How do I irrigate an indwelling catheter?

First, detach the drainage bag and tubing from the actual catheter. Attach a 60cc catheter-tipped syringe ("Toomey syringe") to the catheter and pull back to see if you can suction out sediment or clots. Next, fill the bladder slowly with 60cc of sterile water or normal saline via the syringe. Pull back on the syringe and all or most of the fluid should be drained. If the catheter does not irrigate properly, seek medical attention immediately.
