Blockade of the cervical spine: the effects, how is

Blockade of the cervical spine is a method to relieve pain in pain syndromes of the roots. The great blockade relieves the pain by stopping the conduction of impulses by nerve fibers. Depending on the site of blockage, the effect will vary, because it is necessary to put a point and a skilled hand. Holding a blockade in the home is impossible because of the requirements of professionalism and sterility of holding. If unsuccessful blockade may develop suppurative lesions of the spinal cord and its membranes, which endangers a person's life. Blockade the lowest number of contraindications, which makes it a universal method in the fight against pain.

Constant pain dangerous not only reduced quality of life, but also the formation of the pain focus in the brain of the person. It is a group of bodies of nerve cells, which with constant exposure to have its own induction, which can cause the activity of neurons. This phenomenon is called epileptic seizures and extremely dangerous to humans because of the uncontrollable painful condition.

What is the blockade

The blockade represents an injection of sodium blocking substances in the neck, in the body of a nerve or the spinal ganglion. Part of the blockade normally use lidocaine or novocaine mixed with saline solution. In addition, the composition can be drugs, vitamins, and other substances that are needed for therapy. The principle is based on the blockade of sodium channels work. The impulse in the nerve cell is formed due to the difference of electric potential inside the membrane and around it. If irritation occurs, for example, pressure or other impetus, the cell potential starts to change. For certain values starts to enter the sodium, which continues the process of creating momentum.

Lidocaine and novocaine are the atoning work of blockers of sodium channels. Getting into the environment of the cell, they block the expansion of channels and pumps, which leads to the suppression of the creation of the nerve impulse.

Pain is inherently strong impulses emanating from the cells in the brain. In the absence of the ability to create a pulse of pain produced by tissue lost. The choice of drug is repelled from the character of the pain. Lidocaine is a strong blocker with smaller time steps, it is suitable for emergency relief severe pain. Novocaine, on the contrary, approximately one and a half times the period of weaker while the peak accumulation in cells, because it is perfect for weak syndrome, requiring long-term pain relief.

The method has long been used in neurology and anesthesiology. To use the blockade is necessary to know the location of nerve roots and their projections on the human body. They are held only by doctors, Junior and middle medical personnel in this case is allowed only for retention of the patient.

The treatment uses sterile tools needle and syringe. Lock uses a special thin and elongated needle, which allows for the most painless to enter in the tissue surrounding the spine. The solution itself is also sterile, which eliminates the possibility of ingress of microorganisms into the spinal cord. For the conduct of the blockade requires sterile conditions, which is achievable in the hospital. Put the blockade in the treatment room or small operating doctor in the presence of the nurse or of the nurse. Patients with acute pain can tie in the couch to avoid the possibility of breaking the needle in the man.

When is

The blockade is a universal means of pain relief. It is used not only in case of osteochondrosis and hernias, but can be the anesthetic technique for carrying out local operations. Depending on the purpose, mode and place of introduction of strongly differing.

The indications for staging the blockade:

  • Pain syndrome due to a pinched nerve;
  • Diagnostic procedures in which pain interferes with the conduct of the survey;
  • As anesthesia for some surface operations that do not require General anesthesia;
  • As a therapy, together with the introduction of medicines and vitamins.

Pain in lesions of the neck, such as degenerative disc disease, osteoporosis or herniated hinders the recovery of the patient and reduces the quality of life. The blockade is a versatile tool for the treatment of diseases of the neck,as a full-fledged relieves pain and does not develop painful lesions in the brain.

Blockade usually put courses and want to appear in the hospital outpatient, or take a full course of treatment in hospital. The second option is more preferable because the human behavior after the blockade can be greatly diminished due to the lack of nerve impulses and proper rest.

In some cases, especially when the cervical intervertebral hernias, the person experiences terrible pain and does not fully carry out x-rays or ultrasound of the neck. To do this, conduct a diagnostic blockade. The pain goes away and the patient's condition is normalized. In addition to the standard mixture there can add a certain amount of safe contrast. The contrast provides a better look at the x-ray and ultrasound damaged tissue. It consists of oxides of metals that are in the pictures highlighted in black. Surrounded by a similar substance that the tissues are on the x-ray clearly visible, it becomes possible to estimate the size and shape. To diagnose the extent of damage is very useful and gives accurate data for diagnosis.

Operations that do not require penetration into deeper tissues of the body it is available under the blockade. For example, removal of cervical Wens or benign tumors of fatty tissue on the neck. Another indication for the blockade at the time of surgery can be a great age of the person, which may due to the weak cardiovascular system not to move a full anesthesia with the introduction of the anesthetic state.

Therapeutic blockade are a mixture of vitamins and medication. By introducing directly in the diseased nerve tissue of the neck, the drug and vitamins begin to act and assimilated as quickly as possible, bypassing the intestinal tract and blood. Some medications have a poor level of capture proteins, because their introduction is only possible intramurale.


The question of the necessity of the blockade is only your doctor who knows the full history of the patient. It has its contraindications, which if disregarded can lead to the development of side effects. Contraindications are divided into absolute and relative.

Absolute contraindications that preclude the procedure, include:

  • Epilepsy in anamnesis;
  • Neurological reactions to pain;
  • Pathological changes in the liver;
  • Myasthenia gravis and heart disease.

Epilepsy is an absolute contraindication because of the weakness of the human nervous system. Introduction blockers in nerve tissue can trigger the processes of spontaneous activity of nerve cells and epileptic seizure, which a dangerous failure of the heart and lungs. To eliminate pain in people with epilepsy use other methods – anti-inflammatory drugs and local anesthetics.

Neurological disorders hinder the work with the nervous system. With the development of multiple sclerosis neural activity becomes erratic, resulting in unpredictable reactions to drugs. The introduction of drugs directly into the nervous tissue can lead to spasms and cramps, increased pain, and problems with internal organs.

Same can be said about dementia. Dementia is similar to multiple sclerosis – on the sheath of nerve fibers is destroyed fatty tissue that helps in the rapid impulse conduction along the nerve. Often momentum is lost before reaching the brain. Disabling the functioning of the nervous tissue can trigger the process of demyelination on tissue.

Both drugs are metabolized by the liver. Despite the conditional safety of the drug in hepatitis, steatosis, or fat embolism liver any dose can become a strong threat. The load is greatly increased and leads to further chain malfunction due to overload on. Lidocaine, procaine and other blockers cause problems in the functioning of the heart. Myasthenia gravis, myocardial and other heart diseases are a contraindication for carrying out blockades and other types of anesthesia and anesthesia. Blockers can cause problems in the functioning of the heart due to blockage of sodium channels and arrhythmias. Such a violation can lead to heart failure and death.

Relative contraindications include those in which the blockade of the cervical plexus must be justified by the risk. There are the following relative contraindications:

  • Pathology in the structures of the bone;
  • Inflammation in the skin and the subcutaneous fat;
  • The individual characteristics of the disease, which is the blockade.

To pathologies mainly include osteoporosis and osteolytic. Osteoporosis is a disruption of bone, which destroyed the originalbone structure. This happens due to the reduction in the amount of calcium. Statement of the blockade on the neck can lead to exacerbation of the process, which greatly affect the work atlantization joint and will lead to deterioration.

Osteomyelitis is a suppurative disease of the vertebrae and surrounding tissues, particularly muscles. When setting the pus can get into the nervous tissue, causing an abscess and her death. The restoration of the nervous tissue takes a long time and requires expensive treatment that is not available to everyone.

Inflammation of the skin the contraindications are similar to osteomyelitis. When injected pus deeper processes begin to develop by leaps and bounds. This will cause the gain of the abscess and the level of suppuration in the tissue, which complicates treatment. In contrast to the extremities, with strong development of gas gangrene, amputated tissue around the neck is impossible. To the individual include those that were caused by coincidence of different diseases. For example, in osteochondrosis not always possible to conduct the blockade is necessary to gain access to the nerve or muscle, however, developed chondrocytes changes around the vertebrae can prevent this. Spearing them is not always advisable, because it can cause an aggressive development of the disease.

The process of conducting

Before the procedure it is advisable to eat two to three hours a light meal. This will add to the blood a sufficient amount of glucose and will not lose consciousness with unpleasant sensations. Do not fill the stomach with plenty of protein – this will create a burden for the liver and for these drugs is undesirable.

If the procedure is performed on an outpatient basis, it is advisable to get to the place, not behind the wheel – after the procedure possible recoordinate movement of the muscles, that may lead to an accident. You can walk to the hospital on foot, and if not – better to arrive by public transport or taxi.

Before the needle is inserted the patient is placed on the abdomen so that the whole neck was in easy reach. You need to be naked from the waist up, but the bra can be worn. The neck on a hard pillow. After this, the injection site palpate for the presence of infiltrations, and in their absence is disinfected.

After that, the syringe is typed first, the required dose calculated by your doctor. Then get to the total mass volume of sterile physical solution and any other drugs required for injection. A physiological solution is necessary for better acceptance of drugs by the cells, because copying their internal environment, preventing wrinkling or swelling. After that, the needle is gently withdrawn, again treating with antiseptics the injection site and apply the cotton with the alcohol solution. After that, the patient will need 3-5 minutes to get up, in order to give the tissues to heal. It is advisable not to leave the hospital within 20-30 minutes to let the medicine act in the case of side effects to tell the doctors.

In General, the procedure does not take much time and is not difficult to conduct with the technological side, however, it requires a physician of large experience in dealing with a syringe and knowledge of the anatomy of the neck. However, almost every doctor with an experience of more than a year can independently conduct the blockade, because it is not necessary to worry.

In the case of hospital treatment the procedure becomes easier, because after you conduct you do not have to go home, you can lie down on the bed and relax. The pain recedes almost immediately as lidocaine and novocaine are medicines quick action. Do not contact with this request to inexperienced doctors, because ignorance of the location of the roots can lead to serious consequences. The blockade alone in the home can be done due to the lack of sterile conditions. Therefore don't be afraid of the procedure – it is painless and does not have a strong contraindications.
