Continuous arteriovenous hemofiltration: improved survival in surgical acute renal failure?

摘要: Continuous arteriovenous hemofiltration (CAVH) is an effective method for renal failure management that has the potential to decrease mortality rates. This hypothesis not been comparatively studied. Fifty six patients with acute oliguric complicating multiple organ had measurements of resting energy expenditure by indirect calorimetry, caloric and protein intake, balance, outcome. Two protocols included hemodialysis, full calories, low (phase I) or CAVH, high II). The survival rate in phase I was 12% 28% II (not a statistically significant difference); CAVH did facilitate parenteral feeding. Patients positive balance improved compared those deficit (37.5% versus 9.4%, p less than 0.025). We conclude nutritional support improves failure. replacement therapy secondary importance, but distinct advantages surgical patients.
