A Historical Review of Barrier Materials

Abstract

When surgical gowns first were used, their primary purpose was to protect patients from members of the surgical team. In 1952, it was revealed that although the muslin the garments were made from may have been an effective barrier when dry, it lost barrier capability after it became wet. This disclosure triggered research to develop more satisfactory materials for this unique application. In the interim, the emergence of HIV was accompanied by the need to protect surgical team members from patients, and barrier effectiveness attained even greater importance. During the past 50 years, several attempts have been made to develop a universally acceptable and meaningful test method to demonstrate a material's barrier capability under conditions that simulate usual conditions of use. None has been successful. Today, with the trend toward minimally invasive surgery and pressure to reduce costs, perioperative nurses are confronted with selecting a product that is appropriate for the task and degree of exposure anticipated.

Surgeon's garb and infection control: What's the evidence?

“…In 1952 Beck and Collette 96 published an article entitled ''False faith in the surgeon's gown and surgical drape,'' which described the shortcomings of J AM ACAD DERMATOL VOLUME 64, NUMBER 5 Eisen 960.e10 surgery garments constructed out of 140 thread count cotton. 97 An explosion of research into the development of new gowns and different types of garment materials occurred as a result. [97][98][99] Most gowns were constructed of very high thread count cotton, disposable paper products referred to as ''nonwoven'' material, synthetic substances, or various combinations of the previously mentioned materials.…”

“…Schwartz and Saunders 101 as well as Different test methods have been advocated by the various gown manufacturers and physicians to assess their performance as suitable barriers. 97 In the hope of coming to a consensus on a suitable testing technique, Beck et al 103 assembled an interdisciplinary committee to develop a standardized testing methodology. 98 The group disbanded in 1983 because of lack of consensus.…”

“…The American Society for Testing Materials, an industry group, proposed a testing technique using a complex mechanical device. 97 Studies performed both in vivo and in vitro have found that garments that passed this standard still resulted in strike through. 104,105 Thus, an acceptable standard for operative garments appears to be lacking.…”
