Randomized Controlled Trial Clinical Trial
Torsemide versus furosemide after continuous renal replacement therapy due to acute renal failure in cardiac surgery patients.
Diuretic therapy in ARF (acute renal failure) is mainly done with loop diuretics, first of all furosemide. Torsemide has a longer duration of action and does not accumulate in renal failure. In chronic and acute renal failure, both diuretics have been effectively applied, with a more pronounced diuretic effect for torsemide. ⋯ In conclusion, torsemide and furosemide were effective in increasing urine output. Torsemide might show a better dose-dependent diuretic effect in ARF patients after CRRT treatment. Serum creatinine and blood urea nitrogen elimination were less pronounced in the furosemide group.

Randomized Controlled Trial Clinical Trial
Effect of off-pump and on-pump coronary artery bypass grafting on renal function.
Coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) has the risk of renal dysfunction. The cause of renal dysfunction after CPB is multifactorial, such as nonpulsatile flow, renal hypoperfusion, hypothermia, and duration of CPB. This study compared off-pump technique with on-pump technique on renal function in patients who underwent CABG. ⋯ The off-pump technique may provide a positive contribution and sufficient protection on postoperative renal functions in patients undergoing CABG.

Randomized Controlled Trial Comparative Study
A prospective randomized study to compare ultrasound-guided with nonultrasound-guided double lumen internal jugular catheter insertion as a temporary hemodialysis access.
Internal jugular venous catheters (IJVC) for hemodialysis are a commonly employed temporary vascular access for hemodialysis. Most hospitals still follow the use of blind technique, which uses anatomical landmarks. Even in the most experienced hands this procedure has a variable success rate. Ultrasound guidance can decrease the incidence of periprocedural complications and improve the success rate. In this randomized study we compared the procedure success rate and periprocedural complications in patients undergoing ultrasound guided vs. nonultrasound guided IJVC insertion for a temporary hemodialysis access. ⋯ Ultrasound guided procedure for internal jugular vein catheter insertion using an ordinary ultrasound machine was significantly safer and more successful as compared to the blind technique.

Comparative Study
Mortality risk factors and validation of severity scoring systems in critically ill patients with acute renal failure.
Risk stratification and prediction of outcome in acute renal failure patients in the intensive care unit are important determinants for improvement of patient care and design of clinical trials. ⋯ Cross-validation of prognostic models for ARF resulted in poor performance of all studied scores. Therefore, a specific model is still warranted for the design of clinical trials, comparison of studies, and for prediction of outcome in ARF patients, especially in the ICU.

Acute renal failure (ARF) is common and difficult to prevent, especially in intensive care unit (ICU) patients with cancer. Therapeutic trials with various agents have generally been ineffective in preventing ARF. We describe the effects of two different doses of the dopamine DA-1 receptor agonist fenoldopam mesylate on renal function in a series of critically ill cancer patients at risk of developing ARF. ⋯ These data support the hypothesis that fenoldopam mesylate may provide a degree of dose-dependent renal protection in cancer patients with early acute renal failure.
