From the Research
To flush a suprapubic catheter, sterile normal saline (0.9% sodium chloride) is the recommended solution. This recommendation is based on the principle of using an isotonic solution that won't irritate the bladder lining, reducing the risk of infection and other complications. The provided evidence does not directly address the specifics of flushing suprapubic catheters, but general medical knowledge and principles of infection control support the use of sterile normal saline for this purpose 1, 2, 3, 4.
When flushing a suprapubic catheter, it's essential to follow proper technique to minimize the risk of introducing bacteria into the bladder. This includes:
- Washing your hands thoroughly before starting the procedure
- Wearing clean gloves
- Using a sterile syringe with a capacity of at least 50 ml
- Disconnecting the catheter from the drainage bag
- Attaching the syringe filled with saline to the catheter
- Gently instilling the solution
- Allowing the fluid to drain back into the syringe or into a collection container
The volume of saline used for flushing can vary, but typically, 30-50 ml is recommended for each flush. Flushing should be performed when there are signs of blockage, such as decreased urine output or cloudy urine, and usually not more than once daily unless directed by a healthcare provider. The importance of aseptic technique cannot be overstated, as it is crucial for preventing infections and ensuring the longevity and effectiveness of the suprapubic catheter 2.
While the provided studies focus on various aspects of suprapubic catheterization, including the risks and benefits, insertion procedures, and long-term management, they do not specifically address the flushing of these catheters. However, the principles of using sterile equipment and maintaining asepsis are consistent across all aspects of catheter care, supporting the recommendation for using sterile normal saline for flushing suprapubic catheters.
