Bacterial strike-through of re-usable surgical drapes: the effect of different wetting agents
Abstract:
Wound contamination and the resultant postoperative infection is a major problem in all forms of surgery. Air contamination, gloves, surgical instruments and drapes have all been investigated as sources of wound contamination. We investigated the effect of different wetting agents on strike-through rate of bacteria through re-usable polyester/cotton surgical drapes using a newly described method. Within 30 min bacterial strike-through of dry surgical drapes occurs. Wetting drapes with blood or normal saline enhances the strike-through rate of bacteria. Wetting drapes with iodine or chlorhexidine diminishes, but does not stop, bacterial strike-through. The use of re-usable polyester/cotton drapes is a potential source of wound contamination especially when wetted with blood or normal saline.
Insights
Reusable surgical drapes can transfer bacteria, leading to wound contamination and infection. Wetting these drapes with blood or saline significantly increases bacterial strike-through, posing a surgical risk.
Area of Science:
- Surgical Infection Prevention
- Microbiology
- Textile Science
Background:
- Postoperative wound contamination and infection remain significant surgical challenges.
- Potential sources of bacterial contamination include air, gloves, instruments, and surgical drapes.
- Reusable textiles are commonly used in surgical settings.
Purpose of the Study:
- To evaluate the impact of various wetting agents on bacterial penetration through reusable polyester/cotton surgical drapes.
- To assess the risk of wound contamination from surgical drapes under different conditions.
Main Methods:
- A novel method was employed to quantify bacterial strike-through.
- Reusable polyester/cotton surgical drapes were tested.
- Drapes were wetted with different agents including blood, normal saline, iodine, and chlorhexidine.
Main Results:
- Bacterial strike-through was observed through dry surgical drapes within 30 minutes.
- Wetting drapes with blood or normal saline markedly increased bacterial strike-through rates.
- Iodine and chlorhexidine reduced, but did not eliminate, bacterial strike-through.
Conclusions:
- Reusable polyester/cotton surgical drapes can act as a conduit for bacterial contamination.
- The risk is amplified when drapes are contaminated with blood or saline.
- Antimicrobial wetting agents offer partial protection but do not fully prevent bacterial penetration.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...
Surface Membrane Barriers
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
