Maternal and Neonatal Urinary Iodine Excretion and Neonatal TSH in Relation to Use of Antiseptic During Caesarean Section in an Iodine Sufficient Area

Abstract

Our data suggest that perinatal iodine exposure of full-term neonates who were born by Caesarean section in an iodine sufficient area did not influence neonatal TSH, although median UIE was higher, suggesting optimal iodine intake during pregnancy. Further research is needed to define a critical value of urinary iodine concentrations in full-term neonates in an iodine sufficient area that may lead to the impairment of thyroid function.
