Overview of common injectable anesthetics and tips on how to draw them up and inject them using a pig’s foot for practice. To learn a significant amount of information for suturing lacerations, including which instruments and items are needed to close wounds and where to buy them, suture needle sizing, the timing of suture removal, along with recommended non-surgical options for wound closure, click the link below. The link is for a hospital grade suture kit and contains a wealth of information on suturing.

There are a few injectable anna stakes that you’d like to be familiar with lidocaine also known as xylocaine that’s its trade name is the most often used one for anesthetizing wounds before you close them with sutures one percent lidocaine is the most commonly used two percent lidocaine is used for digital block lidocaine with epinephrine you can see here with the

Red label is only to be used in certain parts of the body when you inject lidocaine with epinephrine into an area like that that’s bleeding the skin edges will turn white and stop bleeding this will help you close the wound if it’s a wound on the arm or leg it’s usually okay to use and it comes in a one percent concentration another medication called marcane comes

In a 0.25 and a five percent and it’s useful if you want to extend the anesthesia to say six hours or so lidocaine will begin working within five minutes and usually lasts up to two hours whereas marcane won’t begin working until at least 30 minutes after it’s injected this limits its use as a sole anesthetic and usually what we do if we want prolonged analgesia

Say five minutes to six hours is we’ll mix in a 50 50 ratio lidocaine in either one or two percent with marking 0.5 or 0.25 percent if we have bleeding it’s a safe area to use we can inject lidocaine with epinephrine this will help slow down the bleeding and also create a white area around the injection site and by looking at that white area you can tell that

That area is already numb and it’s safe to put a suture in and the person won’t feel it you’d want to use a large needle like this 18 gauge needle to draw the medicine out of a bottle especially a large bottle like this if you use a small needle like a 25 gauge needle you’ll spin forever trying to draw it up from a bottle because of its small bore size so what we

Generally do is use a large bore needle like an 18 gauge needle to draw the medicine up and then a 25 gauge needle to actually use to inject the patient and they’re switched out after drying by using a lure lock syringe you’ll see at the end of this syringe that there’ll be a hub where the needle will hook into the syringe and keep it tight in order to drop the

Medication we’ll first take our bottle and clean it with an alcohol swab this will kill most of the bacteria on the rubber stopper then we’ll find a syringe a 5 or 10 cc syringe and affix it to our 18 gauge needle if the bottle is a glass bottle as this one is we’ll have to inject the same amount of air as cc’s of fluid that we are going to remove otherwise

We’ll create a vacuum once i’ve fill the syringe i’m going to remove the 18 gauge needle and put on the smaller bar 25 gauge needle that we’ll use to inject the patient’s wound if the multi-dose vial that we’re withdrawing from already has a protective plastic cap on top and you flip it off for the first time then you don’t need to cleanse the top with alcohol

You only cleanse with alcohol when you’re using it a second or third time later on down the road this is the difference between multi-dose vials and single dose files smaller vials are usually marked single dose and what that means is that you can only use them once and then have to discard them for the prepper it’s much easier to have multi-dose files large 50ml

Vials like this one they can be used over and over again i think our patient is about thought out here and we’ve made a linear incision this simulates in the laceration that may occur in the field and we’re going to numb up the skin edges with lidocaine we have a 25 gauge needle and a 5cc syringe full with one percent lidocaine the trick is to start at the very

Edge and the most proximal area that way when you inject and i’m slowly injecting perhaps you can see a wheel forming this is where the fluid is forming up under the skin if you inject that this way and then march forward you can see that you will only be placing the needle inside areas that are already numbed up and thus the person won’t feel the needle stick

But once you see how it puffs up now if you’re using lidocaine with epinephrine this entire area will become white because it’s closed down the blood supply there and that’s how it helps stop the bleeding process from the skin edges next we’ll repeat the process on this side marching up one after the other so that the patient does not feel but one injection if

We use lidocaine with epinephrine well note that this entire area on both sides is white and it’ll also be numb when we test it once it’s done once it’s white you’re ready to start your laceration repair foreign
