of more than 100 to less than 120 mm Hg. Thus, it seems fair to call it normotensive. Nevertheless, in an older patient, a blood pressure under 120/80 mm Hg is often below its usual level and should be compared with previous readings. My concern with the definition of "acute kidney injury" is that it does not yet specify which causes of renal failure are included. For example, Zhou et al. do not include cases due to acute glomerulonephritis or systemic lupus erythematosus. 3 Although Bellomo et al. state that urinalysis lacks diagnostic value for renal failure due to sepsis, the report they cite 4 actually concluded that there were few data on this question and that good studies are needed. My experience is that urinalysis usually correlates well with the clinical picture. The finding of both high and low renal blood flows in studies of experimental septic acute renal failure 5 calls into question but does not rule out the role of ischemia in the pathogenesis of this condition.
Chan et al. (Wed,) studied this question.
