Answer

Answer

The urokinase dose for catheter clearance is 5000 U in each lumen over 1-2 minutes; this is left in the lumen for 1-4 hours and then aspirated. If 5000 U fails to clear the catheter, the process may be repeated with 10,000 U in each lumen. The volume to be instilled into the catheter is equal to the volume of the catheter. For patients undergoing dialysis, instill 5000 U into each lumen over 1-2 minutes, leave the agent in the lumen for 1-2 days, and then aspirate.
