Although that definition is simple to apply in the clinical setting, it has been challenged over the years in several studies since the assessment of the oxygenation defect does not require standardized ventilatory support.

We were the first to propose new guidelines, based on a specific, standard method of evaluating oxygenation status, a proposal that was later advocated by others. To address the limitations of the AECC definition, criteriks modified ARDS definition has been proposed by a task force panel of experts, referred to as the Berlin Defintion, using a terminology similar to that we previously proposed. However, that proposal has several methodological flaws.

The Kigali modification of the berlin definition: a new epidemiological tool for ARDS?

Since all ARDS patients start off with terrible oxygenation, the Berlin Definition offers no room for stratifying and identifyng true ARDS patients since there is no further re-evaluation of the hypoxemia under standard ventilator setting in a specific time period.

Long live the King! The original phrase was translated from the French Le Roi est mort, vive le Roi! Xdra first, let us review briefly the dsra history of the definition of ARDS.

The Kigali modification of the berlin definition: a new epidemiological tool for ARDS?

friterios They studied a cohort of patients who were receiving respiratory support, and from this cohort they identified 12 patients with a syndrome that was similar to the Infant Respiratory Distress Syndrome. The respiratory distress was defined as sudden, catastrophic, and often associated with a multiorgan system insult which led to tachypnea, hypoxemia, decreased respiratory system compliance, and bilateral pulmonary infiltrates on chest X-ray due to non-cardiogenic pulmonary edema.

Since that time, the hallmark of this syndrome has included: ARDS is caused by an inflammatory insult to the alveolar-capillary membrane that results in increased permeability and subsequent interstitial and alveolar edema. Since it is difficult to measure changes in capillary and alveolar permeability criterips the bedside, diagnosis of ARDS is based on a combination of clinical, oxygenation, hemodynamic and radiographic criteria.

These criteria allow the inclusion of a heterogeneous group of critically ill patients since various types of injury can lead to a similar pulmonary response. The original description of ARDS was incapable of identifying a uniform group of patients.

Several patients from the original cohort would not be classified as ARDS today, since fluid overload was an important etiological factor. Thus, a precise definition is important for accurate identification and quantification of various aspects of the underlying pathophysiology and to select the best therapeutic approach in selected subgroups of patients.

Given that severe hypoxemia is the hallmark of ARDS, hypoxemia is crucial to the assessment of the severity of ARDS, for predicting the evolution in any given patient, and for assessing the response to treatment. Although this definition formalized the criteria for the diagnosis of ARDS and is simple to apply in the clinical setting, it has been challenged over the years in several studies.

Also, the physiological thresholds of the AECC definition do not require standardized ventilatory support. InVillar et al.

The major implication of these findings is that the use of the AECC ARDS definition to enroll patients into clinical trials may result in the inclusion of patients with highly variable severity of lung injury and mortalities. If the subjects in a trial have a very low risk of the condition that the intervention is hypothesized to prevent, the trial — regardless of criteriow size — will not verify the value of the intervention.

Consequently, it can be argued that the ARDSnet trial failed to focus on the highest risk patients. Because many patients without sustained ARDS may have been enrolled, it is conceivable that a disproportionate number of patients meeting ALI or ARF criteria ended up in the control arm, negating the beneficial effect of the treatment because of the lower mortality of these patients.

This is contrary to published data from Villar et al. This resulted in a homogeneous group of patients in whom the benefit or lack of benefit of a therapy could be appropriately evaluated. Most of the patients Berlni other patients had a marked improvement of their pulmonary dysfunction within the first 24 h. In a recent epidemiological study, Villar et al. A proposal for an update of the AECC ARDS definition has been published recently 6 by a task force panel of experts using a similar terminology as we had previously reported.

Using teleconferencing, in-person discussions and retrospective data, they proposed an ARDS classification with three severity categories mild, moderate, and severe paa empirical evaluation.

The panel used 7 datasets: Although the authors stated that the purpose of their empirical definition was not to develop a prognostic tool, this exercise should be cautiously generalized for the following methodological reasons.

We did not include those patients in our studies because in many centers they are usually not treated with endotracheal intubation and invasive MV. It has been postulated that the development of ARDS should have decreased because of advances in supportive care, particularly the application of protective mechanical ventilation.

In conclusion, we need more specific guidelines based on a standard method of evaluating oxygenation status i. As we have reported in the several studies discussed in this review, a large variability in the severity of lung damage exists in patients meeting sdrz AECC ebrlin of ARDS and a strong correlation exists between oxygenation impairment at 24 h after ARDS onset and ICU outcome. However, no matter how infrequently we observe its presence we need to be able to properly classify its severity.

The authors have no conflict of interest to declare.
