Quick Answer
Use a 4% chlorhexidine gluconate (CHG) surgical scrub for at least 2 minutes, covering all hand and forearm surfaces, then air dry before donning sterile gloves.
Why CHG is the Standard for Surgical Scrubbing
Chlorhexidine gluconate (CHG) is a broad-spectrum antimicrobial that provides rapid and persistent action against skin flora. Unlike plain soap, CHG binds to the skin, offering residual protection that lasts through the procedure.
The 4% concentration is specifically designed for healthcare personnel handwashing and surgical hand scrubbing, making it a reliable choice for the operating room.
Trade-Off: CHG vs. Other Antiseptics
While CHG is highly effective, it can cause irritation in some individuals, especially with repeated use. If you have sensitive skin or a known allergy, an alternative like povidone-iodine may be considered, but CHG remains the preferred choice for most surgical settings due to its persistent activity.
Step-by-Step CHG Surgical Scrub Procedure
- Prepare Your Hands and Workspace: Remove all jewelry, watches, and rings. Ensure fingernails are short and free of polish or artificial nails. Turn on the water and adjust to a comfortable warm temperature. Check that water flows freely and you have easy access to the CHG solution and a sterile towel.
- Wet Hands and Forearms: Wet your hands and forearms thoroughly under running water. Avoid splashing water onto your surgical attire. Keep hands elevated above elbows to allow water to flow from clean to less clean areas.
- Apply CHG Solution: Dispense the recommended amount of CHG surgical scrub (e.g., 5 mL) into your cupped hands. Avoid using a brush unless required by your facility policy. Ensure you have enough solution to cover all surfaces without running off.
- Scrub All Surfaces: Work the solution into a lather and scrub every surface of your hands, fingers, and forearms. Pay special attention to nail beds and between fingers. Continue for at least 2 minutes (or per your facility's protocol). Do not rush; use a timer or sing 'Happy Birthday' twice to gauge the time.
- Rinse Thoroughly: Rinse your hands and forearms under running water, keeping hands elevated. Move from fingertips to elbows, allowing water to run off without flowing back onto your hands. Ensure all lather is removed; residual CHG can cause skin irritation.
- Dry with Sterile Towel: Dry your hands and forearms with a sterile towel, using a patting motion. Start with your hands and work toward your elbows. Avoid rubbing, which can damage skin. Use a fresh section of the towel for each hand to avoid cross-contamination.
- Don Sterile Gloves: Once your hands are completely dry, put on sterile gloves using the closed-glove technique to maintain sterility. If you touch any non-sterile surface, restart the scrub process.
