Local Anesthetics: Common Agents and Their Applications

Local Anesthetics: Common Agents and Their Applications

Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
One of the advantages of...

Area of Science:

Dermatology
Cosmetic Surgery

Background:

Lower eyelid rejuvenation is a common aesthetic procedure.
Hyaluronic acid fillers are frequently used for correcting volume deficits and wrinkles.

Purpose of the Study:

To describe a specific superficial injection technique for hyaluronic acid in the lower eyelids.
To highlight key technical considerations for optimizing results and minimizing complications.

Main Methods:

Superficial injection of hyaluronic acid (Restylane) into the lower eyelid area.
Emphasis on minimizing injected volume per pass.
Discouragement of post-injection massage unless essential.

Main Results:

The described technique is considered technically difficult.
Minimizing volume per pass is crucial for superficial injections.
Avoiding massage can prevent increased eyelid swelling.

Conclusions:

Superficial hyaluronic acid injections in the lower eyelids require meticulous technique.
Careful volume management and judicious use of massage are key to successful outcomes and reduced adverse effects like swelling.
