| Popis: | Cotton surgical patties are essential to control vessel bleeding. However, conventional cotton surgical patties tend to adhere to vessels through capillary action, especially when used in combination with hemostats. Consequently, after the bleeding is controlled, rebleeding often tends to occur after removal of the adhered cotton patty. Polyester film－coated non－woven fabric has replaced conventional gauze for the protection of burn wounds, because this material does not tend to adhere to the wound but retains the same capacity to absorb fluid discharges from the wound. We describe our manufacture of a new type of polyurethane－coated surgical patty, which was evaluated for its bleeding control when used in conjunction with a hemostat and for undesirable vessel adherence. Our newly developed surgical patty is made of 100％ cotton, with only the contact surface coated with polyurethane. The coated side contains many holes, so aspiration through the surgical patty is possible from both sides. For our evaluation, we used a surgical patty with or without polyurethane coating together with a gelatinous sponge for bleeding control in the sagittal sinus, with fibrin glue－soaked oxidized cellulose cotton for bleeding control in the cavernous sinus, and with a collagen sheet for bleeding control in brain capillary vessels, in 5 patients for each use. We found that the newly developed surgical patty could be removed from the hemostat and vessels without difficulty and rebleeding was not observed. The new polyurethane－coated surgical patties appear to be more effective for vessel bleeding control when used with several types of hemostats in different applications and at different locations as compared to conventional non－coated surgical patties. （Received December 26, 2013；accepted February 4, 2014） |
