In healthcare settings, preventing infections at IV and venipuncture sites is paramount. Proper disinfection plays a vital role in reducing the risk of complications. This article explores the research conducted over the last 3 years to determine the most effective solution for IV and venipuncture site cleaning, comparing chlorhexidine, alcohol, betadine and povidone iodine-alcohol.

1. 2% chlorhexidine and 70% alcohol swabs

Recent research supports the use of 2% chlorhexidine and 70% alcohol swabs for IV and venipuncture site cleaning. A study published in the American Journal of Infection Control in 2021 concluded that this combination exhibited superior antimicrobial efficacy compared to other solutions, reducing the risk of catheter-related bloodstream infections (CRBSI) significantly [1]. The combination鈥檚 broad-spectrum action, targeting both bacteria and fungi, makes it a promising choice.

2. Chlorhexidine

Chlorhexidine alone has also been extensively studied. A systematic review published in JAMA Surgery in 2019 analyzed multiple trials and found that chlorhexidine alone was effective in preventing CRBSIs [2]. Its use has gained popularity due to its strong antimicrobial properties and lower risk of allergic reactions compared to iodine-based solutions.

3. Alcohol

Alcohol alone has been a traditional choice for site cleaning. A 2020 study in the Journal of Hospital Infection evaluated the effectiveness of alcohol-based skin disinfection for central venous catheter insertion and concluded that it remains a suitable option [3]. However, it may not offer the same level of broad-spectrum coverage as chlorhexidine.

4. Betadine (iodine solution)

Betadine, an iodine-based solution, has been utilized for IV site cleaning. A study published in the American Journal of Critical Care in 2020 found that betadine was effective in reducing CRBSIs [4]. However, concerns exist regarding iodine allergies and the potential for skin staining.

5. Povidone iodine-alcohol

The combination of povidone iodine and alcohol has been explored as well. Research published in Critical Care Medicine in 2018 indicated that this combination exhibited strong antimicrobial properties, particularly against multidrug-resistant organisms [5]. However, it may not be the preferred choice for patients with iodine allergies.

Superior antimicrobial properties

Selecting the best solution for IV and venipuncture site cleaning involves considering various factors, including the patient鈥檚 allergies, the specific procedure and antimicrobial efficacy. Recent research supports the use of 2% chlorhexidine and 70% alcohol swabs as a promising choice, demonstrating superior antimicrobial properties in preventing CRBSIs [1]. Chlorhexidine alone also remains a strong contender [2], while alcohol, betadine and povidone iodine-alcohol may be considered depending on individual patient characteristics and preferences [3-5].

Healthcare providers should stay informed about the latest research findings and tailor their disinfection practices to ensure the best outcomes for patient care and safety.
