Ultimately you should not use more than 20mg 1% lidocaine in an adult. You know that you have used enough if the infiltrated skin is raised and pale. Check sensation by light pin prick prior to starting the suturing.
ilovecarly84....The reason for injecting and withdrawing is to ensure the local anaesthetic is infiltrated equally, or else if you take the needle too far and just inject there and THEN withdraw, the chances are the local aneasthesia may not numb the whole wound vertically.As the lecturer mentions,as you withdraw the needle while injecting, U see yellow colouration of the skin,and the skin rises slightely, thus indicating the local has spread at that area under the skin. Hope this helps, x
Interesting. I did suturing during my time in the Air Force and was instructed to use a 27g needle and to insert through the wound edge into tissues running parallel as to minimize damage to healthy tissues. Also, they failed to mention that if the wound is longer than the needle, to insert in an area already anesthetized to provide overlapping coverage.
I prefer to do a couple things different; for example I like to palm the hemostat and use my thumb only. Of course this is your technique... Thank You for your video!
I'm medical student from Belgium.
Your technique is very nice. I use the exact same one.
I was wondering how do you guys know how much to inject?
Is it based on the sight of the skin raising?

what is the point of injecting as you WITHDRAW? why not just inject and then withdraw?
