There is significant evidence to suggest that topical application of chlorhexidine to umbilical cord reduces neonatal mortality and omphalitis in community and primary care settings in developing countries. It may increase cord separation time however, there is no evidence that it increases risk of subsequent morbidity or infection.
There is insufficient evidence to support the application of an antiseptic to umbilical cord in hospital settings compared with dry cord care in developed countries.
Umbilical care and cord separation.
Four different treatments for the care of the umbilical cord were compared in a randomised, controlled study. Triple dye was associated with a significantly earlier separation of the cord than either 1% neomycin or 1% silver sulphadiazine ointment, and it was nearly as effective as bismuth subgallate (an astringent powder) in causing rapid sloughing. If the mother is made aware that care of the umbilical cord may delay cord separation she may be spared unnecessary concern.
