Parascalene block, a brachial plexus anesthetic technique, was studied to assess its safety regarding pneumothorax. The study found the needle entry point is safely above the pleura, minimizing pneumothorax risk.

Area of Science:

  • Anesthesiology
  • Radiology
  • Anatomy

Background:

  • Parascalene block is a brachial plexus anesthetic technique.
  • Minimizing pneumothorax risk is crucial for this procedure.
  • Accurate needle placement is key to patient safety.

Purpose of the Study:

  • To define the parascalene block needle position relative to the brachial plexus and pleura.
  • To evaluate the potential for pneumothorax during parascalene block.
  • To determine if parascalene block can minimize pneumothorax incidence.

Main Methods:

  • Computed tomography (CT) was used to visualize needle placement in 10 patients undergoing parascalene block.
  • Markers were placed in 10 volunteers at the intended needle insertion site for CT analysis.

  • Measurements of skin-to-groove and groove-to-rib distances were taken at the needle insertion level.

    • Main Results:

    • CT imaging confirmed the needle insertion or marker level was superior to the dome of the pleura.
    • Average distance from skin to interscalene groove was 17 +/- 4 mm.
    • Average distance from interscalene groove to the first rib was 15 +/- 3 mm.

    Conclusions:

    • The parascalene block needle entry level is consistently superior to the pleura.
    • This anatomical positioning suggests a minimized risk of pneumothorax.
    • Parascalene block offers a potentially safer approach for brachial plexus anesthesia.
