Absorption of iodine in the neonate following topical use of povidone iodine

Abstract

Topical application of povidone iodine on the umbilical cord and normal intact skin of newborn infants resulted in significantly elevated plasma iodine levels. High iodine levels were also found in two neonates who had povidone iodine applied to denuded skin. No significant alteration in thyroid function was seen. The possible toxic manifestations of high plasma iodine levels are discussed.
