Find out how single-use operating theatre clothing and drapes prevent germ transfer and how they compare to reusable materials.
Reducing the risk of wound infections with disposable surgical clothing
Different operations have different risks of infection. Long, complex operations involving high levels of blood and irrigating fluids, carry the highest risk while risk is lower, but still present, in shorter operations where large amounts of body fluids are not expected.
Even with careful observance of hygiene standards, and execution of the usual antibiotic prophylaxis, there is infection at the surgical site in approx. 1-5 % of elective surgical procedures. For the patients affected, this means an extension of their pain and functional restrictions – even if there are no more serious consequences.
Patient care and health economics
Minimising infection is primarily about patient care, but it is also a fundamental consideration in hospitals’ health economics. A study of the University Hospital of Wisconsin, USA, shows that the additional period of hospitalisation that is required for treating postoperative infections in surgery represents a decisive cost factor.
Single use vs. Reusable Materials
The material used in drapes and sterile clothing also raises issues of health economics. Draping materials and operating theatre clothing made of nonwoven fabric are often preferred to reusable textile systems due to the material safety and the associated high level of protection against infection. Although these are the most important reasons, another benefit is that single-use materials remove the need for sophisticated reprocessing of reusable textile systems, which is a cost-intensive undertaking.
Medical products are classified in two performance levels: high performance and standard performance. This means that draping materials and operating theatre clothing can be tailored exactly to the respective surgery-specific requirements in material quality and product design. This flexibility allows hospitals to choose safe, cost-effective standard performance drapes for low risk operations and specific tailored surgical gowns for higher risk operations involving large amounts of body fluids.
Single-use and reusable products are subject to the same safety standards as applied to reusable products for their entire life cycle. Their production and quality testing are subject to European Standard EN 13795. The most important test methods relate to the material properties that are essential for reliable protection against infection: particle release (linting) (ISO 9073-10), resistance to liquid penetration (European Standard EN 20811) and wet microbial penetration (European Standard EN ISO 22610).
