This study introduces a cost-effective method for brachial plexus block anesthesia using a standard electrostimulator and a conductive plastic cannula. This technique offers a reliable, safe, and easy alternative for forearm and hand surgeries.

Area of Science:

  • Anesthesiology
  • Neurosurgery
  • Medical Devices

Background:

  • Brachial plexus block is essential for forearm and hand surgeries but can be unreliable due to anatomical variations.
  • Conventional methods often require specialized, expensive equipment.
  • Previous techniques, like Greenblatt's, utilized specific plastic-coated needles.

Purpose of the Study:

  • To describe a novel, cost-effective technique for brachial plexus block.
  • To evaluate the reliability, safety, and ease of use of this new method.
  • To offer an alternative to specialized needles using conventional medical supplies.

Main Methods:

  • Utilized an electrostimulator in conjunction with a standard, conductive plastic cannula (intended for intravenous use) and obturator.

  • Compared the efficacy and practicality against specialized needles previously described.
  • Applied the technique for anesthesia in surgical cases involving the forearm and hand.

    • Main Results:

    • The described technique achieved complete and reliable nerve blockade.
    • The method proved to be safe and easy to perform.
    • The use of a conventional cannula significantly reduced costs compared to specialized needles.

    Conclusions:

    • A conventional plastic cannula with an electrostimulator provides a reliable, safe, and economical approach to brachial plexus block.
    • This technique offers a practical alternative for anesthesia in upper extremity surgery.
    • The findings suggest wider adoption of this simpler method could improve accessibility and reduce healthcare costs.
