Poor agreement in the calculation of venoarterial PCO2 to arteriovenous O2 content difference ratio using central and mixed venous blood samples in septic patients.
Central venous minus arterial PCO2 to arterial minus central venous O2 content difference ratio (Pcv-aCO2/Ca-cvO2) has been proposed as a clinical surrogate for respiratory quotient. Our goal was to assess its interchangeability with mixed venous minus arterial PCO2 to arterial minus mixed venous O2 content difference ratio (Pmv-aCO2/Ca-mvO2). ⋯ In this study, Pcv-aCO2/Ca-cvO2 and Pmv-aCO2/Ca-mvO2 were not interchangeable. In addition, Pmv-aCO2/Ca-mvO2 is a composite variable, which depends on several determinants. Values of Pcv-aCO2/Ca-cvO2 should be cautiously interpreted in the assessment of critically ill patients.

Histologically proven acute tubular necrosis in a series of 27 ICU patients.
Since renal biopsy is rarely performed for identifying acute tubular necrosis in ICU patients, there is little information on the real histopathological abnormalities observed in such situations. ⋯ Septic and non-septic ICU patients with ATN had similar histopathologic features but lesions were more severe than in septic than in non-septic patients.

Organ donation education in the ICU setting: a qualitative and quantitative analysis of family preferences.
Determine family-centered methods of providing organ donation education to families in ICU waiting rooms. ⋯ ICU families desire accurate information about organ donation, and are receptive to its provision in the acute ICU setting. Family-centered approaches to information delivery may enhance understanding of organ donation processes and aid decision-making about organ donation.
