Small amounts of pain can often be tolerated, but sometimes we don't want to or are unable to endure the pain associated with installing the implants we want. This kit may provide a solution.

Kit contains:

  • Single use 10ml lidocaine ampoule (AstraZeneca Xylocaine 2%, Lidocaine 20mg/mL) 
  • Sterile 25 gauge stainless steel hypodermic needle
  • Sterile Leur Lock syringe - 5ml 
  • Sterilized gloves
  • Chlorhexidine Gluconate skin prep swab

Cassox wrote this guide to performing a digital nerve block, often used when implanting magnets in the finger tips:

The term Nerve Block refers to the injection of an anesthetic directly onto a nerve to block the transmission of sensation. A few quick injections with a local anesthetic can immediately and completely eliminate the pain of broken ribs, migraines, and herniated discs for up to twelve hours. It's an underused modality. Nerve Blocks are often more effective and in many cases safer than a systemic analgesic like morphine; however, for the average physician performing such a nerve block comes with a heightened risk of lawsuit not justified by mere pain. Additionally, many physicians simply aren't called upon to perform nerve blocks often enough to feel comfortable. The exception to this is with digital nerve blocks. It's so simple and low risk to block the nerves of the fingers that no one would even consider stitching up a laceration without numbing the digit first.
There are two different approaches to a digital nerve block: the Volar/Dorsal approach and the Transthecal approach. An excellent step-by-step pictorial guide on digital nerve blocks is available online from the New York School of Regional Anesthesia, which demonstrates both techniques. Don't let this guide intimidate you though. I've seen plenty of finger laceration repairs and seldom does an ER doctor first contact the bone and then pull back. An effective digital nerve block can be accomplished simply by injecting 1 to 2ml of lidocaine into each side of the finger distal to the metacarpophalangeal joint.
Digital nerve blocks are pretty simple but do come with risk, so as always, I'm certainly not advocating that a person do this to themselves. I'm primarily writing this up because I've seen youtubes of people doing such damn bad jobs on themselves and I hope to provide those foolish enough to perform self-surgery with enough information to avoid permanent damage. Lidocaine does have a cardiac effect and so injection into a vein must be avoided. The way to ascertain whether or not a needle is in a vein is through aspiration. If one pulls back on the syringe plunger and blood enters the syringe, it's in a vein. Pull out and start over. Some nerve blocks use lidocaine with epinephrine, but this isn't good for use in fingers, so use an anesthetic only. Of course, a digital nerve block should only be performed with aseptic technique, and finally, don't force anything. If there is resistance to injection, you are likely someplace your not supposed to be.
Steps of a digital nerve block:
  1. Using blunt draw needles, draw up Lidocaine solution into a 5ml syringes and then attach a 25-gauge, 1” or less length needle.
  2. The first needle is inserted at a 45 degree angle to the skin into the appropriately cleaned webbing lateral to the finger of choice and distal to the metacarpophalangeal joint and 0.5ml of lidocaine is injected just beneath the skin. Do not remove the needle.
  3. After waiting 20 seconds the needle is advanced ¼ to 2/3 of an inch deeper. Traditionally, the needle is advanced until the phalanx bone is reached, but ¼ of an inch will more than suffice . The needle should be angled so that if it were to be fully advanced, contact would occur near the antero-lateral surface of the phalanx.
  4. Aspirate (pull back) the plunger of the syringe. If blood is aspirated into syringe, then the needle is in a vein and the procedure should be aborted and begun again at a different location.
  5. If needle is not in a vein, inject 1-2ml of Lidocaine. Resistance to injection should be small. Do not be forceful. If resistance to injection occurs abort the procedure and begin again at another site.
  6. After injecting, needle is removed of disposed of into an appropriate receptacle such as a sharps container (Gatorade bottles work well).
  7. Insert needles into the second site at a 45 degree angle to the skin into the appropriately cleaned webbing medial to the finger of choice and distal to the metacarpophalangeal joint and 0.5ml of lidocaine is injected just beneath the skin. Do not remove the needle.
  8. After 20 seconds advance the needle ¼ to 2/3 of an inch and aspirate. If blood is aspirated into the syringe, abort the procedure and begin again.
  9. If needle is not in a vein, inject 1-2ml of Lidocaine.
  10. After injecting, needle is removed of disposed of into an appropriate receptacle such as a sharps container.
Within 5-10 minutes, a person will have a completely numb finger, ready for magnet implant. Always keep in mind how exceedingly dangerous a lack of sensation is. Pain prevents us from injuring ourselves. Without sensation, one can casually lop off, burn, mangle, or otherwise destroy their finger merely through inattention. An anesthetized finger should be thought of like a sterile field: don't let it out of your sight.
