Applicateur Arista™ AH FlexiTip™ XL, 38 cm, 5 par caisse

•  Topical hemostats include agents that act as a mechanical barrier to bleeding and provide a physical matrix for clotting, biologically active agents that catalyze coagulation, and combination therapies. ²
• Hemostats can enhance clot formation and wound healing, and can be useful for controlling or preventing troublesome bleeding during surgical interventions where conventional methods of hemostasis are inadequate.²

• The acronym “RAPID” can be used to remember the application steps:
  
• R (Remove): Remove all access blood
• A (Apply): Apply AristaTM AH liberally to the bleeding site
• P (Pressure): Administer wound-appropriate pressure until hemostasis is achieved
• I (Irrigate): Irrigate and remove excess Arista™  AH from the site
• D (Done): Hemostasis Hemostasis achieved— quickly, safely and effectively

• With the FlexiTip™ spray applicator, applying Arista™ AH accurately and directly is fast and simple. The delivery system features a lightweight, plastic device with a long, flexible tube. The FlexiTip™  and FlexiTip™ XL extended reach applicator tips provide the precise and accurate delivery of Arista™ AH hemostatic powder from a simple, single-use device.¹
•  Arista Application: see instructions for use ¹  

• Directions for Use:

1.  Blot, wipe, or suction the bleeding tissue. It is important to remove excess blood so Arista™ AH may be applied immediately and directly to the site of active bleeding.
2. Position the applicator tip as close to the source of bleeding as possible. Immediately apply a liberal amount of Arista™ AH at the site of bleeding within the wound, to completely cover the wound. Deep wounds may require equally deep application of Arista™ AH. To minimize occlusion of the tip, pressure should be applied to deliver Arista™ AH as the applicator enters the wound
3. Quickly apply wound-appropriate, direct pressure over the treated site. Use of a non-adhering substrate to apply pressure may prevent adhesion of  the  formed  clot to the surgical glove or other instrumentation. Amount and duration of pressure is wound dependent. For oozing, pressure may not be necessary. For more profusely bleeding wounds, pressure should be maintained longer.
4. If bleeding or oozing continues, remove excess Arista™ AH and reapply.
5.  If any material other than the clot-bound Arista™  AH  (i.e.  surgical dressing) adheres to the wound site, irrigate the material with saline and carefully remove it from the treated site.
6.  Immediately upon contact with blood or fluid, Arista™ AH will swell to approximately 5 times its original volume. Once hemostasis is achieved, excess Arista™ AH should be carefully removed by irrigation and aspiration. Avoid irrigation of direct suction of the formed blood clot.¹

• Administration: A liberal amount of Arista™ AH should be applied to the bleeding site (see DIRECTIONS FOR USE) followed by pressure until hemostasis  is  achieved.  After hemostasis is achieved, Arista™  AH  should  be  removed  by  irrigation  and/or  aspiration.¹

• A wide variety of topical hemostats are approved as adjunctive therapies in the maintenance of hemostasis during surgical procedures in which conventional methods are insufficient or not practical.²
•  Potential cost benefits in terms of preventing the further utilization of hospital resources to manage surgical bleeding. In addition to other patient blood management strategies, the intraoperative use of topical hemostats may reduce the need for transfusion of blood products (e.g., packed red blood cells, platelets, fresh frozen plasma) and reduce the duration of postoperative care (length of hospital stay) each of which is associated with substantial costs.²
