CUTTING EDGE-SCIENCE
2022 Shawnee, USA October Results: Damage to the spleen in rats with mixed bleeding is simulated by inflicting a wound with a scalpel, while a linear wound is applied along the outer surface of the spleen to the capsule of the inner edge of the spleen for a length of up to 2 cm. The spleen in rats varies depending on the age and weight of the animals. The average size of the spleen of a rat weighing 250-300 g in length is up to 3 cm, therefore, with a cut length of up to 2 cm, a subtotal dissection of the parenchyma is achieved. In this case, active mixed bleeding is achieved, which does not tend to stop on its own. The intensity of bleeding was assessed by applying dry gauze balls and napkins until the bleeding stopped completely on its own. As a result of the study, it was found that the created model causes bleeding of a mixed type, which lasts for 5-10 minutes with a loss of up to 1.5-2 ml of blood, which is more than 30% of the BCC. After achieving hemostasis, the abdominal cavity is sutured tightly. After the operation, the animals woke up for quite a long time. Animal activity is sluggish. On the next day, it was found that out of 4 operated individuals, death occurred in 2. When opening the abdominal cavity, the presence of liquid blood with clots was noted, the color of the internal organs was anemic. The removal of two other rats from the experiment made it possible to establish the presence of up to 1 ml of liquid blood in the abdominal cavity, as well as a large hematoma in the area of the spleen wound. Thus, the proposed method is novel and is characterized by the achievement of active bleeding from the spleen in an experimental animal, which does not tend to stop on its own and without hemostasis, repeated blood loss leads to death. Advantages of the new method: the ability to achieve active bleeding, which does not tend to stop on its own and without hemostasis, repetitive blood loss leads to death; the method is easily reproducible and does not require a special tool; the method allows evaluating the effectiveness of local hemostatics both in terms of the effectiveness of primary hemostasis and the likelihood of rebleeding.
