Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

2.0K
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.

Drugs Acting on Autonomic Ganglia: Blockers

1.9K
Ganglionic blockers inhibit autonomic activity by blocking nicotinic receptors in the autonomic ganglia, suppressing impulse transmission. These blockers lack selectivity between sympathetic and parasympathetic ganglia and are ineffective as neuromuscular junction antagonists. They can be categorized into two groups:

Neuromuscular Junction And Blockade

6.2K
The site of chemical communication between a motor neuron and a muscle fiber is called the neuromuscular junction (NMJ). The end of the motor neuron at the NMJ divides into a cluster of synaptic end bulbs. The cytoplasm of these bulbs consists of synaptic vesicles enclosing acetylcholine molecules, the principal neurotransmitter released at the NMJ. The region opposite the synaptic bulb that ends in the muscle fiber is called the motor end plate, which has acetylcholine receptors. Within the...

Area of Science:

  • Interventional radiology
  • Neuroanatomy
  • Pain management

Context:

  • Advancements in understanding neural structures enable targeted neurodestructive techniques.
  • The autonomous nervous system regulates organ function and pain, making its ganglia targets for radiological intervention.

Purpose:

  • To outline the role of interventional radiology in targeting the autonomous nervous system for pain relief.
  • To discuss neurodestructive methods for afferent nociceptive pathways.

Summary:

  • Computed tomography (CT)-guided sympathetic nerve blocks are established procedures for pain associated with the autonomous nervous system.
  • Chemical and thermal ablation can irreversibly destroy sympathetic chain ganglia and autonomous nerves.
  • Techniques include sympathetic blocks, celiac plexus neurolysis, and dorsal root ganglion rhizotomy.

Impact:

  • Sympathetic blocks treat vascular diseases (e.g., critical limb ischemia), complex regional pain syndrome (CRPS), tumor-associated pain, and hyperhidrosis.
  • Celiac plexus neurolysis offers palliative pain relief for pancreatic cancer.
  • Percutaneous dorsal root ganglion rhizotomy is an option for refractory radicular pain.
