Description

The invention relates to veterinary surgery and can be used in veterinary medicine for the delivery of local anesthetics to the organs of the pelvic cavity.

The known method of intrapelvic administration of novocaine in cows according to A.D. Nozdrachev [Shakurov, M.Sh. Novocaine blockade in veterinary medicine: textbook / M.Sh. Shakurov, S.V. Timofeev, I.G. Galimzyanov. - M .: KolosS, 2007. - 72 s]

The disadvantages of this method for small animals is the technical complexity of the injection access from the side of the croup.

The closest in technical essence to the proposed method is the method of intrapelvic novocaine blockade in small pets [Shocks. A.B. Intra-pelvic novocaine blockade in cats / A.B. Shock // Topical issues of veterinary medicine of small domestic animals: Proceedings of the interregional scientific and practical conference. - Novosibirsk, 2002. - S. 12.], including the insertion of an injection needle from the sciatic arch laterally in the direction from the beginning to one, and then to the other hip joints, while ensuring the blockade of the branches of the pelvic plexus.

For blockade, a 0.5% solution of novocaine 2.5 ml and a Luer needle 0.6x25 are used. The cat is fixed in a prone position, aggressive animals are injected with a minimum dose of tranquilizers. The needle is injected over the middle of the sciatic arch and injected subcutaneously with 0.5 ml of the solution, then the needle is advanced horizontally in the cranial direction along the entire length of the needle, pre-sending the solution to the movement of the needle (1 ml). After that, the needle is removed under the skin and injected laterally in the direction from the beginning to one, and then to the other hip joints to a depth of 10 mm, pre-sending the solution to the advancement of the needle (0.5 ml is injected).

The disadvantages of this method are high trauma, due to the complexity of the injection needle introduction, the risk of complications due to the ingress of solutions of injected fluids into the retroperitoneal space.

The technical result of the invention is to reduce trauma, reduce the likelihood of complications.

The technical result is achieved by the fact that the method of blocking the nerves of the accessory gonads in males of small animals, including the determination of the point of injection of the needle for injection of 0.5% solution of novocaine / injection of the needle, is carried out at the point of intersection of 2 lines on the ventral wall of the abdomen: the line of connection of the hip joints and the medial line of the abdomen, the reference point is the ventral pubic tubercle and the cranial edge of the pubic fusion, to a depth of 1.5-2 cm at an angle of 35-45 ° to the abdominal wall in the caudodorsal direction.

The point of injection of a needle for injection of 0.5% novocaine solution is carried out at the point of intersection of 2 lines on the ventral wall of the abdomen: the junction line of the hip joints and the medial line of the abdomen to a depth of 1.5-2 cm at an angle of 35-45 ° to the abdominal wall in the caudodorsal direction.

The specified point of injection of the needle provides a technically easier introduction of injection solutions into the pelvic cavity, which reduces the trauma of the method and provides quick and effective access directly to the nerve plexuses of the prostate and vesicular glands, excluding the injection of the solution into the retroperitoneal space, which reduces the likelihood of complications.

The method of blockade of the nerves of the accessory gonads in males of small animals is carried out in the following way. After preliminary immobilization, the animal is fixed in the dorsal position. Prepare the operating field by shearing and shaving the coat on the sides of the white line of the abdomen, retreating 2-3 cm in different directions from the ventral pubic tubercle. Then, the injection site is treated with an antiseptic solution. For anesthesia, the injection site is injected fan-shaped subcutaneously with 0.5-1 ml of a 0.5% solution of novocaine. Then, an injection needle for intramuscular injection 25G1 (0.5x25 mm) is taken. The needle is injected at the point of intersection of 2 lines on the ventral wall of the abdomen: the junction line of the hip joints and the medial line of the abdomen to a depth of 1.5-2 cm at an angle of 35-45 ° to the abdominal wall in the caudodorsal direction. The reference point is the ventral pubic tubercle and the cranial edge of the pubic fusion. 0.5 ml of a 0.5% solution of novocaine is injected.

Select 2 groups of animals, male rabbits of the New Zealand breed (mixture with white Californian) at the age of 3.5 months, with an average weight of 3.2 kg, which are divided into two groups of 10 individuals: experimental and control.

Animals of the control group, after preliminary immobilization and local anesthesia, were injected with 76% urografin from the sciatic arch laterally in the direction from the beginning to one, and then to the other hip joints to a depth of 10 mm, preliminarily sending 0.3-0.5 ml solution, advancing the needle.

The animals of the experimental group, after preliminary immobilization and local anesthesia, were injected with a needle at the point of intersection of 2 lines on the ventral wall of the abdomen: the junction line of the hip joints and the medial line of the abdomen to a depth of 1.5-2 cm at an angle of 35-45 ° to the abdominal wall in the caudodorsal direction. 0.5 ml of solution was injected.

In both groups, X-ray control was performed in two projections immediately after the administration of urografin. To visualize the urogenital canal and bladder, a subclavian catheter filled with urografin was inserted into the urethra and bladder, through which urografin was also injected into the bladder cavity. In the animals of the control group, in half of the cases, urografin was visualized outside the pelvic cavity, which infiltrated the surrounding connective tissue and muscles of the pelvic region. In the experimental group, in all cases, after injection, the solution was concentrated in the area of the prostate and vesicular glands. The next day, control X-ray studies were carried out, which showed complete elimination of urografin from the animals' body.

The proposed method for blocking the nerves of the accessory gonads was tested in laboratory conditions in the structural divisions of the Federal State Budgetary Educational Institution of Higher Education Omsk State Agrarian University:

- Department of Diagnostics, Internal Non-communicable Diseases, Pharmacology, Surgery and Obstetrics;

- Department of Anatomy, Histology, Physiology and Pathological Anatomy;

- University veterinary clinic.

The ease of insertion of the injection needle contributes to the least trauma to the surrounding tissues and hollow organs, in particular the nerves and the bladder. Reducing the likelihood of complications is provided due to the precise hit of injected solutions, which are delivered directly to the nerves of the prostate and vesicular glands.

The proposed method for blocking the nerves of the accessory gonads in small animals has a low injury rate and a low likelihood of complications.

The proposed method for blocking the nerves of the accessory gonads in small animals can be used in experimental and clinical surgery for pathogenetic therapy of the pelvic cavity organs and creating a model for blocking the nerves of the accessory gonads in small animals.
