Kauzalgiya

Description:

Kauzalgiya — an intensive thermalgia in a zone of an innervation of partially damaged peripheral nerve containing a large number of sympathetic vegetative fibers.

Kauzalgiya's symptoms:

The first signs of a kauzalgiya appear usually in 5 — 15 days after an injury, is more rare directly after it. In the beginning in a distal zone of an innervation of the injured nerve (in a brush or foot) there are paresthesias in the form of a pricking, feelings of crawling of goosebumps, then a megalgia of burning character. Several days later pain can extend to all extremity and even to a trunk. Strengthening of pain at easy tactile and pain stimulations of intact body parts is characteristic, at bright light, loud sounds, when warming an extremity. Reduction of intensity of pain when cooling and moistening an extremity therefore patients lower a hand or a leg in cold water is typical or wrap up them with cold wet fabric (a symptom of "a wet rag"). All attention of the patient is riveted on the affected extremity, he becomes emotionally vulnerable, extremely irritable, alarming and alerted. Contagious excitation sharply strengthens pain. Quite often the general weakness, weakness, pains in heart join. Symptoms of vegeto-vascular dystonia in the form of asymmetry of the ABP, lability of pulse, change of a dermographism, etc. come to light.

Vegetative and trophic disturbances in the affected extremity are characteristic: the xeroderma or a hyperhidrosis, a hyperemia or blanching of skin, strengthening or weakening of its pigmentation, increase in vascular and pilomotor reflexes, the strengthened growth of nails, a hypertrichosis, puffiness of joints, are noted muscular hypertrophies.

Kauzalgiya's reasons:

Develops in 3 — 5% of cases of partial damage of peripheral nerves: on a hand — median (is more rare than elbow), on a leg — a sciatic or tibial nerve.

Kauzalgiya's treatment:

Treatment includes purpose of analgetics, sedative drugs, Finlepsinum, indometacin, ganglioblokiruyushchy means, physiotherapeutic procedures (an electrophoresis with analgetics, amplipulsetherapies, UVCh-therapies, an electrosleep, an electroanalgesia), carrying out psychotherapy, hypnotherapy, acupuncture, novocainic blockade sympathetic ганглиев. At inefficiency of medicinal therapy an operative measure can be shown.
