal, and post-natal outcomes in women diagnosed with methemoglobinemia. A case report of two patients of methemoglobinemia admitted in a tertiary care centre of South Gujarat. The report displays a qualitative analysis of the diagnosis and management undertaken, providing a critical evaluation of their effectiveness and implications for future clinical practice. Methemoglobinemia, while uncommon, requires awareness for timely diagnosis and effective management. Congenital cases often go unnoticed until pregnancy, with methaemoglobin levels under 20% usually not necessitating treatment. Symptomatic individuals can benefit from methylene blue and hyperbaric oxygen therapies. Avoiding certain drugs and ensuring swift diagnosis, coupled with proper counselling, can lead to favourable pregnancy outcomes.
