Comparative Study Clinical Trial
A novel method for regional citrate anticoagulation in continuous venovenous hemofiltration (CVVHF).
Continuous renal replacement therapy (CRRT) is increasingly used in managing acute renal failure (ARF) as it offers hemodynamic stability and significant solute clearance in this setting. However, it also requires anticoagulation. Traditionally, heparin has been the anticoagulant of choice but this increases hemorrhagic risk in already high-risk ARF patients. Regional citrate anticoagulation offsets this risk. However, it can be difficult to manipulate regional anticoagulation in CRRT. Moreover, citrate CRRT has been plagued by short optimal filter patency times. ⋯ This novel CVVHF-citrate system achieved excellent clearance and dramatically improved filter patency compared to saline-flush systems. Moreover, it did so with minimal toxicity.

Acute renal failure is the most common complication of rhabdomyolysis, with an 8-20% reported incidence. In particular, rhabdomyolysis associated with acute renal failure is frequently observed in critically ill patients, with a 6-16% reported incidence in Intensive Care Units. Dialytic treatment is necessary to correct hydroelectrolytic imbalance and renal function alterations and it may be a pathogenetic therapy by myoglobin removal. ⋯ Early dialytic treatment of RML allows not only to avoid life-threatening complications (first of all the acute renal failure) but moreover it's a pathogenetic treatment because it removes great amount of myoglobin from the plasma. Beside this, continuous renal replacement therapy allows a successful management of critically ill patients with severe hemodynamic conditions. Nevertheless, the final outcome may be very different between ICU- and NICU-patients, with a higher mortality rate in ICU-patients, suffering from MODS.

To evaluate the organ system failures hospital mortality predictions in critically ill patients with acute renal failure requiring dialysis. ⋯ We conclude that mortality rate for acute renal failure in intensive care unit patients continues to be high. Organ system failures prediction model performed well and simple in its ability to identify patients who die in hospital. Mortality rate increases as number of failed organ increases.

Despite the widespread availability of dialytic and intensive care unit technology, the probability of early mortality in critically ill patients with acute renal failure (ARF) is still high, and the evaluation of the patients' prognosis has been difficult. The Acute Physiology and Chronic Health Evaluation II (APACHE II) score is a reliable indicator of severity of illness and likelihood of survival in critically ill patients with ARF. We have attempted to determine whether the APACHE II scoring system can be used to predict prognosis. ⋯ We conclude that mortality rate for acute renal failure in intensive care unit patients continues to be high. The use of the APACHE II score determined at the time of initiation of dialysis for patients with ARF is a statistically significant predictor of patient survival. There is a significant trend with APACHE II score for outcome.
