We examined a sodium alginate preparation (Alto) to determine its hemostatic effect, in comparison with other topical drugs, on hemorrhages in the uterocervical area. A total of 149 patients with hemorrhage from cervical erosion or after-treatment bleeding of the cervix uteri were subjects in this trial, and 84 (79%) of 106 patients treated with this preparation experienced a hemostatic effect. A significant positive correlation (p < 0.001) was noted between the degree of tissue adhesiveness and the hemostatic effect in all the drugs tested. As for the tissue adhesiveness, Alto was significantly more favorable (p < 0.001) than both Thrombin and Francetin T powder. Because Alto was softened by tissue moisture, its topical adhesiveness could be increased, which suggested that Alto was superior in hemostasis.
