Here you will find:

The so-called local anesthesia (from the Greek anaisthesia - numbness) is the simplest form of local anesthesia. A small area of ​​the body, usually in the area of ​​the skin or mucous membranes, is numbed.

What happens in this process?

The local anesthetic of the surgical area is usually carried out by the doctor, who also carries out the subsequent operation, directly before the procedure.

Certain drugs (local anesthetics) are used, which have the property of blocking the conduction of pain in a nerve for a certain period of time. After disinfection, these agents are injected in a fan shape under the skin or mucous membrane in the operating field (infiltrated - hence also called infiltration anesthesia). Usually you only notice the first puncture, as the others take place in areas that are already anesthetized. After a short exposure time, the area treated in this way is completely numb and the procedure can be carried out. If you still feel something, you should inform your doctor at any time during the procedure, who can then easily intensify the anesthesia. Local anesthesia can also be applied to the eye using eye drops.

An alternative form of local anesthesia for very brief, superficial interventions on the skin can be freezing (cryo-anesthesia). A cold spray is applied that numbs the surface of the skin for about one minute. Another form is the application of local anesthetics in a cream, which has to act for 60 minutes under a plaster.

In which situations is this procedure recommended?

Local anesthesia is particularly suitable for interventions on the skin and mucous membranes such as the removal of warts, small superficial skin tumors or for closing small skin wounds.
As with all forms of local pain elimination while maintaining awareness, the method has the advantage that the patient can be addressed at any time and possible "after-effects" of anesthesia are eliminated.

Local anesthesia is often used before other procedures so that you do not notice the puncture with the thicker needles.

The use of the numbing skin creams is particularly suitable for minor operations on children who are afraid of the syringe and do not hold still.

Who is not suitable for this procedure?

The procedure must not be used in the case of allergies to the local anesthetic, otherwise there are no contraindications.

Local anesthesia is not sufficient for interventions in deeper body regions such as joints, as the anesthetics do not penetrate deep enough. Other procedures are used here, such as conduction blocking (reference: conduction anesthesia), plexus blockade (reference: plexus anesthesia) or spinal anesthesia.

Difficulties can also arise with inflammation in the surgical area or with interventions on the fingers.

How is the risk to be assessed?

It is true that the narcotics are not entirely harmless when they get into the circulation. With local anesthesia, however, this is as good as impossible. The substances are broken down by the body on the spot and the blocked nerve works just as well afterwards as before.

What happens afterwards and what do you have to consider?

Even after the procedure, the area in question is still numb for some time, which most people are familiar with from dental procedures. In the case of procedures in the mouth, you should not eat anything until the anesthesia has worn off completely, as you could bite your cheek mucosa or tongue without realizing it.
