Role of acetylcysteine in the prevention of contrast-media-induced nephrotoxicity.

The role of acetylcysteine in the prevention of contrast-media-induced nephrotoxicity was retrospectively studied. The medical records of patients undergoing cardiac catheterization between January 2000 and March 2002 were reviewed. The outcomes of patients with serum creatinine (SCr) concentrations above 1.

Alteplase versus urokinase in restoring blood flow in hemodialysis-catheter thrombosis.

The effectiveness of alteplase and urokinase in restoring adequate hemodialysis blood-flow rates was examined. A retrospective review of the medical records of hemodialysis patients with central venous catheters receiving alteplase or urokinase for presumed catheter thrombosis between June 1997 and December 2000 was conducted. Patients received 1 mL of alteplase 1 mg/mL or 1 mL of urokinase 5000 units/mL in each catheter port.
