Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

359
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.

Area of Science:

  • Dentistry
  • Oral and Maxillofacial Surgery
  • Anesthesiology

Background:

  • Trismus, characterized by restricted mouth opening from muscle spasms, presents challenges in oral functions.
  • It can arise from various causes, including post-surgical complications, intramuscular injections, and local anesthesia issues.
  • While local anesthetics are generally safe, trismus is a recognized side effect requiring management.

Observation:

  • A case of trismus occurred following an inferior alveolar nerve block.
  • The patient experienced restricted mouth opening, pain, and edema.
  • This complication impacted essential oral functions.

Findings:

  • A comprehensive, multifaceted treatment strategy was implemented for the trismus.
  • The management approach led to significant improvements in mouth opening.
  • Reductions in pain and edema were also observed following the intervention.

Implications:

  • This case highlights the effectiveness of a multifaceted treatment strategy for managing trismus.
  • Early and appropriate interventions are crucial for improving patient outcomes in such cases.
  • Understanding and addressing trismus post-anesthesia is vital for dental practitioners.
