Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

941
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

1.6K
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...

Area of Science:

  • Anesthesiology
  • Anatomy
  • Pain Management

Background:

  • Mandibular nerve blocks are crucial for managing atypical facial pain and trigeminal neuralgia.
  • Current lateral and anterior approaches carry inherent safety risks.
  • A novel modified lateral approach is proposed to enhance safety and efficacy.

Purpose of the Study:

  • To introduce and validate a modified lateral approach for mandibular nerve blocks.
  • To hypothesize improved safety and comparable efficacy against traditional techniques.
  • To reduce procedural complications in facial pain interventions.

Main Methods:

  • Anatomical investigation using Radiology Anatomy Atlas Viewer and cadaveric slices.
  • Development of a precise needle path using axial slices at the lateral pterygoid plate and temporomandibular joint.
  • Theoretical verification and practical application in clinical practice.

Main Results:

  • The modified lateral approach was theoretically verified via reconstructed cadaveric slices.
  • The technique has been successfully implemented in clinical practice.
  • Precise needle trajectory minimizes periosteal contact, redirection, and procedural complications.

Conclusions:

  • The modified lateral approach to mandibular nerve blocks enhances safety compared to traditional lateral and anterior techniques.
  • Cadaveric anatomic reconstruction facilitated the development of this safer approach.
  • This technique addresses the increased safety challenges associated with facial intervention.
