A near-term infant became unwell immediately after birth with cardiorespiratory compromise—persistent tachycardia, pulmonary hypertension and reduced cardiac function. There had been no concerns during the pregnancy and the obstetrical and maternal medical history was unremarkable apart from hypothyroidism. A thyroid function test on admission revealed a significantly elevated free T4 and a diagnosis of a thyroid storm was made. On questioning it became apparent that she had Graves’ disease after her last pregnancy and was rendered hypothyroid post surgery, she was not aware of the relevance of this at her booking visit. This case highlights the importance of monitoring of women who have a history of a diagnosis of Graves’ disease, regardless of thyroid function status, to allow for appropriate antenatal monitoring, preparedness of the NICU (neonatal intensive care unit) team and correct follow-up of the neonate. It also demonstrates the importance of ensuring a patient is properly educated about their condition.
