How often should an indwelling catheter be replaced?

Replacing an indwelling catheter every 72 hours is recommended as it helps to minimize the risk of infection and other complications associated with prolonged catheterization. Over time, the presence of a catheter in a patient's body can lead to biofilm formation and bacterial colonization, which increases the likelihood of urinary tract infections or other complications. By adhering to a 72-hour replacement schedule, it allows for regular assessment of the catheter's condition and patency, while also reducing the potential for catheter-associated complications. This timeframe strikes a balance between patient safety and the practical aspects of catheter management in veterinary practice. Regularly changing the catheter aids in maintaining optimal care and contributing to better patient outcomes.
