In-use evaluation of surgical gowns.
Surgical gowns must protect patients from the bacteria of operating room personnel and also protect staff members from the lethal viruses in the blood of patients. The current study was done to evaluate the barrier function of several surgical types of gowns during use in surgical procedures and identify the frequency of failure of the gowns and some causes for this failure. We performed direct observation of 234 operations during which the surgeon and the first assistant wore 535 gowns. Blood strikethrough occurred most often when contamination on the outside of the gown was heavy (20 per cent), but still occurred after medium (7 per cent) and small (1 per cent) contamination. We found significant differences between gowns based on the material used and the design of the gowns. Gowns reinforced with a second layer of material or a layer of plastic material were more effective at preventing strikethrough than a single layer of material. One gown was identified that was unacceptable for any use in the operating room. Gowns of different designs and degrees of protection should be chosen based on the body area likely to be exposed to blood and the amount of predicted blood contamination. Further improvement in gown materials and design are required, since surgeons cannot consider any of these gowns protective during strenuous use.
