Cyanoacrylate spray in the treatment of prolonged oral bleeding.

n-Butyl-cyanoacrylate is an effective hemostatic agent. Optimal efficiency depends on local application via a spray to achieve a thin and elastic film. Construction of a spray applicable to the oral cavity is illustrated using a plastic ampule with Histoarkryl as reservoir. This spray has been used in 27 cases of prolonged bleeding to achieve hemostasis. In 18 cases the patients suffered from different hemorrhagic diatheses and general hemostatic procedures would normally have been necessary to achieve hemostasis. In nine patients without hemorrhagic diathesis, the cyanoacrylate spraying replaced more complicated local procedures. In 24 cases the cyanoacrylate spraying was a sufficient hemostatic treatment.
