Tissue sealing.

Abstract

The tissue adhesive property of fibrinogen was first described 60 years ago. However, it was not until the availability of concentrated plasma fibrinogen and bovine thrombin that the use of fibrin sealants in surgical practice became widespread. Today, fibrin sealants are used for tissue sealing across a range of surgical procedures, including cardiothoracic, gastrointestinal, neurosurgery, and vascular surgery. Tissue sealing with fibrin sealant reduces perioperative hemorrhage and controls blood loss from cut surfaces of tissues that are difficult to suture. The use of fibrin sealants can also reduce perioperative and postoperative complications by reducing fluid leakage, air leakage, and by preventing fistulae formation. Fibrin sealants have a unique physiologic action, and the resulting fibrin clot is fully degraded by the body's natural wound healing process. The range of surgeries and types of procedure that incorporate the use of fibrin sealants in tissue sealing is expanding. As commercially prepared fibrin sealants become more widely available, the number of patients and surgeons benefiting from improved surgical outcomes is also set to increase. This article reviews the areas of surgery within which fibrin sealants are currently used to assist tissue sealing and highlights the improved surgical outcomes, such as reduced blood loss, operative time, and postoperative complications.

Fibrin sealants in clinical practice.

Fibrin sealants are used in a wide range of surgeries, primarily as hemostatic agents, but also to assist tissue sealing and wound healing. While all fibrin sealants contain fibrinogen and thrombin, they differ in their final composition. This affects the properties of the resulting fibrin clot and may influence their use in different surgical procedures. Sealants with high concentrations of fibrinogen tend to produce stronger clots, whereas those containing higher concentrations of thrombin form clots rapidly. This is essential when rapid hemostasis is required to stop blood loss (e.g. suturing of blood vessels). However, in situations that require careful adjustment of tissue (e.g. a skin flap) a slower clot formation is advantageous. Some sealants are supplemented with factor XIII and this may increase the tensile strength and stability of the clot and improve hemostasis. Antifibrinolytic agents (e.g. aprotinin and aminocaproic acid) increase the lifespan of the clot by inhibiting fibrinolysis. Fibrin sealants containing aprotinin may have an added advantage when used on surgical sites with naturally high concentrations of fibrinolytic agents. The physical properties of the fibrin sealants also vary. For example, the fibrinogen component is relatively viscous and requires a lot of force to inject it through a long catheter. Fibrin sealants with a fibrinogen component of low viscosity are easier to use than highly viscous solutions in surgical situations where the sealant is applied by a catheter. Until recently, the use of fibrin sealants in the USA has been limited to noncommercial products--'home-brews'. The fibrinogen concentration of these products can vary between preparations, with subsequent variation in the mechanical strength of the clot making handling difficult. The introduction of commercial sealants into the USA with consistent composition should reduce the varying performance of fibrin sealants, although autologous and point-of-use prepared sealants may still vary. Consistency of performance is expected to result in an increased use of fibrin sealants both in established and novel fields of surgery.
