RESUMO
OBJECTIVE: Major vascular injury is one of the most important causes of death after trauma. The effective and speedy control of the hemorrhage is crucial in reducing deaths. Many products are used for this purpose. Today, however, an ideal product has not yet been produced and there is a strong demand for such effective hemostatic products. The aim of this study is to compare the efficacy of Algan hemostatic agent with Floseal in the liver laceration model in rats. MATERIALS AND METHODS: A total of 28 rats were used in the study. Rats were divided into 4 groups, each consisting of 7 rats. Experimental liver laceration was established. In the control group, saline-impregnated gauze was applied. Algan hemostatic agent-impregnated sponge, Algan hemostatic agent powder, and Floseal gel were applied to the experimental groups. RESULTS: There was no difference in bleeding control among the Algan hemostatic agent powder, Algan hemostatic agent-impregnated sponge, and Floseal. When compared to the control group, Algan hemostatic agent powder, Algan hemostatic agent-impregnated sponge, and Floseal were found to be very effective in bleeding control, respectively (P=.001, .012, and .002), in the experimental groups. CONCLUSION: This study showed that the properties of both Algan hemostatic agent powder and Algan hemostatic agent-impregnated sponge for controlling bleeding are similar to Floseal. Considering other characteristics such as Algan hemostatic agent's naturalness, easy applicability, and low cost, Algan hemostatic agent has been a promising effective hemostatic agent.
RESUMO
BACKGROUND: Algan Hemostatic Agent (AHA) is a multi-herbal extract containing a standardized amount of Achillea millefolium, Juglans regia, Lycopodium clavatum, Rubus caesius or Rubis fruciosus, Viscum album, and Vitis vinifera, each of which is effective in hemostasis. In this study, we aimed to investigate the effects of AHA on bleeding time in a rat tail hemorrhage model. METHODS: Forty-eight Sprague Dawley rats (5-7 weeks old, 180-210 g) were randomly and equally allocated to six groups as follows: heparin plus saline (heparinized control), heparin plus AHA-soaked sponge, heparin plus liquid form of AHA, saline (non-heparinized control), AHA-soaked sponge and liquid form of AHA. Heparin (640 IU/kg) was administered intraperitoneally three times a day for three days in heparinized groups. For the bleeding model, the tail of rats was transected. According to the study group, either saline- or AHA-soaked sponge or liquid form of AHA was applied over the hemorrhage area. In AHA- or saline-soaked sponge groups, once the bleeding time had started, it was checked every 10 seconds. If the bleeding did not stop after 40 seconds, it was accepted as a failure. In liquid AHA group, the duration of bleeding was measured using a chronometer and defined as the time (seconds) from wounding until the bleeding stopped. RESULTS: Bleeding time in the heparinized and non-heparinized control groups was over 40 seconds. After applying the sponge form of AHA on the wound area, bleeding time was significantly shortened to less than 20 seconds in both heparinized and non-heparinized rats (p<0.001 for both). The liquid form of AHA stopped bleeding in 5.0±1.2 seconds and 8.0±1.3 seconds in heparinized and non-heparinized groups, respectively. CONCLUSION: AHA is a highly effective topical hemostatic agent in a rat tail hemorrhage model, thus may provide for a unique clinically effective option for control of bleeding during surgical operations or other emergencies.
