Blunt Fluid Dissection


This blog post is in response to a thread in started by a poster, “Physician.” In this thread Physician described a possible new way to perform magnet implants using blunt fluid dissection. The following is me trying to perform the method Physician described.

This is a trial of blunt fluid dissection as a means of implantation. With this method the technician administers a small amount of fluid into the skin by means of a needle and syringe. It’s essentially an intradermal injection. I’ve done many of these as it’s the method used to administer a Mantoux tuberculin test. In the case of a TB test, about 0.10ml of fluid is injected between skin layers resulting in a wheal. The next step would be to create a small incision and to place the device or jewelry into the space created. This hopes avoids sharp dissection which can harm nearby structures.



As you can see from the image above, the idea is that fluid ends up in the area beneath the epidermis. I have doubts about this method working as the bottom most layer of the epidermis, the stratum basale, is strongly anchored to the underlying basement membrane. When people form blisters the pocket of fluid is usually between the stratum spinosum and the stratum basale.

If we incise and place a magnet into the wheal formed through intradermal injection, the magnet is being placed above the stratum basale which contains the generative cells. I believe that the magnet will be pushed to the surface over time. Regardless.. I’m willing to give it a try. Whats another scar eh?

The following videos just show me practicing intradermal injections on myself.

Forearm Blunt Fluid

Finger Blunt Fluid

Sorry for the links. Can’t get them to embed for some reason. As you can see, this technique could potentially be used in the forearm. A large wheal is easily formed. Assuming I’m wrong about where the pocket of fluid is actually sitting this would be an ideal method. The finger though.. no go. I’m not sure if it’s because of the lucidum or simply due to a higher proportion of hemidesmosomes but I’ve only been able to form the smallest of wheals. Perhaps it’s related to my technique.

The next step was of course to perform a full implant using this method. I decided to go with the forearm.

The results of my trial? I found out that topical lidocaine if applied two hours before a procedure works really well but as far as I can tell, blunt fluid dissection isn’t a method I’d try again.
