CHG Applicators in Wound Care: Best Practices for Antiseptic Application


Wound care is a critical aspect of healthcare that requires diligent attention to prevent infection and promote healing. Antiseptic application is an essential step in wound care, as it helps eliminate or reduce bacteria on the skin surface. CHG (Chlorhexidine gluconate) applicators have gained popularity in recent years due to their effectiveness in preventing infection. This article will delve into the best practices for antiseptic application using CHG applicators, highlighting five key areas to ensure optimal wound healing.

1. Understanding CHG Applicators:

CHG applicators are pre-saturated with Chlorhexidine gluconate solution, a highly effective bactericidal agent. These applicators offer a convenient and controlled method for applying the antiseptic solution directly to the wound site. CHG is known for its broad-spectrum antimicrobial activity, including both gram-positive and gram-negative bacteria, making it an excellent choice for wound care.

2. Importance of Proper Hand Hygiene:

Before using CHG applicators, healthcare providers must prioritize hand hygiene. Thoroughly washing hands with soap and water for at least 20 seconds is crucial to eliminate any potential pathogens. Hand sanitizers with at least 60% alcohol can be used as an alternative when soap and water are not readily available. Ensuring clean hands minimizes the risk of introducing additional bacteria to the wound during antiseptic application.

3. Evaluating the Wound:

Every wound is unique and requires careful evaluation before applying any antiseptic solution. Assessing the wound's characteristics, such as its depth, size, presence of debris, and signs of infection, helps determine the appropriate treatment plan. Deep wounds or those with signs of infection may require additional medical attention beyond CHG applicator use.

4. Proper Technique for Antiseptic Application:

To maximize the effectiveness of CHG applicators, it is crucial to employ proper application techniques. The following steps outline the best practices for antiseptic application using CHG applicators:

a. Gently cleanse the wound: Remove any debris or excess exudate by gently irrigating the wound with a sterile saline solution. This step helps create an optimal environment for the antiseptic to work effectively.

b. Open the CHG applicator: Carefully remove the applicator from its packaging, being cautious not to touch the tip or contaminate it before application.

c. Apply the antiseptic: Begin by applying the solution to the wound bed, ensuring complete coverage. Gently swab the surrounding skin, extending approximately 2-3 cm beyond the wound edge. The generous coverage helps prevent bacteria migration and reduces the risk of infection.

d. Allow time for drying: CHG requires adequate drying time to exert its antimicrobial action. Depending on the wound type and depth, a drying time of at least 1-2 minutes is recommended before proceeding with dressing application.

5. Considerations for Dressing Selection:

After applying CHG using the applicator, selecting an appropriate wound dressing is an essential step. Factors like wound depth, exudate level, and presence of infection influence dressing choice. Dressings that offer a moist environment, facilitate gaseous exchange, and minimize pain during removal are often preferred. It is important to follow healthcare facility protocols and consult wound care specialists for dressing selection and change frequency guidance.


CHG applicators provide a convenient and effective method for antiseptic application in wound care. By following best practices such as proper hand hygiene, wound evaluation, and correct CHG applicator technique, healthcare providers can enhance patient outcomes by reducing the risk of wound infection. Remember to consider individual wound characteristics and adhere to facility protocols when selecting appropriate wound dressings. By staying up-to-date with the latest research and guidelines, healthcare professionals can continue to optimize the wound care process using CHG applicators.
