Question

this for dental hygiene

In your own words, not copy/paste or directly from the book or other sources, provide the following: . Describe one method of administration of local anesthesia. • Provide an example of where this delivery would need to be placed to achieve local anesthesia.

Answer 1

Ans) Methods of administration of local anesthesia: Different methods include topical anesthesia, field block, ring block, local infiltration and nerve block.

- For minor surgery, a local anesthetic can be given via injection to the site, or allowed to absorb into the skin. However, when a large area needs to be numbed, or if a local anesthetic injection will not penetrate deep enough, doctors may use other types of anesthesia.

- For example, nerve blocks for hand surgery usually last for 6-8 hours, but a nerve block for pain after total knee replacement can last for 12-24 hours. Medication continuously delivered through a tiny plastic tube (nerve catheter) placed next to the nerve can last for 2-3 days.
