Most patients recover rapidly and are liberated from mechanical ventilation during this phase. Acute Respiratory Distress Syndrome (ARDS) — Phases and Treatment See online here Acute respiratory distress syndrome (ARDS) is a severe inflammatory reaction of the lung that is characterized by the presence of pulmonary infiltrates due to alveolar fluid accumulation, without evidence suggestive of a cardiogenic etiology. ARDS has three phases: the acute exudative phase (injury), proliferative phase (reparative), and fibrotic phase (chronic phase) (Arbour, 2017; Gordon & Ennis, 2017). The initial phase of ARDS begins 1-7 days after injury, with a systemic immune response that triggers the release of inflammatory mediators called cytokines. ARDS can be self limited with a rapid recovery over several days with complete resolution.

Yet, for the busy clinician, the value of knowing the spilling of cells and cytokines may feel far-flung; the ‘ wisdom’ of the molecular mechanisms being divorced from the ‘ madness’ of clinical practice. Fibroproliferative Phase of ARDS. Most patients with adult respiratory distress syndrome (ARDS) survive the initial insult which caused respiratory failure only to succumb later to sepsis caused by nosocomial pneumonia or to pulmonary fibrosis. The clinical features depend on the pathological changes of ARDS, which encompass 3 phases: exudative, proliferative, and fibrotic. 1. Exudative phase.

Acid aspiration. Pneumonia. Acute respiratory distress syndrome (ARDS) is a major clinical problem in critical care medicine, with an incidence of 78.9 per 100,000 person-years in the United States ().Furthermore, between 1999 and 2013, approximately 156,000 patients died of ARDS in the United States ().Survivors suffer from long-term consequences including long-term physiological and cognitive impairment ().

The proliferative or regenerative phase follows, characterized by gradual reduction of the inflammatory process, includes proliferation of type II pneumocytes as part of the reparative process. This phase occurs if the alveolar collagen that is deposited during the acute exudative phase fails to be resorbed, resulting in limitations of alveolar expanse and subsequently gas exchange. Causes/Mechanism. It is important to note that DAD can occur in settings other than ARDS and that ARDS can occur with histology other than DAD. Das Acute Respiratory Distress Syndrome (ARDS) ist eine massive Reaktion der Lunge auf diverse schädigende Faktoren und geht mit einer schweren Einschränkung der Oxygenierung einher.

1). During the proliferative phase the pulmonary edema resolves, and surfactant is being produced again. This phase lasts one to three weeks. Intra-alveolar exudate turns into a cellular granulation tissue and worsens the hypoxemia.

Vascular lesions include thrombotic, fibroproliferative, and obliterative changes, which, like the parenchymal lesions, correlate with the temporal phase of diffuse alveolar damage. Histopathologically, three phases are recognised during the evolution of ARDS: 1) an exudative early phase which results from diffuse alveolar damage and endothelial injury; 2) a proliferative phase which ensues about 7–14 days after the injury, incorporating repair of the damaged alveolar structure and re-establishment of the barrier function, together with proliferation of fibroblasts; 3 2016-11-19 2002-06-01 Acute respiratory distress syndrome (ARDS) is defined as the onset of acute hypoxemia within 7 days of a known clinical insult or new or worsening respiratory symptoms with bilateral opacities (patchy, diffuse, or homogenous) consistent with pulmonary edema on imaging. The exudative phase is defined by capillary congestion and intra-alveolar oedema, and is maximum during the first week after the onset of ARDS. The second phase, proliferative, is a phase of repair marked by intense cellular proliferation, especially of alveolar type-2 cells and fibroblasts. Our findings, and those of others, have shown that the fibroproliferative phase of late ARDS gives rise to an inflammatory syndrome manifesting with fever, leukocytosis, low systemic vascular resistance, diffuse alveolar infiltrates, diffuse and intense bilateral pulmonary uptake of gallium, and BAL neutrophilia. Although ARDS frequently culminates in "interstitial" fibrosis, the organization of intraluminal exudate dominates the histologic picture in the proliferative phase and establishes the framework for subsequent fibrous remodeling of the lung. In the proliferative phase, type II cells multiply to reconstitute the alveolar lining and an interstitial inflammatory infiltrate of mononuclear cells is accompanied by proliferation of fibroblasts.
