A case report of neonatal thyrotoxicosis due to maternal autoimmune hyperthyroidism.
A case of neonatal thyrotoxicosis secondary to maternal autoimmune hyperthyroidism is reported in an infant born at 34 weeks gestation who presented with tachycardia, jitteriness, diarrhea, and a small goiter. Propranolol and oxygen were used to treat high-output cardiac failure and transient persistent pulmonary hypertension. The infant's response to propylthiouracil therapy, gradual resolution of cardiac and systemic symptoms, and normaliziation of thyroid studies are described. Thyroid physiology and function and the special considerations in a premature infant are reviewed. An overview of maternal autoimmune hyperthyroidism and the implications for the developing fetus and neonate are presented. The risk factors for, and clinical presentation of, hyperthyroidism are outlined and treatment strategies highlighted. The nursing care of infants with hyperthyroidism is carefully described with an emphasis on the surveillance for and management of multisystem manifestations.
