Hi dear, I understand your concern, but in this case of antibiotic-resistant pneumonia, they need to perform throat or bronchial culture for flora and sensitivity to antibiotics, may be flora will sensitive to levofloxacin or gatifloxacin ,but we must be sure. If we have sensitivity then we can receive results. In addition, blood for Chlamydia,Mycoplasma pneumoniae, Cytomegalovirus should be checked .Also nebulisation is helpful and vibrational massage . Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing your baby good health.
