Technology and features of the blockade in inflammation of the sciatic nerve

The Main symptom of sciatica (sciatica) is a pain syndrome. Localized pain in the lower back and extend to the lower limb. In milder forms of the disease effective physiotherapy treatments. However, in some cases such procedures do not provide sufficient relief, it is necessary to resort to the implementation of therapeutic blockades. Conduction blockade in inflammation of the sciatic nerve is only in extreme cases.

sciatica Treatment injections

Medication To reduce the pain, sciatica patients, as a rule, appoint:

  • novocaine
  • lidocaine
  • diclofenac
  • Movalis.

And lidocaine Novocaine blockade carried out by administering the anesthetic to a certain point with the aim to reduce pain in lesions of the sciatic nerve. The use of lidocaine is more effective than novocaine blockade. In addition, lidocaine has a lower coefficient of toxicity.

Diclofenac is a drug, by which is achieved a pronounced anti-inflammatory and analgesic long-lasting effect. It is recommended to reduce pain with sciatica. In case of severe sciatica effective only injections of diclofenac, the drug is injected intramuscularly. Diclofenac in the form of tablets, ointments, patches effective in milder forms. The dosage depends on body weight and age.

Movalis also has analgesic and anti-inflammatory effect. As diclofenac is an intramuscular injection. These drugs are effective for treating sciatica. The Movalis and diclofenac belong to the group of the strongest anti-inflammatory agents.

benefits of blockade of

  1. Therapeutic blockade provides a more effective and quick result in lesions of the sciatic nerve. The blockade is able to relieve very intense pain with sciatica, as the drug directly affects the nerve fiber.
  2. the Risk of side effects with this method of introduction is minimal. This is because the medicine goes directly to the first hearth, and then into the General circulation.
  3. Blockade allows not only ease pain but also to reduce muscle tension and inflammatory response.

Indications and contraindications

Injections are prescribed for the treatment of sciatica. To conduct therapeutic blockade is resorted to only in severe cases of neuralgia, when other methods are ineffective. The indications for this procedure are intense pain that is not relieved by other means. Drug treatment gives good result.

lidocaine or novocaine blockade has a number of contraindications. Among them are:

  • arterial hypotension
  • bradycardia
  • syndrome of weakness of sinus node;
  • cardiogenic shock
  • atrioventricular block second and third degree;
  • allergic reaction
  • severe liver failure;
  • myasthenia gravis;
  • epileptiform convulsions after administration of procaine or lidocaine in history;
  • pregnancy.

The Introduction of diclofenac and sciatica Movalis also has contraindications:

  • allergic reaction
  • pathology of the blood;
  • peptic ulcer disease;
  • inflammatory bowel disease in the period of exacerbation;
  • severe renal and hepatic failure;
  • last trimester of pregnancy;
  • breastfeeding.

With careful injections of diclofenac or Movalis prescribed to patients with coronary heart disease.

the Technique of the blockade of

Position the patient on his stomach. The blockade produced only in point Voino-Yasenetsky, which is located directly above the nerve. To find this point should hold two lines: the horizontal is held at the top of the greater trochanter and the vertical through the outside edge of the ischial tuberosity. Point is at their point of intersection, it is more convenient before the introduction of the drug to identify it with a solution of iodine.

the Location of the sciatic nerve

Dosage of drug for the treatment of neuralgia of the sciatic nerve is determined only by the doctor. The needle is injected to the specified location, then carry out layer-by-layer infiltration, gradually guiding it deep down to the sciatic nerve. You should not enter the drug intraneural, as it will lead to injury of the nerve. When performing novocaine blockade it is recommended that this method be added to the novocaine, hydrocortisone. Addition to anesthetic corticosteroid gives a more prolonged therapeutic effect.

Possible complications in the treatment of sciatica

Among the complications of the blockade for the treatment of neuralgia of the sciatic nerve can be distinguished:

  • nerve damage
  • OTL injection needle
  • damage to the vessel.

nerve Damage

In violation of art the introduction of the drug possible nerve damage. The consequences of this phenomenon – intense pain and violationsensitivity. The risk of such complications when proper injection is minimal. If the sciatic nerve damage does occur, you should immediately begin treatment. The therapy consists of injecting B vitamins, neostigmine, pyrogenal. The dosage is determined by a specialist. In addition to medical treatment, conducted physical therapy. The patient is prescribed galantamine electrophoresis and electrostimulation of the muscles. Also recommended physical therapy and massage.

OTL injection needle

The Cause of otloma needle is usually inadequate motor response by the patient in response to the injection. OTL most often occurs near the cannula. In this case, the extraction is quite simple as the end of the needle protrudes. In rare cases, removing the needles without surgery is impossible. If the needle is sterile, it will, as a rule, is encapsulated in the soft tissues and does not cause discomfort to the patient. However, possible infection, which requires surgical removal in a hospital.

vessel Damage

Injury of the vessel with the needle manifests itself in the form of hematoma. If there is a wound of the vessel, it is necessary to compassionate a cotton swab the injection site of the needle for several minutes. In compliance with the rules of introducing this complication usually does not occur. To prevent injury of the vessel to perform the injection in strict accordance with the anatomical landmarks of the sciatic nerve.

When a drug specialist these complications occur very rarely. To avoid side effects of treatment of sciatica associated with overdose, you must enter only the allowable amount of the drug. For diclofenac the maximum daily dose is 150 mg, Movalis is 15 mg.
