Infiltration anesthesia therapy

What Is Infiltration Anesthesia?

Infiltration anesthesia is a local anesthetic technique used to numb a specific area of the body for minor surgical procedures or other medical treatments. It is the least complicated type of local anesthesia, and it involves injections of a numbing anesthetic. This type of anesthesia only works on the area that it is injected into and has no effect on other areas of the body.

How Does Infiltration Anesthesia Work?

The anesthetic is administered directly into the tissue, typically the skin. This infiltrates the area, blocking the nerve impulses that would otherwise cause pain. Depending on the type of anesthetic used and the area of application, the effects of infiltration anesthesia can last from a few minutes to several hours.

Benefits Of Infiltration Anesthesia

  • It can provide numbness to a specific area without the need for general anesthesia.
  • It can be used for a variety of minor procedures such as biopsies, injections, and other minor surgical procedures.
  • It is not associated with the side effects that are sometimes associated with general anesthesia.
  • It is relatively fast-acting and can provide quick relief of pain.

Risks Of Infiltration Anesthesia

  • It can sometimes cause side effects such as redness, swelling, or itching at the injection site.
  • In rare cases, more serious side effects such as an allergic reaction can occur.
  • It is possible that not all of the area will be fully numbed due to blockage of the nerves.


Infiltration anesthesia is a useful local anesthetic technique, which can provide effective pain relief for minor procedures. It is a relatively safe method of providing anesthesia, but it is important to be aware of the potential side effects associated with it. As with any procedure, it is important to speak to your doctor or healthcare professional to understand all of the associated risks and benefits.
