Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

1.8K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

1.9K
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

2.5K
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:

  • Pain Management
  • Interventional Radiology
  • Anesthesiology

Background:

  • Ultrasound-guided cervical nerve root block (US-CRB) is a common treatment for radicular pain.
  • Previous studies show conflicting results regarding the spread of injected solutions during US-CRB.
  • Understanding injectant spread is crucial for optimizing US-CRB efficacy and safety.

Purpose of the Study:

  • To investigate the spreading pattern of injectants in ultrasound-guided cervical nerve root block (US-CRB).
  • To determine the relationship between injection volume and the spread of contrast medium.
  • To assess the clinical outcomes of US-CRB in patients with mono-radiculopathy.

Main Methods:

  • Prospective case series of 53 patients with mono-radiculopathy (C5-C7).
  • US-CRB performed with fluoroscopic confirmation and in-plane needle approach.
  • Contrast medium (1 mL and 4 mL) injected to assess spread; followed by local anesthetic and corticosteroid.

Main Results:

  • 1 mL contrast did not spread into the epidural space.
  • 4 mL contrast spread into the intraforaminal epidural space in 24.5% of patients.
  • All patients experienced pain improvement, with no significant difference based on spread pattern.

Conclusions:

  • Injectant volume partially influences the spread pattern in US-CRB.
  • Further research is needed to explore other factors like needle position and physiological effects.
  • US-CRB remains an effective treatment for radicular pain, with consistent outcomes observed in this series.
