Masclans et al followed 38 patients with ARDS in 3 ICUs for 6 months. Health-related quality of life (Nottingham Test Profile) was lower than expected at 6 months, with 40% reporting limitations in daily activities mainly due to low energy, mobility and social functioning. Mild radiographic abnormalities and restrictive physiology were usually present on HRCT [… read more]

Prone positioning improves oxygenation in ARDS patients without improving outcome. Recruitment maneuvers do too. Rival et al prospectively tested the effects of both strategies together in 16 ARDS patients. Two extended sighs of 45 cm H2O in pressure control mode while lying prone improved PaO2/FiO2 from 98 to 166 mm Hg, without obvious adverse (or positive) effects. Critical [… read more]

Databases suggest that 60-70% of patients with severe respiratory failure due to H1N1 received steroids. Brun-Buisson et al looked back at a French registry including 208 patients with H1N1 and ARDS, 83 of whom received steroids. They found a hazard ratio of 2.4 for death associated with steroid administration, rising to 2.8 after applying their propensity scoring [… read more]

Those patients with severe acute lung injury due to pneumonia or aspiration who received the rSP-C surfactant product did no better on important outcomes (28-day survival, need for ventilation, organ-failure-free days) than those receiving usual care, report Spragg et al.(n=843). AJRCCM 2011;183:1055-1061.

Meade MO et al. (Lung open ventilation study investigators) Ventilation strategy using low tidal volumes, recruitment maneuvers, and high positive end-expiratory pressure for acute lung injury and acute respiratory distress syndrome: a randomized controlled trial.  JAMA 2008; 299:637-45. Higher PEEP provided no benefit in 28-day mortality (28 vs 32%, p = 0.2), although it reduced refractory hypoxia (~5% [… read more]

Brower RG et al. Higher versus lower positive end-expiratory pressures in patients with the acute respiratory distress syndrome. N Engl J Med 2004;351:327-36.  Randomized trial among 549 patients with ARDS/ALI conducted by NHLBI/ARDSNet. Compared high and low PEEP strategies, and found no significant difference in mortality, ventilator-free days, ICU-free days, or organ failure-free days between [… read more]

Herridge MS et al. One-year outcomes in survivors of the acute respiratory distress syndrome. N Engl J Med. 2003; 348:683-93. Non-pulmonary problems are usually dominant in impairment of ARDS survivors. Low exercise tolerance, fatigue, and weakness are common a year after discharge. Pulmonary function tests usually normalized, other than a diffusion impairment. At 12 months, only 6% [… read more]

ARDS Network. Ventilation with lower tidal volumes as compared with traditional tidal volumes for ALI and ARDS. N Engl J Med 2000;342:1301-8. The ARMA study found the use of low (6 ml/kg predicted weight) rather than “standard” (12 ml/kg predicted weight) tidal volumes reduced mortality from 40 to 30%. This paper established the standard of low [… read more]
