Anesthesia Endoneural

Endoneural anesthesia is a method of pain relief in which an anesthetic is injected directly into the nerve. This method is used in dentistry, especially when removing wisdom teeth and other complex operations on the jaws.

Endoneural anesthesia has a number of advantages over other methods of pain relief. First, it provides a longer-lasting effect because the anesthetic remains in the nerve for several hours. Secondly, it avoids the side effects associated with other pain management methods, such as headache, nausea and vomiting.

To carry out endoneural anesthesia, a special syringe with a thin needle is used, which is inserted into the nerve to a depth of 2 mm. An anesthetic is then injected into the needle, spreading along the nerve and blocking its transmission of pain signals.

However, like any other method of pain relief, endoneural anesthesia may have some risks. For example, incorrect needle insertion can lead to nerve damage or other complications. Additionally, this method may be less effective than other pain relief methods, especially for complex jaw surgeries.

In general, endoneural anesthesia is an effective method of pain relief and can be used in a variety of situations where long-term and safe pain relief is required. However, before using it, you should consult your doctor to make sure it is safe and effective for your particular case.

Endoneural anesthesia is an infiltration anesthesia in which an anesthetic is injected into the subendoneural space in the area of ​​projection of the nerve trunks. In most cases, pain relief is performed under ultrasound guidance. For infiltration anesthesia, isotonic (or preferably hypertonic 0.45% or remifentanil) solutions of local anesthetic in combination with antispasmodics (darmifen, dibazol) are used.

Predisksana and distal parts of the limb that are subject to surgical treatment, without straightening the limbs in the joints, begin to anesthetize from the proximal part of the limb. Each subsequent nerve root, after the previous one has been anesthetized, is given the opportunity to become an innervated surface. The intersections with the ankle joint and small bones of the foot are anesthetized. The anesthesiologist uses his fingers to probe the areas where the nerves exit. The position of the anesthetic tube when administering anesthetics is selected so that it is located behind the projection of the nerve. It is advisable to rotate the tube several times to achieve the effect. In the future, as the tunnel fills, it is necessary to add a local anesthetic, and so on until the entire distal area of ​​the hand is completely anesthetized (with anesthesia of the hands). Infiltration is best done in three stages. To do this, half the dose of local anesthetic is administered in the last session. This increases the amount of anesthesia between stages and improves the quality of analgesia. When the anesthetic tube is located behind the projection of the nerve branch, remove it completely. It is not always possible to achieve anesthesia of the largest branch. Then you can try to remove the tube on the other side and administer local anesthesia at a different angle of insertion. Sometimes it is necessary to remove the tube and inject an even larger dose of local anesthetic into the surrounding soft tissue. With this method of administration, local anesthetics are in such concentrations that they quickly deplete. Approximately 75 ml of local anesthetic solution is first injected in one go. If the leg remains cool, after 3 minutes another 50 ml is infiltrated. As a result, approximately 150–180 ml of the total injection volume should be injected over 3 times. The duration of anesthesia for such nerves is about 8 hours. If infiltration under the control of the nerve was carried out correctly, the anesthesia will be uniform and will allow the patient to keep the entire foot relaxed and keep the foot in the upper position. Subcutaneous injection is most often used to numb the fingers. Even with this technique, it is sometimes possible to achieve uniform pain relief. When anesthetizing a finger, a careful approach is required. Anesthesia is completed by introducing the infiltrate into the deeper perineural tissues of the muscles of the sole of the foot. There is a need for the infiltration solution to slowly appear from the distal end of the injection, then stop. This distance should always be two fingers. Before removal of the needle, remote insertion into the peripheral nerves is performed. This technique falls within the competence of a neurologist. Then a sterile sterile dressing is applied
