Guidelines for Preventing Infection in the Catheterized Patient:
- Use scrupulous aseptic technique during insertion of the catheter. Use a preassembled, sterile, closed urinary drainage system.
- To prevent contamination of the closed system, never disconnect
the tubing. The drainage bag must never touch the floor. The bag
and collecting tubing are changed if contamination occurs, if
urine flow becomes obstructed, or if tubing junctions start to leak
at the connections.
- If the collection bag must be raised above the level of
patient’s bladder, clamp the drainage tube. This prevents backflow of contaminated urine into the patient’s bladder from
- Ensure a free flow of urine to prevent infection.
drainage occurs when the tubing is kinked or twisted, allowing
pools of urine to collect in the tubing loops.
- To reduce the risk of bacterial proliferation, empty
bag at least every 8 hours through the drainage spout—more
frequently if there is a large volume of urine.
- Avoid contamination of the drainage spout. A receptacle
to empty the bag is provided for each patient.
- Never irrigate the catheter routinely. If the patient
is prone to
obstruction from clots or large amounts of sediment, use a threeway system with continuous irrigation.
- Never disconnect the tubing to obtain urine samples, to
the catheter, or to ambulate or transport the patient.
- Never leave the catheter in place longer than is necessary.
- Avoid routine catheter changes. The catheter is changed
correct problems such as leakage, blockage, or encrustations.
- Avoid unnecessary handling or manipulation of the
the patient or staff.
- Carry out hand hygiene before and after handling the
tubing, or drainage bag.
- Wash the perineal area with soap and water at least
twice a day;
avoid a to-and-fro motion of the catheter. Dry the area well, but
avoid applying powder because it may irritate the perineum.
- Monitor the patient’s voiding when the catheter is
patient must void within 8 hours; if unable to void, the patient
may require catheterization with a straight catheter.
- Obtain a urine specimen for culture at the first sign of infection.
