Local Anesthetics: Differential Sensitivity of Nerve Fibers

1.8K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

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

2.9K
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...

Summary

Sonoplex echogenic needles improve ultrasound-guided regional anesthesia (UGRA) for beginners. Inexperienced residents using Sonoplex needles demonstrated better needle tip visibility and faster procedure times in simulated nerve blocks.

Area of Science:

  • Anesthesiology
  • Medical Imaging
  • Surgical Technology

Background:

  • Ultrasound-guided regional anesthesia (UGRA) requires clear needle tip visualization for patient safety and procedure effectiveness.
  • Image disruption of the needle tip is a common challenge, particularly for novice practitioners.

Purpose of the Study:

  • To compare the performance of Sonoplex and Stimuplex D-Plus echogenic needles in simulated UGRA tasks.
  • To evaluate needle tip visibility and procedural efficiency among inexperienced anesthesiology residents.

Main Methods:

  • Twenty-eight anesthesiology residents performed simulated nerve blocks using both Sonoplex and Stimuplex D-Plus needles after standardized training.
  • Objective measurements included needle tip visualization time, total procedure duration, and needle insertion angle.
  • All procedures were digitally recorded and analyzed by two independent investigators.

Main Results:

  • Sonoplex echogenic needles exhibited significantly superior needle tip visibility compared to Stimuplex D-Plus needles.
  • Procedures using Sonoplex needles resulted in shorter total procedure times, especially at insertion angles between 42° and 64°.
  • Inexperienced users completed procedures more rapidly with the Sonoplex echogenic needle.

Conclusions:

  • Sonoplex echogenic needles enhance procedural efficiency and needle tip visualization for inexperienced users in UGRA.
  • Improved needle visibility is crucial for advancing UGRA techniques, particularly for novice practitioners.
  • The findings suggest Sonoplex needles are a valuable tool for improving training and performance in UGRA.
