Hello Katied,
This is a difficult question to answer. Typically, IV
antibiotics are used when there is failure of oral
antibiotics, the infection is spreading quickly or too severe to respond to oral
antibiotics.
MRSA is a bacteria that can live normally on the skin (termed colonization), particularly when there are items such as tracheostomies or g-tubes in place. if cultures are continually positive without signs of infection, this may be colonization. Often with colonization, repeated courses of
antibiotics do not clear the bacteria. This would not be a major issue except that the colonized bacteria occasionally can cause an overt infection.
If there is a significant infection that has been resistant to oral treatments it may be time for some IV
antibiotics. My best advice would be to discuss this with your child's doctor to see if IV
antibiotics may be of benefit.
Best wishes.
