Local Anesthetics: Common Agents and Their Applications01:23

Local Anesthetics: Common Agents and Their Applications

612
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

632
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.

Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia

1.4K
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

Local Anesthetics: Clinical Application as Epidural Anesthesia

519
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

    Summary

    Tumescent anesthesia, initially for liposuction, is now a versatile local anesthesia technique. Its safety and effectiveness have led to widespread adoption across numerous surgical specialties.

    Area of Science:

    • Anesthesiology
    • Dermatologic Surgery
    • Plastic Surgery

    Background:

    • Tumescent anesthesia was developed as a safer alternative to general anesthesia for liposuction.
    • It involves injecting a dilute solution of lidocaine and epinephrine in saline into subcutaneous fat.
    • This technique provides local anesthesia, hemostasis, and vasoconstriction.

    Purpose of the Study:

    • To review the fundamental principles of tumescent anesthesia.
    • To explore the expanding range of surgical applications beyond liposuction.
    • To highlight the advantages of tumescent anesthesia over general anesthesia.

    Main Methods:

    • Review of existing literature and clinical practices.
    • Discussion of the basic technique and its components.
