In short
This article explores the use of Ethanol (96 Per Cent) in clinical trials aimed at optimizing skin preparation for shoulder surgery in male patients. The focus is on reducing Cutibacterium acnes colonization, a common cause of infection in shoulder arthroplasty. The study compares different skin preparation methods, including the use of alcoholic iodine povidone solution containing Ethanol (96 Per Cent), to improve surgical outcomes and reduce infection rates.

What is ETHANOL (96 PER CENT)?
ETHANOL (96 PER CENT) is a form of highly concentrated alcohol. It's also known by several other names, including: Alcohol (96%) Ethanol 96% Ethyl alcohol 96% Ethanol 96% (V/V) This substance is commonly used in medical settings for its antiseptic properties, meaning it can kill or slow the growth of microorganisms on the skin.
Medical Use in Shoulder Surgery
In the context of shoulder surgery, ETHANOL (96 PER CENT) is being studied as part of a skin preparation solution. It's combined with another substance called povidone-iodine to create an antiseptic solution. This combination is used to clean the skin before surgery to reduce the risk of infection.
Clinical Trial: OPRICA Study
A clinical trial called OPRICA (Optimization of skin preparation to reduce Cutibacterium acnes colonization in superficial and deep samples during prosthetic shoulder surgery in male patients) is currently studying the use of this ethanol-based solution. The main goals of this study are: To evaluate how effective a 5% alcoholic iodine povidone solution is at reducing bacteria on the skin before shoulder surgery. To compare this method with another approach using a different substance called benzoyl peroxide. The study focuses on a specific type of bacteria called Cutibacterium acnes, which is commonly found on human skin and can cause infections after shoulder surgery.
Application and Dosage
In the OPRICA study, the ethanol-based solution (BETADINE ALCOOLIQUE 5%) is applied to the skin just before surgery. It's used as a single-dose cutaneous solution, which means it's applied directly to the skin in the area where the surgery will be performed.
Patient Eligibility
The study is specifically looking at male patients who are having shoulder surgery. Some key eligibility criteria include: Patients without a history of previous shoulder surgery on the operated shoulder Patients undergoing specific types of shoulder joint replacement surgeries Patients who are covered by social security Patients who have given informed consent to participate in the study There are also several conditions that would make a patient ineligible for the study, such as having certain skin conditions, ongoing infections, or allergies to the substances used.
Potential Benefits
The main potential benefit of using this ethanol-based solution is reducing the risk of infection after shoulder surgery. The study aims to determine: How effective the solution is at reducing bacteria on the skin Whether it can help prevent infections for up to 2 years after surgery How it compares to other methods of skin preparation
Precautions and Side Effects
While the study is still ongoing and full results are not yet available, there are some general precautions to be aware of: The solution is for external use only and should not be ingested Patients with known allergies or sensitivities to iodine or alcohol should inform their healthcare provider The study is monitoring for any skin irritation or other adverse reactions to the solution
