The radial nerve - is a long radial nerve plexus innervating the muscles of the back surface of the hand, the skin surface of the lower half posteroexternal shoulder, forearm and hand. This mixed nerve which comprises a motor and sensory nerve fibers. Among the nerves of the hand radial nerve is affected more than others.

Reasons for radial nerve entrapment

The radial nerve is restrained mostly in wounds and fractures of the shoulder, sometimes the forearm, while squeezing the nerve in his sleep Dreams: how to understand our dreams Especially while intoxicated (sleep paralysis, drunk paralysis), when walking on crutches (spike paralysis), with long-lasting hold hands to the operating table during surgery under general anesthesia, as well as in long-term compression of medical instruments (hooks) during the operation at the point of passage of the nerve.

The nerve can also be diminished tumor located in the surrounding tissues or own a benign tumor A benign tumor - is not always safe   nerve (neuroma). Malignant tumors of the radial nerve are extremely rare.

Infringement of the radial nerve can be primary (due to injuries, crushing its own tumor) and secondary (with the involvement of nerve scarring, squeezing his tumor that develops in the surrounding tissues, tissue edema, plaster cast).

Symptoms

If the infringement of the radial nerve in the arm extensor function falls shoulder, forearm and hand. Forearm is bent towards the shoulder, wrist droops, and the fingers are half-bent position.

Upset sensitivity observed infringement of the radial nerve at the back of the shoulder, forearm, on the rear half of the radial brush (big toe side) adjacent to the hand and the middle phalanx I, II and part III fingers. Through connections with other nerve disorders, these much smaller area of ​​the zone of innervation of the skin.

If the infringement of the radial nerve in the middle and lower third of the shoulder and the upper third of the forearm function triceps muscle stored appears paralyzed extensor digitorum only phalanges adjacent to the brush and extension of the middle and end phalanges partially preserved through the work intercostals muscles.

Depending on where the infringement could be affected, and triceps. If it affects the nerve in the wrist affected the final branch of the radial nerve, which contains a lot of vegetative fibers (they innervate the blood vessels), in connection with which there is swelling, cold and blue back of the hand. Pain while extremely rare.

The procedure for recovering the function of the muscles in the regeneration of the radial nerve is the following: the extensors of the hand, the common extensor digitorum, longus, abductor thumb.

Diagnostics

When the extensor paralysis may also suffer wrist flexor function, which often leads to misdiagnosis simultaneous destruction of median and ulnar nerves, so it is important to clarify the diagnosis by means of special tests.

Test first. Both hands palms close to each other so that all the fingers of the same name came in contact. When the distance fingers good hand from the fingers on the side of the patient affected nerve is marked palmar flexion of the fingers.

The second test. At the request of a doctor or to shake hands with his fingers into a fist enhanced flexion posture droops brush.

Treatment

Treatment of radial nerve entrapment depends on the reason he was called. It can be conservative and surgical. Conservative treatment aims to restore nerve stimulation and pain. Used drugs, relieves swelling of the surrounding tissues, vitamin B B vitamins: the body useful helpers , Drugs that prevent the development of scars (eg lidasa) painkillers.

Widely used physiotherapy (painkillers and stimulates regeneration of the nerve), massage, physiotherapy, acupuncture Acupuncture - the ancient traditions in the service of modern science . In the absence of signs of recovery within two months of surgery performed (neurolysis, nerve trunk cross-linking).

When you break the nerve surgery is performed - the nerve sutured. The operation required and the tumor, causing a pinched nerve - the tumor was removed under a rising pain and symptoms of loss of nerve function. Often held neurolysis - nerve allocation of scars in order to improve conditions for its restoration and operation. Work is also neyrorafiya (accurate comparison of nerve ends and stapling using microneurosurgical equipment).

Infringement of the radial nerve are very common, so the main thing - time to pay attention to the first manifestations of the disease and seek medical advice.

Drinking Cavinton for the treatment of children in general and newborns especially controversial, despite the fact that it is almost always well tolerated. Appointed cavinton only pediatric neurologists, pediatricians, it is usually not used. But almost all experts note the high efficiency of the drug.

Cavinton - a herbal drug, it is based on a substance derived from the periwinkle plant. The main therapeutic effect Cavintonum is that it expands the blood vessels of the brain.

Features of functioning of the brain in young children

Most of the problems in childhood are associated with the fact that in utero brain cells do not get enough oxygen, which led to their defeat .  These lesions are called non-inflammatory nature of the encephalopathy, and since it occurred or during the perinatal period (twenty-eighth week of pregnancy on the seventh day after birth), it sounds like a diagnosis of perinatal encephalopathy or perinatal damage of the nervous system .  Such damage is usually long enough reflected on the child's condition .  And how quickly restore the central nervous system and recover it at all, depends on the extent of damage and how quickly was appointed adequate treatment .  Perinatal damage to the nervous system can be compensated for in the first months of life, and may remain for a lifetime, for example, in the form of cerebral palsy .

The mechanism of action Cavinton

Features of action Cavinton is that it causes a rush of blood mainly to the damaged areas of the brain and hardly increases the tide to the healthy tissue, that is not happening "steal" the affected areas of the brain that is important in the treatment of the effects of birth injury.

Furthermore, Cavintonum protect brain cells from newborn various damaging factors. A newborn baby is may be toxic metabolic products Metabolism: The basis of life of all living things   breakdown products or diseased brain tissue.

Improving cerebral blood flow causes the blood advances more easily through the blood vessels, it inhibits platelet agglutination, resulting in thrombus formation is prevented. For adult patients a property Cavinton is positive, as with age and various diseases of the tendency to thrombosis increases. In infants, this property is sometimes contraindicated for use Cavinton as after birth injury Birth injuries - than they threaten your child?   in the brain of a newborn child may be bleeding.

Indications for admission Cavinton

Newborns cavinton often prescribed for prolonged hypoxia of the brain, which occurred against the backdrop of feto-placental insufficiency, that is, against the background of narrowing of the blood vessels of the placenta. In this case, the child's brain is constantly receiving insufficient oxygen. If you have very little oxygen, the brain tissue irreversible changes. In moderate feto-placental insufficiency started in time (ie after birth) adequate treatment leads to the restoration of brain functions.

Treatment of perinatal nervous system begins in the nursing home and continue on an outpatient basis (if the lesion is small) or to a hospital, where the newborn is transferred directly from the maternity hospital.

In the course of complex treatment of perinatal nervous system includes including cavinton. It is given to newborn children in the form of tablets or as an intravenous infusion. Infusion certainly performed only in a hospital, as the intravenous administration of any drug is more effective than ingestion, and thus the side effects will be manifested to a greater extent.

Side effects when taking Cavinton

No side effects in the treatment of Cavinton little, however, they are. For example, cavinton may have a negative effect on the cardiovascular system: lowering blood pressure and disturb the heart rhythm. Therefore, it can not be used, for example, children with congenital heart disease Heart defects - time heals? .

There are side effects from the drug, and the central nervous system, it causes insomnia and headache. But in this case it is difficult to say, due to which these symptoms were: whether they are a result of a side effect Cavinton, or underlying disease. In any case, this can manifest anxiety baby, poor sleep Dreams: how to understand our dreams , Decreased appetite. Sometimes this side effect does not require discontinuation of therapy.

But if the child has some kind of allergic reaction to cavinton (eg allergic rash), it is definitely canceled.

Cavinton used to treat newborn babies, but only to the destination of Pediatric Neurology and taking into account all the indications and contraindications.
