Comparative evaluation of five surgical hand scrub preparations

Area of Science:

• Infection Control
• Microbiology
• Surgical Hygiene

Background:

• Surgical hand scrubs are critical for reducing microbial load on healthcare workers' hands and forearms.
• Maintaining low microbial counts during surgery is essential for preventing surgical site infections.

Purpose of the Study:

• To evaluate the immediate, persistent, and residual antimicrobial efficacy of five different surgical hand scrub formulations.
• To compare the effectiveness of chlorhexidine gluconate (CHG), iodophor, parachlorometaxylenol, and alcohol-based surgical hand scrubs.

Main Methods:

• Comparative efficacy study of five surgical hand scrub products.
• Assessment of immediate, persistent, and residual antimicrobial activity against microorganisms on hands and forearms.

Main Results:

• Two chlorhexidine gluconate (CHG) products showed significant immediate, persistent, and residual antimicrobial effects.
• An iodophor product demonstrated immediate and persistent efficacy but lacked significant residual effects.
• Parachlorometaxylenol and alcohol-based products exhibited minimal immediate, persistent, and residual antimicrobial activity.

Conclusions:

• Chlorhexidine gluconate (CHG) surgical hand scrubs are the most effective preparations for reducing and maintaining low microbial counts.
• CHG-based scrubs provide superior residual antimicrobial activity compared to iodophor, parachlorometaxylenol, and alcohol formulations.
