What is Supraperiosteal infiltration?
Supraperiosteal injection (commonly known as local infiltration) is indicated whenever dental procedures are confined to a localized area in either the maxilla or mandible. The terminal endings of the nerves innervating the region are anesthetized.
What is the difference between an infiltration and a nerve block?
Infiltration anesthesia is often used for minor surgical and dental procedures. Nerve block anesthesia is used for surgical, dental, and diagnostic procedures and for pain management.
What does infiltration mean in dentistry?
Infiltration analgesia is deposition of an analgesic drug close to the apex of a tooth so that it can diffuse to reach the nerve entering the apical foramina. It is the most routinely used in dental local treatment.
How do you do infiltration?
A common technique for local anesthesia infiltration is to inject the anesthetic solution in a circular pattern around the operative area. The doctor keeps the number of needle insertions minimal by inserting the needle in a plane beneath the skin.
How do you do local infiltration?
Why does local Anaesthetic not work in infection?
Because polar or electrically charged chemical species cannot cross biological membranes, most of the anesthetic drugs penetrates slowly or poorly in the target tissue affected by inflammation or infection.
What are the benefits of local anesthetic infiltration?
Conclusion
| Local anaesthetic infiltration method . | Advantages . |
|---|---|
| Continuous infusion catheter | Prolonged provision of analgesia; less PONV as opioid sparing; no motor block; decreases hospital stay |
| Tumescent | Simple; low cost; improved analgesia and prolong duration; allows larger dose |
How do you test for infiltration?
What are signs of an infiltration/extravasation?
- Redness around the site.
- Swelling, puffy or hard skin around the site.
- Blanching (lighter skin around the IV site)
- Pain or tenderness around the site.
- IV not working.
- Cool skin temperature around the IV site or of the scalp, hand, arm, leg or foot near the site.
