Disclaimer. I am not a licensed health practitioner. This is just another post on knowledge and understanding you might wish to acquire in advance of a disaster in case no higher care is available. As long as our society is functioning, you should leave anything more substantial than applying a Band-Aid to the professionals. No medication, including those available over the counter, should be taken without consulting a physician. Information shared here is for educational and entertainment purposes only. It is not medical advice nor a substitute for licensed medical care.
Just to reiterate the disclaimer, this is a post on supplies and knowledge you want to have before you need it. Everything about making injectable lidocaine should only be done by a licensed physician or pharmacist or under their direction and supervision.
The instructions for making injectable lidocaine when our society has totally collapsed and there is no higher medical care available were first posted online in 2013. A few years later a physician reviewed those instructions and added his own comments. (Addresses for those articles are provided below. I provide addresses rather than links because sometimes a link will disappear, but with an address it may still be possible to track down the desired article. I've had that happen quite a few times.)
Making injectable lidocaine is not at all complicated, but it is important to be careful and very precise. It is easy to overdose a patient with lidocaine. You want to avoid that.
Let's assume you already have scissors, a surgical clamp of some sort, and a candy thermometer or similar, as well as the lidocaine HCL, as was covered in an earlier post. Here are the additional supplies you'll need:
- Sterile saline. Preferably labeled as being for injection. But that can be hard to come by for unlicensed individuals. A grid-down, out in the wilderness hours or days away from a hospital solution is the single-use vials of sterile saline mentioned last week.
- Scale that can accurately measure milligrams. Digital scales start at about $20. Non-electronic scales start around $30. I have no experience with either yet. A lot of reviewers on Amazon indicate that they use both scales for reloading ammunition. If you have someone like that in your family, and they have a scale, I would love to have confirmation that their scale (with brand and model information) will accurately measure minute quantities of powder.
- A very small funnel to transfer the lidocaine HCL into the bottle of sterile saline.
To make a 1% lidocaine HCL solution:
- Weigh 150 mg of lidocaine HCL on the scale.
- Cut off the top of a 15 ml sterile saline vial about halfway down the neck.
- Insert the funnel securely into the neck of the vial.
- Pour the lidocaine into the funnel. (If the powder sticks to the funnel, squeeze the vial gently to move some saline into the funnel. Then release so that the saline drains back into the vial, taking the lidocaine with it. You may have to repeat this procedure a few times to get all the lidocaine into the vial.)
- Remove the funnel.
- Close the neck of the vial using your surgical clamp.
- Weigh 300 mg of lidocaine HCL on the scale.
- Follow steps 2-6 above.
- Create a double boiler with a small canning jar almost filled with water placed in a pan of water over the stove. You just need clean tap water; it doesn't need to be sterile or distilled.
- Place the vial in the canning jar, but be especially careful not to submerge it near the openings. Do not let any tap water enter the vial, which would contaminate the solution.
- Heat the water past 176 degrees Fahrenheit. (Lidocaine dissolves in water, but it doesn't melt until it reaches 176 degrees F. Melting ensures even distribution.)
- Remove the vial from the jar. Do not remove the clamp.
- Let cool.
- You now have a 1 or 2% solution of lidocaine HCL.
- This solution should be used within 24 hours and discarded thereafter.
To use this solution, with the clamp still in place, clean the top of the vial with an alcohol pad. Invert the vial, insert the needle through the top of the vial, and draw out the desired amount of lidocaine into the syringe.
