00:01 So now it's time to gather your supplies, prepare your work area, and perform hand washing. 00:08 You're going to need: 1 or 2% lidocaine (I would use caution with using lidocaine with epinephrine in it), 25 to 27 gauge needle, 3 to 5 cc syringe, your chlorohexidine or your Betadine (remember to check for allergies), sterile gauze, your marking pen, and gloves. 00:32 Because this procedure involves needles, you want to make sure that your patient is comfortable. You want to reduce that anxiety. 00:40 You want to complete and document your neurovascular exam which includes checking capillary refill sensation and motor function Pre-procedure. 00:50 And you want to mark the injection sites at the webbing spaces on the dorsal aspect. 00:55 Identify proper landmarks of the base of the digit on both sides. 01:01 Prepare area with antiseptic solution using sterile technique and allow adequate drying time before proceeding. 01:10 These are some pictures looking at both the dorsal and the volar nerve intervention. 01:20 You're going to draw up 3 to 4 cc's of lidocaine. 01:24 And again use caution whether you use epinephrine in your lidocaine. 01:29 Insert the needle perpendicular to the skin at the dorsal webspace. 01:34 Advance to the appropriate depth about 5 to 10mm while aspirating. 01:39 Inject 1 to 1 .5 cc's slowly while withdrawing the needle. 01:45 And you're going to repeat this on the opposite side of the digit. 01:49 You're going to massage the area gently to distribute the anesthetic. 01:54 You're going to wait 5 or 10 minutes for full effect, and then you're going to proceed to the next procedure. 02:02 You're going to document post-procedure the neurovascular checks. 02:06 Again, you're going to compare to the pre-procedure exam findings of the neurovascular exam, which include checking the capillary refill, the sensation and motor function. 02:18 Remember that you may have 2 to 8 hours before they receive full sensation back after using the lidocaine.
