Thank you for your query.
Bluish discolouration of the lips (or cyanosis
) means reduced oxygen
in the blood. However this cannot be in your children as the discolouration is localised to the centre of the lips. There must be some other reason and as you mentioned it could be due to injury
. This can only be evaluated by a clinical examination.
I hope I have answered your query to your satisfaction.
Wishing your children an early recovery.
