Review Comparative Study
[Guidelines for treatment of pneumonia in intensive care units].
Patients affected by pneumonia can be admitted in Intensive Care Units (ICUs) independently by the setting where the infection has been acquired (community, hospital, long-term care facilities); even more frequently pneumonia can develop in patients already hospitalized in ICU especially in those requiring mechanical ventilation for different reasons. Within the severe community acquired pneumonia requiring admission in ICU, the most frequently responsible micro-organisms are mainly represented by Streptococcus pneumoniae, but also by Legionella and Haemophilus. Pseudomonas aeruginona, anyway, cannot be excluded. ⋯ Late onset VAP and HAP in patients with risk factors for multi-resistant, by contrast, should be treated with a combination therapy: in case of defined or suspected P. aeruginosa, Klebsiella pneumoniae (ESbL+), Acinetobacter sp etiology, it is required the use of an anti-pseudomonas cephalosporin or an anti-pseudomonas carbapenem or b-lactam + beta-lactamase inhibitor associated with an anti-pseudomonas fluoroquinolone or an aminoglicoside. The possible presence of MRSA or Legionella pneumophila suggests the use of anti-Gram positive antibiotics such as glycopeptides or linezolid. These quidelines confirm the role of ciprofloxacin combined with beta-lactams whenever P. aeruginosa, Klebsiella pneumoniae (ESbL+), Acinetobacter sp. etiology is suspected.
