Treatment of pulmonary infection of extensively drug-resistant Acinetobacter baumannii with intravenous colistin sulfate combined with atomization: a case report

: Extensively drug-resistant Acinetobacter baumannii (XDRAB) pulmonary infection is a serious respiratory system infection. Patients are often very sick and even need to be admitted the ICU for treatment. In this case report, we presented our treatment experience of one XDRAB patient. A 71-year-old male patient was hospital complaining “fatigue accompanied by fever 2 days shortness breath 1 day”. The patient’s admission diagnosis as follows: severe pneumonia, acute distress syndrome, I type failure, septic shock, cardiac insufficiency, liver hypertension. Imipenem/cilastatin sodium combined with moxifloxacin were first applied. Then, tigecycline, imipenem/cilastatin caspofungin used. drug sensitivity results suggested that strain sputum culture sensitive polymyxin only. Thus, colistin sulfate cefoperazone/sulbactam medication process monitored. We found intravenous injection aerosol route effective in infection, no adverse reactions observed during anti-infection therapy nebulization could good choice lung infections.
