Over the past several decades, advances have been made in the treatment of ARDS; however, meta-analyses during this time period have shown conflicting results regarding mortality rates. The purpose of this study was to assess the mortality rate of ARDS between 1996 and 2011 in a large patient sample.\u003C\/p\u003E\u003Cp id=\u0022p-9\u0022\u003EThe NIS represents a stratified sample of 20% of US community hospitals. Patients included those with ICD-9 codes for pulmonary insufficiency secondary to surgery or trauma or to an unknown cause, ARDS, and ventilator support. Patients were excluded if they had ventilator support of unknown duration. Although causes of mortality were not part of this study, results showed that the mortality rate of patients with ARDS dramatically declined, from \u0026gt; 45% in 1996 to \u0026lt; 35% in 2011.\u003C\/p\u003E\u003Cp id=\u0022p-10\u0022\u003EOther studies have suggested that improved hygiene, restrictive transfusion protocols, prophylactic measures, sepsis identification and treatment, glucose control, and nutritional support may be important factors [Erickson SE et al. \u003Cem\u003ECrit Care Med.\u003C\/em\u003E 2009; Zambon M, Vincent J-L. \u003Cem\u003EChest\u003C\/em\u003E. 2008]. Although ARDS mortality was decreasing prior to 2000, a sudden and sharp decline was observed from 2000 to 2005, which may be attributed to the publication in 2000 of a study showing the benefit of low tidal volume ventilation [ARDS Network. \u003Cem\u003EN Engl J Med.\u003C\/em\u003E 2000].\u003C\/p\u003E\u003Cp id=\u0022p-11\u0022\u003ENirmal S. Sharma, MD, University of Alabama at Birmingham, Birmingham, Alabama, USA, presented data from a survey of perspectives of critical-care physicians on the role of extra-corporal membrane oxygenation (ECMO) in the management of refractory ARDS. There is a wide variation in how intensivists manage patients with severe or refractory ARDS and a lack of definitive guidelines for severe\/refractory ARDS if conventional mechanical ventilation fails to achieve a response. The purpose of this survey was to determine the current practices of intensivists when managing patients with severe\/refractory ARDS.\u003C\/p\u003E\u003Cp id=\u0022p-12\u0022\u003EThe majority of survey respondents (72%) manage patients with severe ARDS at least 3 to 4 times per month. If conventional mechanical ventilation did not achieve a response, respondents used strategies such as ECMO (68%), inhaled nitric oxide or prostacyclin (65%), airway pressure release ventilation (APRV; 64%), prone positioning (45%), and high-frequency oscillatory ventilation (29%).\u003C\/p\u003E\u003Cp id=\u0022p-13\u0022\u003EIn addition, fellows were more likely to use ECMO, whereas pulmonary and critical-care specialists preferred inhaled nitric oxide. ECMO was available at 80% of the represented institutions; where ECMO was not available, 43% of respondents never and 42% rarely transferred patients to the nearest facility with ECMO.\u003C\/p\u003E\u003Cp id=\u0022p-14\u0022\u003EThere were several barriers associated with use of ECMO. A majority of respondents (87%) indicated that ECMO technology was not available in most institutions, and 83% felt that there was not enough experience or training for use of ECMO among critical-care physicians. In addition, only 30% of respondents indicated that ECMO should be favored over other modalities for the treatment of refractory ARDS. Surprisingly, almost half of respondents thought that ECMO was associated with high costs and poor outcomes among patients with refractory ARDS.\u003C\/p\u003E\u003Cp id=\u0022p-15\u0022\u003EShehabaldin Alqalyoobi, MD, University of Missouri Kansas City School of Medicine, Kansas City, Missouri, USA, presented data from a study that evaluated the use of an angiotensin II receptor blocker (ARB) in a rat model with fat embolism (FE).\u003C\/p\u003E\u003Cp id=\u0022p-16\u0022\u003EAlthough the mortality rates of ARDS have sharply declined, it is still quite high despite recent advances.
