What is ChloraPrep preoperative skin preparation?
What is ChloraPrep preoperative skin preparation?
ChloraPrep preoperative skin preparation is a rapid-acting and persistent preoperative skin preparation. Its proven formulation is available in six unique applicators designed for procedures ranging from peripheral IV insertion to major surgery.
What are the active ingredients of ChloraPrep preoperative skin preparation?
The active ingredients in ChloraPrep preoperative skin preparation are chlorhexidine gluconate (CHG) 2% w/v and isopropyl alcohol (IPA) 70% v/v.
Is ChloraPrep preoperative skin preparation FDA approved?
Yes. After submitting a New Drug Application (NDA) to the Food & Drug Administration, ChloraPrep preoperative skin preparation received FDA approval in 2000.
How is receiving FDA approval for an NDA different than meeting the requirements of the FDA Tentative Final Monograph for Topical Antimicrobial Drug Products for Over-the-Counter Human Use?
When seeking FDA approval for an over-the-counter antiseptic, all manufacturers of chlorhexidine-based solutions are required to submit a New Drug Application (NDA). The review of a NDA by FDA includes evaluation of clinical, manufacturing and labeling information to assure the product is safe and effective. Alcohol and iodophors were identified by FDA as "Generally Recognized As Safe and Effective" (GRASE) and are included in the Tentative Final Monograph from the FDA. As a result, manufacturers of alcohol, iodophors and iodine-based solutions can market products without submitting efficacy and safety data and product labeling to the FDA for review prior to marketing and selling their products.
Which CDC guidelines recommend the use of a 2% chlorhexidine solution for skin antisepsis?
ChloraPrep preoperative skin preparation meets the CDC's Guidelines for the Prevention of Intravascular Catheter-related Infections, published in 2002. The guidelines state that "clean skin with a >0.5% chlorhexidine preparation with alcohol before central venous catheter and peripheral arterial catheter."
What category of CDC recommendation does 2% CHG receive?
The use of a 2% chlorhexidine-based preparation for cutaneous antisepsis is classified as a Category 1A recommendation—the highest level of recommendation the CDC bestows. A Category 1A recommendation is clean skin with a >0.5% chlorhexidine preparation with alcohol before central venous catheter and peripheral arterial catheter."
Tell me about the ChloraPrep tints. Why are some applicators tinted, and are they safe?
The tint process for ChloraPrep Scrub Teal and Hi-Lite Orange® tints is a patented technology that adds color to the solution as it enters the sponge pad. When applied to the skin, each tint allows for easy visualization of the prepped area. Unlike iodine-based preps, which are brown, Scrub Teal and Hi-Lite Orange tints are easy to see when applied to a variety of skin tones. The dyes in Scrub Teal and Hi-Lite Orange are Food, Drug and Cosmetic (FD&C) Green #3 and Yellow #6 dyes, and have been ""Generally Recognized As Safe"" (GRAS) by the Food and Drug Administration (FDA). For an ingredient to be listed as GRAS, extensive safety testing is conducted, reviewed and accepted. FD&C Green #3 is a common colorant used in many applications throughout the healthcare field (e.g., eye angiography and screening for ocular dryness, routine lab testing, dye injections, histological/cytological stains for cancer screening of tissues). FD&C Green #3 and Yellow #6 were found to be stable when combined with the 2% chlorhexidine gluconate/70% isopropyl alcohol ChloraPrep formulation, which offers proven, stable and uncompromised chlorhexidine-based solutions.
In addition to CDC guidelines, are there other evidence-based guidelines that recommend the use of preoperative skin preparations containing chlorhexidine?
Yes. Chlorhexidine gluconate is highly recommended by at least 18 organizations and initiatives, with 11 specifically advocating a 2% formulation. For a complete listing click here.
Scientific and clinical support of 2% CHG and 70% IPA
Why is the combination of 2% chlorhexidine gluconate (CHG) and 70% isopropyl alcohol (IPA) better than IPA alone?
The combination of fast-acting and long-lasting antimicrobial activity is the key to an effective preoperative skin preparation. IPA alone provides a 99.99% reduction in bacteria, but it does not provide long-lasting microbial kill. CHG maintains antimicrobial activity, demonstrating 2 log10 and 3 log10 for at least 48 hours1,2 compared to two hours for free iodine.3 Because ChloraPrep preoperative skin preparation contains the combination of isopropyl alcohol and chlorhexidine, it is more effective than isopropyl alcohol alone.
How does ChloraPrep preoperative skin preparation compare to traditional iodophors?
Advantages of ChloraPrep preoperative skin preparation include its broad spectrum, rapid-acting and persistent antimicrobial activity(48 hours) and effectiveness in the presence of blood and organic matter. These advantages are a result of the unique 2% CHG/70% IPA formulation of ChloraPrep preoperative skin preparation. Chlorhexidine gluconate, a cationic bisbiguanide, works by destroying the bacterial cell membrane and precipitating cell contents. Alcohol denatures cell proteins. As a result, ChloraPrep preoperative skin preparation provides better broad spectrum, immediate, cumulative and residual antibacterial activity compared to traditional iodophors. In contrast, traditional iodophors can take two to three minutes until the free release of iodine can occur. While the iodophor dries, free iodine becomes available. The iodine then attacks the bacterial cell and the oxidation of two sulfhydryl groups, resulting in the formation of a disulfide bond. The effectiveness of iodophors is ≤ three hours. Lastly, iodophors are neutralized in the presence of blood and organic matter and have greater irritation than the CHG solution.4
Does clinical data support the use of chlorhexidine to help reduce the incidence of infection?
Yes. Chlorhexidine-based antiseptics have been used globally for more than 50 years and have been widely used in Europe, Canada and Japan for more than 30 years. In the United States alone, more than 100 studies (excluding those focused on hygiene data) have been published, revealing positive outcomes related to the use of CHG-based antiseptics. Studies that used ChloraPrep preoperative skin preparation specifically, represent close to 25% of the published CHG data in the healthcare setting.
Can ChloraPrep preoperative skin preparation help reduce the risk of blood culture contamination?
Yes. A prospective blood culture study showed CHG was highly effective in reducing the contamination rate of blood cultures. The rate of blood culture contamination was lowered to 0.5% (1 of 215 cultures) with CHG.5 Another blood culture study found that tincture of iodine yielded a slightly higher contamination rate than chlorhexidine. In addition, iodine tincture has the disadvantage of being toxic when used repeatedly, while toxicity was found to be very uncommon with chlorhexidine.6
Can you explain the science of ChloraPrep preoperative skin preparation?
The chlorhexidine bisbiguanide groupings associate strongly to exposed anionic sites on the cell wall and cell membrane, particularly acidic phospholipids and proteins, causing displacement of divalent cations (Ca2+ and Mg2+). Bridging adjacent phospholipids in the cell membrane will cause a loss of structural integrity, reduce membrane fluidity and allow leakage of cellular materials.7Bacterial cells are negatively charged, but in the presence of chlorhexidine, the bacterial cell is neutralized and the charge is reversed. The attraction of the cationic chlorhexidine molecule and the negatively-charged bacterial cell contributes to a rapid rate of bacterial kill; surface charge reversal is secondary to cell death.4
