The clinical criteria of acute respiratory distress syndrome (ARDS) defined by the American-European Consensus Conference (AECC) in 1994 was relevant to clinical practice, trials, and researches for two decades. However, a number of issues with the AECC definition have become apparent. ⋯ In the second section, the clinical significance and limitation of radiographic imaging, especially, high-resolution CT (HRCT) findings in ARDS were addressed. Although the early exudative phase of ARDS can not be detected even by HRCT, pulmonary fibroproliferation assessed by HRCT in patients with early ARDS predicts increased mortality with an increased susceptibility to multiple organ failure, along with ventilator dependency and its associated outcomes.

Comparative Study
[Perioperative management of lung transplantations in patients with pulmonary arterial hypertension compared with that in patients with lymphangiomyomatosis].
The number of lung transplantation has tended to increase as a treatment for patients with pulmonary arterial hypertension (PAH) and lymphangiomyomatosis (LAM) in Japan. However, we have little evidence about the comparison of perioperative management in patients with PAH and that in patients with LAM. ⋯ The large difference in perioperative management between patients with PAH and those with LAM is an important knowledge for anesthesist.

The definition of acute respiratory distress syndrome (ARDS) by American-European Consensus Conference (AECC) in 1994 has promoted clinical and epidemiological research leading to improved survival outcome of the ARDS patients by establishing lung protective ventilation. On the other hand, no pharmacological therapy has yet proved to be effective despite substantial effort devoted to development and research. ⋯ Recently, a randomized trial and clinical experience in treating severe influenza have demonstrated favorable outcome of ECMO therapy in the management of severe ARDS. Future progress will depend on developing novel therapeutics that can ameliorate lung injury and systemic derangements and facilitate lung repair.

Acute respiratory distress syndrome (ARDS) is a noncardiogenic pulmonary edema resulting from increased capillary permeability. Numerous pharmacologic therapies have been studied for prevention and treatment of ARDS. Although several pharmacological therapies could improve patient's respiratory function, there have been no controlled studies which clearly demonstrated the clinical benefit for ARDS-related mortality. ⋯ With regard to sivelestat sodium, a specific inhibitor of neutrophil elastase, although the effectiveness in decreasing mortality was not clarified, increases in lung oxygenation and ventilator-free days have consistently been revealed. Other probable pharmacologic therapies for ARDS include continuous infusion of cisatracurium. In conclusion, there are not established drugs for ARDS, and further studies are necessary to reveal the clinical effectiveness of the above mentioned and novel pharmacologic therapies.

Randomized Controlled Trial
[Continuous infusion of low-dose remifentanil for palliation of pain with epidural catheterization].
To prospectively determine the safety and effectiveness of continuous infusion of low-dose remifentanil for the reduction of pain in patients for epidural catheterization. ⋯ Continuous infusion of low-dose remifentanil is a safe and effective method for palliation of pain in epidural catheterization.
