Why should iodophor be used cautiously in neonates?

Using iodophor cautiously in neonates is crucial because it can lead to hypothyroidism. Iodophors, which are a combination of iodine and a solubilizing agent, are commonly used as antiseptics due to their broad-spectrum antimicrobial activity. However, in neonates, especially those who are premature or have underdeveloped thyroid function, exposure to high levels of iodine can interfere with normal thyroid hormone synthesis. This interference may inhibit the production of thyroid hormones, leading to thyroid dysfunction and the potential development of congenital hypothyroidism.

It's important to be mindful that while other factors associated with iodophors, such as skin rashes or allergic reactions, may pose risks, the specific risk of hypothyroidism due to iodine exposure is particularly significant in this vulnerable population. Additionally, although issues like dehydration can occur from other medical conditions or interventions, they are not directly related to the use of iodophors. Thus, attention to iodine levels is key in preventing potential endocrine complications when treating neonates.
