ARDS is a complex response of the lung to direct (inhalational) and indirect (hematogenous) insults. It is easy to be pessimistic about the benefit of the approaches we have described, but there is evidence that overall survival has improved in recent years. To maintain this progress, new therapies for ARDS must be rigorously evaluated, and their routine(More)
We performed a randomized, prospective trial to evaluate whether fluid management that emphasized diuresis and fluid restriction in patients with pulmonary edema could affect the development or resolution of extravascular lung water (EVLW), as well as time on mechanical ventilation and time in the intensive care unit (ICU), in critically ill patients(More)
One hundred seventy-four patients (179 admissions) were prospectively evaluated for the subsequent occurrence of upper gastrointestinal ("stress") bleeding after admission to a medical/respiratory intensive care unit. Evidence for either overt or occult gastrointestinal bleeding developed in 25 (14 percent). The group of bleeders had a higher mortality (64(More)
Succinylcholine, a short-acting neuromuscular blocking agent, was used to accurately measure the pulmonary artery occlusion pressure (PAOP) in eight patients requiring mechanical ventilation for acute respiratory failure, in whom measurement was difficult because of significant respiratory variation in PAOP. The mean decrease in PAOP after paralysis was 9.8(More)
Although pulmonary artery (PA) catheterization is frequently employed in the management of critically ill patients, there is little documentation that the information obtained alters patient management. This study evaluated prospectively this question in 103 PA catheterizations. Before catheterization, physicians were asked to predict the range of several(More)
The medical records of 77 patients with hematologic malignancy who were admitted to a medical intensive care unit over a 21-month period were reviewed. The overall hospital mortality rate was 80 percent. Sixteen patients (21 percent) were discharged from the intensive care unit but eventually died in the hospital. The cause of death was the result of a new(More)
Eicosanoid production appears to be important to both edemagenesis and the pattern of pulmonary perfusion in experimental acute lung injury (ALI). We hypothesized that these effects could be mediated by the inducible form of cyclooxygenase (COX-2). We used positron emission tomography to evaluate the pulmonary perfusion pattern in dogs given oleic acid (OA)(More)
UNLABELLED PET with 18F-FDG may be useful for quantifying neutrophilic activation. We previously demonstrated that pulmonary neutrophil sequestration could be detected during acute lung injury (ALI), even without migration into the alveolar compartment. Using the influx constant Ki as the method to quantify lung 18F-FDG uptake, we also showed that Ki(More)
