Title: Prolonged evaluation of epinephrine and normal saline solution injections in an acute ulcer model with a single bleeding artery
Abstract: Background: Animal studies of epinephrine or normal saline solution injection for bleeding ulcers do not consistently demonstrate local tamponade effect. Methods: We studied the change of bleeding rates of 28 acute gastric ulcers with a single bleeding artery in 10 dogs. Four injections of 1 mL epinephrine 1:10000 at 1 mm from the spurting artery (n = 7) were compared to four injections of normal saline solution 1 to 5 mL (n = 12) and to four dry needle sticks (n = 9). Bleeding rates were measured at initial arterial incision and at minutes 1, 5, 10, 15, 20, 25, and 30 after treatment. Result: Reductions in early blood loss to 24.3% ± .05 of baseline occurred with saline solution, to 17.7% ± .03 with epinephrine, and to 66.0% ± 1.8 in controls (p < .05 for epinephrine and saline solution vs control). A tendency for saline solution injected ulcers to resume bleeding was identified, with late blood loss increasing to 26.9% ± .05 of baseline, (saline solution vs control) compared to 7.7% ± .02 in epinephrine injected ulcers (p < .05 vs control). Conclusions: The early acute hemostatic effect of injection therapy depends on local tamponade. The prolonged hemostatic effect is a combination of tamponade and vasoconstriction, with advantage of epinephrine over saline solution. (Gastrointest Endosc 1995;42:51-5.)
