Description

The invention relates to veterinary therapy, namely to the treatment of cats in the postoperative period. Its most effective after osteosynthesis of the humerus and bones of the forearm of cats after fractures.

Known electrostimulation of reparative processes in the bone tissue of cats after osteosynthesis, aimed at maintaining electronegativity in the area of damage, which was created by implantation of the cathode in the area of damage and the anode cutaneous. Modeling of dynamic electric potentials is realized by passing electric current pulses between the main electrodes through newly formed bone tissue with a current strength of 25 μA and a pulse frequency of 1 Hz (1).

The main disadvantage of the above method of stimulating postoperative processes in damaged bone tissue is the additional operational work of implanting the cathode directly into the area of the bone fracture, which in the future can cause discomfort to the animal during the reparative period of the bone, as well as various inflammatory processes.

The objective of the proposed method of stimulating reparative processes in the bone tissue of cats after osteosynthesis is to increase the effectiveness of the treatment by reducing the time of bone repair, respectively, reducing the time spent by the pin in the bone, which, in turn, reduces the possibility of osteomyelitis due to prolonged contact of the bone tissue with the pin, reduce the cost of medicines, reduce the drug load on the body during bone repair.

The problem is achieved due to the fact that in the known method, which consists in exposure to electric current, according to the invention, the effect is on biologically active points (BAP) No. 1, 2, 3 with a direct current of 0.95 units of an individual sensitivity threshold with a polarity change of 0, 1 second with a duration of one session of 2-3 minutes per day and the course of exposure - 5-7 days.

To clarify the essence of the proposed method presents a drawing of a cat, which shows biologically active points:

1 - proximal of the ulnar tubercle, the lateral surface of the epiphysis of the humerus, above the ulnar tubercle, symmetrically;

2 - on the dorsal surface of the proximal epiphysis of the radius, distal elbow joint, symmetrically;

3 - on the dorsal surface, proximal to the angle of the elbow joint, symmetrically.

The stimulation of reparative processes in bone tissue according to the proposed method of electropuncture reflexology is carried out using a device such as PERT-5.

Example 1. A cat aged 1.2 years, live weight of 3.5 kg. An operation on osteosynthesis of the radius and ulna was performed. In order to stimulate reparative processes in bone tissue, the PERT-5 device was used. The maximum current reaches at zero resistance up to 500 μA, and the minimum exposure current is 10 μA. The power source is a “Krona” type battery with a voltage of 9 V. The impact on osteoreceptors of damaged bones was conducted through biologically active points No. 2 and No. 3.

Before applying electropuncture reflexology, the coat at the site of the localization of biologically active points No. 2 and No. 3 was cut and shaved. To stimulate bone repair, the negative electrode was fixed with a metal clip on the pre-humeral fold, which was also cut and shaved. The positive electrode was fixed on the skin at the location of the BAP of the damaged bone by touching and an initial current of positive polarity of 300, 250 and 200 μA was applied.

The influence on the BAP receptors of the skin No. 2 and No. 3 was carried out as exciting (duration of pulses of electric current of positive and negative polarities in a ratio of 1: 1), and inhibitory (in a ratio of 3: 1) techniques. The initial current strength of positive polarity with its gradual increase was determined by the appearance of anxiety cat. The exposure was carried out once a day by electric current with a force of 0.95 units of an individual sensitivity threshold with a polarity change of 0.1 second with a duration of one session of 2-3 minutes and a course of exposure of 5-7 days.

As a result, it was found that biological functions that contribute to the restoration of the integrity of damaged cat bones are enhanced.

Example 2. Cat at the age of 2 years, live weight of 3 kg. An operation on osteosynthesis of the humerus. In the postoperative period, the stimulation of reparative processes in the humerus was carried out according to the above scheme, but they affected the osteoreceptors of the damaged bone through biologically active point No. 1.

The proposed method was successfully applied on 15 cats during their postoperative treatment after osteosynthesis of bones on the basis of the research medical diagnostic and veterinary center Orel GAU and other clinics of the Russian Federation (see table). The method allows to do without attracting highly qualified specialists, the use of protective clothing, expensive equipment, while labor costs for its maintenance are reduced, reparative processes in the damaged bones of cats are stimulated, and the time spent on stimulation is reduced to 2-3 minutes.

In addition, the proposed method allows to reduce the time of bone repair, respectively, to reduce the time spent by the pin in the bone, which, in turn, reduces the possibility of osteomyelitis due to prolonged contact of the bone tissue with the pin, to carry out treatment without the use of medications and reduces the drug load on the animal body during reparative period, which significantly increases the effectiveness of postoperative therapy.

As can be seen from the table, the proposed method is more effective than the known one.

The proposed method allows to restore support function and form bone marrow in cats after osteosynthesis 2-3 days earlier than in the known method.
