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.

Prognostic value of acute physiology and chronic health evaluation II and organ system failure in patients with acute renal failure requiring dialysis.
Despite advances in modern technology of dialysis, prognosis of patients with acute renal failure (ARF) remains poor. To give the clinicians the most useful information, a model that accurately predicts outcome early in the course of ARF is required. However, because ARF is a heterogeneous syndrome and occurs in patients with diverse etiologies and some coexisting diseases, predicting outcome early is hard. The aim of this study is to evaluate prospectively the Acute Physiology and Chronic Health Evaluation (APACHE II) and organ system failure (OSF) models, evaluated prior to dialysis, in predicting hospital mortality. ⋯ This study concludes that APACHE II and OSF number measured prior to initiation of dialysis reliably predict outcomes of ARF patients requiring dialysis. The mortality rates increase as the APACHE II score or OSF number increases. For predicting mortality, the APACHE II score > or = 24 was found to have 63% sensitivity and 96% specificity, and OSF number> or = 2 had 81.6% sensitivity and 60.9% specificity.

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.
