چکیده

BACKGROUND Renal replacement therapy (RRT) has been implemented extensively in people to facilitate recovery from acute renal failure (ARF). RRT has not been explored in horses, but might provide a further treatment option in horses with ARF. OBJECTIVE To investigate efficacy and safety of RRT in horses. ANIMALS Five healthy adult horses. METHODS A prospective study was performed on horses restrained in stocks and intravenously connected to a commercial RRT machine to allow continuous venovenous hemodiafiltration to be performed for 6 hours. The RRT machine was set at the following flow rates: blood flow rate 250 mL/min; dialysate rate 3,000 mL/h; prefilter replacement pump 3,000 mL/h; and postfilter replacement pump rate 2,000 mL/h. Balanced electrolyte solution was used as dialysate and replacement fluid. Heart rate, respiratory rate, body temperature, direct arterial blood pressure, urine output, and various clinicopathologic parameters were measured over the study period. RESULTS Renal replacement therapy was successfully performed in horses, resulting in a mean creatinine clearance of 0.127 mL/kg/min (68.9 mL/min) and urea reduction ratio of 24%. No adverse effects were detected although a significant decrease in rectal temperature was observed (P ≤ .007). A significant increase in serum phosphorus (P ≤ .001) and decrease in BUN (P < .001) were also noted. A significant prolongation of prothrombin (P < .01) and partial thromboplastin time (P < .0001) were observed along with a decrease in platelet count (P ≤ .04). CONCLUSIONS AND CLINICAL IMPORTANCE Renal replacement therapy can safely and effectively be used in adult horses.

Predictive value of plasma neutrophil gelatinase-associated lipocalin for acute renal failure in patients with severe sepsis.

BACKGROUND Predicting acute renal failure in patients with severe sepsis is important, because patients may need renal replacement therapy (RRT). Neutrophil gelatinase-associated lipocalin (NGAL) has been evaluated for its ability to detect and predict acute kidney injury (AKI) in critically ill patients. This study aimed to assess the predictive value of plasma NGAL for acute renal failure in ...

Antibiotic dosing in critically ill adult patients receiving continuous renal replacement therapy.

Continuous renal replacement therapy (CRRT) is now commonly used as a means of support for critically ill patients with renal failure. No recent comprehensive guidelines exist that provide antibiotic dosing recommendations for adult patients receiving CRRT. Doses used in intermittent hemodialysis cannot be directly applied to these patients, and antibiotic pharmacokinetics are different than th...
