NEW COMPOSITE HEMOSTATIC SYSTEM MEMBRANE IN LIVER SURGERY

Abstract

Achieving a hemostatic effect by physical methods of influencing the wound surface and bleeding vessels of the parenchyma is rational, mainly with its shallow and superficial injuries. To stop bleeding from parenchymal vessels with a diameter of more than 1.0 mm, an increase in the exposure and power of energy exposure is required, which inevitably leads to damage to the stromal elements of the organ and increases the area of parenchymal necrosis to a depth of 4-8 mm, and the resulting coagulation scab often serves as a substrate for infection and recurrent bleeding. Physical methods of hemostasis during operations on parenchymal organs do not meet the requirements of the "ideal method", which should be accompanied by minimal or no blood loss, minimal necrosis of the parenchyma and a reduction in the operation time. In this regard, the development of fast-acting, safe, efficient and economical hemostatic materials is of great clinical and social importance.
