可吸收止血材料的研究现状与应用.

BACKGROUND: Compared with traditional hemostatic methods, absorbable hemostatic materials are more expensive and have lower awareness, but they have greater advantages in certain surgical procedures. OBJECTIVE: To review the classification, clinical use, safety and development status of absorbable hemostatic materials. METHODS: The computer was used to search the PubMed database for relevant literature published from January 2003 to March 2020. The search terms were “Absorbable Hemostatic Agents; Fibrin adhesives; Hemorrhage; Hemostatic dressings; Hemostats; Mechanical hemostats; Sealants”. China National Knowledge Infrastructure was retrieved for relevant literature published from January 2004 to March 2020. The search terms were “absorbable hemostatic material; hemostatic material; clinical research”. RESULTS AND CONCLUSION: Absorbable hemostatic materials mainly produce hemostasis by accelerating the blood coagulation process of wounds. Common hemostatic products include cellulose, starch and other plant polysaccharides, gelatin/collagen, chitosan, and fibrinogen. Different materials have different hemostatic mechanisms. Oxidized regenerated cellulose, starch, gelatin/collagen and chitosan hemostatic materials mainly form platelets by providing platelet activation and aggregation. Fibrinogen hemostatic materials can be used in the coagulation cascade involved in the formation of fibrin clots. The use of absorbable hemostatic materials depends on the doctor’s experience or preference. Clinicians need to choose one or more hemostatic material combinations according to the actual situation of the patient. [ABSTRACT FROM AUTHOR]
