Your concerns are warranted. This is a scary series of events and, unless there have been signs of progressive improvement since your last report of November 26, one might question the appropriateness of discharging your daughter from the hospital, with the diagnoses of lung abscess and staph septicemia. I assume that your daughter’s antibiotic therapy is being managed by a pediatric infectious disease (ID) specialist; if not, you should seek such consultation. You would also want to ask the ID specialist if there might be an alternative antibiotic to vancomycin, such as linezolid, if that medicine were deemed appropriate for a 2½ year old child.
You should also consider getting another opinion regarding management of the lung abscess, which is probably the source of staph in your daughter’s blood. It is often difficult and sometimes impossible to eradicate a lung abscess, without surgical drainage. As the surgeon indicated, this would be a high risk procedure but a decision against surgery also carries risk. You should seek another opinion regarding treatment of the abscess from another surgeon and/or a pediatric pulmonologist and you should request that the pulmonologist, the ID specialist and the surgeon convene to discuss the pros and cons of the available and feasible approaches. Do not hesitate to request information or additional consultants, out of fear of offending your daughter’s physicians. There is too much at stake.
Finally you should ask her doctors if the infection might be due to an inherited or acquired immunodeficiency state.
