Case Reports[Assessment of the permeability of the pulmonary microvasculature using radiotracers in a case of adult respiratory distress syndrome].
A 48-year-old man with small cell lung cancer developed ARDS, and massive pulmonary edema fluid was obtained with the fiberoptic bronchoscopy. The pulmonary edema fluid to serum ratios of total protein and albumin were 0.72 and 0.85 respectively. The ratio of LDH was higher (2.71), while that of cholesterol was lower (0.11) than that of total protein. ⋯ The time activity curves of I-123 IMP and I-131 HSA in his blood samples revealed almost constant radioactivity from 5 minutes to 120 minutes after injection, while both radioactivity levels in pulmonary edema fluid samples increased with time. The clearance ratio of I-123 IMP to I-131 HSA was constant at each sampling time (mean +/- SD, 1.51 +/- 0.32). The linear correlation between I-123 IMP clearance and I-131 HSA clearance (r = 0.95, p less than 0.01) suggested that the clearance ratio of exudative plasma components may remain unchanged even if pulmonary microvasculature permeability has changed.

[Hemopurification in the management of ARDS complicating multiple organ failure].
In the field of critical care medicine, it has been claimed that ARDS often develops as a part of multiple organ failure (MOF). Since multi-modality therapy is necessary in the management of MOF, it is also mandatory even in the management of ARDS. ⋯ However, our recent experiences suggest that continuous hemofiltration (CHF) and/or continuous hemodiafiltration (CHDF) are safest, most easily performed and effective hemopurification in the management of ARDS/MOF. The efficacy of hemopurification in the management of ARDS is summarized as follows. 1) Removal of humoral mediators and causative substances of ARDS following insults such as sepsis and trauma. 2) Treatment of pulmonary interstitial permeability edema which has been claimed to be one of the most important pathological conditions in ARDS. 3) Removal of excess water given as carrier in IVH solution and accumulating in the body. 4) Immunomodulation which has also been considered to be necessary in the treatment or prevention of ARDS.

Between February 1988 and March 1990, ECMO was performed (veno-arterial perfusion; 3 cases, venovenous; one case) is 4 ARDS patients. However no patient could be weaned from ECMO (32-80 hours) and all died. The causes of deaths were attributed to the complications of ARDS itself that existed before ECMO therapy and ECMO was highly effective in providing temporally life support. We consider that entry criteria of ECMO should not be based on gas exchange alone and that lung compliance and circulatory insufficiency should be taken into account.

Comparative StudyThe cost of an intensive care unit: a prospective study.
The cost of intensive care for patients admitted to the ICU were estimated. Patients suffering from severe combined acute respiratory and renal failure who required mechanical ventilation and renal replacement therapy (SCARRF-D) cost per day significantly more than non-renal patients (pounds 938 compared to pounds 653 per patient respectively) and their average length of stay in hospital is nearly 4 times as long (28.8 compared to 7.6 days respectively). Approximately 44% of the total cost was staff related (28% for the provision of nurses and 16% for the rest). Retrieving information related to cost was difficult, time consuming and labour intensive.
