Abstract:
We sought to test whether Celox topical hemostatic dressing (Medtrade Products) would maintain hemostasis in extended use.An anesthetized swine underwent bilateral arteriotomies and treatment with topical hemostatic dressings in line with the Kheirabadi method. The dressings were covered with standard field dressings, and these were visually inspected for bleeding every 2 hours until 8 hours, when the swine was euthanized.There was no evidence of rebleeding at any point up to and including 8 hours. The Celox dressings maintained hemostasis in extended use.Celox topical hemostatic dressing is effective for extended use and maintains hemostasis. It should be considered for use in situations in which evacuation and definitive care may be delayed.Keywords:

The aim of this paper is to study the hemostasis and security of soluble hemostatic gauze in the rabbit liver hemorrhage model.After making the rabbit liver hemorrhage model, the control group used sterile gauze to stop bleeding, the positive control group used TISTAT to stop bleeding, the test group used soluble hemostatic gauze to stop bleeding. Hemostasis, blood loss and animal clinical symptoms were measured. Liver and kidney parameters, along with histopathology were recorded and analyzed. Transmission electron microscopy examination was also done.The blood loss is cut back and hemostasis is shortened in the test group. Other tests have no difference with the control group.No toxic effects on rabbit are found in the test group. The hemostatic effects have no difference with positive control group.

Flowable gelatin matrix products have established themselves as effective, easy-to-use hemostatic agents useful in a variety of surgical situations. A recently reformulated gelatin matrix, Surgiflo® (Ethicon Inc., Somerville, NJ), can be prepared quickly and provides consistent flow over an 8-hr. period. No in vivo studies have yet been reported comparing hemostasis with the new Surgiflo to other currently marketed flowable gelatin matrix products. This study was conducted to determine whether Surgiflo in actual use has hemostatic qualities different from another commercial gelatin matrix. An in vivo model based on porcine spleen biopsy punch-induced bleeding was used to compare Surgiflo and Floseal™ (Baxter Healthcare Corporation, Hayward, CA), both with thrombin. Time required to achieve hemostasis and proportion of sites achieving hemostasis within 30 s were determined for both hemostatic agents and a control of saline-soaked gauze. Results were stratified by the degree of initial bleeding (mild, moderate, severe). Hemostasis was achieved within 3 minutes at all sites for both test products regardless of level of initial bleeding, and control sites continued bleeding past 10 minutes. There were no statistically significant differences between Surgiflo and Floseal for either mean time to hemostasis or proportion of sites hemostatic within 30 s. In this realistic in vivo model both gelatin matrix products were effective, and there were no significant differences observed in hemostatic efficacy between Surgiflo and Floseal. Other factors, such as ease of preparation and application, in-use stability, and economic considerations may affect a surgeon's decision in selection of a desirable hemostatic product.

To investigate the hemostasis of thermosensitive chitosan hemostatic film.Fifty adult Sprague Dawley rats, male or female and weighing 190-210 g, were made the models of liver injury. The models were randomly divided into 5 groups (n=10) depending on different hemostatic materials. The incision of the liver was covered with the hemostatic materials of 2.0 cm x 1.0 cm x 0.5 cm in size: thermosensitive chitosan hemostatic film (group A), chitosan hemostatic film (group B), cellulose hemostatic cotton (group C), gelatin sponge (group D), and no treatment (group E), respectively. The bleeding time and bleeding amount were recorded. After 4 weeks, the incisions of the liver were observed with HE staining.Gross observation showed better hemostatic effect and faster hemostatic time in groups A, B, and C; group D had weaker hemostatic effect and slower hemostatic time; group E had no hemostatic effect. The bleeding time and bleeding amount of groups A, B, C, and D were significantly lower than those of group E (P < 0.05). The bleeding time and bleeding amount of groups A, B, and C were significantly lower than those of group D (P < 0.05), but no significant difference was found among groups A, B, and C (P > 0.05). The liver cells of group A had milder edema and ballooning degeneration than other 4 groups through histological observation.The thermosensitive chitosan hemostatic film has good hemostasis effect on the liver incision of rats.

Uncontrolled bleeding from trauma or surgery remains an important factor affecting the survival and prognosis of surgical patients. Failure to timeously stop bleeding will not only prolong the operative time but also threaten the patient’s life. Timely hemostasis after bleeding has become the most concerned event for surgeons. At present, the most commonly used hemostasis methods in the operating room include ligation of blood vessels, electrocautery, and gauze compression to stop bleeding. However, These hemostatic methods do great harm to surrounding tissues while achieving hemostasis. Based on tissue engineering repair strategies, the use of natural polymer materials as hemostatic agents has achieved clinical success. Gelatin sponge and cellulose gauze have been used clinically with good results. However, gelatin sponges are very expensive and place enormous financial pressure on patients. Therefore, there is an urgent need for new hemostatic materials for surgical hemostasis. Chitosan is a natural polysaccharide with biocompatibility and biodegradability, which plays an important role in tissue engineering and regenerative medicine. Chitosan gauze has been proven to have good hemostatic effects. The positive charge on the surface of chitosan can adsorb red blood cells and platelets at the bleeding site to form platelet thrombosis. However, chitosan is not easily soluble in water and has poor adsorption, which makes it a weak local hemostatic agent. Therefore, it is important to improve chitosan-based hemostatic material such that it l has an excellent hemostatic effect. In this review, we introduce the physiological coagulation process and discuss the physicochemical properties of chitosan and its role in hemostasis. Furthermore, we discuss the advantages and disadvantages of chitosan-based hemostatic materials. Finally, we summarize and discuss chitosan-based hemostatic materials.

The treatment of bleeding wound of solid visceral and the rescue of uncontrollable bleeding are still confronted with difficulties in surgery and first-aid field. Many researchers devote to study in the field of hemostasis, and the novel porous hemostatic agent is one of the hot spot of research about hemostasis. The review focuses on the hemostatic effect, properties, hemostatic mechanism, shortcoming and future trends of three novel porous hemostatic agents such as polysaccharides, zeolite and wollastonite.

Continuous bleeding after using conventional hemostatic methods involving energy, sutures, or clips, is a serious and costly surgical complication. Many topical agents have been developed to promote intraoperative hemostasis, but improvement is needed in both decreasing time to hemostasis and increasing ease of use. Veriset™ hemostatic patch is CE-marked for controlling bleeding on the liver and in soft tissue. In the current study, we aimed to gather further evidence for the safety and effectiveness of Veriset™ hemostatic patch in soft tissue bleeding during a variety of surgical procedures.Thirty patients scheduled for nonemergency surgery, each with an intraoperative soft tissue bleeding site, were treated with Veriset™ hemostatic patch. Time to hemostasis was monitored, and adverse events were assessed during the 90 days after surgery.When Veriset™ hemostatic patch was used, hemostasis occurred within 5 minutes in 29/30 (96.7%) subjects and within 1 minute in 21/30 (70.0%) subjects. No device-related serious adverse events were recorded during the 30 days after surgery, and no reoperations for device-related bleeding complications were performed during the 5 days after surgery.Veriset™ hemostatic patch is a safe and effective hemostat for controlling soft tissue bleeding during a variety of surgical procedures.
