Occasional reviews Acute respiratory distress syndrome and nosocomial pneumonia

چکیده
The acute respiratory distress syndrome (ARDS) and nosocomial pneumonia share aetiological, physiopathological, and diagnostic properties that justify consideration of the relationship between these two diseases. The aetiology of ARDS can be separated into direct and indirect lung injury. In cases with indirect lung injury such as necrotising pancreatitis the cause of the lung injury may not be readily apparent, whereas in direct lung injury due to aspiration of gastric contents or pneumonia the role of infection is more clear. Sloane and co-workers, in a series of 153 patients, reported pneumonia as the underlying aetiology in 31% of all patients who developed ARDS. Furthermore, most patients with ARDS require mechanical ventilation which increases the risk of nosocomial pneumonia. This report reviews recent studies on the prevalence, incidence, and impact of nosocomial pneumonia on outcome in patients with ARDS.

Severe late-onset nosocomial pneumonia caused by Chlamydophila pneumoniae.
We report two cases of severe late-onset nosocomial pneumonia caused by Chlamydophila pneumaniae. The clinical course of the disease in these patients suggests that nosocomial pneumonia caused by this agent can lead to profound respiratory insufficiency and acute respiratory distress syndrome, particularly in patients with significant comorbidities and during the postoperative period. Intraveno...
متن کاملAcute respiratory distress syndrome and pneumonia: a comprehensive review of clinical data.
Acute respiratory distress syndrome (ARDS) and pneumonia are closely correlated in the critically ill patient. Whereas ARDS is often complicated by nosocomial pneumonia, pulmonary infection is also the most frequent single cause of ARDS. The prevalence of pneumonia during the course of ARDS seems to be particularly high, but whether persons with ARDS are more susceptible to pneumonia or simply ...

Influenza A(H1N1)pdm09-related pneumonia and other complications.
Influenza A(H1N1)pdm09 virus infection was associated with significant morbidity, mainly among children and young adults. The majority of patients had self-limited mild-to-moderate uncomplicated disease. However, some patients developed severe illness and some died. In addition to respiratory complications, several complications due to direct and indirect effects on other body systems were asso...
متن کاملDiagnosis of acute respiratory distress syndrome in nosocomial pneumonia.
Acute respiratory distress syndrome (ARDS) complicates nosocomial pneumonias (NPn) in 12% to 33% of patients with associated increases in mortality of up to 80%. A timely diagnosis of ARDS with NPn is, however, problematic. The aim of this investigation was to improve the diagnosis and treatment of the early stages of ARDS with NPn. A total of 82 cancer and multiple trauma patients were enrolle...
