From the Guidelines
Vinegar (acetic acid) solutions are not recommended as a routine measure for preventing encrustation and infection in patients with indwelling catheters, as evidence from a randomized double-blind study showed no effect on levels of CA-bacteriuria from twice-daily bladder irrigation with acetic acid versus sterile saline 1.
Key Points to Consider
- The use of acetic acid as a bladder irrigant has been studied, but the evidence does not support its routine use for preventing catheter-associated urinary tract infections (CA-UTIs) or encrustation in patients with indwelling catheters.
- A study involving 89 community-residing persons with neurogenic bladders and indwelling catheters found that twice-daily bladder irrigation with acetic acid had no effect on levels of CA-bacteriuria compared to sterile saline 1.
- The prevention of CA-UTIs and encrustation in patients with indwelling catheters should focus on other evidence-based measures, such as maintaining a closed drainage system, ensuring proper catheter insertion and care, and using antimicrobial prophylaxis when necessary.
- Catheter blockage due to encrustation can be a significant issue, and strategies to prevent this should be based on the best available evidence, which currently does not support the routine use of acetic acid irrigation.
Clinical Implications
- Clinicians should be cautious when considering the use of acetic acid solutions for bladder irrigation in patients with indwelling catheters, as the evidence does not support its effectiveness in preventing CA-UTIs or encrustation.
- The focus should be on implementing evidence-based practices that have been shown to reduce the risk of CA-UTIs and other complications associated with indwelling catheters.
- Further research may be needed to identify effective strategies for preventing encrustation and CA-UTIs in patients with indwelling catheters, but currently, acetic acid irrigation is not recommended as a routine measure 1.
From the Research
Role of Vinegar in Preventing Encrustation and Infection
- Vinegar, or acetic acid, has been studied as a potential solution for preventing encrustation and infection in patients with indwelling catheters 2.
- A study from 1978 found that irrigation with 0.25% acetic acid had no effect on the urinary bacterial count in patients with indwelling catheters and pre-existing urinary tract infections 2.
- However, it is worth noting that other solutions, such as 0.02% chlorhexidine and 0.25% silver nitrate, were found to be effective in reducing bacterial counts 2.
Preventing Catheter-Associated Urinary Tract Infections (CAUTIs)
- CAUTIs are a common complication associated with the use of indwelling urinary catheters 3, 4, 5.
- Studies have shown that proper technique, aseptic site preparation, and limiting the use and duration of catheter placement can help prevent CAUTIs 3, 4, 5.
- Alternative devices, such as female external urinary collection devices, have also been shown to reduce the risk of CAUTIs in female patients 6.
Managing Complications Associated with Indwelling Catheters
- Encrustation is a common complication associated with the use of indwelling urinary catheters 4.
- While vinegar has been studied as a potential solution for preventing encrustation, other methods, such as regular irrigation and proper catheter maintenance, may be more effective 4.
- Nurses and healthcare professionals play a crucial role in preventing and managing complications associated with indwelling catheters, including CAUTIs and encrustation 3, 4, 5.
