AbstractMechanical ventilation is a well-established and commonly employed modality of treatment for critically ill patients in the ICU. Pneumonia is a frequent complication in mechanically ventilated patients. Patients who develop ventilator-associated pneumonia (VAP) incur higher medical costs, have prolonged ICU and hospital stays, and have increased mortality risk. There is growing interest in finding new treatment modalities for this condition because the success rate for treating VAP with systemic antibiotics continues to be < 70%. Accordingly, clinicians are reevaluating the role of aerosolized antibiotics, either as a sole therapy or as adjuncts to systemic antibiotics, in an attempt to improve clinical outcomes in patients with VAP. There are several clinical settings in which aerosolized antibiotics could be used for treating pneumonia, including their use for prevention, as monotherapy, as adjunctive therapy with systemic antibiotics, and for treatment of extensively drug-resistant or pan drug-resistant pathogens. However, aerosolized antibiotics have not been uniformly effective for improving clinical outcomes of patients with VAP, and local and systemic side effects could complicate their use. Moreover, many questions about aerosolized antibiotics, such as optimal formulations and dosage and treatment regimens, remain unanswered and warrant future investigations.Copyright © 2019 by Daedalus Enterprises.
