Anesthetic drug is injected directly into the tissue surrounding a specific area, usually near nerves, to numb a small part of the body.
This technique is commonly used for minor surgical procedures, dental work, or when treating injuries that require stitching or other minor interventions.
Here’s how infiltration anesthesia typically works:
1.Injection: The anesthetic, such as lidocaine or another local anesthetic, is injected into the tissue surrounding the area where pain relief is needed.
2.Numbing Effect: The anesthetic blocks nerve impulses in the targeted area, leading to temporary loss of sensation.
3.Onset: The numbing effect usually begins within minutes, allowing the procedure to be performed without causing pain.
4.Duration: The anesthesia typically lasts for a short period, ranging from 30 minutes to a few hours, depending on the specific anesthetic used and the amount injected.
This technique is generally safe and has minimal side effects, although there might be some localized swelling, redness, or slight pain at the injection site.
